Price Increase Calculator

Break-even volume loss = increase ÷ (new profit per unit ÷ new price expressed against old profit). In practice: raising a $40 price to $44 with a $24 cost lifts unit profit from $16 to $20, so you can lose up to 20% of unit sales and earn the same total profit. Most well-executed increases lose far less than that — demand is usually less elastic than merchants fear.

Because the increase applies to the whole price but flows entirely to the thin profit slice. On a $40 product with $24 of cost, price rises 10% but the $4 lands on a $16 profit base — a 25% profit jump. The thinner your current margin, the more dramatic the leverage: at a 20% margin, a 10% price increase raises per-unit profit by 50%.

Raise in small steps rather than one jump, test on a subset of products or traffic first, and never apologize in the product page copy. Grandfathering existing subscribers briefly, improving the offer visibly (better packaging, faster shipping), or repricing at a natural moment like a product refresh all reduce pushback. Watch conversion rate for two to four weeks before the next step.

Yes — and raise by more than the dollar amount of the cost increase if you want to keep the same margin percentage. If cost goes up $2 on a $40 product and you add exactly $2, your margin percentage falls because cost grew faster than price. To preserve the percentage, divide the new cost by (1 − your current margin) and price there instead.
