Calculate Discount Amount & Final Price Online

How This Discount Calculator Works

This calculator helps you understand how a discount changes the amount payable by a customer. You can calculate a percentage discount, flat rupee discount, GST amount and final invoice value.

For GST-exclusive prices

The discount is reduced from the original taxable value first. GST is then calculated on the discounted taxable value.

For GST-inclusive prices

The calculator treats the entered price as a GST-inclusive price. It applies the discount to the GST-inclusive price, then reverse-calculates the taxable value and GST component.

Useful For

• Retail stores calculating final customer billing price.
• Online sellers showing offer price after discount and GST.
• Freelancers issuing discounted service invoices.
• Small businesses estimating taxable value after discount.
• Customers checking actual saving before making a purchase.
