Calculating On-Costs: USD 10 Gross Salary

[gibbon85]

Hey,

Gross Salary is USD 10 (Gross salary is 60% of Net Salary)

Flight on-cost = 3% of Net salary
Transport on-cost - 5% of Net salary
Medical on-cost = 3% of Net Salary
Accommodation on-cost = 22% of Net Salary
Gratuity on-cost = 9% of Net Salary

(On-costs total 40% of Net Salary)

How do I calculate what the USD$ value is for each of the on-costs?

Thank you so much for help, and I'm sorry if this is an elementary question!

Hey,

Gross Salary is USD 10 (Gross salary is 60% of Net Salary)

Is this correct? I have never heard of "gross" being smaller than "net"!
Assuming you have those backward and "Net Salary is 60% of Gross Salary" then, with Gross Salary being $10, Net Salary is $6.

Flight on-cost = 3% of Net salary

3% of $6 is $0.18

Transport on-cost - 5% of Net salary

5% of $6 is $0.30

Medical on-cost = 3% of Net Salary

3% of $6 is $0.18 again.

Accommodation on-cost = 22% of Net Salary

22% of $6 is $1.32.

Gratuity on-cost = 9% of Net Salary

9% of $6 is $0.54.

(On-costs total 40% of Net Salary)

Then you have something wrong: 3%+ 5%+ 3%+ 22%+ 9%= 42%, not 40%.

How do I calculate what the USD$ value is for each of the on-costs?
