Understanding Your Retirement Timeline

The 4% Rule

The most widely-used retirement planning guideline: withdraw 4% of your portfolio in year one, then adjust for inflation. This means you need roughly 25x your annual expenses saved. A $60,000/year lifestyle needs ~$1.5M in savings (excluding Social Security and pensions).

The Power of Starting Early

Compound interest is exponential. $500/month starting at age 25 grows to ~$1.4M by 65 (at 7% returns). Start at 35 and you get ~$680K — less than half. Every year you delay costs you thousands in lost compounding.

Key Milestone Ages

50: Catch-up contributions allowed. 55: Rule of 55 for 401(k) access. 59.5: Penalty-free IRA withdrawals. 62: Earliest Social Security. 65: Medicare eligibility. 67: Full SS retirement age. 70: Maximum SS benefit.

Inflation: The Silent Thief

At 3% inflation, $5,000/month today becomes $8,100/month in 15 years and $13,100/month in 30 years. Your retirement plan must account for this. Our calculator uses real (inflation-adjusted) returns to give you an accurate picture.

Frequently Asked Questions

How do I know when I can retire?

You can retire when your investment portfolio and guaranteed income sources (Social Security, pensions) can cover your annual expenses indefinitely. A common rule of thumb is the 4% rule: you need 25x your annual expenses saved. For example, if you need $60,000/year and expect $24,000 from Social Security, you need to cover a $36,000 gap — requiring about $900,000 in savings.

What is the 4% rule for retirement?

The 4% rule states you can withdraw 4% of your portfolio in the first year of retirement, then adjust for inflation each year, with a high probability your money lasts 30+ years. This means you need approximately 25 times your annual withdrawal amount saved.

Can I retire at 55?

Retiring at 55 is possible but requires more savings since you'll fund a longer retirement (35-40 years) without Social Security or Medicare until 62 and 65. You'll need to bridge healthcare costs and may use the Rule of 55 for 401(k) access or Roth IRA contributions for penalty-free withdrawals.

How much do I need to save each month to retire by 65?

It depends on your current age, savings, expected returns, and target income. A 30-year-old with $50,000 saved needs about $800-$1,200/month to retire at 65 with a $60,000/year lifestyle (assuming 7% returns and $24,000/year Social Security). Use our calculator above for a personalized estimate.

What is FIRE (Financial Independence, Retire Early)?

FIRE stands for Financial Independence, Retire Early — a movement focused on aggressive saving (50-70% of income) and investing to achieve financial independence decades before 65. Variations include Lean FIRE (~$40k/year), Fat FIRE ($100k+/year), and Barista FIRE (partial retirement with part-time work).

How does inflation affect my retirement timeline?

Inflation erodes purchasing power over time. At 3% annual inflation, $60,000 today requires about $97,000 in 15 years to maintain the same lifestyle. Our calculator factors in inflation to give you projections in both today's and future dollars.
