How GST is Calculated?
GST can be calculated simply by multiplying the Taxable amount by GST rate. If CGST & SGST/UTGST is to be applied then CGST and SGST both amounts are half of the total GST amount.
GST = Taxable Amount x GST Rate
If you have the amount which is already including the GST then you can calculate the GST excluding amount by below formula
GST excluding amount = GST including amount/(1+ GST rate/100)
For example: GST including amount is Rs. 1,000 and GST rate is 18%.
GST excluding amount = 1180/(1+18/100) = 1180/1.18 = 1000
