Can I Retire at 70?

How much do you need to retire at 70?

A 70-year-old planning to age 90 has a 20-year retirement horizon. On a 20-year horizon, historical data shows the 4.5% withdrawal rate succeeds in over 95% of rolling historical periods at a 60/40 allocation; the 4.0% rate succeeds in over 98%.¹ That makes 70 the most permissive starting withdrawal age in the decade from 60 to 70 — a shorter horizon means a given portfolio can support a larger annual draw with the same historical confidence level.

But the math at 70 isn't as favorable as the SWR table suggests in isolation, because Social Security is typically at its maximum already in the income stack. A couple with combined SS income of $80,000–$120,000/year drawing from a $3M portfolio is already spending only $30,000–$60,000 from the portfolio — a 1.0–2.0% effective draw rate — which is essentially permanent regardless of sequence. The real risks at 70 are not portfolio depletion but IRMAA escalation from large RMDs, estate exposure from a growing traditional IRA, and long-term care tail risk.

Social Security at 70: the decision is settled

The Social Security claiming debate that dominates retirement planning in the 62–69 window no longer exists at 70. You've already locked in the maximum possible benefit: 124% of your Full Retirement Age amount for anyone born in 1960 or later (FRA = 67), or the equivalent maximum for earlier birth years. No additional delayed retirement credits accrue past age 70.²

The SS tax picture at 70 matters more than most retirees realize. Once your combined income (MAGI + ½ of SS benefits) exceeds $44,000 MFJ, up to 85% of your SS benefit becomes taxable ordinary income.³ For a couple with $5,000 + $4,000/month combined SS ($108,000/year), 85% of that — $91,800 — enters your taxable income before portfolio distributions. A Roth conversion that adds $100,000 of income on top of that can push you deep into the 24% or 32% bracket, plus higher IRMAA tiers two years later.

Medicare at 70: 5 years in, IRMAA on fixed income

At 70, Medicare is established and continuous. There's no gap, no COBRA bridge, no ACA cliff to manage. The healthcare math has largely simplified from a gap-funding problem to an annual cost-management problem.

What does require active management is IRMAA — the income-related Medicare premium surcharge based on MAGI from two years prior.⁴ Unlike during your working years, when high income from compensation drove IRMAA, the levers at 70 are entirely within your control: how much you Roth-convert each year, how much of your taxable-account gains you realize, and what your RMDs will be in 3–5 years.

The IRMAA management challenge at 70 is that your income floor is relatively high and not entirely controllable: SS income is fixed and largely taxable, RMDs will begin soon and are non-optional, and even moderate Roth conversion amounts push MAGI upward. The planning task is to set Roth conversion targets that maximize long-term tax reduction without triggering IRMAA tier-jumps that cost more in the near term than they save over the conversion horizon.

The Roth conversion window: your most urgent financial priority

For a 70-year-old, the Roth conversion window is narrow and closing. RMD start age depends on birth year:

• Born 1951–1959: RMDs began at age 73 — if you're 70 today in 2026, you were born in 1956 and your RMDs begin in 3 years (age 73).
• Born 1960 or later: RMDs begin at age 75 — a 70-year-old born in 1960 has 5 years of Roth conversion runway before mandatory distributions begin.

Once RMDs begin, they consume your low-bracket room. A $3M traditional IRA at age 70 — growing at 6%/year without any conversions — reaches approximately $4.3M by age 75. First-year RMDs from $4.3M at the Uniform Lifetime Table divisor for age 75 (27.4) = $157,000. Add $62,000–$80,000 in SS income (85% taxable = $53,000–$68,000 taxable SS) and you're at $210,000–$225,000 of ordinary income before any portfolio distributions — firmly in the 32–35% bracket, with IRMAA Tier 2–3 on top.

