Retirement Planning Calculator for South Africans 2026
Retirement planning comes down to one core question: will your savings, growing at a realistic rate, actually cover your expenses by the time you retire? Here's how to work it out.
The core formula
Future value of your retirement savings = Current savings × (1 + rate)^years, plus the future value of your ongoing monthly contributions compounded at the same rate. The more years you have and the higher your net (after-fee, after-inflation) return, the more compounding does the heavy lifting for you.
South Africa-specific factors to build in
- Tax-deductible contributions: retirement annuity and pension/provident fund contributions are tax-deductible up to 27.5% of your taxable income (capped at R430,000/year) — this is a real, immediate saving worth factoring into your net contribution cost.
- Tax-free savings: once you've maximised retirement deductions, a tax-free savings account (R46,000/year, R500,000 lifetime, per SARS) lets further growth compound completely tax-free.
- Two-pot system: since the two-pot retirement reforms, one-third of new retirement contributions go into a "savings pot" you can access before retirement, and two-thirds into a "retirement pot" locked until retirement — this changes how much is actually available to you and when.
- Inflation: use a realistic net-of-inflation return when projecting, not the nominal market return, or you'll overestimate what your future rand will actually buy.
A simple sanity check
A common rule of thumb is that you'll need roughly 15x your final annual salary saved to maintain your lifestyle in retirement — treat this as a rough benchmark to check your trajectory, not a precise target, since your own expenses, other income sources, and retirement age all shift the real number.
