About Discount Calculations

Sale Price

Multiply the original price by (1 − discount/100). A 20% discount on ₹1000 = ₹1000 × 0.80 = ₹800.

Discount %

Divide the saved amount by the original price and multiply by 100. Saved ₹200 from ₹1000 = 20%.

Successive Discounts

Two discounts of 10% and 5% are NOT 15%. The combined effect is 1 − (0.9 × 0.95) = 14.5% — always less than the sum.

Tax After Discount

GST/VAT is usually calculated on the discounted price, not the original price. This tool applies tax after all discounts for accuracy.
