Results explained
Discounts apply sequentially to the remaining price, not always to the original. Tax, when entered, applies after discounts on the reduced subtotal.
Quick reference: stacked discounts
25% off $80 leaves $60 before tax.
| Item | Detail |
|---|---|
| First % off | price × (1 − d₁) |
| Second % off | applied to reduced price, not original |
| 25% then 10% | not the same as 35% off |
| Tax | usually on discounted subtotal |
Coupon fine print may use different stacking rules.
How the estimate is built
p₁ = price×(1−d₁); p₂ = p₁×(1−d₂); total = p₂×(1+tax).
Example scenario
$80 at 25% off → $60 before tax.
FAQ
Are two discounts additive?
Usually no. 25% then 10% off is less than 35% off the original.
Does tax apply before or after discount?
Most US receipts tax the discounted price; your locale may differ.
What if I only know the percent off?
A simpler percent-off page does one markdown step without tax stacking.
