Hi All, I was wondering if it is possible to work out a formula for calculating what your gross earnings would have to be to earn a certain net value. The tax on earnings scales go like this: Between $0 - $6000 you pay no tax. Between $6001 - $25000 you pay 15c per dollar. Between $25001 - $75000 you pay 30c per dollar. Between $75001 - $150000 you pay 40c per dollar. Greater than $150000 you pay 45c per dollar. So Gross - Tax = Net. Based on the above I'd like to be able to solve what your gross would be if you knew your net earnings. Does anyone know how to write the formula for this? I'm having trouble just writing a formula to explain the above solving for gross. Brad.
