Apply one or two successive discounts, see the effective discount and the price after GST.
what you pay
Final price
₹800

₹1,200
Effective discount
60.0%
50% + 20% is not 70% off — the second discount applies to the reduced price, so the real discount is 60.0%.

Discounts are everywhere — in festive sales, bulk deals and stacked offers like ‘50% + extra 20% off’. Successive discounts don't add up: each one applies to the already-reduced price.
For businesses, understanding the effective discount protects margins; for buyers, it shows the real saving.
Final price = Price × (1 − D1%) × (1 − D2%)
Discount % = (Original price − Sale price) ÷ Original price × 100.
No. The 20% applies to the already-halved price, so the effective discount is 60%.
Generally GST is charged on the transaction value after discounts shown on the invoice.
A discount comes straight out of your margin. A 20% discount on a product with a 30% margin cuts profit per unit by two-thirds.
