UIF Unemployment Estimate
The unemployment calculator estimates UIF benefits using salary, working months, the UIF salary ceiling, daily income, income replacement rate, and credit days.
- Salary is capped at R17,712.00 per month for calculation purposes.
- Daily income is calculated as monthly salary multiplied by 12, divided by 365.
- The income replacement rate uses the UIF sliding-scale formula used in the calculator.
- Working months are converted to days using 365 divided by 12.
- Credit days are estimated as one credit day for every four days worked, capped at 365 days.
Leave Benefit Estimate
The leave calculator estimates a daily UIF top-up by comparing normal daily income with leave-period daily income and applying the UIF benefit formula used by the site.
Actual maternity, adoption, parental, or illness benefit outcomes depend on official rules, forms, contribution history, employer declarations, and adjudication.
VAT and Compound Interest
The VAT calculator uses the rate entered by the user, with South Africa's standard VAT rate shown by default. The compound interest calculator applies standard compound-growth formulas with optional recurring contributions.
