Frequently Asked Questions About Discount Calculator
How do I calculate a discount?
Multiply the original price by the discount percentage to get the savings, then subtract that from the original price. For example, 25% off $80 is $20 saved, leaving a final price of $60. This tool does it instantly.
How do I work out the percentage off?
Divide the savings by the original price and multiply by 100. For example, saving $20 on an $80 item is 20 ÷ 80 × 100 = 25% off.
Does this include sales tax?
No. The discount calculator works on the listed price before tax. Add any applicable sales tax to the final price separately if you need the out-the-door cost.
Can I stack two discounts?
Stacked discounts apply one after another, not added together. A 50% then 10% discount is 50% off, then 10% off the reduced price — not 60% off. Run this tool twice to chain them accurately.
