This tool provides an educational estimate. Rules, rates and personal circumstances can change the answer. Review the assumptions before relying on a result. Report a correction.
Common mistakes to avoid
- Adding percentage discounts directly — two 20% discounts do not equal 40% off.
- Assuming stacked discounts are additive — a 20% off coupon on a 30% sale is 44% total, not 50%.
Frequently asked questions
Do stacked discounts add up?
No. A 20% sale followed by an extra 10% off coupon is 28% total, not 30%. Each discount is applied to the already-reduced price, not the original.
