GST stands for Goods and Services Tax. It is an indirect tax generally applied to the purchase of goods and services. Depending on the country and the type of product or service, the applicable tax rate may vary.

A seller generally collects GST or a similar consumption tax from the customer on behalf of the relevant tax authority. The applicable rate differs from country to country. For example:

Therefore, the tax rate is not the same everywhere. Some countries use the term GST, while others use VAT (Value Added Tax) or another name for a similar consumption tax.

For example, if the original price of a product is 25,800 and the GST rate is 15%, the GST amount is 3,870, making the total price including GST 29,670.

Imagine you visit a store and purchase several products such as potatoes, vegetables, rice, lentils, and other goods. The applicable tax is calculated based on the taxable value of the goods or services, and the seller collects the applicable amount from you. This is the basic concept behind GST and similar indirect consumption taxes.

Calculate GST instantly with our free GST Calculator. Add or remove GST, find the tax amount, and get the final price. Example: 25,800 at 15% = 29,670.

A GST Calculator is an online calculator designed to calculate GST based on a specified GST rate. It can help you quickly determine the price excluding GST, GST amount, and price including GST.

The calculator supports two main calculation modes: Add GST and Remove GST. This allows you to calculate GST when you know the pre-tax price as well as reverse-calculate the original price when you already have a tax-inclusive amount.

The Add GST mode calculates the GST amount based on the price excluding GST and then adds the tax to determine the final price including GST.

In this mode, enter: Amount Excluding GST

And GST Rate (%). 

The calculator then displays:

Add GST Formula 1

GST Amount = Price Excluding GST × GST Rate ÷ 100

Add GST Formula 2

Price Including GST = Price Excluding GST + GST Amount

Add GST Example

Suppose the price excluding GST is 25,800 and the GST rate is 15%.

GST Amount = 25,800 × 15 ÷ 100 = 3,870

Price Including GST = 25,800 + 3,870 = 29,670

Therefore:

The Remove GST mode is used when you already know the price including GST and want to calculate the original price excluding GST and the GST amount.

In this mode, enter: Amount Including GST

And GST Rate (%)

The calculator then displays:

Remove GST Formula 1

Price Excluding GST = Price Including GST ÷ (1 + GST Rate ÷ 100)

The parentheses are important because the entire expression 1 + GST Rate ÷ 100 is the divisor.

Remove GST Formula 2

GST Amount = Price Including GST − Price Excluding GST

Remove GST Example

Suppose the total price including GST is 29,670 and the GST rate is 15%.

Price Excluding GST = 29,670 ÷ (1 + 15 ÷ 100)

Price Excluding GST = 29,670 ÷ 1.15 = 25,800

Then:

GST Amount = 29,670 − 25,800 = 3,870

Therefore:

When removing GST, you should not simply subtract the GST percentage from the tax-inclusive price.

For example, if the price including GST is 29,670 and the rate is 15%, calculating "29,670 − 15%" would not give the correct pre-tax price.

Instead, use the reverse GST formula:

Price Excluding GST = Price Including GST ÷ (1 + GST Rate ÷ 100)

This gives the correct tax-exclusive price.

The GST/VAT Calculator can help you calculate taxes on goods and services quickly. Its main features and benefits include:

The calculator supports both Add GST and Remove GST calculations. You can calculate the tax-inclusive price from a tax-exclusive amount or reverse-calculate the tax-exclusive price from a tax-inclusive amount.

You can enter your required GST or VAT rate manually, such as 0%, 5%, 10%, 15%, 18%, 20%, 25%, or any other applicable rate. The calculator does not force you to use a single fixed tax rate.

The calculator uses standard mathematical formulas for adding and removing GST. This helps produce accurate results based on the amount and tax rate you enter.

The calculator is simple to use. Enter the amount and GST rate, select Add GST or Remove GST, and calculate the result.

You do not need to download or install an application. The calculator runs directly in your web browser and performs the calculations on the client side.

You can use the calculator to quickly verify GST calculations shown on invoices, bills, quotations, receipts, and other price documents.

The GST Calculator makes it easy to calculate tax-inclusive and tax-exclusive prices, GST amounts, and final prices. With the Add GST and Remove GST modes, you can quickly calculate GST based on your required tax rate.

Use the GST Calculator to check prices, verify GST amounts, and perform GST calculations quickly and conveniently.
