How to use this calculator
- Enter your numbers in each field above — the calculator updates instantly as you type, so there's nothing to submit.
- Use your real figures when you have them, or sensible estimates while you're planning. If a field doesn't apply, leave it at zero.
- Compare the results, then change one input at a time to see how each lever (price, cost, fees, volume) moves the outcome.
Formula
Total cost = Refund + Product + Original ship + Return ship + Packaging + Non-refundable fees · Net loss = Total − Resale · Monthly = Net × Refunds/month
Worked example
$35 refund, $8 product, $5 orig ship, $6 return ship, $1.20 pkg, $1.50 fees, $0 resale, 3/mo.
- Total = 35 + 8 + 5 + 6 + 1.20 + 1.50 = $56.70
- Net = $56.70
- Monthly = 56.70 × 3 = $170.10
Answer: Each refund costs $56.70 → $170/month
How it works
A refund is not just 'give back the money'. Fees you already paid, return shipping you now cover, and packaging you can't reuse all vanish. The refund's real cost is often 1.5–2× the refund amount.
How to interpret your results
- Dollar values are shown per sale, per order, or per item unless a result is explicitly labelled monthly, weekly, or daily.
- Percentages (margin, ROI, conversion rate) are easier to compare across products and price points than raw dollars — use them when you benchmark.
- A positive result means you're ahead after the costs and fees you entered. A negative result means the current numbers don't work — change a lever (raise price, cut a cost, lower ad spend) and recalculate.
- Treat the output as a planning estimate, not a guarantee. Fees, taxes, and conversion rates shift over time — re-run the numbers whenever a key input changes.
Common mistakes
- Assuming the refund reverses all fees — many platforms keep some.
- Not counting return shipping when you're paying for it.
- Skipping resale value when the item is still sellable.
