What this calculator estimates
Estimate Facebook or Meta Ads traffic, conversions, revenue, ROAS and ROI from spend, CPM and conversion assumptions.
How to use it
Enter Advertising spend ($); Average CPM ($); Click-through rate (%); Website conversion rate (%); Average revenue per conversion ($); Gross margin (%); Other campaign and creative costs ($). Select Calculate to update the results.
How the calculation works
The calculator estimates traffic from the entered cost metric, applies click-through and conversion assumptions, then calculates revenue, gross profit and ROI after advertising and other costs.
Worked example: starting scenario
| Advertising spend ($) | 12000 |
|---|---|
| Average CPM ($) | 18 |
| Click-through rate (%) | 1.4 |
| Website conversion rate (%) | 3.5 |
| Average revenue per conversion ($) | 550 |
| Gross margin (%) | 65 |
| Other campaign and creative costs ($) | 1500 |
| Estimated advertising ROI | 765.06% |
|---|---|
| Estimated clicks | 9,333 |
| Estimated conversions | 326.7 |
| Estimated revenue and ROAS | $179,666.67 / 14.97x |
| Estimated contribution profit | $103,283.33 |
Important limitations
Attribution, platform reporting, view-through conversions, refunds, repeat purchases, taxes, creative fatigue and incrementality can change actual results.
ROI is undefined when the total modeled cost is zero. The associated cash-flow amounts can still be calculated; an undefined return percentage is not a zero-percent return.
From impressions to profit
The Facebook scenario starts with ad spend and the entered CPM, then estimates impressions, clicks and conversions using the entered rates. These are expectations, so fractional conversions are valid averages rather than literal completed orders. They are not platform performance benchmarks.
Revenue is expected conversions × average order value. Gross margin converts that revenue to contribution before advertising and other campaign costs. ROI uses contribution minus campaign costs, not revenue alone. For $1,000 spend, $10 CPM, 1% click-through and 2% conversion, the model expects 100,000 impressions, 1,000 clicks and 20 conversions. At $100 per order and 50% margin, $2,000 revenue supplies $1,000 contribution and exactly breaks even before other campaign costs.
CPM, click-through and conversion are separate stages
CPM sets the cost for 1,000 impressions. Click-through rate converts impressions to expected clicks, and conversion rate converts those clicks to the selected outcome. In this one-outcome-per-click model both percentages run from 0% to 100%. Revenue uses the entered order value, while profit uses gross margin and subtracts advertising and other campaign costs. A revenue multiple above 1 does not alone prove the campaign is profitable.
