The 25× rule at 55 — and when to nudge it to 28×
The 4% rule says you can safely withdraw 4% of your portfolio in year one of retirement and adjust for inflation each year after. Flip it: save 25 times your annual expenses. On €30,000/yr of spending that's a €750,000 target.
Retire at 55 and your money may need to last 35–40 years rather than the 30 years Bengen tested. Historically that drops the safe withdrawal rate to about 3.5%, which means a 28× target — €840,000 on €30,000/yr. Use the calculator above to test both: enter your target age as 55 and either bump monthly expenses up ~12% or drag the nest-egg target field directly.
Target 25× annual expenses for a baseline retirement at 55, or 28× (€840K on €30K/yr of spending) for a 35-year-plus drawdown buffer.
The Rule of 55: penalty-free 401(k) access (US)
The IRS Rule of 55 is a quiet superpower for US early retirees. If you separate from your employer in the calendar year you turn 55 or later, you can withdraw from that employer's 401(k) without the 10% early-withdrawal penalty. You still pay ordinary income tax, but the penalty is gone.
- It only covers the 401(k) of the employer you just left. Old 401(k)s from prior jobs and all IRAs are excluded.
- Consolidate before you leave: roll older 401(k)s into your current employer's plan (if it accepts roll-ins) so the whole balance qualifies.
- Do not roll the 401(k) to an IRA after separation if you plan to use the Rule of 55 — once it's an IRA, the penalty reappears until 59½.
- Public safety workers get the same treatment at age 50.
If you leave your employer at 55+ and keep the money in that 401(k), you can withdraw penalty-free for the 4.5 years until 59½ — saving you 10% versus an IRA.
Early pension access in Europe at 55
Europe doesn't have the Rule of 55, but most countries let you access pillar-2 and pillar-3 pensions before state-pension age — usually with a permanent reduction:
- Germany: Riester and Rürup can pay from 60–62 in most contracts. State pension early-claim before 67 typically costs 0.3%/month (~3.6%/yr) for life.
- France: Retraite anticipée pour carrière longue from 58–60 if you started working before 20. Otherwise the legal age is 64 with reductions before full rate.
- Netherlands: Most pillar-2 schemes allow retirement from 55, with the payout actuarially reduced — often 30–40% lower than waiting to AOW age.
- UK: Personal pensions and SIPPs are accessible from 55 (rising to 57 in April 2028). 25% tax-free lump sum, the rest taxed as income.
Most EU pillar-2/3 pensions open at 55–60 with a 5–8%/year permanent reduction for early claims — plan to live mainly off taxable savings until those payments justify themselves.
Healthcare from 55 to 65
Ten years of private cover is the bridge nobody plans for. Real-world monthly premiums per adult, no children:
- US ACA (silver plan, no subsidy): $900–$1,600/month at 55–64.
- Germany (PKV after 55): €600–€1,100/month.
- UK private (Bupa/AXA): £250–£500/month.
- Spain/Portugal: €80–€200/month — significantly cheaper for active expats.
Take your number, add it to monthly expenses in the calculator, and watch the nest-egg target update. €1,000/month of extra expenses lifts the target by €300,000.
Budget €600–€1,200/month per adult for healthcare from 55 to 65 — €72,000–€144,000 over the decade, or €100,000–€200,000 in extra nest-egg target.
Catch-up contributions: the last 5 years matter a lot
From age 50 the US lets you bolt extra contributions onto every tax-advantaged account: an extra $7,500/yr to 401(k)s and $1,000/yr to IRAs (2026 limits). From 60–63 the SECURE 2.0 'super catch-up' bumps the 401(k) extra to roughly $11,250.
Run the math: maxing the catch-ups from 50–55 is $42,500 of extra principal over 5 years. At 7% real returns that compounds to about $50,000–$55,000 by 55 — and meaningfully more if you keep working to 60.
Maxing the 50+ catch-up contributions for the 5 years before 55 adds roughly $50,000 to your retirement balance — directly subtractable from your gap.
