150.00% is the example result. Read it using the units and relationship stated below.
Compare the entered return with your marketing investment. Establish whether the return figure represents revenue or contribution before you interpret the percentage.
Define return before comparing campaigns
The implemented calculation subtracts the investment from the entered return and divides by investment. If you enter revenue, the result is a revenue-based return measure and excludes delivery costs absent from that figure.
When to use this result
Use a contribution-based return when the decision concerns profit after marketing. Include the marketing costs your comparison needs, such as media, production or agency fees, in the investment base.
Check before you act
Keep the same period and attribution definition across alternatives. A zero investment makes this percentage undefined.
Example with the supplied inputs
Marketing investment: 10000; Return generated: 25000. Result: 150.00%. The values are illustrative.
Compare one changed input
Marketing investment changes from 10000 to 11000. The result becomes 127.27%. All other inputs remain fixed.
Calculation rule
ROI (%) = (return − investment cost) ÷ investment cost × 100.
Inputs and output
| Input | Example value | Entry convention |
|---|---|---|
| Marketing investment | 10000 | Use the source quantity represented by marketing investment. Keep the counted population fixed and avoid mixing a unit value with a period total. |
| Return generated | 25000 | Use the source quantity represented by return generated. Keep the counted population fixed and avoid mixing a unit value with a period total. |
Output: 150.00% is the example result. Read it using the units and relationship stated below. Use the formula to distinguish a cash amount, count, percentage or ratio.
