    Discount formulas

    To findFormulaExample
    Amount offprice × discount ÷ 100₹2,000 × 25 ÷ 100 = ₹500
    Sale priceprice × (1 − discount ÷ 100)₹2,000 × 0.75 = ₹1,500
    % off(original − sale) ÷ original × 100(₹2,000 − ₹1,500) ÷ ₹2,000 × 100 = 25%
    Original pricesale ÷ (1 − discount ÷ 100)₹1,500 ÷ 0.75 = ₹2,000
    Two discounts1 − (1 − a)(1 − b)20% + 10% = 1 − 0.8 × 0.9 = 28%

    Spotting the better deal

    • Percent vs flat amount: “₹500 off” beats “20% off” only when the price is below ₹2,500 – enter both as separate discounts to compare.
    • “Up to” offers: a 50% discount capped at ₹100 is only worth 50% on items up to ₹200.
    • Buy 2 get 1 free is the same as 33.33% off each item when all three cost the same.
    • Check the price before the sale: a big percentage off an inflated “original” price may not be a real saving.

    Frequently asked questions

    How do I calculate a discount?

    Multiply the price by the discount percentage and divide by 100 to get the amount off, then subtract it from the price. For example, 20% off ₹2,499 is ₹499.80 off, so you pay ₹1,999.20. The calculator does this instantly and shows each step.

    Is 20% + 10% off the same as 30% off?

    No. Stacked discounts apply one after another, so the second discount is taken from the already-reduced price. 20% then 10% off equals 28% off in total, not 30%.

    How do “up to” discounts work?

    Offers like “50% off up to ₹100” give the percentage discount but never more than the limit. Enter 50 as the discount and 100 as the maximum – the receipt marks the discount as capped when the limit applies.

    How do I find the percentage off between two prices?

    Open “Find % off”, enter the original price and the price you pay. The calculator shows the discount percentage and how much you save. If the new price is higher, it shows the increase.

    How do I find the original price before a discount?

    Open “Original price”, enter the sale price and the discount. The original price is the sale price divided by (1 − discount ÷ 100). For example, ₹800 after 20% off was originally ₹1,000.

    Should tax be added before or after the discount?

    Usually the discount comes off first and tax such as GST or VAT is charged on the reduced price. Choose “Added after discount” for prices shown without tax, or “Included in price” for prices that already include tax, as in most Indian and European shops.

    Does the order of discounts matter?

    For percentages alone, no – 20% then 10% gives the same result as 10% then 20%. When you mix a percentage with a flat amount, or a capped discount, the order changes the final price. The calculator applies them from top to bottom.

    Is the discount calculator free?

    Yes, completely free with no sign-up. Everything is calculated in your browser and nothing is saved.
