Examples
- $100 at 20% off: Discount amount $20. Final price $80.
- Stack two discounts: Apply sequentially: $100 → 20% off = $80, then 10% off $80 = $72 (effective 28% off, not 30%).
- Find percent off from a ticket: Original $49.99 and sale $42.49 → about 15% off and $7.50 saved.

Frequently asked questions
How do I calculate a discount?
Multiply the original price by (1 − discount% ÷ 100). For $100 at 20% off: $100 × 0.80 = $80. This discount calculator shows both the final price and the amount saved.
How do stacked discounts work?
Each percent applies to the price left after the previous discount - not to the original. $100 with 20% then 10% becomes $72 (28% effective), not $70. Use Stack discounts mode to compare coupon stacks before checkout.
How do I find what percentage off a sale price is?
Use Find % off mode: enter the original price and the sale price. Percent off = (original − sale) ÷ original × 100. Example: $100 → $80 is 20% off.
Can I use any currency?
Yes. The tool only uses numbers, so enter amounts in your currency. Results stay in the same units without adding a symbol.
How do I calculate a discount with tax?
First get the discounted price, then multiply by (1 + tax rate). Example: $80 after 20% off × 1.08 for 8% tax = $86.40. Check whether tax applies before or after the discount in your region - this tool shows the pre-tax discounted price.
What if the discount is more than 100%?
Discounts above 100% are not valid retail scenarios. The calculator can produce a zero or negative final price - treat anything over 100% as invalid for real sales.
Should I round sale prices to .99?
Many retailers round display prices to .99 for marketing psychology after computing the discounted amount. This tool shows exact math; apply rounding only when it matches your store policy.
Can I compare several discount tiers?
Yes. Run 20%, 30%, and 50% off (or stack two coupons) to compare final price and savings before you publish a Black Friday or checkout promotion.
