Retirement planning is often reduced to one question: “How much capital do I need?” The more useful starting point is the life that capital must support.
Future income needs depend on expected spending, housing, healthcare, dependants, debt, tax and how long retirement may last. Some costs may disappear; others may rise. Income can come from several places: retirement funds, annuities, investments, work, property or public benefits. Each may behave differently.
So a capital target is an output of assumptions, not a magic number. Two people with the same savings can have very different positions because their spending, income sources and flexibility differ. The plan must also allow for inflation and for returns arriving in an uncertain order.

Estimate one month of retirement spending in today’s rand. Separate essential, flexible and temporary costs. Then list every expected income source and mark whether its amount is guaranteed, variable or unknown.
Ask your advisor
- What level of after-tax income is the plan trying to support?
- Which spending, inflation and lifespan assumptions create the capital target?
- How would the plan respond if one assumption is wrong?
Retirement planning does not predict a single future. It tests whether available resources can support a range of plausible futures.
