Work out a discount
Three questions, one page
Most of the time you want the obvious one: a jacket at ₹2,499 with 30% off comes to ₹1,749. But two other questions come up just as often. A shop says a shirt is down from ₹1,800 to ₹1,199 — what discount is that, really? Or you paid ₹1,749 in a 30% off sale and want to know what the label said. Switch the mode at the top and the same form answers all three.
Stacked discounts do not add up
An extra 10% off an item already reduced by 40% is not 50% off. The second discount applies to the already-reduced price, so ₹1,000 becomes ₹600 and then ₹540 — a 46% discount overall, not 50%. To work out a stack, run the calculator twice, using the first result as the second original price.
Discount off what, exactly
A percentage means nothing without the price it is taken from. A steep discount off an inflated MRP can leave you paying more than a modest discount somewhere honest, which is the whole mechanism behind sale pricing. Compare the final rupee figure between sellers, not the percentage on the sticker.
Frequently asked questions
How do I calculate a 30% discount?
Multiply the price by 0.30 to get the saving, then subtract it. On ₹2,499 that is ₹749.70 off, leaving ₹1,749.30. The first mode on this page does it for you.
How do I work out what percentage discount I got?
Subtract what you paid from the original price, divide by the original price, and multiply by 100. Use the second mode and type both prices.
Can I stack two discounts?
You can apply them one after another, but they do not add. A 40% discount followed by another 10% off the reduced price works out to 46% overall, not 50%.
Is the discount calculated before or after GST?
Ordinarily a discount applies to the pre-tax price and GST is charged on what remains, so the tax falls too. A price marked as GST-inclusive already has the tax inside it, and a discount off that figure reduces both parts together.
What does the original price mode do?
It works backwards. If you know what you paid and the discount that was applied, it recovers the price before the discount — useful for checking a receipt or a claimed saving.
