Frequently asked questions

How do I calculate the final price after a discount?

Multiply the original price by the discount percentage to find the amount saved, then subtract that from the original price to get the final price.

How do stacked discounts (like 20% + 10%) work?

Stacked discounts are usually applied sequentially, not added together — a 20% discount followed by an additional 10% off the reduced price equals a combined discount of 28%, not 30%. Apply this calculator twice, using the first result as the next original price.

Is GST calculated before or after the discount?

In India, GST is normally calculated on the discounted (final) sale price, not the original MRP, when the discount is shown on the invoice. Use the GST Calculator on the final price from this tool.

Is "percent off" the same as "discount"?

Yes — "percent off" and "discount percentage" describe the same calculation. This calculator uses the identical formula as the Discount Calculator, just phrased around the common "X% off" search a shopper types.

Does this include GST?

No — enter the pre-tax price to get a pre-tax discount, or the tax-inclusive price to get a tax-inclusive discount; the math is the same either way, just be consistent about which price you're using.

How Markup and Margin Turn a Cost Price Into a Selling Price

Markup adds a percentage of the cost price on top to reach a selling price, while margin works backward from the selling price itself — two different bases for the same percentage idea, each producing a different selling price from the identical cost and rate.
