Discount Calculator
Find the sale price after a percent-off discount, the amount you save, and the final price with tax. Supports a second stacked discount and quantity.
Item & discount
How to use this calculator
1. Enter the original price
The pre-discount price you see on the tag or listing. Set quantity if you're buying more than one of the same item.
2. Set the discount
Tap a preset chip (10โ70%) or type a custom value. The result updates instantly.
3. Stack a coupon (optional)
If a coupon applies after the on-shelf discount, enter it as the second percentage. The calculator applies them sequentially (not added).
4. Add tax if it matters
Sales tax is applied to the discounted subtotal โ most retailers tax the price you actually pay, not the original.
About discounts
Sequential vs. additive stacking
20% off + 10% off applied sequentially = 28% off total, not 30%. The second discount is applied to a smaller base. This calculator uses sequential stacking, which matches how most retailers handle "extra 10% at checkout" promotions.
"Up to" pricing
Promotions like "save up to 70%" use the maximum discount as a hook. The actual item you want might be at 20โ40%. Always check the per-item price.
Anchor pricing
Original prices are sometimes inflated to make a discount look bigger. Compare against the typical or "street" price for the item, not the listed "regular price".
