GST Calculator

What is the GST Calculator?

GST Calculator is an online financial calculator that accurately estimates the GST payable on any product or service you purchase as per the applicable GST rate. The calculator estimates the total cost of the purchase, including and excluding GST, based on the applicable GST rate and the cost of the product or service.

Different GST rates are applicable based on the type of product and service. Knowing the GST on your purchase beforehand would help you get an accurate estimate of the total cost, allowing you to make informed financial decisions.

How to Use the GST Calculator?

Here's how you can use the GST calculator to find the GST payable on your next purchase.

• Step 1: Enter the cost of the product or service you plan to purchase by using the slider or manually entering the amount.
• Step 2: Enter the GST tax rate applicable to the product or service. For example, jewellery attracts 3% GST, with an additional 5% GST charged separately on jewellery-making charges.

Once you've entered the GST rate, the GST calculator will instantly calculate the total GST payable along with the cost of the product or service before or after GST.

Formula Used to Calculate GST

The following formula is used to calculate GST on the purchase of products and services.

GST Amount = (Net Value of good/service x GST%) / 100

Hence, Final Price = Net Value of good/service + GST Amount

When GST is already included, and the reverse GST Amount is required:

GST Amount = Gross Value of good/service – [ Gross Value of good/service x (100/(100 + GST%))]

For example, say a product is net priced at ₹5,000, and the GST slab to be levied is 18%.

GST = (5,000 x 18) / 100 GST = ₹900

Here, IGST is ₹900, or if CGST & SGST are to be levied, it would be ₹450 each.

Similarly, if the gross price of a good is ₹5,900, and GST is levied at 18%:

GST = 5,900 – [5,900 x (100/(100 + 18))] GST = 5,900 – [5,900 x 0.84] GST = 5,900 – 5,000 GST = ₹900

Here, IGST is ₹900, or if CGST & SGST are to be levied, it would be ₹450 each.
