How To Create A Retirement Budget

How to Create a Retirement Budget: A Step-by-Step Guide

One of the most important steps in retirement planning is building a realistic budget. Without a clear picture of your expected income and expenses, it’s nearly impossible to know if you’re saving enough or if your nest egg will last. A retirement budget differs from a working-years budget in several key ways: your income sources change, some expenses decrease, and others (like healthcare) often increase significantly.

This guide walks you through the process of creating a retirement budget from scratch, with real numbers and worked examples to help you build your own.

Why a Retirement Budget Matters

According to the Employee Benefit Research Institute, nearly half of American households are at risk of not having enough money to cover basic expenses and healthcare costs in retirement. A well-constructed budget helps you answer critical questions:

How much do I need to save before I retire?
Can I afford to retire at my target age?
How long will my savings last?
Where can I cut costs if my savings fall short?

Building a retirement budget is not a one-time exercise. It’s a living document you revisit and adjust as your circumstances change. But getting started now, even if retirement is decades away, gives you an enormous advantage.

Step 1: Estimate Your Retirement Income Sources

The first step is to identify every source of income you expect to have in retirement. Most retirees rely on a combination of the following:

Social Security

As of 2024, the average monthly Social Security retirement benefit is approximately $1,976, according to the Social Security Administration. Your actual benefit depends on your earnings history, the age you claim, and other factors. You can get a personalized estimate by creating an account at ssa.gov.

Keep in mind: claiming at age 62 reduces your benefit permanently, while delaying until age 70 increases it. For example, if your full retirement age (FRA) benefit is $2,000 per month, claiming at 62 could reduce it to roughly $1,400, while waiting until 70 could increase it to approximately $2,480.

Retirement Account Withdrawals

This includes withdrawals from 401(k) plans, traditional IRAs, Roth IRAs, 403(b) plans, and similar accounts. The amount you can withdraw depends on your total savings, your investment returns, and how long you need the money to last.

For example, if you have $500,000 in retirement savings and plan a 30-year retirement, withdrawing 4% in the first year would give you $20,000 annually (about $1,667 per month). However, this approach has trade-offs. Withdrawing too much too early increases the risk of running out of money, while withdrawing too little may mean unnecessarily reducing your quality of life. There is ongoing debate among financial researchers about appropriate withdrawal percentages under different market conditions.

Pensions

If you’re among the decreasing number of workers with a defined benefit pension, contact your plan administrator for an estimate of your monthly benefit. According to the Bureau of Labor Statistics, only about 15% of private industry workers had access to a defined benefit pension plan as of 2023.

Other Income

This might include rental income, part-time work, annuity payments, or income from a business. Be conservative in your estimates for sources that aren’t contractually guaranteed.

Worked Example: Estimating Monthly Retirement Income

Let’s say Maria, age 64, is planning to retire at 65. Here are her projected income sources:

Social Security (claiming at 65): $1,850 per month
401(k) balance of $400,000, planning to withdraw 4% annually: $16,000 per year, or $1,333 per month
Small pension from a previous employer: $350 per month

Maria’s estimated gross monthly retirement income: $3,533

After accounting for taxes on her 401(k) withdrawals and a portion of her Social Security (which may be taxable depending on total income), her net monthly income might be closer to $3,100. Tax impacts vary widely based on state of residence, filing status, and total income, so consulting a tax professional is valuable here.

Step 2: Categorize Your Expected Expenses

Now comes the most detailed part of the process: listing every expense you expect to have in retirement. It helps to break these into categories.

Essential (Fixed) Expenses

These are costs you must pay regardless of your lifestyle choices:

Housing: Mortgage or rent, property taxes, homeowner’s insurance, maintenance, HOA fees. Housing is typically the largest retirement expense. The Bureau of Labor Statistics reports that households headed by someone 65 or older spend an average of about 35% of their budget on housing.
Healthcare: Medicare premiums (Part B standard premium is $185 per month in 2025), supplemental insurance (Medigap or Medicare Advantage), prescription drug coverage (Part D), dental and vision care, and out-of-pocket costs. Fidelity estimated that an average 65-year-old couple retiring in 2024 may need approximately $315,000 for healthcare expenses throughout retirement.
Food and groceries: The BLS Consumer Expenditure Survey shows households age 65 and older spend an average of roughly $600 to $700 per month on food.
Utilities: Electricity, gas, water, internet, phone.
Insurance: Auto, life (if still needed), umbrella policy.
Transportation: Car payment, gas, maintenance, registration, or public transit costs.
Taxes: Federal and state income taxes, property taxes.

Discretionary (Variable) Expenses

These are costs you have more control over:

Travel and leisure: Vacations, hobbies, entertainment, dining out.
Gifts and charitable giving: Birthday gifts, holiday spending, donations.
Personal care: Clothing, haircuts, gym memberships.
Subscriptions: Streaming services, magazines, club memberships.

Often-Overlooked Expenses

Many retirement budgets fail because they miss these categories:

Home repairs and replacements: A new roof, HVAC system, or appliance can cost thousands. Setting aside $200 to $400 per month for home maintenance is a common planning approach.
Long-term care: The Genworth Cost of Care Survey reports that the national median cost of a private room in a nursing home was over $9,700 per month in 2023. Not everyone will need long-term care, but the risk is significant. The Department of Health and Human Services estimates that about 56% of people turning 65 today will need some form of long-term care.
Inflation: Even modest inflation erodes purchasing power over time. At 3% annual inflation, something that costs $1,000 today will cost about $1,344 in 10 years and $1,806 in 20 years.
Helping family members: Many retirees provide financial support to adult children or aging parents.

