Ad Leak Estimator
A rough estimate of the monthly budget that a tracking-loss rate can misdirect. Set your numbers, pick an assumed loss rate, and the tool applies two simple formulas. It runs in your browser — nothing you enter leaves this page.
This is a rough estimate based on the loss rate you choose, not a measurement of your account.
How this is calculated
The tool applies two formulas to the numbers you enter:
- Estimated true ROAS = reported ROAS × (1 − loss rate)
- Estimated wasted spend = monthly spend × loss rate
The loss rate is an assumption you pick, not a measurement. The three presets are illustrative example scenarios, not measured industry averages: a minor checkout gap, a typical pixel-plus-CAPI double-fire, and a severe tracking failure. Your real loss rate can only be found by reconciling reported conversions against your actual orders.
Worked example. At $40,000/month of spend, a reported 3.8x ROAS, and a 25% assumed loss rate:
- Estimated true ROAS = 3.8 × (1 − 0.25) = 2.85
- Estimated wasted spend = $40,000 × 0.25 = $10,000
Limitations
- It is a rough arithmetic model, not a measurement of your account.
- It assumes the loss rate you select; it cannot detect your real one.
- It ignores differences in how each platform attributes conversions (view-through, attribution windows, modeling).
- It is not a substitute for an order-level reconciliation.
