Discount Calculator

Quickly Calculate Sale Prices and Savings

Before you buy, know what you'll actually pay. Enter the original price, the discount percent, and (optionally) the sales tax percent to see how much you save and what the final price will be.

Formula

Final price = (Original × (1 − Discount/100)) × (1 + Tax/100)

Common Scenarios

• A $199 jacket at 25% off is $149.25 — a $49.75 saving.
• A $1,200 TV at 15% off plus 8% tax comes to $1,101.60.
• Buy-one-get-one-free is equivalent to a 50% discount on the pair.

Tips for Smart Shopping

• Always calculate the discount on the pre-tax price — that's how stores compute it too.
• A "50% off" stacked coupon on a 50% sale is not 100% off; it's 75% off. Percentages multiply, not add.
• Compare unit price (per oz, per kg, per 100 ml) for truly fair comparisons, especially at grocery stores.