Step 3: Build Your Budget Spreadsheet

Using Maria’s example, here is what a monthly retirement budget might look like:

Monthly Income

Social Security: $1,850
401(k) withdrawal: $1,333
Pension: $350
Total gross income: $3,533
Estimated taxes: -$433
Total net income: $3,100

Monthly Expenses

Housing (mortgage paid off, but property taxes, insurance, maintenance): $850
Healthcare (Medicare premiums, Medigap, prescriptions, dental): $550
Food and groceries: $500
Utilities: $250
Transportation: $300
Insurance (auto and umbrella): $150
Travel and entertainment: $200
Personal care and clothing: $100
Gifts and charitable giving: $100
Home repair reserve: $200
Miscellaneous and emergency buffer: $150
Total monthly expenses: $3,350

The Gap

In this example, Maria has a monthly shortfall of $250. Her expenses exceed her income by $3,000 per year. Over a 25-year retirement, that gap would total $75,000 in today’s dollars, and significantly more when adjusted for inflation. This is exactly the kind of insight a retirement budget reveals before you actually retire.

Step 4: Close the Gap

If your projected expenses exceed your projected income, you have several options to explore. Each has trade-offs:

Reduce Expenses

Downsize your home to lower housing costs. Trade-off: moving can be stressful and may take you away from your community.
Relocate to a lower cost-of-living area. Trade-off: distance from family and established healthcare providers.
Cut discretionary spending. Trade-off: reduced quality of life and enjoyment.

Increase Income

Delay retirement by a year or two to continue saving and allow investments more time to grow. Trade-off: fewer years of retirement, and health may decline.
Work part-time in retirement. Trade-off: less free time, and earnings may affect Social Security benefits if claimed before full retirement age.
Delay Social Security to increase your monthly benefit. Trade-off: you need other income to bridge the gap, and the breakeven point is typically around age 80, meaning those with shorter life expectancies may receive less total.

Adjust Your Savings Strategy Now

If retirement is still years away, increasing your contributions can make a dramatic difference. In 2025 and 2026, the 401(k) contribution limit is $23,500 per year, with an additional $7,500 catch-up contribution allowed for those age 50 and older. For 2025, workers ages 60 through 63 can make an enhanced catch-up contribution of up to $11,250.

Worked example: If you are 45 years old and currently have $150,000 saved, contributing $750 per month (about $9,000 per year) with an assumed average annual return of 7% before inflation, you would accumulate approximately $708,000 by age 65. Increasing that contribution to $1,200 per month ($14,400 per year) with the same assumptions would result in approximately $918,000. That additional $450 per month in contributions translates to roughly $210,000 more at retirement.

Note: a 7% average return is a commonly used assumption based on long-term historical stock market performance, but actual returns vary significantly year to year. Your results could be substantially higher or lower depending on market conditions, asset allocation, and fees.

Step 5: Plan for Different Phases of Retirement

Retirement is not one uniform period. Financial planners often describe three phases:

The Go-Go Years (ages 65 to 75)

This is typically the most active and expensive phase. Travel, hobbies, dining out, and entertainment spending tend to be highest. Your budget may look similar to your working years, minus commuting and work-related costs.

The Slow-Go Years (ages 75 to 85)

Activity levels tend to decrease. Travel and entertainment spending often drops, but healthcare costs begin to rise. Overall spending may decrease by 10% to 20% compared to the early years.

The No-Go Years (ages 85 and beyond)

Healthcare and potential long-term care costs can dominate the budget during this phase. Daily living expenses may decrease, but medical costs can surge. This is often the most financially unpredictable phase of retirement.

A well-designed retirement budget accounts for these shifting patterns rather than assuming flat spending throughout.

Step 6: Stress-Test Your Budget

A good retirement budget is tested against unfavorable scenarios. Consider how your budget holds up under these conditions:

Higher inflation: What if inflation averages 4% instead of 3%? Over 20 years, that difference compounds significantly.
Market downturn early in retirement: A major market decline in the first few years of retirement can severely impact how long your savings last, even if markets recover later. This is known as sequence-of-returns risk.
Unexpected healthcare costs: A major illness or the need for long-term care can add thousands of dollars per month to your expenses.
Living longer than expected: Planning for a 30-year retirement when you only expect 20 provides a crucial buffer.
Loss of a spouse: The surviving spouse may lose one Social Security benefit while some expenses remain largely the same.

Running your budget through these scenarios helps you identify vulnerabilities and make adjustments while you still have time.

Step 7: Review and Revise Annually

Your retirement budget is a living document. Review it at least once a year and update it when major life changes occur. Key triggers for revision include:

Changes in health status
Significant market gains or losses
Changes in tax law or Social Security rules
Paying off a mortgage or other debt
Relocating
Changes in family circumstances

Common Retirement Budget Mistakes to Avoid

Underestimating healthcare costs: Healthcare is often the fastest-growing expense in retirement. Budget generously and plan for increases.
Ignoring inflation: A budget that works today may fall short in 15 years if you don’t account for rising prices.
Forgetting about taxes: Withdrawals from traditional 401(k) and IRA accounts are taxed as ordinary income. Up to 85% of Social Security benefits may also be taxable depending on your combined income.
Being too optimistic about investment returns: Using historical averages is a starting point, but building in a margin of safety is prudent.
Not budgeting for fun: A retirement budget that eliminates all enjoyment is unlikely to be followed. Include reasonable amounts for travel, hobbies, and entertainment.
