Stacked discounts multiply rather than add: 25% then 10% off is 32.5% off in total, not 35%. Tax is charged on the discounted price.

25% off 200 leaves 150, a saving of 50. Add a second 10% discount code and the price falls to 135: the combined saving is 65, an effective 32.50% off, not 35%. With 20% tax on the discounted price, the amount at the till is 162.
- Discounts are applied in sequence to the running price, which is how retailers apply stacked offers.
- Tax is calculated on the discounted price, matching most sales-tax rules; a few jurisdictions tax the pre-discount price on manufacturer coupons.
- All percents must be between 0 and 100.
The second discount applies to the already reduced price: 10% of 150 is 15, not 20. Stacked percentages multiply (0.75 x 0.90 = 0.675), giving 32.5% off overall.
About this tool
The Discount Calculator finds the real price after one or two stacked discounts, with optional sales tax on top, and reports what you actually save and the effective percent off. Stacked discounts are the classic shopping trap ('50% + 20% off!' is not 70% off), and this tool shows the true combined figure.