Key guardrails for Roth conversions at 70:

• SS provisional income: Converting even $50,000 at 70 can push combined income above $44,000 MFJ, making 85% of SS benefits taxable — effectively raising the tax cost on the conversion. If you're already over the $44,000 threshold (most $2M+ retirees are), the additional SS taxation is already baked in and doesn't change the conversion cost calculation at the margin.
• IRMAA 2-year lag: Conversions in 2026 set 2028 Medicare premiums. A $150,000 conversion that pushes MAGI from $210,000 to $360,000 triggers the Tier 3 IRMAA surcharge in 2028 ($7,800/yr for the couple). Whether that surcharge cost is worth paying depends on the present-value of future RMD tax savings — model it explicitly.
• QCDs at 70½: Once you turn 70½, Qualified Charitable Distributions of up to $111,000/year from a traditional IRA can satisfy RMDs and are excluded entirely from gross income — no IRMAA impact, no SS provisional income effect. This is often more efficient than a charitable deduction for donors at this wealth tier.⁵
• Roth 401(k) no-RMD rule: If you have a Roth 401(k), it is not subject to lifetime RMDs starting in 2024 (SECURE 2.0 §325). A Roth 401(k) balance does not need to be rolled to an IRA to avoid RMDs anymore — but rolling it may still simplify account management.

Retirement calculator: year-by-year projection from age 70

RMDs begin soon: the urgency table

The following shows how a traditional IRA growing at 6%/year without conversions produces first-year RMDs, and how many years of Roth conversion runway remain for a 70-year-old depending on birth year:

ULT divisor at age 73: 26.5; at age 75: 27.4. (The divisor increases slightly between 73 and 75 — the table adjusts for this.) Note that even the first-year RMD figure grows as the account grows, and rises each subsequent year as the divisor decreases while the account balance compounds. A $5M IRA that throws off $244K in year-1 RMDs at age 75 will generate $285K–$320K by age 80 absent significant Roth conversions.

Five planning priorities at 70

1. Execute the Roth conversion plan now — the window is 3–5 years at most. If you were born 1956–1959, RMDs begin at age 73: you have 3 years. If born 1960+, you have 5 years to age 75. This is not a planning horizon you can push off — each year of inaction means a larger traditional IRA, larger future RMDs, and fewer low-bracket years to work with. The right annual conversion target is the one that fills the 22% or 24% bracket without triggering IRMAA tier jumps that cost more in the near term than the conversions save long-term. A fee-only planner can model this in a single session; it's one of the highest-return planning exercises for $2M–$10M retirees at this stage.
2. Integrate QCDs into your giving strategy the moment you turn 70½. Once you're 70½, Qualified Charitable Distributions of up to $111,000/year from a traditional IRA can satisfy part or all of your RMDs and are excluded entirely from your gross income — no MAGI impact, no SS provisional income effect, no IRMAA trickle. For charitably inclined households at this wealth tier, QCDs are almost always more tax-efficient than itemizing deductions for cash gifts. If you're doing large Roth conversions and also giving significantly to charity, shifting some of the giving to QCDs can preserve Roth conversion room that cash donations would otherwise consume.
3. IRMAA management is a 2-year chess game, not an annual decision. Every income decision in 2026 sets 2028 Medicare premiums. Every decision in 2027 sets 2029 premiums. With SS income largely fixed and RMDs arriving in 3–5 years, your main variables are Roth conversion size, capital-gain realization timing, and QCD volume. Map the next 3–5 years explicitly: what's your projected MAGI each year, which IRMAA tier does it fall in, and how much does each tier cost the couple per year? The difference between Tier 1 and Tier 3 IRMAA is $5,851/year for a couple — meaningful against a relatively small marginal tax saving on a conversion that crossed the tier boundary.
4. Estate planning is at its most urgent for estates approaching $15M. The OBBBA (July 2025) made the $15M federal estate and gift exemption permanent.⁶ For a household with $5M–$10M in assets growing at 6%/year for 20 more years, the portfolio could reach $16M–$32M — crossing into estate-taxable territory. Roth conversions reduce traditional IRA balances now (shrinking the gross estate), GRAT and SLAT structures can transfer appreciation outside the estate, and QCDs reduce the estate's size by distributing assets to charity. At 70, your estate-planning window is open but the compounding clock is running. OBBBA also preserved the §1031 exchange and reinstated 100% bonus depreciation permanently — if you hold real estate or business assets, the estate planning opportunities at this stage are broader than they appear.
5. Long-term care contingency planning is not optional at 70. A 70-year-old healthy couple has roughly a 70% probability that at least one partner will need some form of long-term care during retirement. At $5M+ in assets, the traditional LTC self-insurance approach is financially viable for moderate care needs ($3,000–$6,000/month), but 3–5 years of full-time memory care at $12,000–$15,000/month represents $432,000–$900,000 in spending that compounds into estate depletion. Hybrid life/LTC policies remain available at 70 but are significantly more expensive and harder to underwrite than at 65 — if you haven't addressed LTC yet, this is the last practical window for most households.

