Fidelity’s retirement benchmark calls for roughly 8x salary saved by age 60. A couple earning around $100,000 a year should ideally have at least $850,000 saved by the time they’re 59. But if they stop working at 59½, how far will that nest egg actually stretch?
Start with the updated Bengen framework. A 3.7% to 4.0% starting withdrawal rate on $850,000 produces roughly $31,000 to $34,000 in year-one income, with annual inflation adjustments thereafter. That math assumes a balanced portfolio and a 30-year horizon, both of which apply to someone retiring at 59.
Practitioners disagree on the safe number. Suze Orman caps it at 3%. Dave Ramsey defends 8%, a figure most planners reject. Princeton’s Wade Pfau has argued 2% to 3% may be more defensible given current valuations and bond yields. The practical middle ground for most retirees with a diversified portfolio sits in the 3.5% to 4.0% range.
At a 3.7% rate, the $850,000 portfolio delivers roughly $2,600 to $2,800 per month in the early years, before any Social Security check arrives. That is enough to cover modest essentials, but not the full cost of most households.
Why Social Security Timing Matters
One of the biggest levers this couple can pull is choosing their Social Security claiming age. Benefits fall up to 30% if claimed at 62 and rise about 8% per year of delay up to age 70. The 2026 cost-of-living adjustment came in at 2.8%, and COLAs compound on whatever base benefit is locked in at claiming, so a larger base means every future COLA adds more dollars.
A household earning around $100,000 typically sees a combined Social Security benefit in the $45,000 to $55,000 range at full retirement age. Delaying the higher earner to 70 while the lower earner claims earlier is the winning strategy for most married couples. The logic is straightforward: the larger benefit also becomes the survivor benefit, providing a meaningful income floor for whoever lives longer.
Building an Income Floor
Advisors consistently recommend that couples cover essential expenses (housing, food, insurance, healthcare) with guaranteed income sources and let the portfolio fund discretionary spending on top. The Bureau of Labor Statistics pegged average annual household spending at $78,535 in 2024, a practical baseline for what needs to be covered reliably.
- Bridge years from 59 to claiming age. Build a short Treasury ladder to cover the gap. As of mid-2026, the 2-year Treasury yields roughly 3.9%, the 5-year about 4.0%, and the 10-year around 4.6%, giving retirees meaningful real return on short-to-medium rungs with no credit risk.
- Defer the higher Social Security benefit. Every year of delay between full retirement age and 70 raises the lifetime check by roughly 8%, and all future COLAs apply to that larger base. A decade of higher payments can more than offset the years without a check.
- Run guardrails on the portfolio. Raise spending modestly after strong years and trim 10% in down years. This converts a static 3.7% rule into a flexible system that responds to actual market conditions rather than ignoring them.
- Avoid early withdrawals from pre-tax accounts. Pulling traditional retirement money before 59½ triggers a 10% federal penalty plus ordinary income tax. At 59½, that penalty disappears, but the ordinary income tax still applies, making withdrawal timing and account sequencing worth careful planning.
A reasonable monthly income target for this couple: about $2,700 from the portfolio during the bridge years, climbing to roughly $6,500 to $7,500 combined once both Social Security checks are flowing. The 2026 standard deduction for married filing jointly is $32,200, which shelters a meaningful portion of that income from federal tax. Couples where at least one spouse is 65 or older also benefit from a new $6,000 additional deduction per qualifying individual available for tax years 2025 through 2028, a provision introduced under the One Big Beautiful Bill Act that can further reduce taxable income in the early retirement years.
Two Decisions That Matter Most
First, decide which spouse delays Social Security and to what age. That single choice can swing lifetime household income by six figures and determines the size of the survivor benefit that protects the remaining spouse. Running the numbers for multiple claiming scenarios, typically using a break-even analysis around age 80 to 82, is worth the time.
Second, segment the $850,000 into two distinct buckets: a three-to-five-year ladder of Treasuries or high-yield savings covering essential expenses, and a growth portfolio (60/40 or 70/30) for the rest. A common mistake at this stage is going all-conservative because retirement feels close. With a 30-year planning horizon to age 90, inflation remains a larger long-run threat than near-term market volatility. Keeping a growth allocation intact while the Social Security bridge is funded by safe assets protects purchasing power over decades, not just years. For couples at 59 who have not yet maximized savings, it is worth noting that turning 60 opens the SECURE 2.0 super catch-up window: workers aged 60 to 63 can contribute up to $35,750 to a 401(k) in 2026, the highest limit ever available for that age group.
