How is this calculated?
% off: Saving = Original × percent ÷ 100; Sale price = Original − Saving
Amount off: Sale price = Original − Amount (the saving is capped at the original price)
Final price: Saving = Original − Sale price
Effective discount = Saving ÷ Original × 100
Three ways to express a discount
A discount can be a percentage off, a set amount off, or simply the new price. This calculator handles all three and always shows the same underlying result: what you pay and what you save.
Effective discount
When you know the original and sale prices, the effective discount is the saving as a percentage of the original. It is a quick way to compare offers that are advertised in different ways.
Discounts, margins, and tax
A discount changes the price a customer pays, which in turn affects your margin and the tax charged. Pair this with the profit margin and sales tax calculators to see the full effect of a promotion.
Frequently asked questions
What is a discount calculator?
It works out the sale price and the amount you save from an original price and a discount — whether that discount is given as a percentage off, a fixed amount off, or a target sale price.
How do I calculate a percentage discount?
Multiply the original price by the discount percentage divided by 100 to get the saving, then subtract it from the price. For example, 20% off $100 is $20 saved and an $80 sale price.
How do I find the discount percentage from a sale price?
Subtract the sale price from the original to get the saving, divide by the original, and multiply by 100. A price cut from $100 to $75 is a $25 saving, or a 25% discount. Use the “Final price” mode above.
How do I calculate a price after a discount?
Subtract the saving from the original price. This calculator shows the resulting sale price for a percentage off, an amount off, or a target price automatically.
What does “20% off” mean?
It means the price is reduced by 20% of its original value. On a $50 item, 20% off is a $10 reduction, giving a $40 price.
How do I calculate the total saving for multiple items?
Enter a quantity and the calculator multiplies the per-item original, sale, and saving to show totals for the whole purchase.
Can a discount be more than 100%?
A discount cannot reduce a price below zero, so this tool caps a percentage or amount discount at the full price — the most you can save is the original price itself, a 100% discount.
