GST Calculator
The DhanLift GST Calculator helps individuals, freelancers, and business owners quickly compute the Goods and Services Tax on any transaction. Enter the base price and select the applicable GST slab to instantly see the GST amount and the final inclusive price.
India's GST system has four main slabs - 5%, 12%, 18%, and 28%. Different goods and services attract different rates. This calculator supports all standard slabs and works in both directions: compute GST on a base amount, or back-calculate the base price from a GST-inclusive amount.
Accurate GST computation is essential for invoicing, budgeting, and compliance. Use this tool to validate amounts before raising invoices or filing returns.
Whether you're a business owner, freelancer, retailer, accountant or consumer, the GST Calculator helps you accurately calculate GST-inclusive and GST-exclusive prices, split CGST & SGST for intra-state transactions, and estimate IGST for inter-state transactions.
How to Use GST Calculator?
Enter the base price of the product or service (excluding GST).

The calculator instantly shows you the GST amount and the total price including GST.
To reverse-calculate, toggle to 'GST Inclusive' mode and enter the final price to see the base amount.
Formula for GST Calculation
For reverse calculation (price inclusive of GST): Base Price = Total Price ÷ (1 + GST Rate ÷ 100)
