Discount Calculator

A discount is a reduction in the standard retail or list price of a product or service, typically expressed as a percentage off the original price or a fixed monetary deduction.

Multiply the original price by the discount percentage and divide by 100: Discount Amount = Original Price × (Discount % ÷ 100). The final sale price is Original Price minus Discount Amount.

The standard formulas are: Discount Amount = Original Price × (Discount % ÷ 100), and Final Price = Original Price × (1 − Discount % ÷ 100).

Subtract the discount percentage from 100%, convert it to a decimal, and multiply by the original price. For a 20% discount on ₹10,000: ₹10,000 × 0.80 = ₹8,000.

Your savings equal the discount amount: Savings = Original Price − Final Sale Price. For a 20% discount on ₹10,000, you save ₹2,000.

Divide the original price by 10. For ₹1,000, 10% off is ₹100, making the final price ₹900.

Divide the original price by 5 (or multiply by 0.20). For ₹1,000, 20% off is ₹200, making the final price ₹800.

Divide the original price by 4 (or multiply by 0.25). For ₹1,000, 25% off is ₹250, making the final price ₹750.

Multiply the original price by 0.30. For ₹1,000, 30% off is ₹300, making the final price ₹700.

Divide the original price by 2 (half price). For ₹1,000, 50% off is ₹500, making the final price ₹500.

Divide the sale price by (1 − Discount % ÷ 100). For an item sold at ₹8,000 after a 20% discount: ₹8,000 ÷ 0.80 = ₹10,000 original price.

Divide the savings by the original price and multiply by 100: Discount % = [(Original Price − Sale Price) ÷ Original Price] × 100.

A successive (or sequential) discount applies multiple discounts one after another to the remaining balance, rather than simply adding the percentages together.

No. Two sequential 10% discounts equal an effective discount of 19%. On ₹100: first −10% = ₹90, then −10% of ₹90 = ₹81 (₹19 total discount, not ₹20).

Under commercial practice and GST rules, trade discounts reflected on the invoice reduce the taxable value first, so GST is levied only on the net discounted price.

In commercial invoices, GST is almost always calculated after applying trade discounts. However, if a post-sale rebate is issued separately, tax was initially assessed before discount.

Calculate the final prices for both offers on the same original price. The difference between the two final prices represents your extra savings.

At 10%: save ₹100 (pay ₹900). At 20%: save ₹200 (pay ₹800). At 30%: save ₹300 (pay ₹700). At 50%: save ₹500 (pay ₹500).

At 15%: save ₹1,500 (pay ₹8,500). At 20%: save ₹2,000 (pay ₹8,000). At 25%: save ₹2,500 (pay ₹7,500). At 40%: save ₹4,000 (pay ₹6,000).
