Because it compares all revenue to all marketing spend, it reflects how the entire marketing ecosystem is performing \u2014 campaigns, organic traffic, referral channels, brand building, partnerships, and everything in between. This makes the <strong>marketing efficiency ratio<\/strong> one of the simplest ways to evaluate full-funnel performance.<\/p>\n<p>MER should include <strong>all revenue generated during the reporting period <\/strong>\u2014 paid, organic, referral, partner, and direct \u2014 as long as the revenue definition stays consistent across reporting windows. This ensures MER accurately reflects the full commercial impact of marketing activity.<\/p>\n<p><a href=\"https:\/\/www.hubspot.com\/products\/crm\/ai-crm\">HubSpot\u2019s Smart CRM<\/a> enables unified tracking and reporting of MER across channels by connecting revenue, spend, and attribution data in one place.<\/p>\n<h3><strong>What does MER measure?<\/strong><\/h3>\n<p><strong>MER measures overall marketing effectiveness, while <\/strong><strong><a href=\"https:\/\/blog.hubspot.com\/marketing\/return-on-ad-spend\">ROAS<\/a><\/strong><strong> (return on ad spend) measures channel-level return on ad spend<\/strong>, making MER especially valuable for cross-functional decisions. By capturing the entire revenue picture, MER cuts through attribution noise and helps executives understand whether marketing investments support sustainable growth. This broader view is particularly helpful for ecommerce brands, omnichannel marketers, revenue leaders, and B2B teams who report blended performance across long sales cycles. For this reason, the marketing efficiency ratio is now used widely in executive dashboards and board-level reporting.<\/p>\n<p><a href=\"https:\/\/www.hubspot.com\/products\/marketing?\">HubSpot\u2019s Marketing Hub<\/a> strengthens MER analysis by unifying revenue, spend, and attribution data in one connected system. When all marketing activity runs through a single platform, MER becomes more accurate and easier to interpret across channels.<\/p>\n<p>Even though MER provides an essential top-down view of efficiency, it cannot diagnose which individual campaigns or channels are driving performance. Instead, MER becomes most actionable when paired with metrics like ROAS, CAC, LTV, and channel-level revenue.<\/p>\n<p>At its core, the <strong>marketing efficiency ratio<\/strong> highlights whether marketing activity is generating sustainable, profitable revenue.<\/p>\n<p><strong>What MER Measures:<\/strong><\/p>\n<ul>\n<li>The full revenue impact of all marketing activity.<\/li>\n<li>Blended performance across paid, organic, and referral channels.<\/li>\n<li>Business-level efficiency and profitability.<\/li>\n<li>High-level effectiveness for budgeting, forecasting, and board reporting.<\/li>\n<\/ul>\n<p><strong>What MER Does <\/strong><strong><em>Not<\/em><\/strong><strong> Measure<\/strong><\/p>\n<ul>\n<li>Individual channel performance.<\/li>\n<li>The contribution of specific campaigns or creatives.<\/li>\n<li>Attribution patterns between marketing touchpoints.<\/li>\n<\/ul>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"data:image\/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==\" width=\"650\" height=\"374\" alt=\"chart showing what the marketing efficiency ratio measures and does not measure.\" style=\"margin-left: auto; margin-right: auto; display: block; width: 650px; height: auto; max-width: 100%;\" class=\"lazyload\" data-src=\"https:\/\/53.fs1.hubspotusercontent-na1.net\/hub\/53\/hubfs\/chart%20showing%20what%20the%20marketing%20efficiency%20ratio%20measures%20and%20does%20not%20measure..webp?width=650&amp;height=374&amp;name=chart%20showing%20what%20the%20marketing%20efficiency%20ratio%20measures%20and%20does%20not%20measure..webp\"><\/p>\n<p> <a><\/a> <\/p>\n<h2>How to Calculate Marketing Efficiency Ratio<\/h2>\n<p>The marketing efficiency ratio is calculated by dividing total revenue by total marketing spend for a specific period, producing a single blended metric that shows how efficiently marketing generates revenue. <strong>MER equals total revenue divided by total marketing spend, and this structure makes MER simple to calculate, compare, and standardize.