How to use the discount calculator

- Type the original price of the item.
- Set the discount — use the quick buttons (10%, 20%, 25%, 50%, 70%) or type your own.
- Optionally add a GST or tax % that applies after the discount, and pick your currency.
- Read the final price and the amount saved in the result cards.
How to calculate a discount or percentage off
To find a discount, multiply the price by the discount percentage divided by 100. The formula is
amount saved = price × (discount% ÷ 100), and the
final price = price − amount saved. If a tax is added afterwards, the final price becomes
final price × (1 + tax% ÷ 100).
For example, an item priced at ₹2,000 with 25% off saves you ₹2,000 × 0.25 = ₹500, so the final price is ₹2,000 − ₹500 = ₹1,500. If the discount is a flat amount instead, you simply subtract that amount directly from the price. The calculator never lets the final price drop below zero, even if the flat discount is larger than the price.
