A GST Calculator is a free online tool that helps you calculate Goods and Services Tax on a product or service. By entering the original price and GST rate, you can find the GST amount and the final price including tax. For example, if a product costs ₹1,000 before GST and the applicable rate is 18%, the GST amount is ₹180 and the total price becomes ₹1,180. This GST Calculator Online also helps you remove GST from a tax-inclusive price, calculate CGST and SGST for eligible intra-state transactions, and calculate IGST for eligible inter-state transactions. It is useful for customers, shopkeepers, business owners and students who need quick GST calculations.

To calculate GST on a price, multiply the original price by the GST percentage and divide the result by 100. The formula is: GST Amount = Original Price × GST Rate ÷ 100. Then add the GST amount to the original price to find the final price. For example, if an item costs ₹2,000 and the GST rate is 18%, the GST amount is ₹360 and the final price is ₹2,360. This GST Percentage Calculator makes the calculation simple by displaying the tax amount and total price. Always use the GST rate applicable to the particular product or service.

CGST, SGST and IGST are different components of India's Goods and Services Tax system. For an eligible intra-state supply, GST is generally divided into Central GST (CGST) and State GST (SGST). For example, an 18% GST rate is commonly split into 9% CGST and 9% SGST for such a transaction. For an eligible inter-state supply, Integrated GST (IGST) generally applies instead. This calculator can show a basic CGST and SGST split or an IGST amount according to the transaction type you select. Actual tax treatment depends on the applicable GST rules, place of supply and product or service.

To remove GST from a price that already includes tax, divide the inclusive price by (1 + GST rate ÷ 100). The GST amount is the difference between the inclusive price and the price before GST. For example, if the total price is ₹1,180 and the GST rate is 18%, the price before GST is ₹1,000 and the GST amount is ₹180. This GST Removal Calculator is useful when you know the final price but need to find the original taxable value. Enter the inclusive price and applicable GST rate in the Remove GST section to calculate the pre-tax price and tax amount.

This calculator includes selectable GST rates of 0%, 3%, 5%, 12%, 18% and 28% for convenient calculations. These are commonly referenced GST rate categories, but the applicable rate depends on the product or service, relevant notifications and current tax rules. Do not assume that every product belongs to a particular rate merely because that rate appears in the dropdown. Select the rate applicable to your transaction. For business accounting, invoicing or tax filing, verify the current rate using official GST guidance or consult a qualified tax professional where needed.

A GST-exclusive price is the amount before GST is added, while a GST-inclusive price already contains the tax. To calculate the inclusive price, multiply the exclusive price by (1 + GST rate ÷ 100). For example, a price of ₹1,000 with 18% GST becomes ₹1,180. To calculate the exclusive price from ₹1,180, divide ₹1,180 by 1.18 to get ₹1,000. This GST Inclusive Calculator and GST Exclusive Calculator help you understand the taxable value, GST amount and final amount. They are useful for comparing product prices and checking basic tax calculations.
