How it works
Percent-off is the everyday discount calculation: take a percentage off a price to find what you pay and what you save. It's the same math as a discount — price times (1 minus the percentage).
Percent off
You pay = Price · (1 − percent ÷ 100) You save = Price · (percent ÷ 100)
- Price
- original price
- percent
- the percent taken off
Worked example
- Price = $120
- 40% off
- You save = 120 × 0.40 = $48
- You pay = 120 × 0.60
Save $48, pay $72.
Good to know
- For a quick estimate, 10% is the price with the decimal moved one place left — scale from there (30% = 3× that).
- Buy-one-get-one-50%-off averages to 25% off across the two items, not 50%.
- Clearance tags sometimes apply the percent to an already-reduced price, so check what the base is.

Frequently Asked Questions
How do I calculate a percent-off price?
Multiply the original price by (1 - discount/100). For example, 25% off an $80 item is 80 x 0.75 = $60. The amount you save is the original price times the discount percentage.
How do stacked discounts work?
Sequential discounts multiply rather than add. An extra 10% off an item already 20% off gives 0.80 x 0.90 = 0.72, which is 28% off the original price — not 30%.
How do I find the original price from a sale price?
Divide the sale price by (1 - discount/100). If something costs $42 after 30% off, the original price was 42 / 0.70 = $60.
Is sales tax applied before or after a discount?
Retail discounts almost always come first, so you pay tax on the reduced price. Treatment of manufacturer coupons can differ by state, but store markdowns are taxed on the discounted amount.
Is 50% off the same as buy-one-get-one-free?
Only if you actually need two items. BOGO averages to 50% off across two units, but if you only want one, a straight 50% discount saves you more money out of pocket.
