Discount Calculator

Scope and assumptions

Sequential discounts: price × (1 − first rate) × (1 − second rate). For example 20% then 10% means 28% off. Tax and shipping are not added.

Discount Calculator: Sequential Discounts and Final Price Guide

A discount calculator finds the final price after one or two sequential reductions. Expressions like 20 percent plus 10 percent multiply rather than add. The tool runs entirely in your browser. Results are for information only; check checkout conditions.

What list price gives 800 after a 30% discount?

The list price is 1,142.86 and the discount is 342.86. The required markup over the target is about 42.86%. Adding only 30% to 800 gives 1,040; a 30% discount on that leaves 728.

800 / (1 - 30/100) = 1142.857142…

Do successive 20% and 10% discounts equal 30%?

No. A 20% discount on 1,000 leaves 800; the next 10% applies to that 800, leaving 720. Total savings are 280 and the effective discount is 28%.

1000 × (1 - 20/100) × (1 - 10/100) = 720
