IRA Annuity Calculator

Calculate the guaranteed lifetime income you could receive by converting a portion of your IRA into an annuity. This calculator directly compares the fixed annual payments from an annuity against a systematic withdrawal strategy, helping you answer the critical retirement question: "Should I annuitize my IRA?" Enter your IRA balance, age, and a few key assumptions to see a side-by-side projection of your income, portfolio balance, and overall lifetime payout.

This tool is for retirees and pre-retirees weighing the trade-offs between the security of guaranteed income and the flexibility of keeping funds invested. It helps visualize how an annuity can provide longevity insurance. For a broader view of your retirement finances, use the main retirement income calculator or the IRA withdrawal calculator to model different scenarios.

The results provide an "Annuity Benefit Score" to quickly gauge if annuitization is advantageous in your scenario. You'll also see charts comparing the annual income from each strategy, a projection of your remaining IRA balance under the withdrawal plan, and key insights into portfolio depletion risk and inflation protection.

This calculator models two distinct paths for your IRA funds: converting them to an annuity versus keeping them invested and taking regular withdrawals.

First, enter your core details in the "IRA & Annuity Details" section. Start with the IRA Balance to Annuitize, which is the amount of money you're considering using to purchase the annuity. Next, input your Current Age, as annuity payouts are highly dependent on age. Finally, enter the Annuity Payout Rate offered by an insurance company. This is the percentage of your principal they will pay you annually for life.

Next, define the comparison scenario under "Withdrawal Comparison." The Expected Return if Kept Invested is the average annual growth you anticipate if you don't annuitize and instead leave the funds in the market. The Withdrawal Rate if Kept Invested is the percentage you plan to withdraw each year, similar to the 4% rule.

For a more detailed analysis, use the advanced settings. Here you can specify the Annuity Type (fixed vs. variable), add a COLA Adjustment to model inflation protection, and include a Joint & Survivor benefit to see how providing income for a spouse affects your payout. Use the immediate annuity calculator for a more focused look at that specific product.

IRA Balance to Annuitize

This is the lump sum from your IRA that you plan to use to purchase an immediate annuity. It's often not your entire IRA balance. Many financial planners suggest annuitizing only a portion of your retirement savings to cover essential expenses, leaving the rest invested for growth and flexibility.

Current Age

Your age is one of the most significant factors in determining your annuity payout. Older individuals receive a higher payout rate because their life expectancy is shorter. Enter the age at which you plan to purchase the annuity.

Annuity Payout Rate

The payout rate is the percentage of your principal the insurance company agrees to pay you each year for the rest of your life. For example, a 6% payout rate on a $100,000 premium provides $6,000 per year. This rate is determined by the insurer based on your age, gender, and current interest rates. You typically get this rate by requesting a quote from an insurance company.

Expected Return if Kept Invested

This is your estimated average annual return if you choose not to annuitize and instead keep your IRA funds invested in a portfolio of stocks, bonds, and other assets. This is a critical assumption, as a higher return can make the systematic withdrawal strategy look more appealing, though it also comes with market risk.

Withdrawal Rate if Kept Invested

This is the percentage of your initial IRA balance you plan to withdraw each year. A common starting point is 4%, based on the well-known 4% rule. A higher withdrawal rate provides more income but significantly increases the risk of running out of money. You can test different rates with the nest egg withdrawal calculator.

Annuity Type

This advanced setting lets you choose between a fixed annuity (1) and a variable annuity (0). A fixed annuity offers guaranteed, predictable payments that never change. A variable annuity links payments to the performance of underlying investments, meaning income can rise or fall with the market. This calculator simplifies the variable option by assuming it matches your expected return.

COLA Adjustment

A Cost-Of-Living Adjustment (COLA) increases your annuity payments each year to help offset the effects of inflation. Adding a COLA rider will reduce your initial payout but helps your income maintain its purchasing power over a long retirement. Learn more about how inflation affects retirement savings.

Joint & Survivor

This option (1 for Yes, 0 for No) structures the annuity to continue paying out to a surviving spouse after your death. Selecting this benefit provides crucial income for a partner but will lower the initial payout amount, typically by 15-25%, compared to a single-life policy.

