An Expense Tracker for Recent Retirees: What to Track

The first 12 months of retirement are the months a household discovers that the spending plan they assembled at age 64 was wrong in the same direction every time. In EBRI's 2024 Spending in Retirement Survey, half of retirees said overall expenses came in higher than they expected, and 31% said spending was higher than they could afford — up from 17% in 2020.^[] The Bureau of Labor Statistics puts average annual expenditures for households age 65+ at $61,432 in 2024,^[] but the all-65+ average flattens out a sharp early-retirement pattern. An expense tracker for recent retirees needs to surface that pattern, not smooth it.

The piece most retirees miss in month 1 is not the dollar total. It's that the cash flow has reorganized itself.

Why year-one spending diverges from the plan

Most pre-retirement budgeting tools were calibrated against a working couple's W-2 cycle. Retirement breaks all three of its assumptions at once: predictable income, fixed payroll deductions, and a stable category mix. The day both spouses enroll in Medicare at 65, the single line on a working pay stub for "employee share of family health premium" splits into six separate debits across Part B, Part D, and supplemental coverage. The 2026 standard Part B premium is $202.90 per person per month with a $283 annual deductible.^[] A couple covering both spouses on Original Medicare with a typical Plan G supplement and a Part D plan is now paying around $9,800 in annual premiums alone — before any out-of-pocket. Fidelity's 2024 estimate of $12,850 in first-year healthcare spend for a couple at 65^[] is consistent with that floor plus the deductible and a thin coinsurance layer.

That total isn't surprising. What surprises retirees is the cash visibility of it: Part B is auto-deducted from each spouse's Social Security check (invisible to a checking-account view), while Medigap and Part D are direct-billed to checking each month (visible). An expense tracker that only sees the bank statement understates retiree healthcare by the SSA-deducted portion — roughly half of the total. The household sees an unfamiliar number and, more dangerously, doesn't see another one at all.

The categories that grow in the first 12 months

Three lines reliably ratchet up in the first year. Healthcare is the big one and the most documented. Travel and leisure is the second; over a third of the EBRI 2024 sample reported travel and entertainment higher than expected.^[] The third is home maintenance — projects deferred during working years tend to land in the first 24 months of retirement, when the household has time and reason to address them.

The travel uplift is the so-called "go-go years" effect, popularized in David Blanchett's research on the retirement spending smile. Average real spending falls about 26% from initial retirement to roughly age 84 before climbing again on healthcare,^[] but the curve doesn't apply uniformly — the first three to five years skew up on discretionary before the longer decline begins. A monthly drift flag on a discretionary category catches the trend while it's still optional.

The categories that shrink — and where the saving is smaller than expected

Commuting, work clothes, lunches, and 401(k) payroll deductions all drop. The combined relief is real but smaller than most pre-retirement projections assume. Transportation as a share of spending for households age 65+ stays stubborn; the BLS 2024 data has it near 17% of total annual expenditures for the over-65 group.^[] The car payments don't necessarily go away when the commute does, and insurance and fuel for non-work miles still scale with usage. Payroll-deduction relief is also smaller than the gross W-2 line suggested, because the working budget was already living on the net check, not the gross.

A useful exercise in month 3 is to pull the prior-year January and the post-retirement January side-by-side at the category level. The deltas often reveal that the categories the household assumed would drop didn't drop, and the categories nobody pre-assigned a number to (Medicare premiums, supplemental insurance, OTC medications) showed up at substantial dollar amounts.

What MFFT's expense tracker for recent retirees surfaces

The MFFT model is built around category-level monthly spend versus targets, with anomaly flags and a recurring-subscription audit. For recent retirees, that combination does three useful things at once:

• It treats SSA-deducted Part B as a healthcare line, not as a Social Security reduction, so the household's healthcare total reflects the real dollar amount.
• The recurring-subscription audit catches the long tail of small monthly debits — streaming services, magazine renewals, telehealth platforms, supplement subscriptions — that a working budget tolerated as a rounding error and a retirement budget shouldn't.
• The anomaly flag on a category catches the year-1 ratchets early. A 15% drift on the discretionary line in months 4 through 6 becomes visible while it's still a course correction.

If the household just left the pre-retirement category list MFFT recommends in the budgeting-app categories for the 24 months before Medicare, the post-retirement tracker is the next-step view of the same data: same envelopes, post-retirement targets, anomaly flags tuned for the new cash flow. The calculation rendered below makes the cash-flow swing concrete — a $299/month increase in health-premium debits for the typical couple, $3,589.32 a year, and that's before any IRMAA, dental, vision, or coinsurance.

What I'd actually track in month 6 of retirement

A retirement-grade expense tracker doesn't need a long list of metrics. Five are usually enough: rolling-three-month healthcare spend (with SSA deductions reincorporated); year-to-date discretionary spend versus the plan; running 12-month taxable-income total (the input to the IRMAA two-year lookback that will hit Medicare premiums when the household reaches 73 and RMDs begin under SECURE 2.0)^[]; sinking-fund balances for the next property tax bill and the annual Medigap renewal; and a count of recurring subscriptions that have rolled over since retirement began.

A small, honest caveat: this framework is least useful for retirees who kept employer-sponsored retiree health coverage past 65 (a shrinking population, but real for some public-sector and union retirees). For that group, Part B is the main change, but the supplement-and-Part-D layering doesn't apply. The five-metric short list still works; the healthcare line is just simpler.

The point of an expense tracker for recent retirees isn't to win the optimization game. It's to make the year-1 reorganization visible while there's time to do anything about it — to see the pivot, not just the total.
