Why stacked discounts do not simply add
Each discount applies to the price left after the previous discount. A 25% discount followed by 10% off is not 35% off. On $100, the first discount leaves $75 and the second removes $7.50, for a final price of $67.50 before tax.
That example produces an effective discount of 32.5%. Sales tax is normally applied after discounts, but rules and taxable amounts can vary by location and item.
This calculator provides arithmetic estimates, not tax advice. Check the displayed checkout total and local rules before purchasing.
