Enter the original price and a discount percentage to instantly see how much you save and the final price after the discount is applied.
How discounts are calculated
The amount you save is the original price times the discount percentage. The final price is the original price minus that. For example, 25% off $80 saves $20, so you pay $60. Another way: multiply by (100 − discount) / 100, so 80 × 0.75 = $60.
Stacked discounts don't simply add up. 20% off followed by an extra 10% off is not 30% off: $100 becomes $80, then $72, a total discount of 28%. Apply each discount one after the other to get the real price.
Frequently asked questions
How is the final price calculated?
Final price = original price minus (original price times the discount percentage divided by 100).
Can I calculate multiple discounts stacked together?
This calculator handles a single discount at a time. For stacked discounts, apply the first discount, then use the resulting price as the new original price for the second discount.
How do I calculate 30% off a price?
Multiply the price by 0.70. For example, 30% off $50 is 50 × 0.70 = $35, saving $15.
How do I find the discount percentage from two prices?
Subtract the sale price from the original, divide by the original, and multiply by 100. $80 down to $60 is a 25% discount.
