Discount & Percentage Calculator
Enter the original price and a discount percentage to see the final price and how much you save. Free, no sign-up.
The formula
Final price = original price × (1 − discount ÷ 100). The amount you save is simply original price × discount ÷ 100. So a 25% discount on a $120 item saves $30 and leaves $90 to pay. Handy for sale planning, quotes, and quick checkout maths.
