Percent Off Calculator

A percent off calculator tells you the sale price and the rupees you save when a percentage discount is taken off an original price. It is the tool you reach for the moment you see "X% off" — on a Myntra sale banner, a restaurant coupon, an electronics festival offer, or a clearance rack — and want to know the real price before you commit. Type the original price and the percentage, and you instantly get the amount off, the final price, and the share of the original you still pay.

This page also works in reverse. If you already know what you paid and the discount that was applied, the reverse calculator below recovers the original (pre-discount) price — useful for checking whether an "original" price quoted in an ad is genuine, or for reconstructing a list price from a receipt.

What it does and who it is for

It is made for Indian shoppers comparing deals, freelancers and shop owners offering a discount to customers, and anyone who wants the maths done correctly without reaching for a phone calculator. Beyond the headline result, the page shows a quick-reference strip of the same discount applied to common price points (₹50 to ₹2,000) and a visual bar splitting what you pay from what you save, so the deal is easy to judge at a glance.

How it works (the formula)

"Percent off" means the percentage is subtracted from the price. The amount removed is the discount rate times the original; the final price is what remains:

Amount Off = Original × (Percent ÷ 100)

Sale Price = Original − Amount Off = Original × (1 − Percent ÷ 100)

The compact form is fastest to use mentally: 30% off means you pay 70%, so multiply by 0.70; 15% off means you pay 85%, so multiply by 0.85. The calculator also reports "You Pay %" so the surviving share of the price is obvious.

Reverse calculation

To find the original price from what you paid, divide by the paying fraction rather than adding the percentage back:

Original = Sale Price ÷ (1 − Percent ÷ 100)

If you paid ₹1,275 after a 15% discount, the original was ₹1,275 ÷ 0.85 = ₹1,500 — not ₹1,275 × 1.15, which would wrongly give ₹1,466.25.

A worked example in rupees

A pair of running shoes is listed at ₹3,500 with 40% off. The amount off is ₹3,500 × (40 ÷ 100) = ₹3,500 × 0.40 = ₹1,400. The sale price is ₹3,500 − ₹1,400 = ₹2,100, which is 60% of the original. The one-step check: ₹3,500 × 0.60 = ₹2,100. So you save ₹1,400 and pay ₹2,100.

The same 40% off at different price points:

Handy tips

• The 10% anchor: find 10% by shifting the decimal one place, then scale. 10% of ₹3,500 is ₹350, so 40% is ₹1,400 and 5% is ₹175.
• Use the reverse tool to spot fake MRPs: if a "70% off" sale price implies an original far above what the item normally sells for, the list price may be inflated.
• Coupons on top of sale prices: an extra coupon usually applies to the already-discounted price, so combine them as a stacked discount, not a simple sum.

Common mistakes to avoid

• Adding percentages: "extra 10% off" on a 30% sale is not 40% off. It is 1 − (0.70 × 0.90) = 37% off, because the second cut applies to the reduced price.
• Reversing by adding back: recovering the original means dividing by (1 − percent), never multiplying by (1 + percent).
• Assuming percent off equals percent saved on tax: a discount lowers the taxable base on a pre-tax price, but on most GST-inclusive Indian tags the percentage simply applies to the displayed amount.
