Disclaimer: This calculator is for educational and illustrative purposes only. It uses 2025/2026 SARS income tax tables with the primary rebate of R 17,235. Results are approximate and exclude medical tax credits, UIF, and SDL. The annual RA deduction limit of R 430,000 reflects the 2026/2027 tax year as published. Retirement projections assume constant contributions and a fixed nominal return — actual returns will vary. This does not constitute financial advice.
