About the Discount Calculator
Retailers know that "20% + 10% off" sounds like 30% — and it is not. Successive discounts multiply: ₹1,000 loses 20% to become ₹800, then loses 10% of 800 to land at ₹720. The effective discount is 28%, and that two-point gap is exactly where marketing hopes you stop thinking. This calculator applies each discount in sequence and names the true effective percentage.
For single discounts the tool shows the sale price and absolute savings. For stacked deals — store sale plus bank offer plus coupon code — it walks through each step so you can see precisely where the price lands. The effective figure lets you compare a confusing 15%+10% bundle against a flat 22% competitor price in one glance.
Everything computes locally as you type. No prices, coupons, or shopping data touch a server.
There is also a psychology worth knowing as a buyer: retailers frame discounts against reference prices that may be selectively raised before sale events. The defence is price history — check what the item actually sold for over recent weeks, then apply this tool\’s effective-discount math to the real anchor, not the inflated one. Arithmetic cannot fix a dishonest baseline, but it will at least stop a stacked-coupon offer from feeling better than its flat equivalent.

Who uses the Discount Calculator?
- Festive-season shopping: comparing bank-offer stacks against flat discounts.

- Reviewers and deal-hunters exposing inflated "was" prices honestly.
Tips and best practices
- Always ask for the effective single percentage when a deal lists multiple offers — then compare against flat discounts like-for-like.
- The order of stacked discounts does not change the final price (multiplication commutes), but store systems may apply caps differently; check terms.
- A rupee-off coupon and a percent-off coupon interact: on small carts, flat ₹-off often beats a small percentage deal; on large carts, the reverse.
- Beware anchor inflation. If the "original" price is invented, even a real 40% discount is not a bargain — track typical street prices instead.
- GST is computed on the discounted sale value for most invoice-level discounts, so your final bill is discount first, tax after.
Frequently asked questions
Sale price = original − (original × discount ÷ 100). For example, ₹2,000 at 25% off saves ₹500, giving ₹1,500.
The second discount applies to the already-reduced price: ₹1,000 → 20% off → ₹800 → 10% off → ₹720, an effective 28% total discount, not 30%.
Yes — put the store discount in the first field and the coupon in the second. They apply in that order, which matches standard checkout behaviour.
For discounts written on the invoice, GST is charged on the net amount after the discount. Use the GST Calculator on the discounted price to add tax correctly.
The single flat discount that would produce the same final price as a sequence of discounts — the honest number for comparing deals.
