Find sale price after discount, calculate discount percentage, or work out the original price from a sale price.
How discount calculations work
Three common scenarios when shopping — this calculator handles all of them.
Frequently asked questions
How do I calculate 20% off a price?
Multiply the original price by 0.20 to get the discount amount, then subtract it from the original. For example, 20% off ₹1,500 = ₹300 discount, so you pay ₹1,200. Or simply multiply by 0.80 (i.e., 1 − 0.20).
What is the difference between discount and discount percentage?
Discount is the absolute amount saved in rupees. Discount percentage is the savings expressed as a proportion of the original price. A ₹200 discount on a ₹1,000 item is a 20% discount.
How do I find the original price if I only know the sale price and discount?
Divide the sale price by (1 − discount%/100). If something costs ₹600 after a 25% discount, the original price was ₹600 ÷ 0.75 = ₹800.
Are the quick discount buttons (5%–50%) Indian-standard discounts?
Yes, these cover the most common retail discount tiers in India — from small sale discounts (5–10%) to clearance sale discounts (40–50%). Online platforms like Flipkart and Amazon India frequently use these values.
Does this calculator handle GST on discounts?
No, this calculator works with pre-tax or post-tax prices as you enter them. If a product is discounted and then GST is applied, enter the post-discount price in the GST calculator separately. The MRP on Indian products is always GST-inclusive.
