Discount Calculator

How to calculate a discounted price

1. Enter the original price and choose its currency. Currency selection labels the amount; it does not convert it.
2. Enter the percentage removed from the price. For 20% off, enter 20, not 80.
3. If a second percentage reduction also applies, open Second discount, enable it and enter that percentage.
4. Read the price after discount and savings. Calculation details show the method; Copy result uses the current valid figures.

Useful discount calculations without a shopping dashboard

• Calculate the sale price from an original price and percentage off.
• See how much the entered discounts save against that original price.
• Optionally apply a second reduction to the already discounted price.
• Use explicit currency precision, including currencies with zero or three decimal places.
• Keep exact percentage arithmetic until the final display, with clear rounded and tiny-positive wording.

When this calculator helps

• Check the mathematical price of an item advertised with a percentage reduction.
• Estimate a second percentage reduction on a sale price, when both offers apply.
• Understand why two percentage reductions are not normally added together.

Understand percentage-off and successive reductions

Percentage off is the share removed. A 20% reduction leaves 80% of the original price. It is not the percentage still payable.

A second percentage reduction acts on the remaining price. For 20% off followed by 10% off, the remaining share is 0.8 × 0.9 = 0.72, so the combined reduction is 28%, not 30%.

Only enable the second reduction when the offers can be used together. The calculator applies the entered arithmetic; it does not inspect terms or verify eligibility.

Currency is independent of interface language. Prices must use the selected currency's supported decimal precision. Switching currency retains the number and performs no exchange-rate conversion.

Intermediate prices are not rounded. Price and savings are derived from the exact factors and rounded independently for display. A merchant using a different sequence or stage-rounding policy may charge a different amount.

Extra taxes, delivery and fees are not calculated. If your original price already contains a charge, that entered amount remains the mathematical discount base; the tool does not separate it.

Worked discount examples

An original EUR 80.00 price with 25% off becomes EUR 60.00. The amount saved is EUR 20.00.

EUR 100.00 with 20% off followed by another 10% off becomes EUR 72.00. Savings are EUR 28.00 and the combined reduction is 28%.

EUR 88.80 with 12.5% off becomes EUR 77.70, saving EUR 11.10.

EUR 99.99 with 50% off gives an exact price and exact savings of EUR 49.995 each. Both display as about EUR 50.00; their rounded sum differs from the original by EUR 0.01.

EUR 0.01 with 50% off has a positive exact price of EUR 0.005. It is shown as less than EUR 0.01, not as zero or a promise of a free item.

What the result does not decide

This is a mathematical price estimate, not a checkout quotation. A store's eligible base, promotion sequence or intermediate rounding can differ.

The second reduction is a percentage of the already reduced price. Fixed coupons, baskets, quantity deals, cashback, reverse-price and tax calculations are not included.

Amounts shown at currency precision use positive half-up display rounding, not cash-denomination or country-specific billing rules. Positive amounts below one display step are qualified rather than treated as zero.

No currency conversion, product-price history, discount authenticity check or promotion eligibility lookup is performed.

Your calculation inputs

Figures stay in page memory. The tool adds no account, upload, saved history or share link containing them. Copy happens only when requested.
