How to Retire in 5 Years: Calculator + Final Sprint Plan
A 5-year retirement sprint is categorically different from a 10-year plan. With only 5 years of compounding ahead, investment returns contribute relatively little to portfolio growth — the math is dominated by how much you already have and how aggressively you save. The key threshold: at typical return assumptions, you need to have roughly 70–80% of your FI number already saved before the 5-year sprint begins. Below that, the required annual savings exceed what most high earners can realistically achieve. Above that, the final sprint is very achievable — and the Roth conversion ladder clock is your most urgent planning constraint.
Retire in 5 Years: Calculator
Enter your current situation. The calculator shows your FI number adjusted for your actual retirement horizon, your projected portfolio, the coverage ratio (how close you are), and what you need to save annually to close any remaining gap.
The 5-year FIRE equation: proximity is everything
In a 10-year FIRE plan, investment compounding does significant heavy lifting: $600K growing at 5% real for 10 years becomes $978K before you add a single contribution. In a 5-year sprint, the same $600K becomes only $766K. That's $212K less compounding — a gap that can only be closed by higher starting savings or higher annual contributions.
The practical implication: you need to already be close to your FI number. Arriving at a 5-year sprint with 50% of your FI number requires $90K–$170K/yr in additional savings depending on return assumptions — an unrealistic burden for most households. Arriving at 70–80% of FI with the same savings rate closes the gap comfortably.
Required annual savings: starting coverage vs. real return
The table below uses $75,000/yr retirement spending at a 3.5% SWR (40-year horizon, retire at ~52) = $2,142,857 FI number. Use the calculator above for your own scenario.
| Starting portfolio (% of FI) | Starting $ | Save/yr at 3% real | Save/yr at 5% real | Save/yr at 7% real |
|---|---|---|---|---|
| 50% of FI | $1,071,429 | $169,700 | $140,300 | $111,300 |
| 60% of FI | $1,285,714 | $122,900 | $90,800 | $59,100 |
| 70% of FI | $1,500,000 | $76,100 | $41,300 | $6,800 |
| 80% of FI | $1,714,286 | $29,200 | On track | On track |
| 90% of FI | $1,928,571 | On track | On track | On track |
FI number = $75,000 / 3.5% = $2,142,857. FV formula: FV = PV×(1+r)⁵ + PMT×((1+r)⁵−1)/r. "On track" means projected FV exceeds FI number at the stated return with the stated starting portfolio and $0 additional savings. Adjust your scenario using the calculator above.
The green rows illustrate the key threshold: at 80% of FI or better, a 5-year sprint is achievable at any plausible return assumption. At 70%, you need solid returns or meaningful annual savings. Below 60%, the math gets very hard — consider whether a 7- or 8-year horizon changes the picture dramatically (it usually does).
Roth conversion ladder: the most time-sensitive decision in a 5-year sprint
For early retirees who plan to live on pre-tax account withdrawals before age 59½, the Roth conversion ladder is the primary penalty-free bridge strategy. The critical constraint: each Roth conversion seasons for 5 years before the converted principal can be drawn penalty-free.
Here is what that timing means for a 5-year sprint:
- Conversions done in 2026 (this year) → penalty-free draws available starting in 2031 (year 1 of retirement)
- Conversions done in 2027 → available in 2032 (year 2 of retirement)
- Conversions done in 2028 → available in 2033 (year 3 of retirement)
If you skip conversions in 2026 and start in 2028, you arrive at retirement with a 2-year gap — years 1 and 2 of retirement have no Roth ladder income available. You'd need to bridge that gap from taxable brokerage, SEPP, or Roth contributions (which you can always withdraw penalty-free, without the 5-year seasoning requirement).
Pre-59½ access: match your bridge strategy to your retirement age
The 10% early withdrawal penalty is the main structural obstacle for FIRE planners retiring before 59½. How you solve it depends on when you plan to retire:
- Retire at 55 or later: Rule of 55 applies. Draw any amount from your most recent employer's 401(k) without penalty or fixed schedule. This is the simplest and most flexible bridge. Warning: rolling your 401(k) to an IRA before you've taken all the Rule-of-55 draws you need permanently eliminates the exception.
