Successive discounts are applied one after another, not added directly. A 20% + 5% discount equals 24% effective discount, not 25%.

Quick answer

Double discounts are not additive. A 20% and 10% stacked offer gives 28% effective discount, not 30%.

A discount calculator helps buyers and sellers quickly determine final sale price after markdowns. It is useful for ecommerce offers, festive sales, bulk deals, and invoice negotiations where multiple discount layers are common.

What is this calculator?

This tool calculates first discount amount, optional second discount, final payable price, total rupee savings, and effective discount percentage. It removes confusion around stacked offers and marketing labels.

Formula

After first discount = Original Price x (1 - d1/100)
After second discount = After first discount x (1 - d2/100)

Total savings = Original Price - Final Price
Effective discount % = (Total savings / Original Price) x 100

Example

Original price Rs 10,000. First discount 20%. Second discount 5%. After first discount = Rs 8,000. After second discount = Rs 7,600. Total savings = Rs 2,400. Effective discount = 24%, not 25%.

Another example

For a product priced at Rs 4,999 with 35% festive offer, final price becomes about Rs 3,249. Add coupon discount after this to see true checkout value instead of relying on advertised percentages.

Frequently Asked Questions

Why is 20% + 10% not equal to 30%?
Because the second discount is applied on reduced price after the first discount, so total effective discount is lower than direct addition.
Can I use this for GST invoice pricing?
Yes for base discount computation. Add GST separately to get final invoice amount.
Is effective discount always lower than sum of discounts?
Yes for positive stacked percentage discounts, unless the second discount is zero.
Does this include cashback offers?
No. Cashback is usually post-payment and may have terms; treat it separately from invoice discount.
Can sellers use this for margin planning?
Yes. It quickly shows impact of discount structure before confirming client price.

Discount outputs are arithmetic estimates. Final checkout may change with taxes, coupons, shipping, platform fees, and minimum-order rules.
