Retirement Spending Calculator

Determine how much you can safely spend each year in retirement. This calculator finds a sustainable withdrawal amount from your portfolio based on your total savings, investment returns, and retirement timeline. It then combines this with your guaranteed income sources like Social Security and pensions to give you a total annual spending budget.

This tool is for anyone approaching or already in retirement who wants to answer the critical question: "How much can I afford to spend?" It helps you understand the relationship between your nest egg and your lifestyle. For a more comprehensive pre-retirement projection, use the main retirement calculator. To explore a specific withdrawal strategy, see the 4% rule retirement withdrawal calculator.

The calculator provides a "Spending Sustainability Score," showing how robust your plan is. You will see a breakdown of your annual spending, your initial withdrawal rate, and how long your money is projected to last. Charts visualize your income sources and how your portfolio balance changes over time, giving you a clear picture of your financial standing in retirement.

Begin by entering your portfolio details. In the "Total Retirement Savings" field, input the combined balance of all your investment accounts intended for retirement, such as your 401(k), IRA, and brokerage accounts. Next, enter your "Expected Annual Return," which is the average return you anticipate your investments will generate during retirement.

Then, detail your guaranteed income sources. Enter the total annual amount you expect from Social Security, any pensions, and other recurring income streams like annuities or rental properties. These sources form your income floor and reduce the amount you need to withdraw from your portfolio. If you're unsure about your Social Security benefit, our Social-Security-calculator can provide an estimate.

Next, set your retirement timeline. Input your "Current Age" (or the age you plan to retire) and your "Life Expectancy." A longer retirement horizon requires a more conservative spending plan.

Finally, you can adjust advanced assumptions by clicking the toggle. Set the "Inflation Rate" to model how the cost of living may rise over time. The "Spending Flexibility" input lets you specify how much you'd be willing to cut spending during a market downturn, which can significantly improve your plan's chances of success.

Total Retirement Savings

This is the starting value of your investment portfolio at the beginning of retirement. Include all assets you plan to draw from, such as a 401(k), Traditional IRA, Roth IRA, and taxable brokerage accounts. A larger starting portfolio can support a higher level of spending. For an idea of how long a specific amount might last, see our guides on how long $1 million will last in retirement and how long $500k will last.

Expected Annual Return

This is the average annual growth rate you expect from your investments during retirement. This figure should be a long-term average, as market returns will vary year to year. Retirees often adopt a more conservative asset allocation, so a return of 5-6% is a common assumption for a balanced portfolio. Overly optimistic projections can lead to unsustainable spending recommendations.

Guaranteed Income Sources (Social Security, Pension, Other)

These are reliable, recurring income streams that are not dependent on market performance.

• Social Security: Enter your estimated annual benefit. You can find this on your statement from the Social Security Administration. The timing of when you claim can significantly impact this amount; learn more about when to take Social Security.
• Pension: If you have a defined-benefit pension, enter the annual payout here.
• Other Income: Include any other predictable income, such as payments from an annuity, rental property income, or royalties.

A strong base of guaranteed income reduces the pressure on your portfolio, allowing it to last longer or support a higher discretionary spending level.

Timeline (Current Age & Life Expectancy)

Your "Current Age" marks the start of the spending projection. "Life Expectancy" determines the length of the retirement period the calculator plans for. Since running out of money is a major risk, it is wise to be conservative and plan for a long life, perhaps to age 90, 95, or even 100.

Inflation Rate

Inflation erodes the purchasing power of your money over time. The calculator uses this rate to adjust your spending needs upwards each year, ensuring your lifestyle can keep pace with rising costs. A long-term historical average for inflation in the U.S. is around 3%. Learn more about how inflation affects retirement savings.

Spending Flexibility

This input quantifies your willingness to reduce discretionary spending during years when the market performs poorly. A higher flexibility percentage (e.g., 10-15%) indicates you are willing to tighten your belt, which acts as a safety valve for your portfolio and dramatically increases the sustainability of your plan.

This calculator determines a sustainable spending level by combining a formula-based approach with a year-by-year simulation.

First, it calculates a "real rate of return" by adjusting your expected annual return for the inflation rate. This real return represents the growth of your purchasing power.

Using this real return, your total savings, and your retirement timeline, the calculator employs an annuity formula to determine the maximum level amount you can withdraw each year (adjusted for inflation) without depleting your portfolio before your life expectancy. This is your "Safe Withdrawal Amount."

Your total annual spending is then calculated by adding this Safe Withdrawal Amount to your total guaranteed income (Social Security, pension, etc.).

Finally, to validate this spending level, the calculator runs a year-by-year projection. It starts with your total savings, subtracts the inflation-adjusted withdrawal for that year, and then grows the remaining balance by your expected annual return. This process repeats for each year of your retirement, showing you the projected portfolio balance over time and confirming how long your money will last at that spending rate.

The calculator uses several key formulas to derive its results. The core calculation for the sustainable portfolio withdrawal is based on the present value of an annuity formula, solved for the payment amount.

