Retirement savings calculatorRetirement Income Sustainability Planner
Retirement income is a journey—not a single percentage.
Start at 4%, then test inflation, changing spending needs and the order in which investment returns arrive.
Your starting position
Give every year of retirement a financial foundation.
Living-annuity capital funds regular income. Accessible savings can cover a planned once-off cost and supplement income if a future drawdown would exceed the living-annuity limit.
Choose your starting question
Start from capital, or start from income.
Income and investment path
Plan for inflation—and for retirement to change shape.
The return is after investment fees. Income is paid monthly at the beginning of each month before that month's investment growth.

The base plan works—but needs active monitoring
The model maintains base income, but market sequencing or future drawdown limits create pressure.
Sequence-of-returns risk
The average return is only part of the retirement story.
The early- and late-shock paths use the same five annual return adjustments in a different order. Withdrawals during early losses can permanently reduce the capital available for recovery.
The early-shock path ends with this much less capital than the late-shock path, despite using the same set of long-term annual returns.
Retirement capital journey
Smooth path versus the timing of market shocks.
Age runs from left to right. The vertical scale shows projected nominal capital in rand. The three lines use the same starting capital and income plan.
How this estimate works
Useful planning—without pretending retirement is predictable.
- Living-annuity range
- The current selectable drawdown range is 2.5%–17.5%, normally reviewed annually. The model flags when required income would exceed 17.5%.
- 4% starting point
- The default living-annuity income is 4% of opening capital, paid monthly. It is a planning assumption, not a guarantee.
- Payment timing
- Income is withdrawn at the beginning of each month, followed by that month's investment return.
- Investment return
- The entered return is after investment fees but before personal income tax on annuity payments.
- Tax estimate
- Starting after-tax income uses the 2026/27 individual tax table and age rebates. Medical credits and individual deductions are excluded.
- Sequence scenarios
- Early and late shocks reorder the same return adjustments. Lower-return, higher-inflation and combined scenarios change additional assumptions.
- Accessible savings
- Used for the entered once-off cost and to supplement income above the modelled 17.5% living-annuity ceiling.
- Spending phases
- Essential and lifestyle spending follow general inflation. Healthcare follows its separate inflation assumption and phase multiplier.
