High Profit PotentialShort example
A 10% bump on a $30.00 product = $33.00. After the 10% fee change, profit per unit rises by ~$2.70. On 100 units that's ~$270.00 extra.
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
New price = Current × (1 + Increase%) OR Current + Increase$ · Old profit = Price − Cost − (Price × Fee% + Fixed) · New profit = same for new price · Increase = New profit − Old profit
Worked example
$30 current, 10% increase, $8 cost, 10% + $0.30 fee, 100 units.
- New price = $33
- Old profit = 30 − 8 − 3.30 = $18.70
- New profit = 33 − 8 − 3.60 = $21.40
- +$2.70/unit × 100 = $270 extra
Answer: $33 new price; ~$270 extra profit on 100 units
How it works
A price increase looks scary, but most of it becomes profit — fees only grow by the fee % of the increase, not the full amount. That's why even a small bump can meaningfully lift margin.
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 fees don't grow with price — they do, but proportionally.
- Rounding to a psychology-friendly number without checking margin.
- Ignoring the effect on volume — pair with Before/After Price Change for that.

FAQ
- How much can I raise the price?
- Depends on demand. A 5–10% bump on non-commodity items rarely hurts volume; test in small steps.
- How is this different from Before/After Price Change?
- This one shows the profit lift assuming stable volume. Before/After models both the price and a new sales quantity.
