Frequently asked questions

How is the sale price calculated?
Multiply the original price by (1 − percent off ÷ 100). For example, a $2,000 item at 25% off is 2000 × (1 − 0.25) = $1,500. Choose the "Original − % off" mode and enter the price and the discount percentage.
How do I find the percent off from two prices?
Switch to "Find % off" mode and enter the original price and the sale price. The calculator works out ((original − sale) ÷ original) × 100 for you — so a $2,000 item marked down to $1,500 is 25% off.
Can I stack two discounts, like 20% off plus an extra 10%?
Apply them one after another rather than adding the percentages — 20% off followed by 10% off is not the same as 30% off. Run the first discount through the calculator, then feed the resulting sale price back in as the new original price for the second discount.
Which currencies can I use?
Toggle between $ and ₹ with the currency switch above the inputs. Every result updates to match, using the digit grouping each currency normally uses.
Is my data stored or uploaded anywhere?
No. Every calculation runs locally in your browser and your last inputs are saved only to this browser's local storage for convenience — nothing is ever sent to a server.
Is the discount calculator really free?
Yes — nothing to pay, nothing to register for, no watermark. The only revenue here is one modest ad slot on the page.
Do I need to create an account?
No. There's no account system at all. Open the page and start typing.
