How to Use This Calculator
Enter your Current Age (e.g. 32 in years), Target Early Retirement Age (e.g. 45 in years), Current Net Worth / Savings (e.g. 200000 in ), Annual Savings Amount (e.g. 50000 in /year), Expected Annual Investment Return (e.g. 8.0 in %), and Annual Spending in Retirement (e.g. 60000 in /year).

The Formula
FIRE Number = Annual Retirement Spending × 25 (4% Withdrawal Rate Rule)
Projected Net Worth = Current NW × (1+r)^n + Annual Savings × [(1+r)^n - 1] / r
Worked Example
Age 32, targeting retirement at 45, 200K net worth, 50K/year savings, 8% return, 60K/year spending.
- FIRE Number: 60,000 × 25 = 1,500,
000.
- Projected Net Worth at Age 45 (13 years): ≈ 1,475,
000.
- Status: Nearly FIRE Ready — 1-2 more years needed.
Understanding Your Result
The 4% rule (withdraw 4% of your portfolio in year one, then adjust for inflation annually) has historically sustained a 30-year retirement with a 95% success rate on a 60/40 portfolio. RMDs (Required Minimum Distributions) begin at age 73 under the SECURE 2.0 Act and are calculated annually as account balance ÷ IRS life expectancy factor. Missing an RMD triggers a 25% excise tax on the amount not distributed (reduced to 10% if corrected promptly).
💡 Financial Planning: Expert Principles & Risk Awareness
- All calculations assume fixed rates and idealized conditions. Real-world results vary due to market volatility, inflation, fees, and taxes.
- The Consumer Financial Protection Bureau (CFPB) recommends consulting a certified financial planner (CFP) for decisions involving significant sums.
- Run at least three scenarios: optimistic, pessimistic, and most-likely — to understand the full range of potential outcomes before committing.
- Inflation averages 2–3% annually in the US (Federal Reserve target). Long-term projections that ignore inflation significantly overstate future purchasing power.
- Tax treatment varies widely by account type (IRA, 401k, brokerage), jurisdiction, and income level. Verify tax implications with a CPA before acting.
- Compound interest works for you in savings/investments and against you in debt. The difference of even 1% in rate, sustained over decades, is enormous.
- Emergency funds (3–6 months of expenses) should be established before optimizing for returns — financial security precedes financial growth.
- Financial projections older than 12 months should be recalculated. Interest rates, tax brackets, and market conditions shift materially year to year.
