Frequently Asked Questions

1

How do I calculate discount?

Discount Amount = Original Price × (Discount % / 100). Final Price = Original Price - Discount Amount. For example, 20% off ₹1000 = ₹200 discount, final price ₹800.

2

How does double discount work?

In double discount (e.g., 30% + 20%), the first discount is applied to the original price, then the second discount is applied to the already-discounted price. So 30%+20% off ₹1000 = ₹1000 → ₹700 → ₹560, which is NOT 50% off.

3

Is tax applied before or after discount?

Tax (GST) is typically applied after the discount. So first the discount reduces the price, then tax is calculated on the discounted amount.

4

What is reverse discount calculation?

Reverse calculation finds the original price when you know the final price and discount percentage. Formula: Original Price = Final Price / (1 - Discount/100).
