# Service Charge on Sub Total, from that Total i want the Final Total to have Tax added

Am bad at explaining things so i am detailing here what i want to accomplish in steps below.

1. Calculate the Service Charge:

Service Charge = Ticket Total * Service Charge Rate
Service Charge = \$25.00 * 0.05 = \$1.25

1. Add the Service Charge to the Ticket Total:

New Total = Ticket Total + Service Charge
New Total = \$25.00 + \$1.25 = \$26.25

1. Calculate the GST:

GST = New Total * GST Rate
GST = \$26.25 * 0.08 = \$2.10 (rounded to 2 decimal places)

1. Add the GST_Tax to the New Total: (GST is TAX)

Final Total = New Total + GST_Tax
Final Total = \$26.25 + \$2.10 = \$28.35

So, the final bill total after adding a 5% service charge and 8% GST is \$28.35.

Summary of Steps:

1. Calculate Service Charge:

Service Charge = \$25.00 * 0.05 = \$1.25

2)Calculate New Total after Service Charge:

New Total = \$25.00 + \$1.25 = \$26.25

1. Calculate GST:

GST = \$26.25 * 0.08 = \$2.10

1. Calculate Final Total:

Final Total = \$26.25 + \$2.10 = \$28.35

How can i achieve this in a new setup after adding the products. If this was answered before, please point me to it, thanks

So you want tax to apply after service charge?

Yes, I want the tax (GST) to be applied after adding the service charge to the ticket total.

Make sure this option is un-selected

could you please tell me how i can set up the GST tax too after service chargeâ€¦

do i need to add Tax to the calculation selectors ?
the Tax should actually display 2.10
and the balance should show as 28.35
