How do I use 'Remove GST'?

Let's say you sell a product for exactly ₹1,000, and that price already includes 18% tax. You can't just subtract 18% from 1,000. You use the 'Remove' button, and it will calculate the exact base price (₹847.46) and the tax portion (₹152.54).

What are CGST and SGST?

When you sell something within your own state, the government splits the tax directly in half. Half goes to the Central Government (CGST) and half goes to your State Government (SGST). If you sell to a different state, it's just one combined tax called IGST.

What are the standard tax slabs?

In India, the government categorizes different items into different tax buckets. The most common ones are 5% (like basic food), 12% (like computers), 18% (most standard services and goods), and 28% (luxury items like cars).

Can I use this for my official accounting?

Absolutely. The calculator uses standard, precise mathematical formulas to generate these numbers. They are exactly what you need to put on your official tax invoices.

Is my financial data uploaded anywhere?

No. Your privacy is our priority. Every single calculation happens directly inside your own web browser, meaning your numbers never touch our servers.

Make Invoicing Painless

If you run a small business or work as a freelancer in India, dealing with GST (Goods and Services Tax) invoices can be a massive headache. Doing the math in your head to pull 18% tax out of a flat fee usually leads to messy decimals and rounding errors.

This calculator is built to instantly do the heavy lifting for you. Just punch in your numbers, hit a button, and you'll get the exact base price, the total tax amount, and the precise CGST and SGST split you need to write on your bill.

Works Both Ways

Sometimes you have a raw product cost and need to figure out how much to charge your customer after adding tax. Other times, you agree on a flat 'inclusive' price with a client, and you need to reverse-engineer the math to find out what your actual pre-tax revenue is.

Our tool handles both scenarios perfectly. The 'Add GST' function builds your final price, while the 'Remove GST' function acts like a tax extractor, pulling the exact government share out of a final number.
