Goods and Services Tax (GST) is a unified indirect tax across India that replaced multiple previous taxes like VAT, Service Tax, and Excise Duty. Whether you are a business owner issuing an invoice or a consumer verifying a bill, calculating GST accurately is essential.
Our GST Calculator is a versatile tool that allows you to calculate both "GST Exclusive" (Adding Tax) and "GST Inclusive" (Removing Tax) amounts instantly.

Manual calculations can be prone to errors, especially when working with "Reverse GST" (finding the original price from a total bill). This tool helps you:
- Generate Invoices: Quickly find the total bill amount by adding 18% or 12% GST to your base price.
- Verify Bills: Check if a vendor has charged you the correct tax amount.
- Reverse Calculation: Find the actual cost of a product if you only know the MRP (Maximum Retail Price).
Who can use this tool?
- Retailers & Wholesalers: For quick billing and checking margins.
- Freelancers: To add 18% GST to their service invoices.
- Shoppers: To calculate the tax component in their purchases.

Calculation Examples
Example 1: Adding GST
A freelancer charges ₹10,000 for a service. The GST rate is 18%.
- GST Amount: (10,000 × 18) / 100 = ₹1,800
- Total Invoice Value: ₹10,000 + ₹1,800 = ₹11,800
Example 2: Removing GST (Reverse Charge)
You bought a phone for ₹23,600 inclusive of 18% GST. What is the actual price of the phone?
- Base Price: 23,600 / (1 + 18/100) = 23,600 / 1.18 = ₹20,000
- GST Paid: 23,600 - 20,000 = ₹3,600
