Short example
A product sells for $35.00 with ~15.8% combined fees, $0.30 fixed fee, $7.50 in other per-item costs, and a 25% target margin. Max sourcing price ≈ $13.24. Sourcing at $8.00 projects a ~$13.72 profit.
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
Max sourcing price = Selling price × (1 − Fee% − Margin%) − Non-product costs
Worked example
$35 sell price, ~15.8% fees, $7.80 in other per-item costs, 25% target margin.
- Fees = 35 × 0.158 = $5.53
- Desired profit = 35 × 0.25 = $8.75
- Max sourcing = 35 − 5.53 − 7.80 − 8.75 ≈ $12.92
Answer: ~$12.92 max buy price for a 25% margin
How it works
The math sellers hate to do at a garage sale. Knowing your max buy price before you get there means you can walk away cleanly instead of hoping it works out.
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
- Sourcing based on 'gut feel' instead of a hard number.
- Forgetting outbound shipping, ads, and prep in the target price.
- Chasing margin on cheap items where absolute profit is tiny.