This calculator runs a parallel projection to compare two scenarios until age 95.

Scenario 1: The IRA Annuity The annuity calculation is straightforward. It takes your IRA Balance to Annuitize and multiplies it by the Annuity Payout Rate to determine your fixed annual income. If a Joint & Survivor option is selected, it applies a reduction factor to the payout. If a COLA Adjustment is included, the annual income increases by that percentage each year. This income is guaranteed for life, regardless of market performance or how long you live.

Scenario 2: Systematic Withdrawals The withdrawal scenario starts with the same IRA Balance. In the first year, it calculates your income by multiplying the balance by your chosen Withdrawal Rate. The remaining balance is then assumed to grow by your Expected Return. In each subsequent year, the process repeats: the withdrawal amount (which may be adjusted by the COLA) is taken, and the new, lower balance grows by the expected return. This continues year-by-year, showing how the portfolio balance depletes over time. The projection stops if the balance hits zero.

The calculator does not account for taxes on IRA withdrawals, specific annuity product fees, or the sequence of returns risk (the negative impact of poor market returns early in retirement). All withdrawals from a Traditional IRA are generally taxed as ordinary income. For more on taxes, see how to withdraw from retirement accounts tax-efficiently.

The calculator uses distinct formulas for the annuity and withdrawal scenarios, then compares them.

Annual Annuity Income

This formula calculates the guaranteed income from the annuity.

survivor factor = if joint survivor is "Yes", then 0.8, else 1.0

annual annuity income = ira balance x (payout rate / 100) x survivor factor

For projections over time with a COLA:

income in year N = initial annual annuity income x (1 + COLA rate) ^ (N - 1)

Annual Withdrawal Income & Projection

This shows the income and remaining balance for the systematic withdrawal plan.

initial annual withdrawal = ira balance x (withdrawal rate / 100)

The year-by-year projection works as follows:

withdrawal for current year = initial annual withdrawal x (1 + COLA rate) ^ (years since retirement)
withdrawal for current year = min(withdrawal for current year, starting balance for year)

investment growth = (starting balance for year - withdrawal for current year) x (expected return / 100)

ending balance for year = starting balance for year - withdrawal for current year + investment growth

This loop repeats each year until age 95 or until the balance reaches zero.

Annuity Benefit Score

The score provides a quick summary of the annuity's advantages based on your inputs.

income ratio = annual annuity income / initial annual withdrawal
longevity bonus = if withdrawal balance runs out before age 95, then 20, else 0

score = min(99, max(1, (income ratio * 50) + longevity bonus))

A higher score indicates the annuity provides a significant income advantage and/or protects against a high risk of depleting your assets.

An IRA annuity is not a special type of IRA. It's a strategy where you use funds from your existing Traditional, Roth, or SEP IRA to purchase an annuity contract from an insurance company. The most common type used for this purpose is a Single Premium Immediate Annuity (SPIA).

With a SPIA, you give the insurance company a lump-sum premium (your "IRA Balance to Annuitize"). In exchange, the insurer promises to pay you a fixed, regular income for a specified period, most often for the rest of your life. This transaction effectively converts a portion of your market-exposed retirement assets into a personal pension, providing a predictable income stream to cover your living expenses.

The money moved into the annuity retains its tax-deferred status. For a Traditional IRA, the income payments you receive are fully taxable as ordinary income. For a Roth IRA, the payments are tax-free, assuming you meet the standard requirements for qualified distributions. This process can also help satisfy Required Minimum Distributions (RMDs), as annuity payments generally count toward your annual RMD amount.

Deciding whether to annuitize part of your IRA involves a significant trade-off between security and flexibility.

Pros of Annuitizing an IRA:

• Guaranteed Lifetime Income: The primary benefit is creating a reliable income stream you cannot outlive. This "longevity insurance" protects against the financial risk of a longer-than-expected lifespan.
• Simplicity and Predictability: Annuity payments are automatic and predictable, simplifying your retirement budgeting. You don't have to manage withdrawals or worry about market fluctuations affecting your essential income.
• Reduced Market Risk: By converting assets to an annuity, you shield that portion of your savings from stock market downturns. This can provide peace of mind, especially for risk-averse retirees.
• Behavioral Guardrails: An annuity can prevent the temptation to overspend or make poor withdrawal decisions during market volatility.

