A Monte Carlo retirement projection built on SARS tax tables, the two-pot system, living annuity drawdown limits, and the SASSA Older Person's Grant — not a rule of thumb.

Income in your first year of retirement
Where that income comes from
Your living annuity's drawdown rate over time
Tax paid over time
Plan robustness
Your baseline success rate compared with a severe market crash landing right at retirement — the single riskiest moment for a drawdown plan (sequence-of-returns risk).

Tax efficiency
Tax-free savings account
Long-term / frail care
Not modelled as a separate cost in this simulation. Private frail-care and nursing facilities in South Africa are commonly quoted in the R15,000–R35,000+/month range, and a stay can last years — a cost that could materially change your success rate if it isn't already covered by medical aid, a gap cover policy, or family support. To see the effect on your plan, add a large one-time expense as a "lump sum" what-if (with a negative amount) on the Optimise tab.

Insights
Automated analysis of your simulation — not a live AI, no chat. Each observation below comes from actually re-running your plan with one thing changed, using the same random market paths for a fair comparison.
What could you do differently?
Three classic retirement levers — each re-run against your plan to find exactly where the line sits, using the same random market paths as your baseline. Below target, each shows what it would take to get there; above target, how much room you have to spare.
Retirement age
Monthly spending
Monthly savings
Leave a legacy
How much could still be left over for family, or a cause you care about, instead of spending down to the last rand.
What-if scenarios
Choices within your control — retiring later, spending less, taking on more risk — as opposed to the Stress test tab's shocks that happen to you. Add one or more below; each stacks on top of the last, in the order you add them, so you can see where a combination of changes actually lands you.

Stress test
Shocks, one at a time
Success rate under each shock, at three severities, applied on top of your plan above. Same random market paths across every cell, so severities compare cleanly.
