A practical pricing tool
What happens if you change your price?
Fewer sales do not always mean less revenue. Compare two prices, see the trade-off, and know what to test next.
These are assumptions, not a forecast. You choose the sales volume; the calculator does not predict it.
Use one offer, the same unit and periods of equal length. Enter net prices after discounts, excluding tax, in the same currency.
The same unit cost is used before and after. Leave blank to compare revenue only.
Your comparison
Scenario · not a predictionChanges above are relative to the “before” figures. Elasticity below uses midpoint changes.
Keep the same revenue
At the new price, you need at least
84 whole units / bookingsExact threshold: 83.3333
Maximum volume decrease: 16.67%
This preserves revenue only. It is not a profit break-even point.
Price elasticity
0.58Magnitude · midpoint methodLess responsive in this comparison
Volume changes proportionally less than price. This describes these two points, not every future price.

Turn the number into a next step
Try a lower sales-volume assumption as well. Before changing your price, speak to the right customer segment about value and willingness to pay, then test with a defined offer and review date.

How the calculation works
P is price; Q is volume. 1 means before, 2 means after. The result is shown as a magnitude when price and volume move in opposite directions.
E = [(Q₂ − Q₁) / ((Q₁ + Q₂) / 2)]
÷ [(P₂ − P₁) / ((P₁ + P₂) / 2)]Actual results can also change with advertising, seasonality, product changes or customer mix. Subscription growth is not the same as retention. This is a two-point comparison, not a causal estimate or an optimal-price recommendation.