Real Rate of Return

First, the nominal return is adjusted for inflation to find the real rate of return.

real_return = ((1 + annual_return) / (1 + inflation_rate)) - 1

Safe Withdrawal Amount

This formula calculates the annual, inflation-adjusted withdrawal your portfolio can sustain over your retirement timeline. N is the number of years in retirement (life_expectancy - current_age).

safe_withdrawal_amount = total_savings * (real_return / (1 - (1 + real_return)^-N))

If the real return is zero, a simpler formula is used:

safe_withdrawal_amount = total_savings / N

Total Annual Spending

Your total initial spending budget is the sum of the sustainable withdrawal from your portfolio and your guaranteed income sources.

total_annual_spending = safe_withdrawal_amount + social_security_annual + pension_annual + other_income_annual

Year-By-Year Projection

The calculator simulates your retirement year by year to track your portfolio balance. For any given year:

inflation_adjustment = (1 + inflation_rate) ^ (current_year - start_year)

current_withdrawal = safe_withdrawal_amount * inflation_adjustment

ending_balance = (starting_balance - current_withdrawal) * (1 + annual_return)

A safe withdrawal rate is the percentage of your savings you can withdraw each year in retirement without a high risk of running out of money. The most well-known guideline is the 4% rule, which suggests withdrawing 4% of your initial portfolio balance in your first year of retirement and then adjusting that dollar amount for inflation in subsequent years.

Historically, this strategy has had a high success rate over a 30-year retirement period. However, the 4% rule is not a guarantee. Its success depends on future market returns and inflation, which can differ from the past. A lower withdrawal rate, such as 3% or 3.5%, is more conservative and provides a greater margin of safety, especially for those with a longer time horizon or lower risk tolerance. You can model this directly with our 4% rule withdrawal calculator.

This calculator determines a personalized withdrawal rate based on your specific inputs, including your investment return and retirement duration, which can result in a rate that is higher or lower than 4%. The "Portfolio Withdrawal" summary card shows you this calculated initial rate.

The 4% rule is a "fixed real spending" strategy because you withdraw the same inflation-adjusted amount each year, regardless of how your portfolio performs. This provides a stable income but can be risky. If the market drops early in your retirement, continuing to withdraw the same amount can rapidly deplete your principal—a risk known as sequence of returns risk.

A "dynamic spending" strategy, by contrast, adjusts withdrawals based on market performance. This is where the "Spending Flexibility" input on this calculator comes in. By indicating you're willing to reduce spending after a bad market year, you build a dynamic rule into your plan.

Other dynamic strategies include "guardrail" methods, where you increase spending if your portfolio grows above a certain threshold and decrease it if it falls below another. These approaches can significantly improve a plan's longevity by preventing you from overspending when your portfolio is down. A flexible plan is often a more resilient plan.

• Spending Sustainability Score: This score gives you a quick read on the health of your spending plan. A high score (80+) suggests your plan is robust and has a strong safety margin. A moderate score (50-79) indicates the plan is workable but may be vulnerable to poor market conditions. A low score (<50) is a warning that your spending may be too high for your resources.

• Total Annual Spending: This is the primary result—the total inflation-adjusted income your plan can support in the first year of retirement. It is broken down into "Portfolio Withdrawal" and "Guaranteed Income."

• Portfolio Longevity: This shows how many years your savings are projected to last at the calculated spending rate. Ideally, this number should meet or exceed your planned retirement duration (Life Expectancy - Current Age).

• Annual Spending Over Time Chart: This visualizes your income streams throughout retirement. The stacked bars show how much of your spending is covered by guaranteed income versus portfolio withdrawals. The orange line shows your total spending target as it increases with inflation.

• Spending Sources Breakdown: This donut chart provides a simple snapshot of where your first year's retirement income comes from, highlighting your reliance on portfolio withdrawals versus guaranteed sources.

• Spending at Different Confidence Levels: This table shows how your potential annual spending changes based on different probabilities of success. A 95% confidence level, for example, corresponds to a more conservative spending amount that has a very high historical probability of not running out of money.

If your sustainability score is lower than you'd like or your portfolio longevity is too short, there are several levers you can pull:

1. Reduce Target Spending: The most direct way to make a plan work is to spend less. Use the calculator to find a spending level that results in a higher score. A detailed retirement budget can help identify areas to trim.

2. Increase Guaranteed Income: Delaying Social Security is a powerful way to increase your guaranteed, inflation-protected lifetime income. Use our Social Security break-even calculator to explore different claiming ages.

3. Work Longer or Part-Time: Working even a few years longer allows your portfolio to grow, shortens the retirement period you need to fund, and can increase your Social Security benefit. Part-time work in retirement can also provide income to cover expenses without touching your portfolio.

4. Increase Spending Flexibility: If you have significant discretionary expenses (like travel or hobbies), a higher spending flexibility score can make your plan much more resilient. Committing to spending less when the market is down protects your principal.

5. Review Your Investment Strategy: Ensure your expected return is realistic for your asset allocation. While taking on more risk could lead to higher returns, it also increases volatility. A balanced approach is often best in retirement.

1. Underestimating Longevity: Planning to live only to the average life expectancy can be risky. It's safer to plan for a longer-than-average lifespan to ensure you don't outlive your money.

2. Ignoring Inflation: A 3% inflation rate can double the cost of living in 24 years. Failing to account for this will lead you to drastically underestimate your future spending needs.

3. Forgetting About Taxes: This calculator determines your pre-tax spending ability. Withdrawals from traditional 401(k)s and IRAs are generally taxable as ordinary income. You must account for taxes when creating your actual budget. Learn about tax-efficient withdrawal strategies.

4. Overlooking Healthcare Costs: Healthcare is one of the biggest expenses in retirement and often rises faster than general inflation. Use the retirement healthcare cost calculator for a more detailed estimate.