- Retire before 55: Rule of 55 does not apply. Your primary bridges are (1) taxable brokerage account — no age minimum, no penalty, often 0% federal tax on LTCG; and (2) the Roth conversion ladder described above. See taxable brokerage FIRE guide.
- 72(t) SEPP: Available at any age, but requires a fixed payment schedule for the longer of 5 years or until 59½. For most 5-year sprint retirement ages (45–54), this means a 5.5–14.5 year irrevocable commitment — too long for most plans. Use the SEPP calculator to confirm whether the income and commitment work for your situation.
Max contributions during the 5-year sprint
Every dollar you can shelter in tax-advantaged accounts reduces your taxable income during peak earning years and builds the Roth and pre-tax balances you'll need in retirement. With 2026 limits: 1
- 401(k)/403(b) basic deferral: $24,500/yr
- Catch-up contribution at ages 50–59: +$8,000/yr = $32,500 total
- Super catch-up at ages 60–63: +$11,250/yr = $35,750 total
- IRA / backdoor Roth IRA: $7,500/yr under 50; $8,600/yr at 50+ 1
- HSA (if on HDHP): $4,400/yr self-only; $8,750/yr family — triple tax advantage 2
- Mega backdoor Roth (if your plan allows after-tax contributions): up to $37,500+ into Roth annually
For a 5-year sprint, prioritize accounts that build your bridge — the taxable brokerage and Roth (via contributions and conversions) that you'll draw on before 59½. Pre-tax 401(k) dollars are useful for retirement but inaccessible without a bridge. A common 5-year sprint structure: max pre-tax 401(k) for the tax deduction, then direct surplus to taxable brokerage for the bridge, then start Roth conversions in the tax space you've opened by stopping work.
Sequence-of-returns risk in the final stretch
A major market drawdown in years 3–5 of your sprint can set back your retirement date by 2–3 years. A 30% market correction when you're at 85% of FI suddenly puts you at 60% — and the timeline math changes materially.
The classic hedge for pre-retirement investors approaching their target: the bond tent. In the final 2–3 years before retirement, gradually reduce equity allocation and hold 1–2 years of spending in stable assets (short-term bonds, I bonds, cash). After you retire, you can refill the tent by selling bonds while equities recover. This asymmetrically reduces sequence risk without sacrificing long-run returns. See sequence of returns risk guide and asset allocation for early retirees.
The "one more year" trap for 5-year planners
The most common FIRE trap is perpetually saying "I'll retire in 5 years" — for 10 consecutive years. If the calculator above shows you on track or close, the problem is usually not accumulation. It's the psychological gap between "I have enough" and "I feel like I have enough."
Common triggers that keep 5-year planners working longer than necessary:
- Using the wrong SWR. If you've been using the 4% rule for a 40-year horizon (should be 3.5%), your FI number is understated by 14% — and you keep thinking you're farther away than you are. Recalculate with the right horizon.
- Not modeling Social Security as a backstop. Even with 10 zero-earnings years, you will likely receive $800–$1,500/month at age 62 from your work history. Plan without it, but acknowledge it exists. SS timing for early retirees.
- Forgetting that Coast FIRE may apply. If your portfolio, with no additional contributions, grows to your FI number by 65, you may already be coast-FI — and the question is whether you want to retire now or keep saving for a higher spending floor. Coast FIRE calculator.
- Waiting for healthcare certainty. The ACA subsidy cliff is real, but manageable with planning. Healthcare before 65 covers every option — don't let coverage uncertainty delay a plan that is otherwise ready.
5-year FIRE mistakes to avoid
- Not starting Roth conversions in the accumulation phase. Many planners wait until they retire to start converting — which works fine for the 10-year plan, but creates a 2–5 year gap in the Roth ladder for 5-year sprinters. Start this year.
- Rolling the 401(k) to an IRA before Rule of 55 draws. If you retire at 55+ and need bridge income, a premature IRA rollover destroys the Rule of 55 exception retroactively. Draw first, roll the remainder later.
- Ignoring the transition-year MAGI spike. If you retire in mid-2031 with 6 months of W-2 income, your partial-year salary may push MAGI above the ACA cliff — costing $10,000–$20,000 in lost subsidies. Model it now. First year of early retirement guide.
- Building a 5-year plan that requires exactly median returns. Run the Monte Carlo simulator and target 85%+ success probability, not 50%. Markets are unpredictable in any 5-year window.
