Build a retirement budget for two by starting with your household’s actual spending, then replacing work-era income with estimates for each partner and testing whether the plan still works under changing costs, benefit timing, and a one-partner scenario. There is no reliable universal monthly figure for a couple: the right budget depends on your expenses, location, healthcare, debts, taxes, and plans.
Start with the household’s actual numbers
Set aside a year of statements and bills if you can. Looking across a full year helps reveal expenses that do not arrive every month, including property taxes, insurance premiums, car costs, repairs, and travel. If that feels like too much to tackle at once, begin by recording one week of spending and continue from there. The CFPB recommends listing income, tracking expenses, accounting for bill timing, and assembling a working budget based on your own household pattern: CFPB budgeting guidance.
Put both partners’ finances on the same household worksheet, but preserve which income, benefit, or coverage belongs to whom. That distinction matters when one person retires before the other, claims Social Security at a different age, or later needs to budget as a survivor.
Record every income source
List take-home pay, pensions, investment or rental income, and other recurring sources. For income that varies, Consumer.gov suggests adding the previous year’s total and dividing by 12 as a monthly planning estimate. Treat this as a way to build a current record—not as a forecast of retirement income. See Consumer.gov’s monthly budgeting process.

Capture monthly and irregular spending
Group the household’s expenses in a way that helps you make decisions. For example, separate housing and utilities from dining out and entertainment, then add categories that fit your lives. Convert irregular bills to monthly equivalents for planning: if a bill is paid once or twice a year, reserve a portion of its annual cost each month. This makes the monthly picture less likely to look affordable only because a large bill has not arrived yet.
Build a retirement version of the budget
Make a second estimate alongside the current household budget. The CFPB says comparing expected retirement income and expenses can help people understand how Social Security claiming choices affect their ability to meet needs and whether expenses or debt should be addressed before retirement. Its 2016 issue brief on Social Security claiming and retirement security also advises considering a spouse’s longer-term needs.

Estimate each partner’s income separately
For each person, record estimated Social Security benefits at plausible claiming ages, using that person’s own earnings record and assumptions. The Social Security Administration says retirement benefits may be claimed from age 62 through 70, and the monthly amount rises the longer a person waits, up to age 70. Use each partner’s personal estimates rather than a generic couple estimate; records and benefit amounts differ. The SSA’s Plan for Retirement page links to the agency’s planning resources.
Add pension income according to the applicable plan terms, plus other expected sources. Keep gross amounts distinct from spendable income: Social Security benefits may be taxable, and Medicare Part B premiums may be deducted from benefit payments. Tax treatment and premiums depend on current rules and individual circumstances, so do not treat a gross estimate as cash available for bills.
Review expenses instead of applying a percentage
Do not assume retirement spending will be a fixed percentage of current income or simply erase work-related categories. Go through each category and decide what changes, what continues, and what is newly added. A paid-off home can still require property taxes, homeowners insurance, utilities, and repairs. If you may move, compare the total cost of housing and local living costs—not just the mortgage payment. USAGov’s retirement planning tools include resources for comparing possible destinations.
Include healthcare transitions for both partners: when each person expects to leave employer coverage, what coverage may replace it, and what premiums and out-of-pocket costs belong in the plan. The IRS’s 2025 edition of Publication 554 lists Medicare Part B and Part D premiums among medical expenses under tax rules; that does not mean every such expense is deductible for every taxpayer.

Organize the plan into three spending groups
This three-part worksheet is a practical organizing choice, not an official government classification. Base it on observed spending and the life you intend to lead.
| Group | What to include | Budgeting question |
|---|---|---|
| Essential recurring | Housing, utilities, basic food, insurance, debt payments, and other bills the household must pay regularly | Which bills continue even if one person’s income changes? |
| Flexible lifestyle | Dining out, entertainment, hobbies, travel, and other expenses that can be adjusted | Which costs reflect your priorities, and which could be reduced if needed? |
| Irregular and contingency | Repairs, vehicle costs, annual premiums, property taxes, and other less frequent costs | How much should be set aside each month so a lumpy bill is not a surprise? |
Separating these groups helps reveal where you have flexibility without disguising expenses that are predictable but infrequent.

Show assumptions and test different futures
Write the budget in today’s dollars first and label the year those dollars represent. If you project costs into a future retirement date, state the inflation assumption rather than presenting future amounts as precise predictions. A CFPB toolkit published in 2015 uses 3% annual inflation to illustrate compounding: under that example, $1 becomes about $1.16 in five years and $1.34 in ten years. These are educational examples, not a current inflation forecast. The toolkit also cites a 60%–100% of current income range as general financial-planner advice, while emphasizing that the amount depends on what someone wants to do in retirement; treat it as a starting point, not a rule or personalized recommendation. See CFPB’s 2015 worker financial empowerment toolkit.
Rather than rely on one projection, make a lower-cost, central, and higher-cost version using assumptions you can explain. Change a few meaningful inputs—such as housing, healthcare, travel, or the date one partner stops working—and see which version remains workable. The goal is to expose sensitive points in the plan, not to assign unsupported odds to future outcomes.
Run a one-partner scenario
Rework the budget with one partner’s income removed or changed. Review survivor-benefit assumptions and costs that may remain despite the smaller household, such as housing, insurance, or property upkeep. Do not assume expenses will simply be cut in half, and do not assume one Social Security claiming choice is best for every couple. Eligibility, earnings records, ages, and household circumstances differ; consult official resources for the relevant benefit details.
Review the budget against what actually happens
At the end of each month, compare actual spending with the plan, note why amounts differed, and use that information to set the next month’s budget. Consumer.gov describes a cycle of planning monthly, recording spending, and using actual results to plan the next month; it sums up the approach this way: “A budget is something you use every month.” Read Consumer.gov’s “Making a Budget”, marked August 2024.
Refresh the retirement estimate when employment, health coverage, housing, debt, taxes, or household goals change. A budget is most useful as a working plan that reflects current facts, not a one-time calculation to file away.
