Is UIF paid on overtime?

What should I get out in total after PAYE and UIF if my salary is R14700-00 and my overtime was R4055-17?

Tax you will pay / PAYE (Pay As You Earn) for your age group and income bracket: R 2716.12 (as per PAYE tables provided by SARS)
Take home pay = Gross salary – PAYE – UIF
UIF / Unemployment Insurance Fund is levied at 1% of your taxable income, at most R148.72/month
Take home pay = R 18755.16 – R 2716.12 – R 148.72
Take home pay: R 15890.32

In summary, UIF is calculated on gross and gross includes overtime.
