How to Create a Retirement Budget: Top Picks for 2026
Last reviewed: June 2026
How to Create a Retirement Budget That Keeps Your Money Safe and Your Lifestyle Intact
You are 58 and your 401(k) balance sits at $250,000. You plan to stop working at 65. You worry that your savings won’t stretch through a 30-year retirement.
If you overestimate income or forget hidden costs, you could run out of cash. That means cutting back on health care, housing, or even basic groceries.
This post shows you step by step how to build a retirement budget. It covers income sources, expense categories, inflation adjustments, and a simple spreadsheet you can copy today.
This article provides educational information only and does not constitute financial or legal advice.
Key Takeaways
- List every retirement income source and note the date you expect each to start
- Categorize expenses into fixed, variable, and occasional groups.
- Use a 3 percent inflation assumption for the first ten years, then 2.5 percent thereafter.
- Build a “buffer” column equal to 10 percent of total projected expenses.
- Run the budget through a spreadsheet that flags any year where expenses exceed income.
- Review and adjust the budget annually or after any major life change.
Identify All Retirement Income
For a vetted, regularly updated list of tools that can help, explore our AI finance tools directory.
Start by writing down every paycheck, pension, or other cash flow you expect after you stop working. Include the month you think each will begin.
| Income Source | Monthly Amount | Start Date | Notes |
|---|---|---|---|
| Social Security | $2,200 | 01/2027 | Estimate based on SSA portal |
| Employer Pension | $1,000 | 01/2027 | Fixed for life |
| 401(k) Withdrawals | $1,500 | 01/2027 | 4 % rule withdrawal |
| Rental Property | $800 | 01/2027 | Net after mortgage |
| Part-time Consulting | $600 | 07/2027 | Expect 10 hours per month |
| Investment Dividends | $200 | 01/2027 | Varies with market |
Add the totals. In this example the first year of retirement brings $6,300 per month, or $75,600 annually.
Separate Fixed, Variable, and Occasional Expenses
Next, list every cost you expect to pay. Put each item in one of three buckets.
Fixed expenses stay the same each month. Examples: mortgage, insurance, utilities, and property taxes.
Variable expenses change with usage. Examples: groceries, fuel, medical copays, and entertainment.
Occasional expenses happen once or twice a year. Examples: car registration, home repairs, holidays, and long-term care premiums.
| Category | Monthly Avg. | Annual Total | Type |
|---|---|---|---|
| Mortgage | $1,200 | $14,400 | Fixed |
| Homeowners Insurance | $120 | $1,440 | Fixed |
| Electricity | $110 | $1,320 | Fixed |
| Water & Sewer | $45 | $540 | Fixed |
| Groceries | $500 | $6,000 | Variable |
| Fuel | $150 | $1,800 | Variable |
| Medical Copays | $200 | $2,400 | Variable |
| Entertainment | $150 | $1,800 | Variable |
| Travel | $300 | $3,600 | Variable |
| Car Registration | $80 | $80 | Occasional |
| Home Repairs | $250 | $3,000 | Occasional |
| Holiday Gifts | $200 | $200 | Occasional |
| Long-Term Care Premium | $400 | $4,800 | Fixed |
| Total | $3,515 | $42,180 | . |
In this scenario expenses total $42,180 per year, well below the $75,600 income forecast. That leaves $33,420 for savings, unexpected costs, or extra leisure.
Adjust for Inflation and Health Care Growth
Inflation erodes purchasing power. Most planners use a 3 percent rate for the first decade, then a slower 2.5 percent rate as you age. Health care typically rises faster, about 5 percent per year.
Create a column in your spreadsheet that multiplies each expense by the appropriate inflation factor for each future year. For health-related items, use the higher rate.
Example for Year 2:
- Fixed items: $14,400 × 1.03 = $14,832, Variable items: $12,660 × 1.03 = $13,040, Health care items: $2,400 × 1.05 = $2,520
Repeat for every year you plan to model, usually 30 years.
Build a Safety Buffer
Even a well-planned budget can be knocked off course by a market dip or a major repair. Add a buffer equal to 10 percent of each year’s projected expenses.
If Year 1 expenses are $42,180, the buffer is $4,218. Add this to the expense total before comparing it to income. The buffer creates a cushion that keeps you from dipping into principal early.
Run the Numbers in a Simple Spreadsheet
You do not need fancy software. A basic Google Sheet or Excel file works.
- Create tabs for Income, Expenses, Inflation, and Summary.
- In the Income tab, list each source, start date, and annual amount. Use a formula to sum only the years after the start date.
- In the Expenses tab, list each item, type, and Year 1 amount.
- In the Inflation tab, apply the 3 % or 5 % growth rates to each line for every future year.
- In the Summary tab, pull the total income, total expenses, and buffer for each year. Add a column that flags “Red” if expenses + buffer exceed income.
If any year turns red, adjust either income (delay withdrawals, add part-time work) or expenses (reduce travel, downsize housing). The spreadsheet will instantly show the impact of each change.
