Pricing impact
Price increase economics
Maximum volume loss preserves baseline total profit; it is not a demand forecast.
Maximum sales volume loss21.9%
The proposed price raises unit profit. Compare the maximum volume loss with a realistic demand estimate.

Method
How price increase impact is calculated
The calculator compares unit contribution at both prices, then solves for the sales volume that preserves profit.
1. Profit at each price
Fixed unit costs stay constant while percentage fees follow the actual price.
Unit profit = price − per-unit costs − price-based fees 2. Baseline total profit
Current unit profit is multiplied by current sales volume.
Baseline profit = current unit profit × baseline units 3. Allowed volume decline
Divide baseline profit by proposed unit profit to find the minimum sales volume.
Maximum volume loss = 1 − current profit per unit ÷ proposed profit per unit What this model answers
It calculates the sales decline you can absorb financially. It does not predict customer price sensitivity.
Keep the unit consistent
All prices, costs and volume values must describe the same product, order or bundle.
FAQ
Price increase calculator FAQ
How much can sales fall after a price increase?
The calculator divides current unit profit by proposed unit profit. One minus that ratio is the maximum percentage volume decline that preserves total profit.
Does a higher price always increase total profit?
No. Unit profit rises in this model, but total profit falls if sales volume declines beyond the calculated limit.
Why are payment fees recalculated?
Percentage payment and platform fees rise with the actual selling price, so only their rate stays constant.
Does this predict demand or elasticity?
No. Enter your own expected units to compare a demand scenario. The calculator makes no elasticity forecast.
Is my pricing data uploaded?
No. All price and cost calculations run locally in your browser.
