Calculate sale prices, discounts, and percentage off deals
What is the Discount Calculator?
The discount works like this: it applies one or two sequential discounts, shows the final price, the absolute saving, and what the effective single discount is. Everything happens on your device - the input never leaves your tab unless the tool clearly states it performs a server-side lookup.

Enter the values the calculator asks for.
Double-check the unit or period next to each field (per month vs per year, cm vs m).

Frequently asked questions
Why do 25% + 10% not equal 35%?
The second discount applies to the already-reduced price: 0.75 × 0.90 = 0.675, so you keep 67.5% - a 32.5% total cut.
What is a good effective discount threshold?
Retail markups are often 50-100%, so 30-40% off can still be profitable for the seller - compare against genuine reference prices.
How are two stacked discounts combined?
Sequentially: the second discount applies to the already-reduced price. 25% then 10% is 0.75 x 0.90 = 32.5% off, not 35% - the tool shows this effective rate explicitly.
Can I find the original price from a sale price?
Enter the sale price as the current value and the discount percentage - the original figure and the absolute saving are both displayed for reverse checks.
