As you create your retirement budget, it’s helpful to keep two issues in mind. First, clarify your needs: determine how much you must set aside to cover essential expenses and how much you would like to spend to maintain your preferred lifestyle. Second, assess your capacity by estimating how much income your portfolio can reasonably and sustainably generate.
Your retirement budget will lie at the intersection of these numbers, where your capacity meets your needs. In this case, let’s assume you have a two-person household, $4,500 per month in Social Security benefits and a $1.5 million IRA balance. Here are a few things to consider as you prepare for building this retirement budget.

Step 1: Consider Your Goals
Before anything else, figure out your personal and financial goals for retirement.
For example, between returns and security, think about what you’ll prioritize when it comes to your finances. Do you want to retire right now at 63, or will you wait until age 67? Will you maintain your current lifestyle and location, or will you look for a change or cheaper/pricier area? Do you plan on continuing to work, and when will you start taking Social Security? Do you have any specific goals for estate planning?
This may seem like a wall of questions, but all of these factors will determine how you manage your money throughout the course of retirement. Being very intentional with your choices can allow you to maximize your money as you move through retirement. (And if you need help building a retirement plan, talk to a financial advisor.)
Step 2: Make a Budget for Your Needs and Lifestyle
Once you have a sense of your goals, it’s time to think about your spending. A rule of thumb is that most households need about 80% of their pre-retirement budget to meet their in-retirement needs. Beyond that, some critical issues to consider include what’s below.
Housing
If you own your home, make sure to set aside money for taxes, insurance and maintenance. If you rent your home, budget for annual rent increases. These typically exceed core inflation, and sometimes by quite a lot depending on where you live. After all, rent is expensive, but so is a new roof.
Location and Personal Inflation
How expensive is your hometown? Retiring to Michigan’s Upper Peninsula will cost far less than living in San Francisco or Boston. You should also expect prices to increase more quickly in an expensive city, a concept known as “personal inflation rate.”
Lifestyle and Hobbies
Do you want to travel, attend concerts or spoil your grandkids? Do you enjoy gardening, cooking or working on cars? Whatever your personal hobbies are, account for them in your budget. A good way to calculate this is to start with your current spending on entertainment and hobbies and tweak from there.
Healthcare and Insurance
While most of your budget will decrease in retirement, your healthcare needs will almost assuredly grow. Price out both long-term care insurance plans and Medicare gap coverage plans, since you may want both forms of coverage. Beyond that, talk to your doctor so that you can begin reasonably planning for healthcare spending in the future.
General Spending
General spending includes just about all consumer goods, ranging from a new iPhone to picking up groceries. This “other” category makes up a significant portion of your monthly expenses, and you don’t want a budget that pays the rent, but leaves no room for these basics.
Step 3: Invest and Build an Income to Meet Your Budget

The final step is to decide how you will manage your income and your remaining assets over time. Here we have a two-person household with Social Security benefits and an IRA balance. Your Social Security income alone should cover much of your necessities. At $4,500 per month ($54,000 per year) between each of you, these benefits could cover many retired couples’ needs.
From there, let’s look at your IRA.
One of the first questions for a household preparing to retire is how to handle debt. At age 63, you can withdraw money from your IRA with no tax penalties, though you’ll still owe taxes. As a result, you may consider withdrawing a lump-sum amount to cover any remaining mortgage, auto, educational or other forms of significant debt. This will reduce your household’s fixed overhead and unproductive interest payments, but at the cost of cashing out some investments.
If you have significant debt, consider speaking with a financial advisor about your options.
Then there’s the question of long-term withdrawals. You have $1.5 million invested in a pre-tax traditional IRA. Using a 4.7% withdrawal strategy, based on updated research from the creator of the 4% rule, this account could potentially generate about $70,500 per year in inflation-adjusted income, depending on market conditions and portfolio allocation. Together with your Social Security, that would provide approximately $124,500 in your first year of retirement, or about $10,375 per month.
These numbers can change depending on your investment strategy decisions, though.
For instance, you could purchase a lifetime annuity with your $1.5 million IRA, which might generate similar or higher guaranteed payments depending on the options you look at. However, this type of annuity income is fixed, so you will need a plan to keep your spending power from eroding with time.
You could invest for more aggressive growth, too. This might involve building a mixed portfolio, seeking average annualized returns of about 8%, or invest in an S&P 500 index fund, seeking average annualized returns of about 10% based on historical averages. Both of these approaches can boost your potential withdrawals, but both come with periodic losses and down years.
Finally, don’t forget to anticipate taxes. You will owe income taxes on your IRA withdrawals. You will also almost certainly owe taxes on a percentage of your Social Security benefits being that your income will likely surpass the income thresholds set by the IRS for this. Again, be sure to include this in your budgeting.
Pulling it All Together
For a 63-year-old couple with $1.5 million in a traditional IRA and $4,500 per month in Social Security, a realistic retirement budget may fall in the range of approximately $100,000 to $125,000 per year before taxes, depending on how withdrawals are structured and how the portfolio is invested.
Using a 4.7% withdrawal framework suggests roughly $70,500 annually from the IRA, which combined with $54,000 in Social Security provides about $124,500 in gross income. After accounting for taxes, that likely translates into a net spending range closer to $95,000 to $110,000 annually. In many areas of the country, that can support a comfortable lifestyle, provided housing costs, healthcare expenses and debt are well managed.
Frequently Asked Questions (FAQ)
How much should I keep in cash during retirement?
Many retirees hold one to three years’ worth of expenses in cash or short-term investments. This can help cover spending needs during market volatility without forcing the sale of long-term investments at depressed prices.
How are Social Security benefits taxed in retirement?
Federal taxation of Social Security depends on your overall earnings in retirement. As much as 85% of your benefits can be included in taxable income, based on a formula that considers your adjusted gross income, tax-exempt interest and 50% of the benefits you receive.
How should my investment strategy change in retirement?
Many retirees shift toward a more balanced portfolio that prioritizes income generation and risk management. However, maintaining some exposure to growth assets like stocks can help offset inflation and support long-term sustainability. The right mix depends on your spending needs, time horizon and comfort with market volatility.
