Discount Percentage Calculator
Calculate sale price, savings and effective discount instantly.
Enter the original price and the percentage off to see the final price and the money saved. A second field lets you stack another discount — an extra 10% on an already reduced price — and shows the effective discount the two add up to.

How a discount percentage is calculated
The sale price is the original price multiplied by (100 − discount) ÷ 100. A 20% discount on ₹2,499 gives ₹2,499 × 0.80 = ₹1,999.20, and the saving is the difference, ₹499.80.
Stacked discounts do not simply add up. 20% followed by another 10% is applied to the already reduced price, so the effective discount is 28%, not 30%. The calculator shows that effective figure so you can compare offers honestly.
Discount, profit and margin are different questions
A discount tells you what the customer pays. It does not tell you what you keep. Once you know the sale price, the profit calculator works out earnings at that price after cost, and the margin calculator works backwards from a target margin to the price you need.
What to do next
- check what you still earn at the sale price — enter cost and the discounted price to see profit per unit
- work backwards from a target margin — find the price a discount can safely fall to
- add or remove GST on the discounted amount — get the tax-inclusive figure a customer actually pays
