More than just percent off.
Most discount calculators only take a percentage off. This one runs the numbers in both directions, so you can start from whatever you already know.
Percentage off
The classic. Take 20% off a price and see the sale price and the amount saved.
Amount off
Knock a flat sum off a price and see what percentage that works out to.
Find the discount %
Enter the original and the sale price to reveal the discount percentage between them.
Find the original price
Know the sale price and the discount? Work back to what it cost before the offer.
Stack two discounts
Apply one discount, then another on top, and see the true combined rate. It is less than adding them up.
How the discount maths works.
The formulas behind each mode, with a worked example. The maths is the same in any currency.
Percentage off
Discount = Price × Rate ÷ 100
Sale price = Price - Discount
Example: ₹2,000 at 20% off is ₹400 saved, so you pay ₹1,600.
Find the discount %
Rate = (Price - Sale price) ÷ Price × 100
Example: A drop from ₹2,000 to ₹1,600 is a ₹400 saving, or 20% off.
Find the original price
Price = Sale price ÷ (1 - Rate ÷ 100)
Example: ₹1,600 after 20% off means the original price was ₹2,000.
Stack two discounts
Sale = Price × (1 - R1 ÷ 100) × (1 - R2 ÷ 100)
Example: 20% off then 10% off is a 28% discount overall, not 30%.
Discounts that run themselves.
This tool is great for a one-off number. But if you run offers across a catalogue, apply discounts on every invoice line, and need tax and totals to reconcile cleanly, you want that built into your billing. That is the kind of ERP, billing and CRM software we build at Techliphant, shaped around how your business actually works.

Common discount questions.
It's a free online tool that works out a discount on any price. You enter the price and the discount, and it shows the sale price, how much you save, and the discount percentage. It works in reverse too, so you can find the discount percentage between two prices or the original price before an offer.
Multiply the price by the discount rate and divide by 100 to get the amount off, then subtract that from the price. So Discount = Price × Rate ÷ 100. For example, ₹2,000 at 20% off is ₹400 saved, and the sale price is ₹1,600.
Multiply the price by one minus the rate as a decimal: Sale price = Price × (1 - Rate ÷ 100). A ₹2,000 item at 20% off comes to ₹2,000 × 0.8, which is ₹1,600.
Take the original price, subtract the sale price, divide by the original price, and multiply by 100. So Rate = (Price - Sale price) ÷ Price × 100. A drop from ₹2,000 to ₹1,600 is a ₹400 saving, which is 20% off. Set the tool to "Find the discount %" and it does this for you.
Divide the sale price by one minus the rate as a decimal: Price = Sale price ÷ (1 - Rate ÷ 100). If something cost ₹1,600 after 20% off, the original price was ₹1,600 ÷ 0.8, which is ₹2,000.
No, it comes to 28% off, not 30%. The second discount applies to the already reduced price, not the original. So ₹2,000 drops to ₹1,600 after 20%, then to ₹1,440 after another 10%. That is ₹560 off ₹2,000, which is 28%. Use the "Stack two discounts" option to see the true combined rate.
A discount lowers a selling price for the buyer. A markup is how much you add to your cost to set a price, and margin is the profit as a share of the selling price. They answer different questions, so a 20% discount and a 20% markup are not the same amount.
Apply the discount first to get the net price, then add the tax on that lower figure. On a proper invoice the discount is taken off before tax is worked out. For the tax step, our free GST and VAT calculators handle the rest.
Yes on both. It is free, there is no sign-up, and it runs entirely in your browser. Nothing you type is sent anywhere or saved, so your numbers stay on your own device.
It is great for a quick discount on a quote, a bill or a price check. For running offers across a catalogue, applying discounts on every invoice line, and keeping tax and totals reconciled, you want billing or ERP software that does it for you. That is the kind of system we build at Techliphant.
Private by design: this calculator runs entirely in your browser, so nothing you type is uploaded or stored. It is provided free for quick estimates and educational use. For invoices, receipts and contracts, confirm the final figures against your own records or accounting software.