<\/strong><\/p>\n<p><strong>The Marketing Efficiency Ratio Formula<\/strong><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"data:image\/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==\" width=\"650\" height=\"374\" alt=\"marketing efficiency ratio formula total revenue divided by total marketing spend\" style=\"margin-left: auto; margin-right: auto; display: block; width: 650px; height: auto; max-width: 100%;\" class=\"lazyload\" data-src=\"https:\/\/53.fs1.hubspotusercontent-na1.net\/hub\/53\/hubfs\/marketing%20efficiency%20ratio%20formula%20total%20revenue%20divided%20by%20total%20marketing%20spend.webp?width=650&amp;height=374&amp;name=marketing%20efficiency%20ratio%20formula%20total%20revenue%20divided%20by%20total%20marketing%20spend.webp\"><\/p>\n<p>MER relies on two consistent inputs: the total revenue generated during the period (gross or net, as long as it\u2019s defined the same way each time) and the total marketing spend associated with that same period. Because MER covers all revenue \u2014 not only attributed revenue \u2014 it provides a holistic signal that reflects the entire marketing ecosystem.<\/p>\n<p>Teams often revisit the <strong>marketing efficiency ratio<\/strong> weekly or monthly to monitor efficiency trends.<\/p>\n<p><strong>Example: MER Calculation<\/strong><\/p>\n<p>A business generates <strong>$500,000<\/strong> in total revenue in a quarter and invests <strong>$100,000<\/strong> in marketing during that same quarter.<\/p>\n<p>$500,000 \u00f7 $100,000 = MER of 5.0<\/p>\n<p>An MER of <strong>5.0<\/strong> means the business generated <strong>$5 in revenue for every $1 spent on marketing<\/strong>. This example illustrates that <strong>MER measures overall marketing effectiveness<\/strong>, not channel-level performance.<\/p>\n<p>A consistent <strong>marketing efficiency ratio<\/strong> allows organizations to compare efficiency across channels, seasons, or growth stages.<\/p>\n<p>Platforms like <a href=\"https:\/\/www.hubspot.com\/products\/marketing?\">HubSpot\u2019s Marketing Hub<\/a> simplify this calculation by centralizing campaign data, revenue attribution, and spend tracking inside the Smart CRM. With unified reporting, MER can be calculated consistently without pulling spreadsheets from multiple tools.<\/p>\n<h3><strong>Why Period Consistency Matters<\/strong><\/h3>\n<p>MER becomes unreliable if revenue and spend periods aren\u2019t aligned. Monthly MER helps teams identify short-term efficiency swings, while quarterly or annual MER works better for long-cycle B2B models. Keeping inputs consistent each time ensures MER remains stable and comparable across reporting periods.<\/p>\n<p><strong>Pro tip: <\/strong>Compare MER periods consistently: month-over-month, quarter-over-quarter, or year-over-year.<\/p>\n<h3><strong>How to Track the Marketing Efficiency Ratio in HubSpot<\/strong><\/h3>\n<p>Marketers can track the marketing efficiency ratio in HubSpot by combining the total revenue and total marketing spend inside a unified dashboard. <a href=\"https:\/\/www.hubspot.com\/products\/crm\/ai-crm\">HubSpot\u2019s Smart CRM<\/a> connects revenue, attribution, and spend data across channels, allowing teams to calculate MER using standard or custom reports. Teams typically create a single dashboard tile that divides total revenue by marketing spend for a selected period, then layer it with ROAS, CAC, and channel-level data for deeper analysis.<\/p>\n<p> <a><\/a> <\/p>\n<h2>Marketing Efficiency Ratio vs ROAS<\/h2>\n<p>MER differs from ROAS, which measures return on ad spend at the channel or campaign level. Because the marketing efficiency ratio measures overall <a href=\"https:\/\/blog.hubspot.com\/marketing\/easy-ways-to-measure-the-effectiveness-of-your-content\">marketing effectiveness<\/a> across all channels, the two metrics are complementary rather than interchangeable. MER measures overall efficiency, ROAS measures channel-level performance, and together they help allocate budgets more effectively. Understanding the difference between MER and ROAS is essential for comparing both metrics across channels and business models.<\/p>\n<h3><strong>What ROAS Measures<\/strong><\/h3>\n<p><a href=\"https:\/\/blog.hubspot.com\/marketing\/return-on-ad-spend\">ROAS (return on ad spend)<\/a> evaluates the efficiency of individual advertising channels or campaigns.<\/p>\n<p style=\"text-align: center;\">ROAS = Revenue Attributed to Ads \/ Ad Spend<\/p>\n<p>ROAS helps media buyers optimize budgets, bids, audiences, and creative assets. It offers granular insight into how specific tactics perform, but it cannot show whether the entire marketing function is generating sustainable returns.