How It Works

The calculator multiplies the original price by the share that remains after the discount to find the sale price, then subtracts that from the original to show your savings. When you add a second discount it is applied to the already-reduced price, not added to the first — so "25% off plus an extra 10%" is less than 35% off in total. The calculator shows the true combined discount, which is the figure that actually matters at checkout.

Formula

Sale Price = Original × (1 − Discount%)
Savings = Original − Sale Price

How do stacked discounts work?

Stacked discounts apply one after another, not added together. "25% off plus extra 10%" on $80 = $80 × 0.75 × 0.90 = $54, a total of 32.5% off (not 35%).
