Retirement Budget Calculator

Estimate your monthly and annual spending in retirement. This calculator helps you build a detailed budget by comparing your current expenses to your future needs, category by category. See how costs like healthcare, travel, and housing may change, and find out if your planned retirement income from sources like Social Security and pensions will cover your new lifestyle.

This tool is for anyone creating a detailed financial plan, from those just starting to think about how to create a retirement budget to those fine-tuning their numbers before they stop working. It's a perfect companion to our main retirement calculator, which projects your savings over time, and our retirement expense calculator, which helps you itemize costs.

The calculator generates an "Income Coverage Score" to show how well your income matches your expenses. You'll see a clear monthly surplus or deficit, charts comparing pre- and post-retirement spending, and a breakdown of your retirement income sources and expense categories.

Start by entering your current monthly spending in the "Pre-Retirement Monthly Expenses" section. Fill out each category, from housing and food to travel and healthcare, as accurately as possible. This creates the baseline for your retirement budget.

Next, move to the "Retirement Spending Adjustments" section. For each category, enter the percentage of your current spending you expect in retirement. For example, if you plan to spend 30% less on transportation, enter "70%". If you expect healthcare costs to double, enter "200%". The calculator will show you the new dollar amount next to the percentage.

Then, list all your expected "Monthly Income Sources in Retirement." Include guaranteed income like your estimated Social Security benefit, pension payments, and any annuity income. Also add potential income from part-time work, rental properties, or other sources.

Finally, you can open the "Advanced Settings" to adjust the long-term inflation rate, which helps you understand the future purchasing power of your budget. Once all your numbers are in, click "Calculate" to see your detailed retirement budget analysis.

Pre-Retirement Monthly Expenses

This section captures your current spending habits. Enter your average monthly costs for each of the 12 categories provided. This is the foundation of your projection, so be as realistic as you can. If you're unsure, track your spending for a month or two or review recent bank and credit card statements. For a more granular approach, use the retirement expense calculator.

Retirement Spending Adjustments

This is where you model how your life will change in retirement. Instead of guessing a new dollar amount, you estimate the change as a percentage.

• Housing: May decrease if your mortgage is paid off, but property taxes and maintenance remain.
• Transportation: Often decreases without a daily commute.
• Healthcare: Almost always increases. A 200% adjustment is a common starting point. See how much healthcare costs in retirement for more detail.
• Travel & Entertainment: Many retirees increase spending here, especially in the early years.
• Food: May decrease slightly without work lunches, but this can vary.

Think through your retirement goals to make these estimates. More travel means a higher percentage; downsizing your home means a lower one.

Monthly Income Sources in Retirement

This section totals all the money you expect to have coming in each month, not including withdrawals from your savings.

• Social Security: Enter your estimated monthly benefit. You can get a personalized estimate from the Social Security Administration's website or use our Social Security calculator to see how your claiming age affects the amount.
• Pension: If you have a defined benefit pension, enter the expected monthly payout.
• Annuity Income: If you own or plan to buy an annuity, enter the guaranteed monthly income.
• Part-Time Work, Rental Income, Other Income: Include any other reliable cash flow you anticipate. Having multiple income streams can make your plan more resilient.

Settings (Retirement Age & Inflation Rate)

The Retirement Age input helps frame the context of your budget but does not affect the core calculation in this specific tool, which focuses on a snapshot of your monthly budget. The Inflation Rate is a crucial assumption for long-term planning. It shows how the cost of living may erode your purchasing power over time. A budget that looks great today may feel tight in 20 years if you don't account for rising prices. Learn more about how inflation affects retirement savings.

This calculator performs a direct comparison of your income and expenses in retirement to determine if you have a surplus or a shortfall. It does not project portfolio growth or withdrawals over time.

First, it calculates your total pre-retirement monthly spending by summing the values you enter for each expense category.

Second, it calculates your projected retirement monthly spending. For each category, it takes your pre-retirement expense and multiplies it by the adjustment percentage you provide (e.g., $500 in transportation x 70% = $350). It then sums these new values to get your total retirement monthly expense.

Third, it calculates your total monthly retirement income by adding up all the income sources you enter, such as Social Security, pension, and part-time work.

Finally, it subtracts your total retirement expenses from your total retirement income to find your monthly surplus or deficit. The "Income Coverage Score" is calculated based on what percentage of your expenses are covered by your income.

The calculations are based on straightforward arithmetic to compare your income and expenses.

Category-Level Retirement Expense

For each spending category, the formula is:

retirement_expense = pre_retirement_expense * (adjustment_percentage / 100)

Total Monthly Expenses

The calculator sums the individual category expenses for both pre- and post-retirement periods.

total_pre_retirement_expenses = sum(all pre_retirement_expense_categories)

total_retirement_expenses = sum(all retirement_expense_categories)

Total Monthly Retirement Income

This is the sum of all income sources you provide.

total_retirement_income = social_security + pension + annuity + part_time_work + rental_income + other_income

Monthly Surplus or Deficit

This is the core result showing the difference between your income and expenses.

monthly_surplus_or_deficit = total_retirement_income - total_retirement_expenses

Income Coverage Score

The score shows how well your income covers your expenses, capped at 99 for visualization purposes.

coverage_ratio = (total_retirement_income / total_retirement_expenses) * 100

score = min(99, coverage_ratio)

One of the biggest mistakes in retirement planning is assuming your expenses will simply drop by a fixed amount, like 20%. The reality is more complex: some costs fall, while others rise significantly.

