Discount Calculator

Stop guessing sale prices—stack coupons accurately

Whether you’re timing a Black-Friday deal or just want to know if that “20 % off + €5 coupon” banner is really cheaper than a competing site, this calculator shows the final out-the-door price after every discount, cashback, and tax line-item. No more brain-crunching percentages or surprise totals at checkout.

Many stores apply coupons in a specific order—percentage, then fixed amount, then sales-tax/VAT. We follow the US FTC “Truth-in-Pricing” and EU Price-Reduction Directive methodology so your numbers match what appears on the receipt.

Example: 25 % off + €10 coupon on a €120 jacket (21 % VAT)

1. €120 × 25 % = €30 discount.
2. Subtotal €90 – €10 coupon = €80.
3. Add 21 % VAT → €16.80.
4. Final price = €96.80 (total savings €23.20).

FAQ

Does VAT apply before or after coupons?

In the EU, VAT is applied after all discounts. U.S. sales-tax rules vary by state but generally follow coupons first, tax last.

How do cashback portals fit in?

Enter the cashback as a percent-off coupon; the calculator stacks it correctly.
