• You can also reverse it: enter the original and sale price to find out what percentage was knocked off

• Works for any percentage reduction: sale prices, supplier discounts, VAT removal, and more
• Completely free, no account or signup needed

A percentage off calculator removes the mental arithmetic from sale shopping. You enter the original price and the discount percentage, and the tool instantly shows you both the saving and the final price you actually pay. No formula memorising, no wrong estimates at the checkout.

How to Use the Calculator

Open the percent off calculator and type the original price into the first field — say £120 — then type the discount percentage into the second field — say 25%. The result appears immediately: you save £30 and pay £90. You can also reverse it: enter the original and the sale price to find what percentage was knocked off. Useful for checking whether a "sale" is as generous as the tag claims.

When to Use This Calculator

Sale shopping: Retailers display discount percentages because the final price looks smaller. Entering both numbers here confirms the actual saving before you commit.

Stacked discounts: Black Friday deals often layer discounts — 20% off, then an extra 10% on top. Apply each percentage separately in the calculator to track your running price. A 20% then 10% discount is not the same as 30% off.

Business pricing: If a supplier quotes 15% off their list price, checking the net invoice figure takes seconds. Run the original price through here before approving the payment.

Clearance pricing: Sellers can enter a cost price and a target discount to find the lowest acceptable sale price without going below margin.

Frequently Asked Questions

How do I calculate 20 percent off a price? Multiply the original price by 0.20 to get the discount amount, then subtract it. For a £50 item: 50 × 0.20 = £10 off, so you pay £40. The percent off calculator handles this in one step — enter 50 and 20 and it shows both figures.

How do I work out what percentage off was applied? Subtract the sale price from the original to find the saving. Divide the saving by the original price, then multiply by 100. If a jacket dropped from £80 to £60, the saving is £20. So: 20 ÷ 80 × 100 = 25% off.

Does a 50% discount and then another 50% off mean the item is free? No. The second percentage applies to the already-reduced price, not the original. 50% off £100 gives £50. Another 50% off £50 gives £25 — not zero. Stack your discounts in the calculator one at a time to see the true final price.

Can I use this for VAT calculations too? The percent off calculator works for any percentage reduction, including removing a tax rate from a gross price. For VAT-specific breakdowns showing the net and tax separately, the VAT calculator is built for exactly that.

The percent off calculator is free and returns accurate results to two decimal places — no account required. You might also find the VAT calculator and commission calculator useful for related financial tasks.
