A great retirement budget does two things: it funds the life you want and shields you from the risks you can’t see yet. We’ll build yours step by step: then pressure-test it against health costs, inflation, taxes, market swings, and required distributions. Done right, your plan becomes a permission slip to enjoy your time without money anxiety.
Key takeaways (skim this first)
Start with income you can count on. Social Security typically replaces ~40% of pre-retirement earnings—most people need additional income sources or savings. Social Security
Use a conservative withdrawal starting point. Morningstar’s 2025 research pegs a baseline safe starting rate at ~3.7% for a 30-year plan (adjust if markets/lifestyle change). Morningstar
Budget healthcare separately. The 2025 Medicare Part B standard premium is $185/month (plus deductible/IRMAA for higher incomes). A typical 65-year-old may face ~$172,500 in lifetime health costs, excluding long-term care. CMS+1
Expect spending to shift. Healthcare rises with age; in 2023 households 65+ spent about $8,000/yr on healthcare on average. Plan for this trend line. FRED
Stress-test for longevity & long-term care. Roughly 70% of people turning 65 will need some form of long-term care; set aside a reserve or insurance strategy. ACL
Know your milestones. Required minimum distributions (RMDs) generally begin at age 73; Roth IRAs have no RMDs for original owners. Delaying Social Security up to age 70 increases benefits ~8% per year after full retirement age. IRS+1
Step-by-step: build a retirement budget you’ll actually use
1) Define your lifestyle (and season it changes)
Think in phases: “go-go” (travel/active), “slow-go,” and “no-go.” List your must-haves (housing, utilities, food, insurance) and your want-to-haves (travel, hobbies, gifting). Ground this in reality by pulling the last 12 months of spending, then adjust for any mortgage payoff, downsizing, or new hobbies. Older-household data show healthcare’s share tends to rise over time—plan for that drift. FRED
2) Map reliable income first (your “floor”)
List Social Security, any pensions/annuities, and guaranteed rental income. Remember: Social Security is designed to be a base—about 40% for the average worker—so most retirees need savings or part-time income to close the gap. Consider delaying benefits to increase the check—credits accrue monthly up to age 70 (about 8% per year from full retirement age). Social Security+1
3) Estimate healthcare and insurance precisely
Medicare Part B (2025): $185/mo standard premium; $257 annual Part B deductible; income-related surcharges (IRMAA) may apply. Add Medigap/Advantage and Part D costs. CMS
Lifetime out-of-pocket (typical 65-year-old, Original Medicare A/B/D, no LTC): around $172,500 (single). Budget it annually and keep a health-care sinking fund for spikes. Fidelity Newsroom
Reality check: Households 65+ spent ~$8,000 on healthcare in 2023; use your actual premiums and prescriptions to personalize. FRED
4) Calculate your “gap” and the portfolio needed to cover it
Annual spending (all-in) – guaranteed income = portfolio withdrawal need.
Start conservatively with ~3.7% as a baseline first-year withdrawal, then adjust for markets, taxes, and life events.
Example: If your spending is $70,000 and guaranteed income (SS + pension) is $38,000, your gap is $32,000. At 3.7%, target portfolio ≈ $865,000 ($32,000 ÷ 0.037). Morningstar
Pro tip: cover essentials (housing, utilities, food, insurance, meds) with guaranteed income (SS + pension + annuity/TIPS ladder). Let your portfolio fund discretionary items (travel, upgrades). This “floor-and-upside” approach reduces sequence-of-returns risk.
5) Plan for taxes, RMDs & timing
RMDs generally begin at 73; the first RMD can be delayed to April 1 of the following year (mind the double-distribution trap). Roth IRAs: no RMDs for original owners. IRS
Coordinate withdrawal order (taxable → tax-deferred → Roth) to manage tax brackets and IRMAA thresholds.
Harvest gains/losses opportunistically and keep one year of cash (plus 1–2 years in short-term Treasuries) for downturns.
6) Inflate smartly and revisit annually
Assume healthcare inflation can outpace general inflation. Re-price your prescriptions and premiums each year during open enrollment, and refresh travel and gift budgets as your interests evolve.

Pro tips to make it stick
Annual “open-enrollment” ritual: Re-shop Part D/Advantage, re-quote Medigap, and update doctors and meds. Part B is $185/mo in 2025; IRMAA cliffs make tax planning valuable. CMS
Healthcare reserve: Automate monthly transfers to a dedicated health fund; Fidelity’s 2025 estimate reminds us to plan big-picture costs. Fidelity Newsroom
Withdrawal flexibility beats rigidity: Start near 3.7%, then adjust based on returns and spending surprises (raise or cut 5–10% year-to-year). Morningstar
Sequence-risk shield: Keep 12–24 months of cash/short-term Treasuries so you aren’t forced to sell when markets dip.
Claiming strategy = free raise: If you can, delay Social Security; benefits grow about 8% per year after full retirement age until 70. Social Security
Mind the RMD clock: Plan tax-efficient Roth conversions before RMDs start at 73; Roth IRAs have no RMDs for original owners. IRS
Plan for care: With a ~70% chance of needing some long-term care, budget for premiums, a dedicated reserve, or a hybrid policy. ACL
FAQs
How much should I budget for healthcare if I’m 65 this year?
Start with your actual Medicare premiums (2025 Part B is $185/mo, plus Part D and any Medigap/MA premiums), then add your typical co-pays and prescriptions. A single 65-year-old retiring in 2025 may face ~$172,500 over retirement (Original Medicare A/B/D; no LTC), so build a yearly line item and a separate reserve. CMS+1
Is the “4% rule” still safe?
Treat it as history, not a promise. Morningstar’s 2025 analysis suggests ~3.7% as a conservative starting point for a 30-year plan; flexible strategies (guardrails, skip-inflation raises after bad years) can safely lift spending for many retirees. Morningstar
When do RMDs start—and do Roth IRAs have them?
Most tax-deferred accounts require RMDs at age 73; original-owner Roth IRAs do not. Plan ahead to avoid bracket creep and IRMAA surcharges. IRS
Should I delay Social Security?
If you have the savings/income to bridge the gap, delaying from full retirement age to 70 boosts benefits ~8%/yr, for higher lifelong, inflation-adjusted income and better survivor protection. Social Security
