About the Discount & Markdown Calculator
A sale should attract buyers, not quietly wipe out your profit. Before you slap a percentage off, you need to know the sale price, the saving and — crucially — whether the discount still leaves you in the black.
This Discount and Markdown Calculator works out sale prices and savings, and shows whether a discount still leaves you in profit, so your promotions never cost you money.
How to use the Discount & Markdown Calculator
- Enter the original price and your cost.
- Enter the discount percentage.
- The tool shows the sale price and saving.
- Check whether you are still in profit.
Key features of the Discount & Markdown Calculator

How the Discount & Markdown Calculator works
These calculators use the standard, published fee structures of the major marketplaces and platforms — Shopify, Amazon FBA, Etsy and eBay — including referral, transaction, payment-processing and fulfilment fees. By combining those with your product cost and price, they show your real profit and margin per sale rather than just revenue.
All calculations run privately in your browser.
Tips & best practices
- Always check the profit that remains, not just the headline discount — a big percentage off a thin margin can mean a loss.
- Two stacked discounts do not simply add up, because the second applies to the already-reduced price.
- Build a little margin buffer so a promotion still contributes something, even on clearance.
Standards & accuracy
Based on the published fee structures of Shopify, Amazon, Etsy and eBay for realistic seller estimates.
Marketplace fees vary by plan, category and country and change over time, so treat results as close estimates. Confirm the exact figures against your own seller account before making decisions.
