1. Adding Tax Formula:
Calculates the markup tax and sums them together:
Tax Amount = Net Price * (Tax Rate / 100)
Gross Price = Net Price + Tax Amount
2. Removing Tax (Reverse Tax) Formula:
Calculates the underlying pre-tax base price from a total price:
Net Price = Gross Price / (1 + (Tax Rate / 100))
Tax Amount = Gross Price - Net Price
