This discount calculator shows the final price after a discount, how much you save and the real effective discount when two offers stack. You can also add GST on the discounted price, which is how most Indian bills are worked out. It is useful for sale shopping, festive offers and pricing your own products.
What is a Discount Calculator?
A discount is a reduction from the listed price, usually given as a percentage. A 40% discount on ₹2,999 means you pay 60% of the price. When a second offer applies, such as a coupon or a bank card discount, it is usually calculated on the already reduced price, not on the MRP.
A discount calculator does the arithmetic for you and shows the effective discount, which is the true total percentage you save. This matters during sales, when “40% + 10% off” sounds like 50% but is actually 46%.
How does the Discount Calculator work?
The calculator multiplies the original price by (1 − discount ÷ 100). If you enter an extra discount, it repeats the step on the new price. The effective discount is your total saving divided by the original price.
If you choose a GST rate, the tax is added on the final discounted value. Under GST rules, a discount shown on the invoice at the time of sale reduces the taxable value, so GST is charged on the lower price.
How to use the Discount Calculator step by step
- Enter the original price or MRP.
- Enter the main discount percentage.
- Add an extra discount if a coupon or card offer applies.
- Choose whether to add GST, or leave it as included.
- See the price you pay, the amount saved and the effective discount.
- Copy the result to share with family or a customer.
Discount Calculator example with real numbers
A pair of shoes has an MRP of ₹2,999. The store gives 40% off, and your bank card gives an extra 10% off the sale price.
| Example input | Value |
|---|---|
| Original price (MRP) | ₹2,999 |
| Discount | 40% |
| Extra discount (optional) | 10% |
| GST on discounted price | Price already includes GST |
| Example output | Value |
|---|---|
| Price you pay | ₹1,619.46 |
| Original price | ₹2,999.00 |
| After first discount | ₹1,799.40 |
| After extra discount | ₹1,619.46 |
| You save | ₹1,379.54 |
| Effective discount | 46.00% |
The discount calculator applies 40% first and then 10% on the reduced price, so you pay ₹1,619.46. Your total saving is ₹1,379.54, an effective discount of 46.00%, not 50%.

Limitations of this Discount Calculator

Discount Calculator FAQs
How do I calculate a discount percentage?
Subtract the sale price from the original price, divide by the original price and multiply by 100. If a ₹2,000 item sells for ₹1,500, the discount is 500 ÷ 2,000 × 100 = 25%.
How do successive discounts work?
Each discount applies to the price left after the previous one. 40% and then 10% off works out to 46% off in total, because the 10% is taken from 60% of the price.
Is GST charged before or after discount?
Under GST law, a discount shown on the invoice at the time of supply reduces the taxable value, so GST is charged on the discounted price.
How do I find the original price after a discount?
Divide the sale price by (1 − discount ÷ 100). If you paid ₹1,800 after 25% off, the original price was 1,800 ÷ 0.75 = ₹2,400.
Which is better: 50% off or 30% + 30% off?
50% off is better. 30% followed by 30% gives 51% of the price, which is 49% off.
What are the current GST rates in India?
Since the GST rate rationalisation of September 2025, most goods and services fall under 5% or 18%, with 40% for a small list of luxury and sin goods. Some items are exempt.
