Frequently Asked Questions
How do you calculate a 20% discount on $100?
Multiply the price by the discount rate: $100 × 0.20 = $20 discount. Subtract from the original: $100 − $20 = $80 final price. Or use the shortcut: $100 × (1 − 0.20) = $100 × 0.80 = $80.
Is a 30% discount better than 25% off plus an extra 10% off?
Not always — stacked discounts don't add up. 25% off then 10% off the reduced price equals 1 − (0.75 × 0.90) = 1 − 0.675 = 32.5% total discount, which beats a flat 30%. Always multiply the remaining-price factors to compare.
Should sales tax be calculated before or after the discount?
In most U.S. states, sales tax applies to the discounted (final) price, not the original. So calculate the discount first, then apply tax to the reduced amount. Our calculator handles this automatically when you enter a tax rate.
