Free Price Increase Calculator: How Many Customers Can You Lose?
Raising prices feels risky because some customers may leave. But each sale at the higher price earns more, so you can often lose a few sales and still make the same profit. Enter your numbers to see how many.

How the math works
- Profit per sale = price − cost per sale.
- Profit now = sales × profit per sale.
- Sales needed at the new price = profit now ÷ new profit per sale, rounded up.
- Sales you could lose = sales now − sales needed. Fixed costs like rent or software don't change with the price, so they cancel out.
Example (made up): a $50 item that costs $20 to make and sell, 100 sales a month, so $3,000 profit. Raising the price 10% to $55 makes each sale earn $35. You'd need 86 sales to make the same $3,000, so you could lose up to 14 sales (14%) and break even on the change. If everyone stays, profit rises by $500.
This shows the math, not how your customers will react. Raising prices for new customers first, or with notice, can help. This is an estimate for planning, not business advice.
Check what each product should cost
The Product Pricing Calculator ($7) is a spreadsheet where you list your materials once (cost per unit works out from the pack price), then build up to 30 products from up to 4 materials each plus labor minutes and packaging/shipping. Set your hourly rate, target margin and one platform fee %, and it shows total cost, a price at your margin, 2x/4x reference prices, and the fee, profit and margin at the price you type. Works in Excel and Google Sheets. A pricing aid, not financial or tax advice.
