What is GST (Goods and Services Tax)?
GST stands for Goods and Services Tax. It is a comprehensive, multi-stage, destination-based indirect tax levied on the manufacture, sale, and consumption of goods and services. Adopted by many countries globally (including India, Australia, Canada, and New Zealand), GST replaces multiple cascading taxes to create a single, unified tax system.
For businesses, calculating the exact GST amount to charge customers or the amount of Input Tax Credit (ITC) they can claim is a daily necessity. For consumers, understanding how much of a product's price goes toward taxes helps in making informed purchasing decisions.
How to Use the GST Calculator
Our GST calculator is designed to be quick and foolproof, allowing you to both add GST to a base price or extract GST from a total price:
- Initial Amount: Enter the base price of the good or service.
- GST Rate (%): Enter the applicable tax rate (e.g., 5%, 12%, 18%, or 28%).
- Add GST vs. Remove GST:
- Select "Add GST" if you have the base price and need to find out the final selling price including tax.
- Select "Remove GST" if you have the final receipt total and need to reverse-calculate the base price before taxes were applied.
The Mathematical Formula for GST
If you need to calculate GST manually, here are the standard formulas used by accountants and billing software:
Formula for Adding GST:
GST Amount = (Original Cost × GST Rate) / 100
Final Price = Original Cost + GST Amount
Formula for Removing GST (Reverse Calculation):
GST Amount = Total Cost - [Total Cost × {100 / (100 + GST Rate)}]
Base Price = Total Cost - GST Amount

Frequently Asked Questions
In dual-GST systems like India's, the tax is split based on the transaction type. CGST (Central GST) and SGST (State GST) are levied equally on intra-state sales (sales within the same state). IGST (Integrated GST) is levied on inter-state sales (sales between two different states) and is collected entirely by the Central Government.
Input Tax Credit allows a business to reduce the tax they have already paid on inputs (raw materials or services) from the tax they need to pay on their final output. This prevents the "cascading effect" (tax on tax) and ensures that only the value addition is taxed at each stage of the supply chain.
Yes, most countries have a list of essential items that are exempt from GST or taxed at a 0% rate. These typically include basic food items, fresh produce, educational services, and healthcare services. However, the exact list of exempt items varies heavily by country and local tax laws.
To find the original price before GST was added, you need to divide the total price by (1 + GST Rate). For example, if the total price is $110 and the GST rate is 10%, the calculation is $110 / (1 + 0.10) = $110 / 1.10 = $100. The GST amount is the difference: $110 - $100 = $10.