<\/p>\n<h3><strong>What MER Measures<\/strong><\/h3>\n<p>The MER calculator reflects the aggregate performance of all marketing activities by comparing total revenue to total marketing spend.<\/p>\n<p style=\"text-align: center;\">MER = Total Revenue \/ Total Marketing Spend<\/p>\n<p>This broader view helps executives understand whether total marketing investment is producing efficient top-line results, even when attribution is noisy or incomplete.<\/p>\n<h3><strong>How MER and ROAS Work Together<\/strong><\/h3>\n<p>Because <strong>MER measures overall marketing effectiveness while ROAS measures channel-level return on ad spend<\/strong>, teams get the most insight when using both metrics together. ROAS shows where spend should be allocated; MER shows whether total marketing spending is generating profitable revenue.<\/p>\n<p>High ROAS with declining MER may indicate overspending on upper-funnel channels, while steady MER with falling ROAS may signal channel saturation or diminishing returns.<\/p>\n<h3><strong>When to Use Each Metric<\/strong><\/h3>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"data:image\/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==\" width=\"650\" height=\"374\" alt=\"the mer - roas decision tree - when to use each formula\" style=\"margin-left: auto; margin-right: auto; display: block; width: 650px; height: auto; max-width: 100%;\" class=\"lazyload\" data-src=\"https:\/\/53.fs1.hubspotusercontent-na1.net\/hub\/53\/hubfs\/the%20mer%20-%20roas%20decision%20tree%20-%20when%20to%20use%20each%20formula.webp?width=650&amp;height=374&amp;name=the%20mer%20-%20roas%20decision%20tree%20-%20when%20to%20use%20each%20formula.webp\"><\/p>\n<ul>\n<li><strong>Use ROAS<\/strong> for media planning, channel optimization, creative testing, and performance marketing decisions.<\/li>\n<li><strong>Use MER<\/strong> for budget planning, forecasting, executive reporting, and evaluating whether marketing as a whole is contributing efficiently to revenue.<\/li>\n<\/ul>\n<p><a href=\"https:\/\/www.hubspot.com\/products\/marketing?\">Marketing Hub\u2019s attribution dashboards<\/a> make it easier to compare ROAS at the channel level with MER at the business level. Because both metrics sit inside the same reporting environment, teams can see which channels contribute meaningfully to total revenue and which only appear efficient in isolation.<\/p>\n<p> <a><\/a> <\/p>\n<h2>What is a good marketing efficiency ratio?<\/h2>\n<p>A \u201cgood\u201d marketing efficiency ratio depends entirely on the business model, margin profile, and growth strategy. There is no universal MER target because companies generate and deploy marketing spend differently, and those differences meaningfully change what efficiency looks like.<\/p>\n<p>A strong <strong>marketing efficiency ratio<\/strong> typically reflects aligned spend, healthy margins, and predictable customer behavior.<\/p>\n<p>Businesses with higher contribution margins can often sustain a higher MER threshold, while businesses with thinner margins typically need a more conservative efficiency baseline. This reinforces the principle that <strong>a good MER depends on business model, gross margin, and growth goals<\/strong>, not on a single benchmark.<\/p>\n<h3><strong>How to Assess MER by Business Model<\/strong><\/h3>\n<h4><strong>DTC and Ecommerce<\/strong><\/h4>\n<p>MER typically varies based on contribution margin, customer repeat behavior, and promotional intensity. Brands built on high-margin products or strong LTVs often operate with more room to scale spend while maintaining an efficient MER.<\/p>\n<h4><strong>Retail and Low-Margin CPG<\/strong><\/h4>\n<p>Lower margins usually require stricter efficiency targets. In these models, MER is often paired with contribution margin or cost-of-goods analysis to determine whether marketing spend supports profitable growth.<\/p>\n<h4><strong>B2B SaaS<\/strong><\/h4>\n<p>Long sales cycles can make closed-revenue MER misleading. Many companies use Pipeline MER \u2014 pipeline generated divided by marketing spend \u2014 to understand early-stage efficiency before deals close.<\/p>\n<h4><strong>Enterprise and High-Ticket B2B<\/strong><\/h4>\n<p>Deal velocity and deal size cause MER to fluctuate significantly. For these organizations, the CAC payback period or <a href=\"https:\/\/blog.hubspot.com\/service\/ltv-cac-ratio\">LTV-to-CAC ratio<\/a> often provides a more reliable efficiency signal than MER alone.<\/p>\n<p>Some organizations also track a sales and marketing efficiency ratio to evaluate combined commercial performance.

