How to Use This GST Calculator
This calculator handles two types of GST calculations that Indian businesses need every day. Here's exactly what each option does:
Add GST (Exclusive) — When you know the base price
Use this when you have a base price and need to find out how much to charge your customer including GST. For example, if your service costs ₹10,000 and you charge 18% GST, this mode calculates the GST amount (₹1,800) and the final invoice amount (₹11,800).
| Service fee (base price) | ₹10,000 |
| GST @ 18% | ₹1,800 |
| CGST (9%) | ₹900 |
| SGST (9%) | ₹900 |
| Total invoice amount | ₹11,800 |
Remove GST (Inclusive / Reverse) — When you know the MRP or total
Use this when you already have a GST-inclusive price and need to reverse-calculate the base amount and the GST portion. This is commonly used by shopkeepers, traders, and retailers who receive a total invoice and need to split base price from tax for their accounts.
| GST-inclusive total (MRP) | ₹1,180 |
| Base price (extracted) | ₹1,000 |
| GST @ 18% (extracted) | ₹180 |
| CGST (9%) | ₹90 |
| SGST (9%) | ₹90 |
Intra-state vs Inter-state — Which toggle to use
If you are supplying goods or services within the same state (e.g., seller in Punjab, buyer in Punjab), keep the toggle on Intra-state. The GST splits into CGST and SGST — half each.
If you are supplying across states (e.g., seller in Punjab, buyer in Maharashtra), switch to Inter-state. The full GST is charged as IGST — no split. This is also used for exports and imports.
Profit Margin feature
Click "+ Add Profit Margin" to include your profit on top of the cost before GST is applied. This is useful for traders and manufacturers who want to calculate the final selling price including their margin and GST in one step.
Tired of calculating GST manually every invoice?
The right accounting software does this automatically — every invoice, every time, with zero errors.
Frequently Asked Questions About GST in India
IGST (Integrated GST) applies to inter-state transactions — when the supplier and buyer are in different states. IGST equals the full GST rate (18% in this case) and is collected by the central government, which then distributes the state's share. Exports are also treated as inter-state and are typically zero-rated (0% IGST with LUT filing).
