How Much Do I Need to Retire at 62 with $150,000/Year Spending?
To retire at age 62 with $150,000/year in spending, you need approximately $3,750,000 — that is 25× your annual expenses, based on a 4% safe withdrawal rate over your expected 28-year retirement (to age 90).
Conservative target ($4,615,385 at 3.25% withdrawal) accounts for sequence-of-returns risk; aggressive target ($3,333,333 at 4.5% withdrawal) assumes good first-decade returns. After expected Social Security offset (~$500,000), net portfolio target drops to ~$3,250,000.
The numbers
How much to save monthly (by start age)
Required monthly savings to reach $3,750,000 by age 62, assuming a 7% annual real return (typical for diversified equities after inflation):
Notice how dramatically the required monthly drops with earlier starts. Time inside the exponential function dominates everything else — a person starting at 25 needs a fraction of what someone starting at 40 needs to hit the same target.
Lump-sum equivalent today
If you could invest a lump sum today and never add another dollar, here is what you would need at each starting age (assuming 7% real return):
Why the 4% withdrawal rate?
The 4% rule comes from Bengen (1994) and the Trinity Study (1998), which back-tested 30-year US-market retirements and found a 95%+ success rate at 4% inflation-adjusted annual withdrawals from a balanced stock/bond portfolio. For your 28-year retirement, the standard 4% rule applies cleanly. The 4% rate used here reflects that adjustment.
The lever you can actually pull: spending
Cutting $5,000 of annual expenses isn't just $5,000 saved per year — it reduces your FI number by $125000 because you need to fund less for 28 years. Conversely, lifestyle inflation of $5,000/year increases the goalpost by the same amount. This is why frugality compounds: every dollar of expenses you eliminate today is roughly 25 dollars of portfolio you don't need to accumulate.
Frequently asked questions
How much money do I need to retire at 62 with $150,000 annual spending?
Short answer: $3,750,000, calculated as $150,000 × 25 (the inverse of a 4% safe withdrawal rate over a 28-year retirement).
How much should I save monthly to retire at 62?
Short answer: Starting at age 25: $1,789/month. Starting at age 30: $2,625/month. Starting at age 35: $3,918/month. Starting at age 40: $6,003/month. Starting at age 45: $9,612/month. All assume 7% annual real return.
What withdrawal rate is safe for a 28-year retirement?
Short answer: Approximately 4%. The classic 4% rule was calibrated for 30-year retirements. Longer retirements need lower rates because portfolios face more bad-sequence years.
Does Social Security count toward my retirement number?
Short answer: Yes. At full retirement age (67), SS provides ~$30K/year, equivalent to ~$750K of portfolio. After SS, your net target drops to $3,250,000.
