A price increase almost always pays off even if you lose a few customers — the question is how many you can afford to lose. Enter your numbers and this shows the profit impact and the exact break-even volume drop.

The tipping points around your result — so you know the conditions, not just the answer:
Contribution margin = price − variable cost. Your monthly profit contribution is that margin × units sold. Raising the price widens the margin on every remaining unit.
Break-even volume drop = the percentage of sales you can lose before the higher margin no longer offsets the lost volume: 1 − (old margin ÷ new margin). As long as you lose less than that, the increase adds profit.
A planning estimate from your inputs — not pricing advice. Real demand response varies; test increases where you can and watch how customers actually react.
More than most people expect. Because a higher price increases the margin on every remaining sale, there's a break-even volume drop — 1 minus old margin over new margin — that you can absorb before profit falls. This tool computes that exact percentage for your numbers.
Raising prices flows almost entirely to profit, while new customers carry acquisition and delivery costs — so a price increase is usually the faster profit lever if you can hold most of your volume. The break-even drop tells you how much room you have before that changes.
Raise gradually, communicate the value, grandfather loyal customers where it makes sense, and watch the break-even threshold this tool gives you. If you lose fewer customers than that percentage, you come out ahead — and most well-run increases lose far fewer.
