How It Works

Reaching Financial Independence and Early Retirement comes down to one target number and the date you hit it. The projection here estimates your 'FIRE Number' — the nest egg you need to walk away from full-time work — and the year your portfolio is likely to reach it, with current market conditions and 2026 inflation built into the math. Seeing that date in concrete terms is what turns a vague goal into a plan you can actually act on.

The FIRE Number itself comes from a modified Safe Withdrawal Rate (SWR), often described as the '4%' rule: annual expenses divided by your chosen withdrawal rate give the portfolio size you're aiming for. From there, the model grows your savings year by year using your starting balance, monthly contributions, and an assumed annual investment return, stepping forward one year at a time until the balance crosses your FIRE Number.

Treat the result as a projection rather than a promise. Real-world returns swing from year to year and inflation rarely holds steady, so the single biggest pitfall is leaning on optimistic returns while quietly underestimating what you'll actually spend in retirement. Revisit the inputs as your situation changes, and build in a cushion for the down markets and surprise costs that history says are coming.

Example: Sarah's Path to FIRE

  1. 1 Sarah is 30 years old, has $50,000 in savings, and earns $80,000 annually. Her desired annual expenses in retirement are $50,000 (in today's dollars), and she saves $1,500 per month. She expects an average annual investment return of 7%.
  2. 2 Using the 4% Safe Withdrawal Rate, Sarah's FIRE Number is $50,000 / 0.04 = $1,250,000. The calculator then projects her savings growth: Year 1: $50,000 * 1.07 + $18,000 = $71,500. This process continues, factoring in her consistent $1,500 monthly contributions.
  3. 3 Based on these inputs, Sarah is projected to reach financial independence and retire early in 18 years, at the age of 48, in the year 2044. Her portfolio will have grown to approximately $1,250,000, allowing her to comfortably cover her $50,000 annual expenses.
  4. 4 This example highlights how consistent savings and reasonable investment returns can significantly accelerate your FIRE journey. Sarah's savings rate of 22.5% ($18,000 / $80,000) is a strong contributor to her early retirement projection. Adjusting her savings or investment returns would directly impact her FIRE date.

Frequently Asked Questions

What is the FIRE number and how do I calculate it?
Your FIRE number is your annual expenses multiplied by 25 (based on the 4% rule). If you spend $50,000 per year, your FIRE number is $1,250,000. Once your investments reach this amount, you can likely retire early.
What savings rate do I need for early retirement?
At a 50% savings rate, you can retire in roughly 17 years. At 60%, about 12.5 years. At 70%, about 8.5 years. The savings rate matters far more than investment returns for early retirement timelines.
Is the 4% rule still safe for early retirees?
The 4% rule was designed for 30-year retirements. Early retirees with 40-50 year horizons may want to use a more conservative 3.25-3.5% withdrawal rate or incorporate flexible spending strategies to reduce the risk of running out of money.
