How it works
How to use the Discount Calculator tool
- 1
Enter the price
The original or marked price.
- 2
Add discounts
A main discount and an optional extra discount.
- 3
See the final price
Optionally include tax or GST.
Stacked discounts don’t add up
“20% off + extra 10% off” isn’t 30% off: the second discount applies to the already reduced price, giving 28% in total. The calculator shows the real effective discount.
Limitations
We’d rather be upfront about what this tool can’t do yet:
- Assumes percentages apply in the order shown.

How do I calculate a discount by hand?
Final price = price × (1 − discount ÷ 100). For 25% off ₹1,200: 1,200 × 0.75 = ₹900.
