How Our GST Calculator Works
This tool provides three distinct modes to handle various business scenarios, ensuring you get the exact numbers you need.
GST on Net Price
The simplest mode. Enter the price of your goods or services before tax, select a GST slab, and the tool adds the appropriate tax amount to give you the final gross price.
GST with Production Cost
Ideal for manufacturers. Input your production cost and desired profit margin. The calculator determines the selling price and then applies the correct GST on top.
GST with Purchase Price
Perfect for wholesalers and retailers. Enter the price at which you purchased the goods and your profit margin to find the final selling price inclusive of GST.
Understanding CGST, SGST, and IGST
Goods and Services Tax (GST) in India is structured into three components depending on the nature of the transaction. Our calculator handles this automatically.
CGST
Central Goods and Services Tax is levied by the Central Government on intra-state (within the same state) transactions.
SGST
State Goods and Services Tax is levied by the State Government on intra-state transactions. The total tax is split 50/50 between CGST and SGST.
IGST
Integrated Goods and Services Tax is levied by the Central Government on inter-state (between two different states) transactions.
Who Should Use This GST Calculator?
Buyers
As a buyer, you can use this tool to verify the GST amount charged on an invoice. Simply enter the price and GST rate to ensure you are paying the correct tax.
Manufacturers
Determine the final selling price of your products by inputting the production cost and your desired profit margin. The calculator adds the correct GST to help you set prices accurately.
Wholesalers & Retailers
If you are a wholesaler or retailer, calculate the selling price by adding your profit margin to the purchase price, with the correct GST applied automatically. This is essential for creating a tax invoice.
