📊 What Rate of Return Is Needed to Achieve Early Retirement?
---
1. Why Investment Return Matters — But Not Most- Savings rate outweighs ROI in the short term
Networthify's early-retirement calculator shows that to retire in 5–10 years, what matters most isn't your return—but how much you save each year.
- Suggested saving ranges
FIRE followers aim to save 50–75% of income, investing that into the market. With compounded returns, this accelerates your path to early retirement.
---
2. Typical Investment Return Expectations- Nominal returns (before inflation) on diversified portfolios (stock + bond) have averaged 7–10%, e.g., S&P 500 ~9–10%, but that needs adjustment.
- Real returns (after inflation & fees) usually range around 4–6%:
– Reddit discussion concludes that 4–5% is more realistic than overly optimistic 7%+.
– An assumption of 5% real return is common in FIRE planning.
---
3. The 4% Rule & Withdrawal Rate- 4% initial withdrawal rule: Traditionally allows you to withdraw 4% of your portfolio in the first retirement year and adjust for inflation, applicable for ~30-year retirements.
- For early retirees (50+ year horizon):
Vanguard's research shows success probability drops from ~82% (30-year) to ~36% (50-year).
Therefore, many FIRE advocates prefer a 3–3.5% withdrawal rate, implying a need for larger savings.

4. Blueprint: ROI + Savings = Retirement Timeline- Savings % vs Years to FIRE (assuming 5% return, 4% withdrawal):
- 10% savings → ~51 years to retire
- 40% savings → ~22 years
- Examples:
- With 5% real ROI, to hit a portfolio after which 4% withdrawal meets expenses, you'll likely need 25× annual expenses.
- Alternatively, a 6% actual return allows more growth, speeding FIRE—but long-term consistency matters most.
---
5. Suggested "Sweet-Spot" for Most People- Savings rate: 50–70% of income, to accelerate path to FIRE.
- Long-term real return expectations: 4–6% annually, with 5% as a conservative planning assumption.
- Withdrawal rate:
- 4% for shorter retirements (~30 years)
- 3–3.5% for very early retirees (~40–50 years).

6. Practical FIRE Strategy Template
1. Define your annual spending in retirement (e.g., $50k).
2. Choose withdrawal rate: 3.5–4%.
3. Calculate FIRE Number: expenses ÷ withdrawal rate × 25–28.
4. Estimate time to reach FIRE: using current savings rate & expected ROI (5%).
5. Use tools: Try calculators that adjust for your savings %, ROI, and withdrawal assumptions.
