Find answers to common questions about this calculator below.
How to calculate discount percentage?
Discount amount = Original Price × (Discount%/100). Final Price = Original Price - Discount Amount. For example, 20% off ₹1,000 = ₹200 discount, final price ₹800.
How to calculate original price before discount?
If you know the final price and discount percentage: Original Price = Final Price / (1 - Discount%/100). For example, if final price is ₹800 after 20% off: Original = 800/0.8 = ₹1,000.
Discount percentage?
(Discount / Original) × 100. ₹2,000 to ₹1,600 = 20%.
BOGO effective discount?
Buy 1 Get 1: Free item / Total. Both ₹500 = 50% discount.
Discount vs GST?
Discount on MRP, GST on discounted value. ₹1,000 at 20% off + 18% GST = ₹944.
20% off calculation?
Pay = Price × 0.80. ₹1,000 item = ₹800.
Tiered discount?
Applied sequentially. 20% + 10% on ₹1,000 = 28% total (not 30%).
