What Is a GST Calculator?

A GST calculator helps you quickly calculate Goods and Services Tax on an amount. You can use it to add GST to a base price or remove GST from a tax-inclusive amount. This is useful for invoices, pricing, budgeting, and understanding how much tax is included in a final figure.

How to Use This GST Calculator

Enter the amount, type in the GST rate, and add your preferred currency label or symbol. Then choose whether you want to add GST or remove GST. Once you click the calculate button, the tool will show the base amount, GST amount, and final amount instantly.

Add GST vs Remove GST

Add GST is used when you want to calculate the final amount after tax. Remove GST is used when you already have a tax-inclusive amount and want to estimate the original price before tax. This helps when reviewing invoices, quotations, receipts, or price comparisons.

Using the GST Calculator with Different Currencies

Because GST is a percentage-based calculation, the same logic works across different currencies. You can use this page with currency codes like USD, PKR, AED, EUR, GBP, CAD, and AUD, or with symbols like €, £, ₹, and ₨. The calculator uses the currency label you enter for display purposes.

Example of GST Calculation

For example, if the original amount is 10,000 and the GST rate is 18%, adding GST will increase the final amount to 11,800. If you start with a GST-inclusive amount and remove GST, the calculator will estimate the original amount before tax and the GST amount separately.
