In plain English — what does this do?
🎉 A discount means something costs LESS than normal — like a toy that was ₹500 but is now 20% off. This tool tells you the new lower price so you know exactly how much you save!
A discount calculator finds the final price after one or more percentage discounts are applied to an original price. It also calculates the total amount saved and the effective percentage off. An optional tax field allows you to see the final price inclusive of sales tax or GST after the discount has been applied.

What is Discount Calculator?
A discount calculator finds the final price after one or more percentage discounts are applied to an original price. It also calculates the total amount saved and the effective percentage off. An optional tax field allows you to see the final price inclusive of sales tax or GST after the discount has been applied.

❓ Common questions
- Are two stacked discounts the same as their sum?
- No. A 30% discount followed by a 10% discount gives an effective 37% off, not 40%. Each discount is applied to the already-reduced price, so they multiply rather than add.
- How do I find the original price if I only know the discounted price?
- Divide the discounted price by (1 - discount rate). For example, if the sale price is $70 after a 30% discount, the original price is 70 / 0.70 = $100.
- Does the tax apply before or after the discount?
- In this calculator, tax is applied after all discounts. This reflects most retail scenarios where sales tax is calculated on the final selling price, not the original price.
- What does effective percentage off mean?
- When two discounts are stacked, the effective percentage off is the actual total reduction from the original price. It is always less than the sum of the two individual percentages because the second discount is calculated on an already-reduced amount.
- Can I use this for calculating markup instead of discount?
- Not directly. This calculator is designed for discounts (price reductions). For markup calculations — adding a percentage to a cost price to get a selling price — a separate percentage or markup calculator would be more appropriate.
