Free Discount Calculator

Find the final price and the amount you save from a percentage discount.

You pay
60.00

You save 20.00 (25% off 80.00).

Quick answer

To calculate a discount, multiply the original price by the discount percentage divided by 100 to get the amount saved, then subtract it from the price. For example, 25% off $80 saves $20, for a final price of $60.

Formula & method

saved = price × (discount% ÷ 100);  final price = price − saved
  • price the original price
  • discount% the discount percentage, e.g. 25

Examples

Example 1: 25% off $80
Input
price = 80, discount = 25%
Result
Save $20.00, pay $60.00
Why
80 × 0.25 = 20; 80 − 20 = 60.
Example 2: 10% off $19.99
Input
price = 19.99, discount = 10%
Result
Save $2.00, pay $17.99
Why
19.99 × 0.10 = 1.999 ≈ 2.00.
Example 3: 70% clearance on $120
Input
price = 120, discount = 70%
Result
Save $84.00, pay $36.00
Why
120 × 0.70 = 84; 120 − 84 = 36.

When to use this tool

  • Checking a sale price while shopping.
  • Comparing two offers to see which saves more.
  • Working out a markdown for your own pricing.

Common mistakes

  • Stacking two discounts by adding the percentages. 20% then 10% off is not 30% off — it’s 28% off the original.
  • Confusing the amount saved with the final price.
  • Forgetting that tax is usually applied after the discount.

Frequently asked questions

How do I calculate a discount?

Multiply the original price by the discount percentage divided by 100 to get the savings, then subtract that from the price to get the final amount.

How do two stacked discounts work?

Apply them one after another. 20% off then 10% off a $100 item gives $80, then $72 — a 28% total discount, not 30%.

How do I find the original price from a sale price?

Divide the sale price by (1 − discount/100). For example, $60 after 25% off is 60 ÷ 0.75 = $80.

Is tax applied before or after the discount?

Usually after. The discount lowers the price first, then sales tax is calculated on the reduced amount.
