Discount Calculator
Calculate the final price after a discount, the discount percentage, or the original MRP.
Discount calculator works in three modes. Mode 1 takes the original price and discount percentage to compute the final price and savings. Mode 2 takes the original and final prices to find the discount percentage. Mode 3 takes the final price and discount percentage to recover the original MRP. All three modes run instantly in the browser with no signup required.
Frequently Asked Questions
- How do I calculate 20% off a price?
- Multiply the original price by 0.20 to find the discount amount, then subtract from the original. For Rs 1,200 at 20% off: discount = Rs 240, final price = Rs 960. Enter the values in Mode 1 for an instant result.
- How do I find the original price from a sale price?
- If you know the sale price and the discount percentage, use Mode 3 of this calculator. The formula is: original price = sale price / (1 - discount% / 100). For a Rs 800 sale price at 20% off: original = 800 / 0.80 = Rs 1,000.
- How do I calculate what percentage off a price is?
- Subtract the sale price from the original, divide by the original, and multiply by 100. For a product at Rs 500 now at Rs 375: (500 - 375) / 500 × 100 = 25% off. Use Mode 2 to compute it instantly.
- What is MRP?
- MRP stands for Maximum Retail Price, the highest price at which a product can be legally sold in India. Products sold above MRP violate the Legal Metrology Act. Discounts are calculated off the MRP. A product with an MRP of Rs 200 sold at Rs 150 carries a 25% discount.
- How do I calculate GST on a discounted price?
- GST applies to the final transaction value after discount. For a Rs 1,000 product at 10% discount: final price = Rs 900. GST at 18% = Rs 900 × 0.18 = Rs 162. Total payable = Rs 1,062. Use this tool for the discounted price, then the GST Calculator for the tax amount.
What is the discount calculator?
The discount calculator solves three common pricing problems. Mode 1 takes the original price and discount percentage, then finds the final price and rupee savings. Mode 2 takes both prices and finds the discount percentage. Mode 3 takes the sale price and percentage to recover the original MRP.
All three modes run instantly in the browser. No server call is needed.
How discount percentages work
A discount percentage represents the fraction of the original price removed. At 25% off, you pay 75% of the original price. At 50% off, you pay half. The formula for the final price is: Final = Original × (1 - Discount% / 100).
Mode 1 with Rs 1,500 original at 30% off: Final = 1500 × 0.70 = Rs 1,050. Savings = Rs 450.
Mode 2 with original Rs 800 and final Rs 560: Discount% = 240 / 800 × 100 = 30%.
Mode 3 with final price Rs 700 at 30% off: Original = 700 / 0.70 = Rs 1,000.
Discount calculators in Indian retail
Flat discounts on MRP are the standard format in Indian retail, both online and offline. E-commerce sites show "X% off" relative to MRP. Flash sales reduce prices further. Bank offer pages advertise cashback as an additional percentage off the cart total.
Stacked discounts are not additive. 20% off plus 10% off does not equal 30% off. Calculate them in sequence: 20% off Rs 1,000 = Rs 800, then 10% off Rs 800 = Rs 720. The effective combined discount is 28%, not 30%.
In GST accounting, discounts reduce the taxable value when linked to a supply agreement. Discounts agreed before the sale reduce the GST base. Post-sale discounts require a credit note to adjust the tax liability.
Tips for using the discount calculator
- Use Mode 3 when a product label shows only the sale price and the discount percentage. Recover the MRP to verify the deal is genuine.
- For stacked discounts, run Mode 1 twice. First apply the larger discount to get the intermediate price. Then apply the second discount to that price.
- Flat cashback is not the same as a discount. Rs 200 cashback on a Rs 1,000 item is a 20% effective discount only if you actually redeem it. Credit into a wallet with an expiry date reduces its real value.
