Calculate discounted prices, savings amount and original price from any percentage.
Quick Discount:
A discount calculator works out the final price after a percentage discount is applied, or figures out what percentage off you're actually getting if you already know the original and sale price. It's the quick math check people do while shopping online or comparing sale prices in a store, especially when the discount involves odd percentages like 15% or 37%.
Mental math on discounts gets messy fast, especially with numbers that aren't round like 10% or 50%. This tool exists so you don't have to do the multiplication in your head while standing in a checkout line or trying to compare two 'sale' prices side by side.
The math is straightforward: Final Price = Original Price × (1 − Discount% ÷ 100). So a $80 item with a 25% discount becomes $80 × 0.75 = $60, saving you $20. The reverse calculation works by comparing the difference between original and sale price as a percentage of the original, which is handy when a store advertises a sale price but doesn't clearly state the discount percentage.
Multiply the original price by (1 minus the discount as a decimal). For example, a 20% discount means multiplying by 0.8.
Yes, enter the original and sale price and it can work out the exact percentage discount applied.
Stacked discounts aren't simply added together — you'd calculate the first discount, then apply the second to the new reduced price, which this calculator can do in two steps.
It's built specifically for discounts, but the same percentage logic applies if you wanted to estimate added tax instead of a reduction.
Because the second discount applies to the already-reduced price, not the original, so 20% + 10% off doesn't equal a flat 30% off the original price.
