About this tool
A sale sign gives you a percentage and leaves the useful number for you to work out while standing in the aisle. Forty per cent off ₹2,349 is not a sum most people do quickly or correctly. Type the price, type the percentage, and you get both the amount you will pay and the amount you are saving, which is the figure that actually answers whether the deal is worth it.
Both numbers come out to two decimal places, because retail prices are full of 99s and the paise are real. They are also grouped the Indian way — the final price on something expensive reads as ₹12,45,000.00, so you can see at a glance whether it is lakhs or thousands without counting zeros.
One thing to watch: stacked discounts do not add up. An offer of 20% off followed by a further 10% off is 28% off in total, not 30%, because the second cut applies to the already-reduced price. Run the tool twice, feeding the first result back in, and you get the right answer.
How to use this tool
- Enter the original price. The price before the discount, in rupees. Paise are fine. Anything from 0 up to one lakh crore is accepted.
- Enter the discount percentage. Between 0 and 100. It starts at 20. Anything outside that range gets rejected with a message telling you the bounds.
- Read both figures. The final price and the amount saved, each to two decimal places and grouped Indian-style — ₹1,24,999.50, not ₹124999.5.
What this tool does not do
- No GST, cess or any other tax is applied or removed.
- It does not stack two discounts for you, and it does not handle “buy two get one free” style offers.
- It does not work backwards — you cannot give it a sale price and get the original.
- There is no currency conversion, and no rounding rule for a shop that rounds to the nearest rupee.
Common questions
Does the answer include GST?
No. The tool does one subtraction on the number you typed. If the price on the tag already includes tax then so does the final price it gives you; if tax gets added at the counter, this figure is before that.
How do I handle “extra 10% off on the discounted price”?
Run it twice. Take the final price from the first run, put it back in as the original price, and apply the second discount to that. Two discounts of 20% and 10% come to 28% off, not 30%.
Can I enter a discount above 100%?
No. The field is capped at 100, which is the point where the price reaches zero. Beyond that the shop would be paying you.
Why two decimal places?
Because 15% off ₹899 is ₹134.85, and rounding that away hides the paise that show up on the bill. Both figures are given to the same precision so they add back to the original price.
Can I use it for a currency other than rupees?
The arithmetic is identical, but the labels say rupees and there is no conversion. Read the ₹ as whatever you are working in.
