Meta Ads Profit Calculator
Split Meta's reported ROAS into the true profit underneath — platform attribution overstates conversions, and the gap is exactly the profit you would have celebrated that never existed.

What this result does not account for
- The overstatement input must come from your own holdout tests.
- Verified CVR assumes your order system is the ground truth.
- No creative-level or audience-level decomposition.
In short: 18,750 of spend reports 546 orders but verifies at 462: true ROAS is 3.1539x against a reported 3.7274x, 10,752 of revenue and 4,515.84 of profit are phantom, and verified orders can fall 24.51% short before the month turns loss-making.
Formula
verified orders = impressions × CTR × verified CVR
reported = verified × (1 + overstatement)
phantom profit = (reported − verified) × contribution
headroom = budget ÷ (verified orders × contribution)
[('verified', 'counted in your own system, not the pixel'), ('overstatement', 'how far the platform runs ahead of reality'), ('phantom', 'profit in the report, not in the bank'), ('headroom', 'the overstatement the account can survive')]
Worked Example
- Cascade budget → impressions → clicks → verified orders.
- Inflate by the attribution gap for what Ads Manager claims.
- Price verified orders at contribution for true profit.
- Convert the phantom orders into phantom profit.
- Compute the overstatement headroom and stress the ROAS at 80% lift.
18,750 at a 12.50 CPM is 1,500,000 impressions; 1.10% CTR makes 16,500 clicks and a 2.8% verified CVR makes 462 orders — 59,136 of revenue, a 3.1539x true ROAS and 6,087.12 of true profit. Ads Manager claims 546: an 18.1818% overstatement, 84 phantom orders, 10,752 of phantom revenue and 4,515.84 of phantom profit. The account breaks even with verified orders down to 75.49% of today's count, so it survives a 24.51% fall — and at an 80% verified lift the incremental ROAS is still 2.5231x.
Strengths & Limits Of This Model
Where this engine is strong
- Separates the reporting layer from the profit layer
- Prices phantom profit in currency, not adjectives
- Derives a tolerance the measured gap can be judged against
Where it stops
- Needs a holdout to populate honestly
- Account-level only

Methodology & Editorial Standards
Impressions, clicks and verified orders follow the same cascade as every channel page. The attribution gap is entered as a measured (reported − verified) ÷ verified percentage and applied only to the reporting layer — profit is always computed on verified orders. The headroom card derives the verified-order floor at which the account breaks even, so the measured gap can be compared against a tolerance instead of intuition, and the stress card re-prices ROAS at an 80% incremental share.
Computation runs in IEEE-754 double precision at full internal precision; rounding to two decimal places occurs strictly at the display layer, so no cumulative drift enters the result. All monetary outputs use accounting presentation — grouped thousands, two decimals, negatives in parentheses — so figures can be transcribed directly into a model or working paper. Division-by-zero and out-of-domain inputs return an em-dash rather than a misleading number.

Meta Ads Profit Calculator — 10 Expert FAQs
10 analyst-written answers to the questions practitioners actually ask — optimised for voice and answer-engine retrieval.
Why does Meta report more conversions than my store counts?
Ads Manager counts every conversion attachable to an ad within its attribution window, including sales that would have happened without the ad and cross-device duplicates. Verified counts from your own order system are the floor; the platform number is a ceiling around them.
What is a typical attribution overstatement?
It varies enormously by account mix — accounts heavy on retargeting and brand terms overstate far more than prospect-heavy ones. The honest practice is to measure your own gap with a holdout and enter it here, not to borrow someone else's number.
Does a high reported ROAS mean the campaign is good?
It means the pixel is busy. Compare reported against verified on the same period: if the gap is stable, the RELATIVE ranking of creatives inside the account is still usable even while the absolute number is inflated.
How do I measure my own overstatement?
Geo holdouts or platform-experiments give an incremental lift figure; divide it into reported conversions and the quotient is the verified share. Even a quarterly test converts this page from an assumption into a measurement.
What is overstatement headroom?
The percentage by which the platform could overstate before the account stops breaking even on contribution. Here the floor is verified orders at 75.49% of today's count — 24.51% of headroom against an 18.18% measured gap.
Should I optimise toward reported ROAS anyway?
For ranking creatives and audiences inside the account, yes — the bias is shared, so comparisons hold. For budget level decisions, no — those need the verified contribution line this page computes.
Why is the CPA here different from Ads Manager's?
This CPA divides spend by verified orders; Ads Manager divides by reported orders. The distance between them is the same attribution gap wearing a cost-per-action costume.
Does the 7-day-click window overstate most?
Longer windows and view-through attribution both increase counts. Tightening the window is the cheapest calibration available, and it changes the reported number immediately while changing true performance not at all.
What if the verified gap exceeds the headroom?
Then the account is loss-making however good the report looks: phantom profit has absorbed the real margin. Cut into retargeting and brand spend first — that is where non-incremental conversions concentrate.
Is 80% incrementality a standard assumption?
It is a stress level, not a finding — a deliberately pessimistic share to test whether the account survives honest doubt. Measure your own; the card exists so the answer is already on the table when the test lands.
