To calculate GST, you first need two things: the GST rate (for example 5%, 12%, 18%, 28%) and the value on which GST is applicable. Then you apply the rate to arrive at the GST amount and add it to the base value (if you’re calculating a price exclusive of GST).

In day-to-day use, GST is usually calculated in one of two ways:

  • Exclusive of GST: GST is added over and above the base price (common in B2B invoices).
  • Inclusive of GST: The displayed price already includes GST (common in consumer pricing), and you need to split the GST portion out.

A quick example (exclusive):
If the product value is ₹10,000 and GST rate is 18%, GST = ₹1,800 and total = ₹11,800.

1) If the price is exclusive of GST:

  • GST Amount = Base Price × (GST Rate ÷ 100)
  • Total Price (Inclusive) = Base Price + GST Amount

Example:

Base Price = ₹10,000, GST Rate = 18%
GST = 10,000 × 18/100 = ₹1,800
Total = ₹10,000 + ₹1,800 = ₹11,800

2) If the price is inclusive of GST:

  • Base Price = Inclusive Price ÷ (1 + GST Rate ÷ 100)
  • GST Amount = Inclusive Price – Base Price

Example:

Inclusive Price = ₹11,800, GST Rate = 18%
Base = 11,800 ÷ 1.18 = ₹10,000
GST = 11,800 – 10,000 = ₹1,800

A GST calculator automates the same maths you’d otherwise do manually - only faster and with fewer errors. Based on the inputs you provide, it:

  • identifies whether you want a GST-inclusive or GST-exclusive calculation,
  • applies the correct formula,
  • shows you the GST amount, base value, and final value

This is particularly helpful when you’re dealing with multiple invoices, different GST slabs, or when you need to reverse-calculate the base price from an MRP that already includes GST.

Using the 5paisa GST Calculator is straightforward:

  1. Choose if you're a buyer or a seller
  2. Enter the GST amount: Enter the GST exclusive price you want to calculate for.
  3. Select the GST rate: Choose the applicable slab (e.g., 5%, 12%, 18%, 28%).
  4. View the results instantly!

You’ll typically see:

  • GST amount
  • GST Exclusive price
  • total value after GST

This makes it easy to sanity-check invoices and pricing without redoing calculations every time.

  • Saves time on repeated calculations: Especially useful when you deal with multiple bills or frequent pricing checks.
  • Reduces calculation errors: Manual GST calculations often go wrong while reversing inclusive pricing or switching slabs.
  • Quick comparisons across GST slabs: Useful when you’re checking how different rates impact the final payable amount.
  • Better clarity for billing and budgeting: Clear split between base value and tax makes it easier to track costs and taxes separately.

Frequently Asked Questions

A comprehensive, multi-stage, destination-based tax assessed at each stage of value addition is known as the "Goods and Services Tax." GST has replaced the country's numerous indirect taxes, which has helped the Indian government carry out its 'One Nation One Tax' agenda.

The fee is charged on products and services sold for consumption within the borders of India. The tax, which is now in place in most countries with appropriate customizations, has successfully streamlined India's indirect taxation system.

Internally produced goods and services are subject to GST, which depends on the final market price and ultimately reflects in the highest retail price. Consumers pay the tax, which adds to the final cost of any goods or services they purchase. It is first required of the seller to collect, which implies an indirect incidence, before being paid to the government.

The GST rates on various goods and services are applied consistently nationwide. For tax payment, goods and services come under various slab rates. The lower and zero slab rates include necessities, while luxury and comfort items are under higher slabs. The slab rates assigned to necessities are lower or nonexistent, whereas those assigned to luxury and comfort goods are higher. The primary goal of this classification is to guarantee an equitable distribution of wealth among Indian citizens.
 

With the introduction of the GST, taxpayers are now aware of the amount of tax imposed at each location where goods and services are provided. The GST rates that apply to various categories must be considered by taxpayers when calculating GST. The rates under the new tax system are 5%, 12%, 18%, and 28%.

The formula for Calculating GST

Here is the formula to determine GST by the taxpayer.

Add GST: GST Amount = (Original Cost x GST%)/100Net Price = Original Cost + GST Amount
Remove GST: GST Amount = Original Cost - [Original Cost x {100/(100+GST%)}]Net Price = Original Cost - 
GST Amount

Example of GST Calculation

If the retail price of a product is Rs. 2,000 and the GST rate that applies to it is 12%, the product's net price will be Rs. 2,000 + 12% of Rs. 2,000 (or Rs. 2,000 + Rs. 240) (or Rs. 2,240).
 

The following are a few of the main advantages of using a GST calculator:

●    Users can use it to calculate the net or gross product price using GST rates.
●    It allows users to distinguish between SGST, CGST, and IGST and accurately calculate each tax.
●    Instantaneous results allow for time savings.
●    It reduces the possibility of human error when figuring out how much something will cost.
●    It is easy to use and makes calculating GST simple.
