Start with annual gross pay
A planning calculator usually annualises salary, adds any bonus and then estimates annual income tax before showing an average monthly take-home amount.
UIF is separate from income tax
UIF is a payroll contribution. The employee contributes 1% up to the monthly earnings ceiling, and the employer contributes a separate matching amount.
Retirement contributions can matter
Retirement contributions may reduce taxable income subject to rules and caps. A simplified calculator can model the impact, but a payslip or tax return may apply the exact rules differently.
Use the result as a planning number
The estimate is useful for comparing jobs, salary increases or deductions. It should not be treated as a guaranteed payslip amount.

Does UIF affect take-home pay?+
Yes. Employee UIF is deducted from pay, subject to the monthly contribution ceiling.
