About the discount calculator
This calculator finds the sale price and amount saved on any discounted item, from a simple original price and discount percentage. It's built for the everyday moment of standing in front of a "25% off" sign, or checking whether a coupon code actually delivers the savings it promises, without doing the percentage math in your head.
The formula is simple: the amount saved equals the original price multiplied by the discount percentage. A $100 item at 20% off saves you $20. The sale price is then just the original price minus that savings β in this example, $80. The calculator handles both numbers at once, so you can see exactly what you're paying and exactly what you're saving side by side.
Percentage discounts can be deceptively tricky to compare at a glance, especially with larger numbers or odd percentages like 15% or 35%. A $75 item at 30% off ($52.50) might actually be a better deal than a $60 item at 15% off ($51), depending on what you actually need β this calculator makes those exact dollar comparisons instant instead of requiring mental math or a physical calculator.
It's also useful for reverse-checking a store's advertised savings. If a tag says "was $200, now $150," you can plug in $200 and try different discount percentages until the sale price matches $150, which tells you the actual discount rate being applied β useful for comparing sales across different stores or verifying an in-store discount was applied correctly at checkout.
Keep in mind that this calculator handles a single, straightforward discount. It doesn't account for sales tax (which is usually applied after the discount), stacked or sequential discounts (like an additional 10% off already-reduced clearance items), or store credit and rewards that effectively change the final price further.

Discount calculator questions
How sale prices and discounts are calculated.
How do I calculate a discount?
Multiply the original price by the discount percentage (as a decimal) to find the amount saved, then subtract that from the original price to get the sale price. For example, $100 at 20% off saves $20, for a sale price of $80.
How do I find the sale price directly?
Multiply the original price by (1 minus the discount as a decimal). At 20% off, that's the original price times 0.8.
Does this include sales tax?
No β this calculator only applies the discount. Sales tax is typically calculated on the discounted sale price afterward, so add tax separately based on your local rate.
How do stacked or sequential discounts work?
Stacked discounts are applied one after another, not added together. A 20% discount followed by an additional 10% off isn't 30% off total β it's actually about 28% off, since the second discount applies to the already-reduced price. Run this calculator twice, using the first sale price as the second calculation's original price.
How can I figure out what discount percentage a sale price represents?
If you know the original price and the sale price, subtract the sale price from the original, divide by the original price, then multiply by 100. You can also try different discount percentages here until the sale price matches what you saw advertised.
Why do stores show a percentage instead of a dollar amount?
Percentages scale automatically with price, making it easy to advertise one discount rate across a wide range of items with different prices, while still communicating meaningful savings.
Is a bigger percentage discount always the better deal?
Not necessarily β it depends on the original price. A 30% discount on a cheaper item can save fewer dollars than a 15% discount on a more expensive one. Compare the actual sale prices and amounts saved, not just the percentages.
