How Much Money Do I Need to Retire?
Key Takeaways:
Your retirement number starts with spending. Estimate the life you actually want to fund: the recurring bills, the discretionary choices, the irregular purchases, and healthcare costs that shift as you age.
Your portfolio only has to cover the gap. Subtract your dependable, after-tax income from what you plan to spend, and remember the early bridge years before delayed benefits kick in.
Your answer is a range, and it should be stress-tested. Test your savings against a long life, inflation, a rough market, care costs, and how much spending you could trim in a pinch.
How much money you need to retire is one of the most common questions in retirement planning, and two households with the same balance can still end up with very different retirements.
One reason the number is so personal is that it has to last a long, uncertain time. A 65-year-old today can expect to live into their mid-80s on average, and roughly one in four will pass 90,1 so your savings may need to cover 25 or 30 years. What you’ll actually need comes down to the life you want, the dependable income you’ll have, and how much your portfolio has to supply, with taxes, healthcare, and inflation shaping all of it.
Build a Retirement Spending Estimate Around the Life You Want
Start from how you spend now, then adjust each category for the years ahead, in concrete numbers:
Core living costs: Housing, property taxes, utilities, groceries, transportation, insurance, and any debt payments. Drop commuting and debts that will end, but don’t assume every cost falls when the paychecks stop. This is your baseline.
Lifestyle goals: Travel, hobbies, dining, memberships, charitable giving, a second home, family support. Build in the life you actually want here, rather than a stripped-down version designed to produce a smaller number.
Irregular and large expenses: Home repairs, a replacement car, appliances, dental work, milestone trips. Spread these across the years or set up a reserve, so one big purchase doesn’t blow up a single year’s estimate.
Healthcare costs: Coverage before Medicare, Medicare premiums, supplemental or Advantage coverage, prescriptions, deductibles, and dental, vision, and hearing. Leave room for personal support or long-term care later on.
Spending that shifts over time: The early, active years often cost more, then taper as you slow down, while healthcare and care costs climb later. One flat number can hide those swings.
Determine How Much of Your Spending the Portfolio Must Cover
What you’ll spend and what your portfolio has to produce are two different numbers. Subtract the steady income you’ll have, from Social Security, a pension, or part-time work, from your projected spending, and whatever’s left is the gap your savings have to fill.
Subtract the Retirement Income You Can Depend On
List each reliable stream, when it starts, and whether it changes over time. Treat anything uncertain cautiously, so your plan doesn’t lean on income that might not show up.
The common dependable sources each need their own assumptions:
Claiming strategy: Use a personalized Social Security estimate tied to the ages you’re weighing. For a couple, compare each spouse’s benefit and what would be left to a survivor, rather than just adding two lifetime checks together.2
Pension election: Use the payout for the option you’d actually choose, and check whether it adjusts for inflation and how much continues after one spouse dies.
Continued work: Count part-time work, consulting, or business income only if you truly expect it to last, and give temporary work a firm end date.
Rental cash flow: Count rent after vacancies, repairs, financing, management, and operating costs. Gross rent overstates what you can actually spend.
Please Note: Put each income source on a timeline, and keep what you can tap right away separate from what only starts later. That timing is what decides which years lean hardest on your savings.
Adjust the Portfolio Income Gap for Taxes
The cash you need to spend and the amount you have to withdraw aren’t the same. Federal and California taxes can open a meaningful gap between a gross withdrawal and what lands in your checking account. Withdrawals from traditional retirement accounts are generally taxable, while qualified Roth withdrawals are generally tax-free, and a taxable brokerage account throws off its own interest, dividends, and gains, so two equal balances can spend very differently.3
Pension payments, taxable Social Security, investment income, and account withdrawals can all land in the same year and push each other around. Build your gap around the after-tax number you actually need, using a reasonable estimate of the taxes your withdrawal mix will create.4
Turn the Annual Portfolio Need Into a Personalized Retirement Savings Range
Your annual gap is just the starting input. A year-by-year projection has to account for when you take withdrawals, when your dependable checks start, and how spending and inflation move over time.
From there, the analysis estimates how much your investments can provide while keeping enough capital for later. Your retirement age, life expectancy, asset mix, fees, inflation, expected return, and spending flexibility all move the result.
The output is a range. The low end supports your plan under reasonable assumptions with less margin for error, while the high end leaves room for optional spending, surprises, or more cautious withdrawals.
Example of Calculating a Retirement Savings Range
Say you expect to spend about $95,000 a year after taxes. Once Social Security and your pension are flowing, you expect $55,000 of dependable income, which leaves a $40,000 annual gap for the portfolio to fill.
The early years can demand more. If one benefit starts five years in, the plan may have to cover well above $40,000 at first, which raises the amount you need at retirement.
Model that gap across different retirement lengths, inflation assumptions, and return sequences, keeping spending and income in the same dollar basis. That’s what turns a single gap number into a realistic range.
Decide Whether You Are Financially Ready to Retire
Hitting a number on paper isn’t the same as being ready. Your resources have to hold up through weak markets, rising costs, and a retirement that runs longer than you planned.
Stress-Test the Risks That Could Raise the Amount You Need
A strong projection leans on more than one average path. Each of these risks bites differently depending on when it hits and how much flexibility you’ve kept.
Run your plan against these pressure points:
Longevity: Test well past average life expectancy, especially if you retire early or one spouse may outlive the other by years.
Inflation: Check whether your withdrawals and dependable income keep their purchasing power if housing or medical costs climb faster than expected.
Sequence of returns: Model a market drop right around your retirement date, when selling into losses can leave far less invested for the recovery.
Healthcare and long-term care: Test higher medical costs and an extended care event, including one where a spouse’s needs reshape the whole budget.
Income disruption: Model losing a spouse’s benefit, a pension change, a rental gap, or paid work ending sooner than planned.
Limited flexibility: Separate the fixed costs from the travel, gifts, and big purchases you could actually cut in a tough stretch.
Compare the Target Range With the Resources You Have
Now hold the range up against what you’ve actually got, and pay attention to the mix and accessibility, not just the total.
Work through a few practical questions:
Add up your workplace plans, traditional and Roth Individual Retirement Accounts (IRAs), taxable brokerage accounts, and any cash set aside for retirement.
Leave out your home and personal property unless your plan actually involves selling, downsizing, or borrowing against them.
Compare the after-tax spending power of your taxable, tax-deferred, and Roth money, rather than the headline balances.
Figure out whether you have a meaningful margin above the range, sit near the bottom of it, or face a shortfall.
Know your levers: saving more, working a bit longer, shifting your date, trimming optional costs, delaying benefits, part-time income, or rethinking housing.
Revisit the whole analysis after any major change in spending, work, health, marriage, tax law, benefits, or account balances.
