A GST calculator is an online tool that quickly computes the Goods and Services Tax on any amount. You enter the base price and the GST rate, and the calculator shows the tax amount and the final price including GST. Tez Invoice offers a free GST calculator that works for all GST slabs used in India including 5%, 12%, 18%, and 28%.
This tool is used by business owners, accountants, shopkeepers, and anyone who needs to add or remove GST from a price quickly and accurately.
Calculating GST manually is straightforward for one item but becomes error-prone when handling multiple transactions or different GST rates. A free online GST calculator gives you instant, accurate results without any risk of calculation mistakes.
It also saves time during invoicing. Instead of switching between spreadsheets and paper calculations, you can get GST-inclusive or GST-exclusive prices in seconds.
India has four main GST rates: 5%, 12%, 18%, and 28%. Essential goods like food and medicine are often exempt or taxed at 0% or 5%. Standard goods and services fall in the 12% to 18% range. Luxury and sin goods attract 28%.
If you are unsure which rate applies to your goods or services, check the official GST rate schedule or consult a tax professional. Always apply the correct rate on your invoices.
Enter the original price or base amount in the input field. Select the GST rate that applies to your product or service. Choose whether you want to add GST to the base price or remove GST from a GST-inclusive price.
The calculator instantly shows the GST amount and the final total. You can use these figures on your invoice or for accounting purposes.
A GST-exclusive price is the base price before tax is added. A GST-inclusive price already has GST built into it. This calculator handles both scenarios so you can find either the tax amount to add or the tax amount already included in a price.
For most sales invoices in India, you start with the base price and add GST. But when you receive a payment that includes GST, you may need to extract the base price, which this reverse calculation handles.
GST is India's unified indirect tax that replaced VAT, service tax, and several other levies in 2017. VAT is still used in many other countries as a consumption tax. Sales tax is common in the United States. If you need to calculate VAT or sales tax, Tez Invoice has separate calculators for those too.
This GST calculator is specifically designed for Indian GST slabs and terminology.
