What is the difference between CGST and SGST?

CGST (Central GST) and SGST (State GST) are the two components of standard intra-state GST. The total GST amount is simply divided equally (50/50) between the Central and State governments.

The Ultimate GST Calculator for Billing & Accounting

Goods and Services Tax (GST) calculations can often be confusing, especially when you need to reverse-engineer an inclusive price to find the base amount. Our Premium GST Calculator simplifies this entire process for business owners, accountants, and freelancers. It operates in real-time, giving you split-second accuracy without needing a physical calculator.

How Does "Add GST" vs "Remove GST" Work?

Add GST (Exclusive): Use this when you have the base cost of a product/service and need to calculate the final price to charge your customer. The tool calculates the GST and adds it to your initial amount to create the Gross Total.
Remove GST (Inclusive): Use this when you have the final price that already includes GST (like MRP), and you need to extract the original base price and the tax amount for accounting or tax filing purposes.

Understanding CGST and SGST

In India's dual GST structure, intra-state sales (sales within the same state) require the total GST to be divided equally into two parts: CGST (Central Goods and Services Tax) and SGST (State Goods and Services Tax). For example, if the total GST slab is 18%, our tool automatically splits it into 9% CGST and 9% SGST for your invoice formatting.

Frequently Asked Questions

How do you manually calculate GST inclusive amount?

To find the base amount from a GST inclusive price, use the formula: Original Cost = GST Inclusive Price / (1 + (GST Rate / 100)). Our calculator applies this formula instantly when you select "Remove GST".

Is my financial data uploaded to the server?

No. Your financial calculations are processed entirely offline within your own web browser using local JavaScript. We do not track, upload, or save any of your billing amounts.

Can I use custom GST rates?

Yes! While we provide quick-select buttons for the standard slabs (3%, 5%, 12%, 18%, 28%), you can type any custom percentage (e.g., 0.25% or 1.5%) directly into the custom rate input box.