Cons of Annuitizing an IRA:

• Loss of Liquidity: The biggest drawback is irrevocability. Once you purchase an immediate annuity, you cannot access your principal. The money is locked in, which can be problematic if you face a large, unexpected expense.
• Inflation Risk: Basic fixed annuities provide a level payment for life. Over decades, inflation will erode the purchasing power of that income. Inflation-adjusted riders (COLAs) are available but reduce your starting payout.
• Lower Returns: You are trading potential market growth for security. In a strong bull market, an invested portfolio will likely outperform the fixed return implicit in an annuity.
• Less for Heirs: In a basic life-only annuity, payments stop upon your death, and the insurance company keeps the remaining principal. Options like "period certain" or "cash refund" can provide a death benefit but also reduce your lifetime payouts. A standard investment portfolio can be passed directly to beneficiaries.

The calculator's outputs are designed to help you weigh the pros and cons based on your specific numbers.

• Annuity Benefit Score: This is a high-level summary. A score above 80 suggests the annuity offers a clear advantage in income and longevity protection. A score below 50 indicates that, based on your assumptions, a systematic withdrawal strategy may provide higher income, though with more risk.
• Monthly/Annual Annuity Income: This is your guaranteed paycheck from the annuity. It's the secure foundation of your retirement income.
• Systematic Withdrawal: This is the initial annual income from your invested portfolio. It's often higher at the start but is not guaranteed and depends on market performance.
• Income Difference: This card shows which strategy provides more income in the first year. A positive number means the annuity pays more; a negative number means withdrawals start higher.
• Income Comparison Chart: This visualizes the two income streams over time. You'll see the fixed (or slowly rising COLA) line of the annuity versus the potentially declining line of the withdrawal strategy if the portfolio depletes.
• Balance Depleted (on Score Gauge): This is a critical output. It shows the age at which your IRA balance is projected to run out under the withdrawal plan. If it's before your life expectancy (e.g., age 95), it highlights a significant longevity risk that the annuity would solve.

"Improving" your results means finding the right balance of security and flexibility for your needs. Use the calculator to test different approaches.

• Consider Partial Annuitization: You don't have to annuitize your entire IRA. Try running the calculator with 25% or 50% of your balance. This "bucket strategy" approach uses the annuity to cover essential needs while leaving other funds invested for growth and emergencies.
• Shop for Higher Payout Rates: Payout rates can vary significantly between insurance companies. Get quotes from several top-rated insurers to ensure you're getting the most competitive rate. A half-percent difference can mean thousands of dollars over a lifetime.
• Test a COLA Adjustment: If you're worried about inflation, enter a 2% or 3% COLA. Notice how it lowers your starting income but results in a much higher income by your 80s or 90s.
• Adjust Your Withdrawal Rate: If the calculator shows your portfolio running out too early, try a lower withdrawal rate (e.g., 3.5% instead of 4.0%). This demonstrates the trade-off between current income and long-term sustainability. The 4% rule calculator can help model this.

1. Annuitizing Too Much: Converting all your liquid assets into an annuity can be risky. Always maintain access to other funds for emergencies, healthcare costs, and discretionary spending.
2. Ignoring Inflation: Choosing a fixed annuity without considering how inflation will erode its value over 20-30 years is a major pitfall. A pension that seems adequate at 65 may feel small at 85.
3. Forgetting Your Spouse: If you are married, failing to select a joint and survivor option means your income stream will disappear when you die, potentially leaving your spouse in a difficult financial situation.
4. Chasing the Highest Payout Without Checking Insurer Ratings: An annuity is only as safe as the insurance company that backs it. Stick with highly-rated companies (e.g., A+ or better from A.M. Best).
5. Misunderstanding Fees and Riders: While this calculator models a simple immediate annuity, many annuity products are complex and come with high fees. Understand exactly what you are buying before you commit.
