Marketing Efficiency Ratio Calculator
Enter your total revenue and total marketing spend to instantly calculate your Marketing Efficiency Ratio — the blended view of how hard your entire marketing budget is working.
How to Use This Calculator
MER is the blended ROAS across your entire marketing mix. It is a top-down health metric that accounts for all channels — paid, organic, and referral.
Enter your total revenue
Use your business total revenue for the period — not just revenue from one channel. MER is a whole-business metric, not a channel metric.
Enter your total marketing spend
Include all marketing spend: paid ads, agency fees, tools, events, content, SEO, email, and any other acquisition or retention spend.
Read your MER
A MER of 4× means you generated 4 units of revenue for every 1 unit of marketing spend. This includes the halo effect of all channels working together.
Use MER alongside channel ROAS
MER gives you the blended picture. Use it alongside channel-level ROAS to identify where to shift budget and which channels are punching above their weight.