Common Decreases:

• Housing: If you pay off your mortgage before retirement, this is often your biggest savings.
• Transportation: With no daily commute, costs for gas, maintenance, and public transit typically fall.
• Taxes: Income taxes may be lower, and you no longer pay FICA (Social Security and Medicare) taxes on earned income.
• Saving: You are no longer actively saving for retirement, freeing up that portion of your income.

Common Increases:

• Healthcare: This is the most significant increase for most retirees. Even with Medicare, you'll have premiums for Part B and Part D, supplemental plan costs, and out-of-pocket expenses for dental, vision, and hearing. It's wise to budget for costs to be at least double your pre-retirement spending. Use the retirement healthcare cost calculator for a detailed estimate.
• Travel: With more free time, many new retirees spend more on travel in their first 5-10 years of retirement than they ever did while working.
• Hobbies & Entertainment: More leisure time can lead to higher spending on hobbies, dining out, and entertainment.
• Home Maintenance: As your home ages, and you spend more time in it, maintenance and repair costs can increase.

Understanding this dynamic is key to building a budget that won't leave you short. For a deeper look, read about the biggest expenses in retirement.

A detailed budget is the bedrock of a successful retirement plan. It transforms a vague savings goal into a concrete monthly number. Here’s how to build one.

1. Track Your Current Spending: You can't plan for the future without knowing where your money goes today. Use the calculator's pre-retirement section as a guide to track your expenses for 1-3 months.
2. Estimate Retirement Changes: Go through your current spending line by line and think critically about how each item will change. Will you eat out more or less? Will you cancel subscription services you used for work? Use the "Retirement Spending Adjustments" section of the calculator to model these changes.
3. Factor in Healthcare: Don't guess. Research Medicare premiums, Medigap or Medicare Advantage plan costs in your area, and average out-of-pocket costs. A 65-year-old couple retiring in 2026 might need over $350,000 to cover medical expenses in retirement. Read our guide on how much healthcare costs in retirement.
4. Plan for Fun: Be realistic about your desired lifestyle. If you want to travel extensively, build that into the budget from day one. Underfunding your "wants" can lead to stress or unsustainable withdrawals later.
5. Include "Ghost" Expenses: Budget for irregular but predictable costs like property taxes, insurance premiums paid annually, car replacements, and major home repairs. Divide their estimated annual cost by 12 and add it to your monthly budget.
6. Build a Buffer: Always include a miscellaneous or contingency category for unexpected costs. This prevents a single surprise expense from derailing your entire plan.

Your results provide a clear snapshot of your retirement financial health.

• Income Coverage Score: This gauge gives you an at-a-glance summary. A score near 100 means your recurring income covers your recurring expenses. A lower score indicates a gap that must be filled by savings.
• Monthly Surplus or Deficit: This is the most important number. A surplus means you have extra cash flow for discretionary spending, saving, or unexpected costs. A deficit is the amount you'll need to withdraw from your retirement accounts (like a 401(k) or IRA) each month just to cover your budget.
• Deficit Callout: If you have a deficit, the calculator estimates the total savings needed to cover that annual shortfall using a 4% withdrawal rate. This connects your budget directly to your savings goal.
• Spending Comparison Chart: The vertical bar chart is a powerful visual tool. It lets you instantly see which categories, like healthcare and travel, are driving your retirement spending up and which, like transportation, are providing savings.
• Income & Expense Donuts: These charts show the composition of your financial life. Is your income well-diversified, or are you relying heavily on one source? What are your three biggest expense categories in retirement?
• Category Detail Table: This table provides the raw numbers, showing the pre-retirement cost, retirement cost, and the dollar and percentage change for every single category. Use this to pinpoint exactly where your budget is changing.

If the calculator shows a significant deficit, don't panic. You have several levers you can pull to close the gap.

• Reduce Major Expenses: Housing is the largest expense for most people. Could you downsize, relocate to a lower-cost-of-living area, or get a roommate? Refinancing or paying off your mortgage before retirement can also free up significant cash flow. Explore the best states to retire for taxes.
• Increase Retirement Income: Can you delay Social Security to get a larger monthly benefit? Could you work part-time for the first few years of retirement? Explore creating other income streams through rental properties or annuities. The retirement income calculator can help you model different scenarios.
• Re-evaluate "Wants": Take a hard look at your discretionary spending adjustments, like travel and entertainment. You may need to scale back plans in the early years of retirement or find lower-cost ways to enjoy your hobbies.
• Plan for a Phased Retirement: Instead of stopping work cold turkey, consider transitioning to part-time work. This can bridge an income gap for several years while allowing your retirement savings to continue growing.

1. Underestimating Healthcare: Many people assume Medicare is free and covers everything. It isn't, and it doesn't. This is often the single biggest and most underestimated expense.
2. Ignoring Inflation: A budget that works at age 65 may be painfully tight by age 85. Even at 3% inflation, your cost of living will double in about 24 years.
3. Forgetting "One-Off" Expenses: People budget for groceries but forget they'll need to replace their car, their roof, or their furnace at some point. These large, infrequent costs must be planned for.
4. Being Overly Optimistic: It's tempting to assume you'll spend far less in retirement. While some costs drop, be realistic about new expenses related to hobbies, travel, and health.
5. Not Accounting for Taxes: Your Social Security benefits may be taxable, and withdrawals from Traditional IRAs and 401(k)s certainly are. Your budget needs to account for gross income, not just the net amount you need to spend. Learn about tax-efficient withdrawal strategies.
