Hover a segment for value + share.
After the first discount: ₹3,499. Sellers stack percentages on the reduced price — this calculator does the honest multiplication.
What this calculator answers
An MRP of ₹4,999 with 30% off and a further 10% coupon lands at ₹3,149, saving ₹1,850 — an effective 37% off rather than 40%. Enter the price and both discounts to see what actually stacks.
How it is calculated
The first discount is applied to the MRP, then the extra coupon is applied to the already-reduced price. The effective discount is total savings ÷ MRP.
Discounts are treated as sequential, which is how most stacked retail offers are applied. Taxes, shipping and card-offer caps are not included.
Common questions
Why isn't a 30% plus 10% offer 40% off?
The second discount applies to the reduced price, so 10% of ₹3,499 is smaller than 10% of ₹4,999. The combined effective discount is about 37%.
Does the order of the two discounts matter?
No. Multiplying (1 − 30%) by (1 − 10%) gives the same final price whichever discount is applied first.
Can I use it for bank card offers?
Yes — put the card discount in the first box and any coupon in the second. Most card offers carry a minimum spend or a maximum discount, and that cap is not modelled here.
