Frequently asked questions
How do I calculate 20% off?
Multiply the price by 0.8. For Rs 5,000 that is Rs 4,000, a saving of Rs 1,000.
Why isn't 30% + 20% equal to 50% off?
The second discount is taken from the already reduced price. 30% then 20% off leaves 56% of the price, a 44% total discount.
Is tax added after the discount?
Usually yes: sales tax is charged on the discounted price. Use the VAT / GST calculator for that step.
