How much money do I need to retire?

The most common rule of thumb is 25× your desired annual income (based on a 4% withdrawal rate). If you want $60,000/year, you need $1.5M. With Social Security providing $20,000/year, you only need $40,000 from savings, requiring $1M. Your number depends on your income goal, expected Social Security, withdrawal rate, and how many years of retirement you plan for.

What is the average retirement age in the US?

The average retirement age in the US is about 61–63 for those who retire voluntarily, per Gallup surveys. Social Security full retirement age is 66–67 depending on birth year. Financial planners often plan for 30+ years of retirement when retiring at 62–65 and living to 90–95.

What is the 4% rule for retirement?

The 4% rule (from the 1994 Trinity Study) states that withdrawing 4% of your portfolio in year 1 and adjusting annually for inflation has historically sustained portfolios for at least 30 years. A $1M portfolio at 4% provides $40,000/year. Critics note the rule was derived from historical US returns and may be conservative for 40+ year retirements — 3–3.5% is more robust for longer horizons.

How does Social Security affect my retirement age?

Social Security reduces how much you need to withdraw from savings. If your Social Security benefit is $2,000/month ($24,000/year) and you want $60,000/year total, you only need $36,000/year from savings. At 4%, that requires $900,000 instead of $1.5M — a significant difference in years worked. Check your estimated benefit at ssa.gov.

What is a safe annual contribution rate for retirement?

Most financial planners recommend saving 15% of gross income for retirement (including employer match). At 25 with a $60,000 salary, that's $9,000/year. Starting later requires higher rates — starting at 35 may require 20–25% to reach the same outcome. The maximum 401(k) contribution for 2026 is $24,500 (under 50) or $32,500 (50+).

How does inflation affect retirement calculations?

Inflation erodes purchasing power over time. A $60,000 income goal in today's dollars requires $108,000/year if you retire in 30 years at 2% inflation — so you need a larger nest egg than it appears. This calculator uses real returns (inflation-adjusted) to keep everything in today's dollars, making comparisons intuitive.

At what age should I retire?

There is no universally correct retirement age — it depends on your savings, health, income needs, and Social Security strategy. Financially, retiring at 65 vs. 62 has two advantages: three more years of contributions grow your portfolio, and you avoid three more years of withdrawals. Social Security also pays more. Retiring at 70 vs. 65 adds 8% per year in SS benefits (40% more at 70 vs. 66), which can reduce required portfolio withdrawals by $500–$1,000+/month. Many financial planners suggest working until Medicare eligibility at 65 to avoid costly private health insurance.

How does retiring early affect Social Security?

Claiming Social Security before your Full Retirement Age (FRA — 66–67 depending on birth year) permanently reduces your monthly benefit. At 62, you receive approximately 25–30% less than at FRA. At 70, you receive 24–32% more than at FRA (8% per year from FRA to 70). The break-even age between claiming early vs. late is typically around 78–80 — if you expect to live past 80, delaying to 70 provides more lifetime income.

How much do I need to retire at 55?

Retiring at 55 means your portfolio must last 35–40+ years instead of 25 years. Using a 3.5% withdrawal rate (more conservative for long horizons) and a $70,000/year income need with $15,000/year in Social Security (not claimable until 62 at earliest), you need $70,000 − $0 SS for the first 7 years, then $55,000/year from savings. Roughly: $55,000 ÷ 0.035 = $1.57M in savings at age 55. Without Social Security until 62, you must self-fund those first 7 years — add approximately $490,000 to bridge that gap, for a total target near $2M.

Retirement Age Calculator — When Can I Retire?

Estimates when you can retire based on savings, contributions, income goal, and Social Security — inflation-adjusted.

How to Use This Retirement Age Calculator

This retirement age calculator finds the earliest year you can retire based on your savings, contributions, and income goal. Enter your current age, current retirement savings, and annual contribution (include employer match). Set your expected annual return and inflation rate. Then enter your desired annual income in retirement (in today's dollars) and your safe withdrawal rate. If you expect Social Security income, enter your estimated monthly benefit — the calculator subtracts that from the savings-funded income needed, reducing your required nest egg.

The retirement age calculator finds the year your projected portfolio balance reaches your target nest egg, using real (inflation-adjusted) returns so all figures stay in today's dollars. To model what happens once you retire, use the safe withdrawal rate calculator.

How Much Do You Need to Retire?

The standard formula: Nest Egg = (Desired Annual Income – Annual Social Security) ÷ Withdrawal Rate. Using the 4% rule with a $60,000/year goal and $20,000/year in Social Security:

Annual from savings = $60,000 – $20,000 = $40,000
Nest egg = $40,000 ÷ 0.04 = $1,000,000

Without Social Security: $60,000 ÷ 0.04 = $1,500,000. That $500,000 gap is why claiming SSA early vs. late matters — delaying to 70 can add $500–$1,000/month in benefits, meaningfully reducing the savings you need. Check your personalized estimate at ssa.gov/myaccount.

The Impact of Starting Early vs. Late

Compounding is the most powerful force in retirement planning — time matters more than rate of return. Consider two scenarios at 7% nominal return (4% real after 3% inflation):

Start at 25, contribute $6,000/year: By 65, accumulates approximately $1.28M. Retires at 65 on schedule.
Start at 35, contribute $6,000/year: By 65, accumulates approximately $567K. Needs to either work longer, contribute more, or accept less income.

The 10-year head start generates more than double the outcome, despite only $60,000 more in contributions. If you're behind, you have two levers: contribute more (use catch-up contributions after 50) or delay retirement by a few years — each additional year both adds savings and removes one year from the drawdown period.

Use our 401(k) calculator to model how employer matching and contribution increases accelerate your timeline.

Choosing the Right Withdrawal Rate

The withdrawal rate determines your nest egg target. The widely cited 4% rule was calibrated for 30-year retirements with a 60/40 stock-bond portfolio. But many people retire at 60 and live to 90 — a 30+ year horizon. Research suggests:

4.0% — historically sustainable for 30-year retirements (Trinity Study baseline)
3.5% — more conservative; better for 35+ year retirements or high-equity portfolios in volatile markets
3.0% — very conservative; appropriate if you plan for 40+ years or want a high margin of safety
5.0%+ — aggressive; portfolio depletion risk increases significantly, especially in bad sequence-of-returns scenarios

The right rate depends on your asset allocation, spending flexibility, and whether you have other income sources. If you can cut spending by 20% in a bad year, you can sustain a higher withdrawal rate.

Social Security Claiming Strategy

Social Security is one of the most consequential financial decisions of retirement, yet many people default to claiming early at 62 without analyzing the long-term cost. Your benefit grows by approximately 6–8% for each year you delay from FRA (Full Retirement Age) to 70. For someone with an FRA benefit of $2,500/month: claiming at 62 reduces it to ~$1,750; delaying to 70 increases it to ~$3,300 — a $1,550/month difference for life.

The break-even analysis: if you claim at 62 and receive $1,750/month, and your spouse or survivor would receive more by waiting until 70 (higher survivor benefit), the calculus changes for married couples. Health expectations matter too — if family history suggests longevity past 82, delaying is almost always financially superior. Use this retirement age calculator alongside our safe withdrawal rate calculator to model how delaying SS reduces the required portfolio withdrawal rate.
