Saving is the piece of retirement that most Americans have figured out. You settle on a percentage, set up automatic contributions, and let time do the rest over four decades. Spending, on the other hand, is the piece that hardly anyone thinks through in advance. Nearly half of all retirees reach retirement age with a nest egg but no written game plan for converting those savings into a steady stream of income. The net effect is a cohort of people who executed the accumulation phase beautifully and then winged it on the very step that decides whether their money actually outlasts them.
The stakes are not small. According to Northwestern Mutual’s 2025 Planning & Progress Study, 51% of Americans think it is somewhat or very likely they will outlive their savings, and 35% have taken no steps to address that risk. Those two figures describe the same problem from two angles: people know the danger and have not built a plan to manage it.
What a Written Plan Actually Contains
A spending plan is a set of rules that answers four questions: how much comes out of the portfolio each year, when Social Security starts, how healthcare gets paid, and how taxes are managed across account types. Each question has a defensible answer grounded in current data.
Start with the withdrawal rate. The classic benchmark is 4% of the starting balance, adjusted annually for inflation. On a $500,000 portfolio, that is $20,000 in year one, or roughly $1,667 a month. Whether that holds up depends on returns and inflation. The Federal Reserve’s preferred inflation gauge, core PCE, rose 0.1% month over month in June 2026 to an index reading of 130.27, and the 10-year Treasury yield sits at 4.71%. Fixed income can carry more of the load than it did five years ago, which changes the math on how aggressive the equity allocation needs to be.
Social Security Anchors Retirement Income
According to Stanford’s research on the program, Social Security covers roughly 40% of what the average retiree earned before stepping away from work. But the age you start claiming shifts that replacement rate in a meaningful way. File early, and your benefit gets clipped by about 6.7% for every year you take it before reaching full retirement age. Wait, and you earn roughly an 8% bump for each year you delay, all the way up to 70. In dollar terms, someone who would receive $2,000 at age 67 ends up with about $1,400 if they claim at 62, or roughly $2,480 if they hold off until 70.
The 2027 cost‑of‑living adjustment is currently tracking at 3.1%, based on one of the three months in the third quarter that the government uses to calculate the increase. That number matters more than most people realize. Social Security is the only major source of retirement income that automatically keeps up with inflation year after year. Your portfolio withdrawals do not get that same built‑in raise.
Healthcare Belongs as a Dedicated Line Item
Medicare covers a lot, but not everything, and the fixed costs are rising. The standard Medicare Part B premium is $202.90 a month in 2026, up from $185.00 in 2025. The Part A inpatient hospital deductible is $1,736 per benefit period. Higher earners pay income-related surcharges on top of that, which means Roth conversions and capital-gains timing can affect Medicare costs years later.
Match Spending Categories to Income Sources
Bureau of Economic Analysis data shows where retiree-heavy categories actually land. In June 2026, housing accounted for $3,955.9 billion in annual consumer spending, and healthcare for $3,741 billion, the two largest service categories. The Consumer Expenditure Survey put average annual household expenditures at $78,535 in 2024. A workable plan pairs predictable expenses (housing, insurance, groceries) with predictable income (Social Security, pensions, bond ladders) and leaves the portfolio to cover the variable line items.
Three Actions That Turn Savings Into a Paycheck
- Write down a target withdrawal rate and the dollar amount it produces. If the portfolio is $600,000, a 4% rate is $24,000 a year. Revisit the number annually rather than monthly.
- Decide the Social Security claiming age in advance. Delaying from 67 to 70 raises the benefit by roughly 24%, and that increase applies for life.
- Build a two-year cash buffer in short-duration instruments. The FDIC national average 12-month CD yield is 1.71%, though top online banks pay several times that. The point of the buffer is to avoid forced sales during a down market.
The personal saving rate has fallen to 2.8% in the second quarter of 2026, down from 6.2% in the first quarter of 2024, which means new retirees are drawing down into a household economy already leaning harder on income than on savings. A written plan changes whether the retiree is the one making decisions when the market moves (the mix, the payment calendar, and the withdrawal order are all laid out in our free guide on turning savings into a monthly paycheck).
