Sorry i mean calculation is tough to understand. But buddy thanks a lot to help me in this calculation. Now i m reading the calculation format. Thanks a lot for the fast help

The calculation you showed is
actualAmount = swipeAmount - (swipeAmount*chargeRate) - (swipeAmount*chargeRate*rateGST)
Hence
swipeAmount = actualAmount / (1 - chargeRate * (1 + rateGST))
