Why a small discount takes a big bite out of profit

A 20% coupon does not cut your profit by 20% — it usually cuts it by far more. The discount comes straight off the top of the sale, but your product cost and flat fees stay exactly the same, so the entire reduction lands on your profit line. On a typical handmade item, a 20% code can erase a third to half of the per-sale profit, which means you need dramatically more orders just to earn the same total money. This calculator shows those numbers before you launch the promotion, including the break-even point in extra sales. The fee figures are approximate defaults you can edit; check the platform's current fees; estimates only, not financial advice.

How to use it

Enter your item price and your total cost per sale (production or materials, packaging, and any postage you pay).
Pick percent off or a flat dollar amount, then enter your coupon's value.
Adjust the fee fields to match your platform: marketplace percentage, payment processing percent and fixed fee, plus any other flat fees such as a listing fee.
Enter roughly how many sales you make per month so the tool can translate the break-even into a real order count.
Read the cards: discounted price, new profit per sale, new margin, and the extra sales required to match your original total profit.

FAQ

Are fees charged on the full price or the discounted price?: On most marketplaces, percentage fees are charged on what the buyer actually pays, so this tool applies them to the discounted price. Flat fees are charged either way.
What does "Never" mean in the extra-sales card?: It means the discounted price no longer covers your cost and fees — every coupon sale loses money, so no amount of extra volume can catch up to your old total profit.
Should I include shipping?: If you charge for shipping and your platform takes fees on it, add it to the item price and put your postage in cost per sale. If you offer free shipping, just put the postage in cost.
Is my pricing data uploaded anywhere?: No. Everything is calculated in your browser; nothing is sent to a server or stored.
