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
Profit/unit = Price − Cost − (Price × Fee% + Fixed) · Monthly = Profit/unit × Sales · Sales to match old profit = Old monthly ÷ New profit/unit
Worked example
Old $25 × 100 sales → New $30 × 85 sales, $8 + $2 costs, 10% + $0.30 fee.
- Old profit/unit ≈ $12.20 → $1,220/mo
- New profit/unit ≈ $16.70 → $1,419/mo
- Diff = +$199 monthly profit
Answer: New price adds ~$199 monthly profit even with 15% volume drop
How it works
Sellers over-fear price increases because they picture volume dropping and profit staying flat. In most non-commodity categories, a 10–20% price bump keeps most volume and lands almost pure profit.
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 volume doesn't change.
- Modeling a doom-scenario drop instead of a realistic one.
- Forgetting fees grow with price — but only by the fee % of the increase.
