Short example
A $40.00 product at 20% off sells for $32.00. With $10.00 product cost, $5.00 shipping, 9.4% combined fees, and $0.30 fixed fee, the discounted sale still keeps roughly $13.69 in profit (~42.8% margin).
All calculations are estimates based on average platform fees. Real profits may vary depending on category, ads, and shipping.

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
Sale profit = (Price × (1 − Discount%)) − Cost − Fees on sale price − Ads
Worked example
$40 product, $12 cost, ~13% fees, $2 ads, 20% off.
- Sale price = 40 × 0.80 = $32
- Fees on sale = ~$4.16
- Profit = 32 − 12 − 4.16 − 2 = $13.84
Answer: $13.84 profit (~43% margin)
How it works
A discount comes straight out of your margin. A 20% discount often eats 40–60% of a healthy profit because your fixed costs (product, shipping) don't shrink with the price.
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
- Treating a 20% discount as a 20% profit hit — it's usually much bigger.
- Ignoring that fees drop slightly along with the price, but product cost does not.
- Discounting past break-even 'to move volume' without measuring the loss.
