In simple words, “Credit on tax can be claimed by a supplier on the output of goods and set off against tax paid earlier on the input of the goods”. The idea is to reduce the cascading effect and lessen the tax burden, ultimately eliminating dual tax payments.
A person/business that is registered for Goods and Services Tax (GST) can efficiently claim the tax amount paid on their inward supplies, inputs, or raw materials as a credit when paying taxes on their sales or outward supplies of goods.
Let us now understand ITC calculation by taking a simple example to further understand how to calculate Input tax credit.
A manufacturer’s final tax output comes out to be INR 1000 which he needs to pay on the final goods but during the whole process, he already has paid taxes of INR 250 and INR 300 on the initial purchase of the goods. Now the scenario is the tax already paid by the manufacturer is INR 550 (250+300), which is eligible for the tax credit and the manufacturer can claim this amount at the time of the tax to be paid on the final goods i.e.; 1000. So the tax needs to be paid by him is reduced to INR 450 (1000-550). Hence, we can conclude that
Tax credit availed: INR 550 (250+300)
Tax on output : INR 1000
Tax to be paid: INR 1000-INR 550 = INR 450
Let’s further understand ITC calculation formula in GST with respect of GST and value of Goods: -
Assume you have a business and the GST you have to pay is 18% on the raw material purchased. The cost of the raw is INR100, so the tax paid will be 18 which needs to be paid by the manufacturer.
Now the final goods are ready, the manufacturer sells the final goods worth INR 300 with the GST of 18% making the tax component 54 and the total cost of the final goods 354 (300+54). But at the time of filing the return, the manufacturer can claim 18 as input credit already paid. And deposit 36 as the final tax liability with the government.
Remember ITC is a tax imposed on value addition on the goods and services and not on final goods.
Although the utilization is through a waterfall mechanism through various stages of IGST/CGST/SGST
So to summarize till now what we have learned of the input tax credit formula under GST would be as below: -
GST payable = Output GST- Input GST (Input GST and output GST)
How to calculate Output GST: GST on sale of the final goods
How to calculate Input GST: GST on purchase of the raw material
We clearly understand the benefits of the ITC: -
There are few exemptions of ITC on goods or services which can’t be claimed. Good exclusively used for: -

Input tax credit serves as a crucial tool for businesses to minimize their GST obligations. It is essential to consider factors such as filing GST returns promptly, ensuring invoice accuracy, and claiming ITC only for eligible inputs while doing ITC calculation in GST. By adhering to the outlined procedures and considering key factors, businesses can precisely compute their ITC in GST and assert it promptly.