When paired with MER, CAC helps determine whether revenue efficiency aligns with sustainable profitability. High MER and rising CAC may signal inefficient scaling, while steady CAC with increasing MER indicates healthy growth. When CAC rises faster than the <strong>marketing efficiency ratio<\/strong>, efficiency is usually deteriorating.<\/p>\n<p><strong>Pro tip:<\/strong> Compare CAC trends with MER trends. Divergence between the two often reveals hidden channel inefficiencies.<\/p>\n<h3><strong>Return on Ad Spend (ROAS)<\/strong><\/h3>\n<p><a href=\"https:\/\/blog.hubspot.com\/marketing\/return-on-ad-spend\">ROAS<\/a> evaluates the revenue generated from specific ad campaigns. Because <strong>ROAS measures channel-level efficiency while MER measures overall effectiveness<\/strong>, the two metrics work best together. ROAS identifies which channels perform well; MER determines whether that performance contributes to total revenue growth.<\/p>\n<p>ROAS works best when evaluated alongside the <strong>marketing efficiency ratio<\/strong> to balance channel-level and business-level decision-making.<\/p>\n<p><strong>Pro tip:<\/strong> Prioritize channels where ROAS improves MER, not just channels with high ROAS in isolation.<\/p>\n<h3><strong>Customer Lifetime Value (LTV)<\/strong><\/h3>\n<p>Customer lifetime value measures the projected long-term value of a customer. Pairing LTV with MER helps teams understand whether efficient acquisition leads to profitable retention. High MER with low LTV can indicate short-term efficiency but weak long-term revenue health.<\/p>\n<p><strong>Pro tip:<\/strong> Evaluate LTV-to-CAC ratio alongside MER to confirm that efficient revenue today contributes to profitable growth tomorrow.<\/p>\n<h3><strong>Marketing Qualified Leads (MQLs) and Sales Qualified Leads (SQLs)<\/strong><\/h3>\n<p>Pipeline quality has a direct effect on revenue and, therefore, on MER. Tracking MQL and SQL volume \u2014 and their conversion rates \u2014 shows whether marketing investments generate meaningful demand that ultimately contributes to revenue.<\/p>\n<p><strong>Pro tip:<\/strong> When MER declines but MQL\/SQL quality drops simultaneously, the issue is likely upstream in targeting or messaging.<\/p>\n<h3><strong>Revenue per Visitor (RPV)<\/strong><\/h3>\n<p>Revenue per visitor measures how much value each site visitor generates. RPV directly influences MER by increasing total revenue without increasing spend. This makes RPV a strong indicator of conversion strength and content effectiveness.<\/p>\n<p><strong>Pro tip:<\/strong> Improving RPV often requires optimizing both site experience and content intent \u2014 start with your highest-traffic pages for maximum impact.<\/p>\n<p> <a><\/a> <\/p>\n<h2>Marketing Efficiency Ratio Pitfalls to Avoid<\/h2>\n<p>Marketing efficiency ratio becomes misleading when revenue and spend inputs are inconsistent, attribution is incomplete, or calculation windows aren\u2019t aligned. Avoiding these pitfalls ensures MER remains accurate and useful for decision-making.<\/p>\n<h3><strong>Mixing revenue sources or definitions inconsistently.<\/strong><\/h3>\n<p>MER depends on clean, consistent revenue inputs. If one period uses gross revenue and another uses net revenue \u2014 or if returns, discounts, or partner revenue are treated differently across periods \u2014 MER trends become unreliable. Because MER compares total revenue to total spend, inconsistent definitions can distort the metric.<\/p>\n<p><strong>Pro tip:<\/strong> Document the exact revenue definition used for MER and apply it identically every time.<\/p>\n<h3><strong>Measuring MER too infrequently or irregularly.<\/strong><\/h3>\n<p>Long reporting windows hide efficiency swings. Quarterly MER may mask short-term volatility, while ad-heavy periods often require more frequent monitoring. Regular intervals keep MER comparable and ensure early signals aren\u2019t missed.<\/p>\n<p><strong>Pro tip:<\/strong> Track MER monthly (and weekly during heavy spend cycles) to detect changes before they compound.<\/p>\n<h3><strong>Ignoring refunds, returns, or attribution gaps.<\/strong><\/h3>\n<p>Refunds and returns reduce actual revenue, and excluding them from MER artificially inflates performance. Attribution gaps \u2014 such as offline conversions or missing UTM parameters \u2014 also lead to incomplete revenue data.