Amazon Refund Profit Leakage Calculator
What are Amazon refunds actually costing your business? This goes beyond refunded revenue to estimate the product cost and return-related costs you don’t get back - and, if you set a target refund rate, what reducing refunds could potentially be worth in contribution per month.
Your refund numbers
Total Amazon revenue for the period. Used only for context (leakage as a % of sales), never folded into the leakage figure itself.
Enter whichever one you have - we'll derive the other.
Your result
Enter your sales, units, and refund rate (or refunded units) to see your estimated refund-related contribution leakage.
How this is calculated
- Refunded units
- Units sold × Refund rate (or entered directly)
- Refunded revenue
- Refunded units × Average selling price
- Estimated product cost exposure
- Refunded units × (1 − Resellable %) × COGS per unit
- Return-related costs
- (Return-related costs + Non-recoverable fees per unit) × Refunded units
- Estimated contribution leakage
- Product cost exposure + Return-related costs
- Contribution potentially preserved
- (Refunded units − Target refunded units) × Contribution leakage per unit
This calculator does not use generic Amazon refund-rate benchmarks and never labels your refund rate “good” or “bad.” It's an estimate from the numbers you enter, not a review of your actual Seller Central account or a guaranteed outcome.
