How Much Do You Need to Retire?
The standard rule is to accumulate 25× your annual expenses (the 4% withdrawal rule). This means if you spend $60,000/year, you need $1.5M. A more conservative 3.5% SWR (for longer retirements) requires $1.71M.

Frequently Asked Questions
A common guideline: save 15% of gross income starting at age 25. Starting at 35 may require 20–25%. Time is your biggest advantage — starting 10 years earlier typically halves the required monthly contribution for the same retirement outcome.
Long-term diversified portfolios have historically returned 7–10% annually (nominal). Use 5–7% for conservative planning in real terms (after inflation). For South Africa, the JSE has historically returned ~12% nominal, but consider inflation of 5–6%.
The 25x rule says save 25 times your annual expenses. Needing $60,000/year means saving $1.5 million. This is based on the 4% safe withdrawal rate — withdrawing 4% annually gives a high probability of the money lasting 30+ years. Social Security and pension income reduce how much you need to save independently.
The most common rule is 25× your annual retirement expenses (based on the 4% safe withdrawal rate). If you plan to spend $60,000/year in retirement, you need $1.5 million. Factor in Social Security income — the average benefit in 2026 is approximately $1,900/month, reducing how much your portfolio must cover.
The 4% rule states you can withdraw 4% of your retirement portfolio in year one, then adjust for inflation each year, with a high probability of the money lasting 30 years. Based on the Trinity Study using historical US market returns. Some planners now use 3–3.5% for longer retirements or conservative portfolios.
You can claim Social Security from age 62 (at a permanent reduction of up to 30%), full retirement age of 66–67 (full benefit), or up to age 70 (earning delayed credits of 8% per year). Delaying from 67 to 70 increases your monthly benefit by 24%. Break-even analysis favors delay if you expect to live past 80.