<\/p>\n<p><strong>Pro tip:<\/strong> Subtract returns from total revenue and ensure all channels consistently pass tracking parameters into your CRM.<\/p>\n<p> <a><\/a> <\/p>\n<h2>Frequently Asked Questions About Marketing Efficiency Ratio<\/h2>\n<h3><strong>Should organic and referral revenue be included in MER?<\/strong><\/h3>\n<p>Yes. MER includes all revenue generated during the reporting period \u2014 paid, organic, referral, partner-driven, or otherwise \u2014 as long as the revenue definition remains consistent across reporting windows. This approach supports the core principle that MER measures overall marketing effectiveness across all channels.<\/p>\n<h3><strong>How often should MER be calculated?<\/strong><\/h3>\n<p>Most organizations calculate MER monthly to keep the metric stable, comparable, and sensitive to meaningful changes in spend or revenue. Teams that run heavy ad cycles or large campaign launches often evaluate MER weekly to detect efficiency shifts earlier. Many teams use <a href=\"https:\/\/www.hubspot.com\/products\/marketing?\">Marketing Hub dashboards<\/a> to monitor MER automatically at weekly or monthly intervals.<\/p>\n<h3><strong>How do returns and refunds affect MER?<\/strong><\/h3>\n<p>Returns and refunds reduce actual revenue and should be subtracted before calculating MER. Excluding them inflates total revenue and leads to inaccuracies because MER is defined as total revenue divided by total marketing spend.<\/p>\n<h3><strong>How does MER apply to B2B SaaS with long sales cycles?<\/strong><\/h3>\n<p>For B2B SaaS, closed-won revenue may take months to materialize, making traditional MER less reliable. Many teams instead calculate <strong>Pipeline MER<\/strong>, comparing pipeline value created to marketing spend, which more accurately reflects efficiency within long, multi-stage buying cycles.<\/p>\n<h3><strong>Is there a difference between the media efficiency ratio and the marketing efficiency ratio?<\/strong><\/h3>\n<p>In most cases, the media efficiency ratio and the marketing efficiency ratio are used interchangeably. Marketing efficiency ratio is the broader term because it encompasses all marketing spend, not only media or advertising costs.<\/p>\n<p> <a><\/a> <\/p>\n<h2>Using MER to Build a More Efficient Marketing Engine<\/h2>\n<p>The marketing efficiency ratio offers a simple way to evaluate how effectively marketing investments generate revenue by comparing total revenue to total marketing spend. The marketing efficiency ratio cuts through channel-level noise, clarifies the impact of the entire marketing ecosystem, and supports better forecasting and budget planning.<\/p>\n<p>Because MER differs from ROAS \u2014 measuring overall effectiveness rather than campaign-level efficiency \u2014 it becomes most useful when paired with supporting metrics like CAC, LTV, ROAS, RPV, and lead quality. Improving MER requires increasing revenue per visitor, reducing wasted spend, and maintaining clean, unified data across channels, all of which become easier with connected reporting inside <a href=\"https:\/\/www.hubspot.com\/products\/crm\/ai-crm\">HubSpot\u2019s Smart CRM<\/a> and the <a href=\"https:\/\/www.hubspot.com\/products\/marketing?\">Marketing Hub<\/a>.<\/p>\n<p>From my perspective, having worked across marketing orgs that are constantly asked to prove ROI, MER is often the metric that finally broadens the conversation. It shifts the focus away from isolated channel performance and toward whether the entire marketing engine is aligned with commercial goals and driving growth.<\/p>\n<p><strong>MER becomes most valuable once teams stop treating it as a score and start treating it as a signal.<\/strong> It\u2019s the moment when leaders realize MER isn\u2019t a judgment on the marketing team, but a lens for making smarter decisions. The organizations that use MER well tend to revisit it consistently, layer it with complementary metrics, and build workflows that turn data into action. Those are the teams that improve efficiency without sacrificing momentum \u2014 and the ones that build growth engines capable of scaling predictably.<\/p>\n<p>The latest <em>State of Marketing Report<\/em> highlights exactly why this matters: Teams that use unified data, blended efficiency metrics, and cross-channel measurement are outperforming peers that rely on siloed reporting alone.
