What it means
Reversal Rate is the percentage of conversions that get reversed after tracking — through refunds, cancellations, duplicate orders or validation failures. A high reversal rate erodes real earnings, so experienced affiliates weigh it alongside headline payout and EPC.
Reversal rate is the share of tracked conversions that are later cancelled, rejected, or refunded, calculated as reversed conversions divided by total tracked conversions times 100. It measures the gap between what tracking initially records and what ultimately gets paid, capturing returns, chargebacks, duplicate leads, and fraud screening. A conversion counted at click time is only revenue once it survives this window.
The metric matters because headline conversion counts and EPC are provisional until reversals settle, so a source that looks strong can turn marginal after cancellations. Merchants and networks watch reversal rate to police quality and detect fraudulent or low-intent traffic, and affiliates watch it to see their true, payable earnings. It directly reshapes which traffic sources are actually worth running.
Acceptable levels are category-dependent: physical goods with generous return policies or fashion may run high, whereas digital products and lead-gen often sit in the low single digits. Compare a source's reversal rate against the programme average and your own history rather than a fixed ceiling. A sudden spike is usually a warning about traffic quality or a broken funnel.
The main pitfalls are timing and gaming. Reversals lag conversions, so a recent period can understate the true rate until its window closes, which flatters fresh campaigns. Some traffic sources also generate cheap conversions that convert on paper but reverse heavily, so judging a source before its reversals mature can lead you to scale exactly the wrong thing.
Formula
Reversal rate = Reversed conversions ÷ Total tracked conversions × 100Key points
- Share of tracked conversions later cancelled or rejected
- Turns provisional earnings into true payable revenue
- Covers refunds, chargebacks, duplicates, and fraud
- Acceptable level varies by product category
- Lag means recent periods understate the rate
Example
A campaign records 400 tracked conversions in a month, and 48 are later cancelled or refunded. Reversal rate = 48 ÷ 400 × 100 = 12 percent. If each approved conversion pays 25 dollars, expected commission drops from 10,000 dollars to 8,800 dollars once reversals settle.
