Free Marketing Efficiency Ratio (MER) Calculator
Marketing Efficiency Ratio (MER) is a calculation to determine how effective your marketing efforts are at high-level. This metric helps you understand how healthy your marketing program is and if it is sustainable. MER is calculated by dividing your businesses revenue by your total marketing expenses.
First, type in a time frame to include with your calculation. Next, input all of your marketing related expenses. Finally, enter the revenue your business generated in that time frame to calculate your MER.
A MER of 3 means you make $3 for every $1 of marketing expense. Use this number for benchmarking your performance and forecasting what you need to spend to achieve your desired revenue.