Checklist: planning priorities for retiring at 70 with $2M–$10M

• ✓ Confirm SS claiming is in payment at the maximum rate — no additional delayed credits accrue past age 70, and no retroactive catch-up is available if SS was delayed past 70
• ✓ Establish Roth conversion plan immediately: annual target, bracket cap (fill to 24% without IRMAA tier jump), years remaining (73 or 75 depending on birth year)
• ✓ Calculate first-year RMD at age 73 or 75 from current IRA balance — this sets the urgency for conversions and the IRMAA tier your MAGI will reach in those years if you do nothing
• ✓ QCD strategy in place for any charitable giving once you turn 70½ — eliminates the MAGI impact vs. cash donations on the same gift
• ✓ IRMAA calendar modeled 3 years forward: 2026 income → 2028 premiums, 2027 income → 2029 premiums, first RMD year → IRMAA impact starting 2 years later
• ✓ Estate plan reviewed: beneficiary designations on all accounts current; trust structure appropriate for your estate size relative to $15M OBBBA exemption
• ✓ Long-term care contingency addressed: self-insure assessment, hybrid LTC review if not already in force, or documented family plan for care coordination
• ✓ Portfolio asset allocation reviewed for distribution phase — accumulation-phase equity concentration may be appropriate to dial back when sequence-of-returns risk matters more than maximum growth
• ✓ QLAC evaluated: a Qualifying Longevity Annuity Contract of up to $210,000 can defer up to that amount of IRA balance from RMD calculation until age 85, providing longevity insurance and reducing near-term RMDs⁵
• ✓ Part D drug plan reviewed annually — formularies change each year; reviewing at medicare.gov during open enrollment (Oct 15 – Dec 7) can save $600–$2,000/year
• ✓ Medigap or Medicare Advantage confirmed appropriate — at 70, your healthcare utilization pattern is clearer than at 65; review whether your current plan structure still matches your actual usage

Get matched with a fee-only retirement planning specialist

Retiring at 70 looks simple from the outside — the hard decisions are behind you, income is running, the portfolio is at its peak. The complexity is in the remaining window: 3–5 years of Roth conversions before RMDs close off the low brackets, a 2-year IRMAA lag that turns every income decision into a 2-year chain of Medicare-cost consequences, and a Qualified Charitable Distribution strategy that can eliminate MAGI entirely for giving you were going to do anyway. Fee-only advisors who specialize in retirement distribution planning build the multi-year income calendar that ties these together — typically recovering their fee in avoided taxes within the first year of engagement.

William Bengen's SAFEMAX research (1994) and the Trinity Study (Cooley, Hubbard & Walz, 1998) established safe withdrawal rates for 30-year retirements at 60/40 allocations. On a 20-year horizon (age 70 to 90), the 4.5% withdrawal rate has succeeded in over 95% of rolling historical periods at a 60/40 allocation; the 4.0% rate succeeds in over 98%; the 5.0% rate in approximately 88%.

Delayed retirement credits accrue at 8%/year for each year SS is deferred past FRA, up to age 70. Maximum delayed retirement credit: 24% of FRA benefit for a 3-year delay (FRA 67 to age 70). No additional credits accrue for claiming past age 70. 2026 maximum SS benefit: $4,152/month at FRA (67); $5,181/month at age 70 (124% × $4,152). SS at age 62 for born-1960+: 70% of FRA = approximately $2,906/month at maximum earnings.
