Discount Calculator
Find the sale price, the discount percentage, the original price, or the true effect of stacked discounts — instantly.
About this calculator
This free discount calculator handles every common sale-price question in four modes. Find the final price after a discount and see exactly how much you save, work out what percentage off you are actually getting from an original and sale price, recover the original price from a discounted one, and calculate stacked (double) discounts that apply one after another.
It is perfect for shoppers comparing deals, sellers setting sale prices, and anyone checking whether an advertised offer is as good as it sounds. The stacked-discount mode is especially useful because two successive discounts never simply add up — the calculator shows the true effective discount. Everything runs locally in your browser with instant results and nothing uploaded.

Frequently asked questions
Final price = original price × (1 − discount% ÷ 100). For example, ₹2,000 with 20% off becomes ₹1,600, saving you ₹400.
Discount% = ((original − sale) ÷ original) × 100. Enter the original and sale prices in the “Discount %” mode to see it instantly.
Original = sale price ÷ (1 − discount% ÷ 100). Use the “Original price” mode when you know the sale price and the discount.
No. Stacked discounts apply one after another, so 20% then 10% off ₹100 gives ₹72 — an effective 28% discount, not 30%, because the second discount applies to the already-reduced price.
