How Should I Calculate GST?

Goods and Service Tax can be calculated in simple steps. If you understand the simple formula that is applied in the calculation then you can do it yourself. However, GST equals the multiplication of the taxable amount and GST rate. That means, GST = taxable amount X GST rate

In case you require CGST, SGST/UTGST then for CGST or SGST you will have to halve the total GST amount.

In case you obtain an amount that is GST inclusive, then to know the value of the GST you must apply the formula that states:
GST ( after subtracting amount) = GST ( added to amount)/(1 + GST rate/100)
Practical Example:

If GST including amount is INR 525 and GST rate is 5 percent then the value of GST shall be as follows:
GST ( after subtracting amount) = 525/(1+5/100) = 525/1.05 = 500
