Retirement Calculator
Find out how much you need to retire comfortably, how much you'll have at retirement age, and whether you're on track.
To retire comfortably spending $60,000/year, you need $1.5 million (25× annual spending, 4% rule). A 35-year-old with $80,000 saved, investing $1,500/month at 7% real return, will have $2.4 million by age 65 — right on track.

How it's calculated
Retirement math: target, projection, and comparison
Target = Annual retirement spending ÷ SWR
e.g. $60,000 ÷ 4% = $1,500,000
Projected at retirement =
Current savings × (1+r)^years
+ Monthly × 12 × [(1+r)^years − 1] / r
Annual income from portfolio = Projected × SWR
- Safe Withdrawal Rate (SWR)
- The percentage of your portfolio you can withdraw annually without running out of money. 4% is the classic benchmark (Bengen, 1994) for 30-year retirements.
- Real return
- Return after inflation. Using real returns and real spending means you don't need to model inflation growth separately.
- Nest egg
- The total retirement portfolio needed to fund your retirement spending through the safe withdrawal rate.
Disclaimer: this calculator uses constant return assumptions. Actual returns vary. Does not include Social Security, pension income, or taxes on withdrawals. Consult a financial adviser for personalized planning.
Frequently asked questions
How much do I need to retire?
The most common benchmark: 25× your annual retirement spending (4% SWR). If you plan to spend $60k/year: need $1.5M. For a longer early retirement, use 28–30× expenses (3.5% SWR). Include expected Social Security/pension income to reduce the target.
How much should I save for retirement each month?
Aim for 15–20% of gross income including employer match. Earlier starters can save less; starting later requires more. Even saving 10% consistently from age 25 builds significant wealth by 65 thanks to compounding.
What is a 401(k) and should I max it out?
A 401(k) is a US employer-sponsored tax-deferred retirement account. 2026 limit: $23,500 ($31,000 if 50+). Always contribute at least enough to get the full employer match first — that's a 50–100% instant return. Then max an IRA before adding more to 401(k).
What is Social Security and how does it affect my retirement?
Social Security is a US government retirement benefit funded by payroll taxes. In 2026, average monthly benefit ≈ $1,900. Your benefit amount depends on your earnings history and the age you start claiming (62–70). Include expected Social Security income to reduce the savings target in this calculator.