Test Different Withdrawal Strategies
The 4 % rule suggests pulling 4 percent of your portfolio each year, adjusted for inflation. Some retirees prefer a “dynamic” approach that reduces withdrawals after a market loss.
Create a scenario where you withdraw only 3.5 percent in years when the portfolio falls more than 10 percent. Compare the resulting cash flow to your budget. The spreadsheet can handle this by adding a conditional formula that reads the portfolio balance from a separate “Investments” tab.
Plan for Taxes
Even in retirement, you may owe federal or state tax on Social Security, pension, and investment withdrawals. Use the IRS tax tables for the year you retire to estimate the tax bite.
Assume a 12 percent marginal rate on $75,600 income. That yields $9,072 in tax. Subtract this from the income column before comparing to expenses. If you live in a state with income tax, add that amount as well.
Protect Your Savings with Insurance
Insurance protects against large, unexpected costs. Review these policies:
- Medicare Part B: $170 per month in 2026.
- Medicare Part D: $35 per month average.
- Supplemental (Medigap) Plan: $150 per month for a typical Plan F.
- Long-Term Care Insurance: $400 per month in this example.
Add these premiums to your fixed expenses. If you cannot afford them, consider a hybrid annuity that includes a care rider.
Create an Emergency Fund Separate from Retirement Assets
Set aside 6 to 12 months of living expenses in a liquid account. In this example, 12 months equals $42,180 ÷ 12 = $3,515. Keep this money in a high-yield savings account that earns at least 2 percent APY.
Having cash on hand prevents you from selling investments at a loss during a market downturn.
Review and Update Annually
Your budget is a living document. Each year, plug in actual numbers for income, expenses, and inflation. Adjust the buffer if you notice a pattern of overspending or if health costs rise faster than expected.
A yearly review also lets you incorporate life events: a grandchild’s college tuition, a move to a lower-cost state, or a change in marital status.
Fifth H2 Heading (Optional Title) to Sample Budget Spreadsheet Template
Below is a link to a free Google Sheet template that follows the structure described above. You can copy it to your own Drive and start filling in numbers right away.
Retirement Budget Template to Copy to Drive
The template includes:
- Income tab with start-date logic.
- Expense tab with type classification.
- Inflation calculator for each line item.
- Summary tab with red-flag alerts.
- Tax estimator for federal and state rates.
Use the sheet to test “what-if” scenarios such as:
- Delaying Social Security by two years.
- Reducing travel budget by 30 percent.
- Adding a $5,000 home repair in Year 5.
Seeing the numbers change in real time helps you stay in control.
Sixth H2 Heading to Common Mistakes and How to Avoid Them
Many retirees stumble over a few predictable errors. Recognizing them early saves money and stress.
Mistake 1: Ignoring Inflation on Health Care Health costs rise faster than general inflation. Use a 5 percent growth rate for medical items, not the standard 3 percent.
Mistake 2: Over-estimating Investment Returns Assuming a 7 percent portfolio return is optimistic for a 60-plus age group. Base your budget on a 4-5 percent realistic return.
Mistake 3: Forgetting Required Minimum Distributions (RMDs) At age 73, the IRS forces withdrawals from traditional IRAs and 401(k)s. Include the RMD amount in your income column to avoid penalties.
Mistake 4: Not Accounting for Taxes on Social Security If your combined income exceeds $34,000, a portion of Social Security becomes taxable. Use the IRS worksheet to estimate the tax.
Mistake 5: Leaving the Buffer Too Small A 5 percent buffer may not survive a severe market dip. Keep it at 10 percent or more.
Mistake 6: Assuming Housing Costs Stay Fixed If you own outright, property taxes and insurance still rise. Apply a 2-3 percent increase each year.
Correct each mistake in your spreadsheet and re-run the analysis.
Frequently Asked Questions
How do I know if my withdrawal rate is safe?
Start with the 4 percent rule as a baseline. Run a Monte Carlo simulation in your spreadsheet by varying market returns. If more than 90 percent of scenarios keep your portfolio above zero for 30 years, the rate is likely safe.
Should I downsize my home before retirement?
Downsizing can free up equity and lower monthly expenses. Calculate the net cash after selling, closing costs, and buying a smaller home. If the net gain exceeds the buffer you need, downsizing may improve your budget.
What if my Social Security benefit is lower than expected?
You can delay claiming until age 70 to earn 8 percent more per year. Use the spreadsheet to compare the higher benefit against the lost years of income.
How much should I keep in cash for emergencies?
Aim for 6 to 12 months of total expenses, not fixed costs. In the example budget, that means $3,500 to $7,000 in a liquid account.
Do I need long-term care insurance if I have savings?
If you have at least $500,000 in liquid assets, you might self-fund care. However, costs can exceed $150,000 per year in a nursing home. Run both scenarios in the budget to decide.
How often should I revisit my retirement budget?
At least once a year, or after any major change such as a health event, inheritance, or market swing. Updating the numbers keeps the plan realistic.
