Price Increase Calculator

See how many customers you can lose after a price increase and still earn the same profit.

Works in any currency. Cost per unit is what each extra sale costs you, such as materials, shipping and fees.

01 / MEANING

What your result means

A price increase raises the profit you make on every sale. That means you can sell to fewer customers and still end up with the same total profit.

The calculator shows how many can leave before the increase starts costing you money. If fewer leave, the increase pays off. If more leave, you earn less than before.

02 / FORMULA

The formula

Maximum customer loss = 1 − (price − cost) ÷ (new price − cost)

03 / EXAMPLE

Worked example

A shop sells 500 units a month at 100, and each unit costs 60. Profit per unit is 40, so monthly profit is 20,000.

After a 10% increase the price is 110 and profit per unit is 50. The shop now needs only 400 sales to earn the same 20,000. It can lose up to 100 customers, or 20%, and still break even.

04 / QUESTIONS

Questions

Does this include fixed costs like rent?

No. Fixed costs stay the same whether you sell more or less, so they don't change how many customers you can lose.

What if I lower my price instead?

Use the Discount Break-Even Calculator to see how many extra sales a lower price needs.

Is this financial advice?

No. It is a calculation for illustration. Your real result depends on how your customers react.
