How is the discount calculated?

The amount saved equals the original price multiplied by the percent off divided by 100. The final price is the original price minus that saved amount.

What does 'You Pay (% of original)' mean?

It is the share of the original price you still pay after the discount. For example, 25% off means you pay 75% of the original price.

Can I enter a discount over 100%?

No. A percent off above 100 would make the price negative, so keep the value between 0 and 100.

Does this include tax?

No. This calculator applies only the discount. Any sales tax or VAT would be added separately on top of the final price.

What the Percent Off Calculator Does

This percent off calculator turns a list price and a discount percentage into the amount you save and the final sale price. Enter the original price and the percent off, and it instantly shows both numbers so you don't have to do the math in your head at the register or while online shopping.

It's built for shoppers comparing deals, store staff applying markdowns, and anyone budgeting around a sale. Because it works with any currency, the same steps apply whether you're checking a discount in dollars, euros, or pounds.

How a Percent Off Is Calculated

A percentage off is simply a fraction of the original price subtracted from that price. The calculator uses two short steps:

Amount saved = price x (percent off / 100)
Final price = price - amount saved

Why the Formula Works

Dividing the percent by 100 converts it into a decimal multiplier. A 25% discount becomes 0.25, and multiplying the price by 0.25 gives the share of the price you don't pay.

You can also reach the final price in one step by multiplying the price by (100 - percent) / 100. For 25% off, that means paying 75% of the original: price x 0.75. Both routes give the identical result, so use whichever is easier to follow.

Worked Example

Suppose a jacket is listed at 80.00 and the sign says 25% off.

Amount saved = 80 x (25 / 100) = 80 x 0.25 = 20.00. Final price = 80 - 20 = 60.00. So you save 20.00 and pay 60.00. The one-step check confirms it: 80 x 0.75 = 60.00.

For a quick mental estimate, 10% of 80 is 8, so 20% is 16 and 25% is 20 — close enough to sanity-check the calculator before you buy.

Tips and Common Mistakes

A few errors come up again and again when people calculate discounts by hand. Watch for these:

Don't stack percentages by adding them. "30% off then an extra 20%" is not 50% off — the second discount applies to the already-reduced price, so it's 30% off, then 20% off that, giving 56% off in total.
Tax and shipping are usually added after the discount, so the final price here is the pre-tax subtotal, not what you pay at checkout.
Confirm whether the discount is a percent off or a flat amount off; "$25 off" and "25% off" rarely match.
Round only at the end. Rounding the saved amount too early can shift the final price by a cent or two.

Factors That Affect Your Final Price

The headline discount is just one input. Coupons, loyalty points, store credit, or member pricing may apply on top of the percent off and change the order of operations. Some retailers also exclude already-marked-down items from extra promotions.

If you need the amount saved expressed as a percentage of a different number — for example, savings versus what you actually paid rather than the list price — recalculate using that base, since the same dollar saving represents a larger percentage of the lower number.
