What this topic covers

Retirement planning works best as a sequence rather than a single calculation. First define the life you are funding: essential spending, discretionary spending, one-off goals and a margin for the unexpected. Then build the foundations — an emergency fund, adequate insurance, and control of high-interest debt — before optimising investments.

Next, measure. Track net worth and savings rate, project the corpus forward with realistic inflation and returns, and compare it with a target that reflects your actual spending rather than a generic multiple of income. Only then choose a withdrawal strategy, because the right one depends on the size of the corpus, the length of retirement and how flexible your spending can be.

Finally, review on a schedule. A plan is a set of assumptions, and assumptions age. The planning guide walks through the decisions; the retirement planning calculator turns them into a year-by-year projection you can revisit.
