Retirement Income Calculator

About the Retirement Income Calculator

The Retirement Income Calculator combines all your expected income sources — Social Security, pensions, annuities, part-time work, and portfolio withdrawals — to project your total monthly and annual retirement income. It then compares this to your estimated expenses to identify any surplus or gap.

Understanding your retirement income picture is essential for deciding when to retire, how to claim Social Security, and whether your savings will last. It gives a clear, consolidated view of your retirement cash flow.

Enter each income source and your expected monthly expenses to see the complete income breakdown. Many retirees discover that Social Security alone replaces only 30 to 40 percent of their pre-retirement income, leaving the remainder to be funded by pensions, savings withdrawals, and other sources. By combining all streams into a single view, you can identify whether your guaranteed income covers essential expenses and whether your portfolio only needs to fund discretionary spending — a distinction that dramatically affects how much investment risk you need to take.

When This Page Helps

Most retirees have income from multiple sources, making it hard to know the total without a consolidated view. This calculator brings everything together, shows what percentage each source contributes, and highlights whether you have a surplus or shortfall — the most important question in retirement planning. Seeing the full income picture in one place turns retirement from guesswork into a concrete, actionable plan.

How to Use the Inputs

1. Enter your expected monthly Social Security benefit.
2. Enter any pension income you expect (monthly).
3. Enter annuity income if applicable.
4. Enter expected part-time or side income.
5. Enter your retirement portfolio balance and planned withdrawal rate.
6. Enter your estimated monthly expenses in retirement.

Tips & Best Practices

• Delay Social Security to age 70 for 8% annual increases from your full retirement age benefit.
• Plan for healthcare costs — Medicare premiums, supplements, and out-of-pocket costs average $300-600/month per person.
• Include taxes in your expense estimate — Social Security and 401(k)/IRA withdrawals are taxable.
• Build in a buffer of 10-15% above planned expenses for unexpected costs.
• Consider part-time work in early retirement — even modest income dramatically extends portfolio longevity.
• Review your income plan annually and adjust withdrawal rates based on portfolio performance.

The Retirement Income Puzzle

Retirement income comes from multiple sources that start at different times and have different characteristics. Social Security begins at 62-70. Pensions start at a set date. Portfolio withdrawals are flexible. Assembling these pieces into a coherent monthly income plan is the central challenge of retirement planning.

Income Phases in Retirement

Many retirees experience distinct income phases. Early retirement (62-70) may include part-time work and delayed Social Security. The middle phase (70-80) typically has the most stable income. Late retirement (80+) often sees rising healthcare costs and declining income from part-time work. Plan your income strategy for each phase.

Protecting Against Longevity Risk

The biggest financial risk in retirement is living longer than your money lasts. Women especially should plan for a 30+ year retirement. Annuities, delayed Social Security claiming, and conservative withdrawal rates all help mitigate this risk.

Frequently Asked Questions

• How much income do I need in retirement?

  A common guideline is 70-80% of pre-retirement income, but your actual need depends on your lifestyle. If your mortgage is paid off, you may need less. If you plan to travel extensively, you may need more. Map out your actual expected expenses for the most accurate picture.

• Is Social Security enough to live on?

  Social Security often covers basic expenses but not a fully comfortable retirement on its own. It was designed to replace roughly 40% of pre-retirement income for average earners, so most retirees still need other income sources.

• What is a safe withdrawal rate for my portfolio?

  The classic 4% rule suggests withdrawing 4% of your portfolio in year one, then adjusting for inflation. Many planners recommend 3.25-3.5% for retirements lasting 30+ years. Higher withdrawal rates increase the risk of running out of money.

• Should I include part-time income?

  Yes, but be realistic about how long you'll want to or be able to work. Many retirees work part-time in early retirement (ages 62-70) but stop by their mid-70s. Plan for your income to decrease over time and rely more on portfolio withdrawals later.

• How do taxes affect retirement income?

  Up to 85% of Social Security can be taxable depending on total income. Traditional 401(k)/IRA withdrawals are fully taxable as ordinary income. Roth withdrawals are tax-free. A mix of account types gives you flexibility to manage your tax bracket.

• What about inflation in retirement?

  Social Security has COLA (cost-of-living adjustments). Pensions usually don't. Portfolio withdrawals should be inflation-adjusted. Healthcare costs typically rise faster than general inflation. Plan for 3% average inflation and higher for healthcare.
