A price increase can raise margin while lowering volume. A price cut can lift revenue while hurting contribution. Compare current and proposed price with unit volume, variable cost, fixed cost, and the volume needed to preserve profit before committing.

Formula
Projected profit = projected units x (proposed price - variable cost) - fixed costProjected units use the expected volume change. Break-even volume shows how many units are needed at the proposed price to preserve current gross profit.

Before relying on it
Details
A higher price usually improves contribution per unit unless the volume loss is large enough to offset it.
The key question is how much volume can fall before the proposed price stops protecting current gross profit.
Fixed cost does not change per unit, but it affects the net profit comparison after gross profit is calculated.
Benchmarks
A price increase can be profitable even with some volume loss if contribution per unit rises enough.
A discount usually needs enough extra unit volume to offset lower contribution per unit.
When the projected change is small, define rollout guardrails for conversion, churn, refunds, support load, and gross margin.

FAQ
Compare current revenue and contribution profit with projected revenue and contribution profit after the new price and expected volume change.
Use the break-even volume needed for the same gross profit. If current volume is above that number, the difference is the maximum modeled volume loss before gross profit falls.
Yes, but only if the extra unit volume offsets the lower contribution per unit. The calculator shows the projected revenue and profit side by side.
No. This is a planning estimate. Customer mix, churn, conversion, refunds, competitor response, seasonality, and packaging changes can affect the real result.
