6.67x is the example result. MER uses total revenue and total marketing spend, so it is a blended business measure rather than proof that one channel caused a sale.

Separating campaign efficiency from business profit
MER uses total revenue and total marketing spend, so it is a blended business measure rather than proof that one channel caused a sale. Campaign ratios depend on the event being counted. A click, a submitted form, a qualified opportunity and a paying customer are separate outcomes. Combine spend and events from the same campaign window before comparing acquisition costs.
Source and result record
For marketing efficiency ratio (mer), retain Total revenue, Total marketing spend together with the output. Record the date of the source values and the unit convention used in the form. That record separates a change in the underlying case from a change in how the information was entered. A saved result without its source values cannot show which assumption produced it.
Example with the supplied inputs
Total revenue: 100000; Total marketing spend: 15000. Result: 6.67x. The values are illustrative.
Compare one changed input
Total revenue changes from 100000 to 110000. The result becomes 7.33x. All other inputs remain fixed.
Calculation rule
Result = (([Total revenue]) ÷ ([Total marketing spend]))
Inputs and output
| Input | Example value | Entry convention |
|---|---|---|
| Total revenue | 100000 | Use total revenue on the currency and period basis shown by the formula. Keep gross amounts, net amounts and unit amounts distinct; the page does not fetch a price or exchange rate. |
| Total marketing spend | 15000 | Use total marketing spend on the currency and period basis shown by the formula. Keep gross amounts, net amounts and unit amounts distinct; the page does not fetch a price or exchange rate. |
Output: 6.67x is the example result. MER uses total revenue and total marketing spend, so it is a blended business measure rather than proof that one channel caused a sale. Use the formula to distinguish a cash amount, count, percentage or ratio.
How to use the page
Collect the inputs
Gather Total revenue, Total marketing spend. Use one period and the units shown in the form.
Run the calculation
Enter the values and select the action. The calculation rule above explains how the inputs produce the result.
Compare a scenario
Change Total revenue on its own, keeping the other inputs fixed. Read both results before changing another assumption.
Worked example
With the example inputs listed above, the result is 6.67x.
Change Total revenue from 100000 to 110000 while keeping every other value fixed. The result becomes 7.33x. This comparison isolates that input; it does not forecast how other variables will respond.
Check the stated formula, units and limits before using the result in a decision.
Keep the displayed formula, input units and model scope with the result. Corrections or questions can be sent through the request section on this page.
