“How much money do you need to retire?” is one of the most-searched retirement questions there is, and one of the most frustrating, because the answers are all over the map. One article says $1 million. Another says ten times your salary. A third says it depends.
The honest answer is that it does depend, but not in a vague way. It depends on a few specific numbers that you can find. This guide walks you through a simple four-step method to estimate how much money you need to retire, based on your own life instead of someone else’s average.
Why there’s no single number
Two people with the same income can need very different amounts. One plans to travel; the other plans to garden. One has a pension; the other doesn’t. One has a paid-off home; the other has a mortgage.
For a sense of scale: according to the Bureau of Labor Statistics, households headed by someone 65 or older spent an average of about $61,400 in 2024. That’s a useful reference point, but your number could be far above or below it. That’s why the method below starts with you.
Step 1: Estimate what you’ll spend in retirement
Start with what you spend today, not what you think you spend. The easiest way is to add up a full year of bank and credit card statements, so you catch irregular costs like car repairs, gifts, and insurance premiums.
Then adjust for retirement:
- Costs that often go down or disappear: commuting, work clothes, retirement contributions, and possibly a mortgage if it’s paid off.
- Costs that often go up: travel and hobbies (especially early in retirement), and healthcare. If you retire before 65, you’ll need to pay for health coverage until Medicare starts.
The result is your estimated yearly retirement spending.
Step 2: Add up your guaranteed income
Next, list the income you can count on in retirement:
- Social Security. Get your estimates at ssa.gov/myaccount. Your benefit depends on when you claim, anywhere from 62 to 70. Social Security also adjusts for inflation each year; benefits are rising 3.6% in January 2027.
- A pension, if you have one.
- Annuity payments, if you have them.
- Part-time work you’re confident you’ll do, at least for the first few years.
The total is your yearly guaranteed income.
Step 3: Find your gap
Subtract your guaranteed income from your spending:
Yearly spending − Yearly guaranteed income = Your yearly gap
The gap is the amount your savings will need to cover each year. For many people, this is the most clarifying number in their entire plan. If your guaranteed income covers all of your spending, your gap is zero, and your savings become a cushion for emergencies, one-time costs, and goals.
Step 4: Turn your gap into a savings target
A common rule of thumb is to multiply your yearly gap by 25. That comes from the “4% rule,” a guideline based on historical research suggesting that withdrawing about 4% of your savings in the first year, then adjusting for inflation, has historically lasted about 30 years in most periods.
Yearly gap × 25 = Rough savings target
Then add a cushion for big one-time expenses you can see coming, such as a new roof, a car, or helping family.
This gives you a starting estimate, not a guarantee. Markets, taxes, inflation, and how long you live can all change it, so think of it as a target to plan around, not a pass/fail line.
How much money do you need to retire? A worked example
Here’s a made-up couple, both 63, planning to retire in a few years.
| Monthly | Yearly | |
|---|---|---|
| Spending today | $5,800 | $69,600 |
| Minus costs that end (commuting, retirement contributions) | −$700 | −$8,400 |
| Plus costs that rise (travel, healthcare) | +$400 | +$4,800 |
| Estimated retirement spending | $5,500 | $66,000 |
| Social Security (both spouses, from their statements) | $3,900 | $46,800 |
| Small pension | $400 | $4,800 |
| Guaranteed income | $4,300 | $51,600 |
| Gap savings must cover | $1,200 | $14,400 |
Their rough savings target: $14,400 × 25 = $360,000. Add about $40,000 for a future car and roof replacement, and they’re looking at roughly $400,000.
That’s very different from “$1 million,” and far more useful, because it’s based on their actual life. Their real number could be higher once taxes on withdrawals are included, which is one reason a tax professional or fee-only planner can be worth a conversation.
What can change your number
How much money do you need to retire? The answer can shift a lot depending on these factors:
- When you retire. Retiring earlier means more years to fund and possibly paying for health coverage before 65.
- When you claim Social Security. Claiming later generally means a larger monthly benefit for life, which shrinks your gap.
- How long you live. Planning only to your life expectancy can leave you short if you live longer. Many planners suggest planning into your 90s.
- Inflation. Prices rise over time. Social Security adjusts each year, but your savings withdrawals need to rise too.
- Taxes. Withdrawals from traditional IRAs and 401(k)s are generally taxed as income, and some people pay tax on part of their Social Security.
- Housing. A paid-off home, a move, or downsizing can change your spending more than almost anything else.
- Healthcare and long-term care. These are among the largest and least predictable costs in retirement.

Rules of thumb, and their limits
- “You’ll need 70% to 80% of your pre-retirement income.” A rough starting point, but it can be far off if your spending changes a lot in retirement, or if you’re saving a large share of your income today.
- “The 4% rule.” Useful for a ballpark estimate. It’s based on historical results, not a guarantee, and some planners use a lower or higher rate depending on retirement age, investments, and flexibility.
- “Save 10 times your salary.” Easy to remember, but it ignores pensions, Social Security timing, and what you actually spend.
Rules of thumb are fine for a first look. Your own numbers are better.
If your number looks too big
Don’t panic. A big gap is information, not a verdict, and you have more options than it may seem. People commonly close a gap by:
- Working a little longer, even part-time
- Delaying Social Security to increase their monthly benefit
- Lowering planned spending, or trimming costs today to save more
- Using catch-up contributions if they’re 50 or older
- Rethinking housing, such as downsizing or moving somewhere less expensive
Each option has tradeoffs, and the right mix depends on your situation. A fee-only financial planner can help you compare them.
Frequently asked questions
How much money do you need to retire at 65? It depends on your spending and guaranteed income. Use the four steps above: estimate spending, subtract Social Security and any pension, then multiply the yearly gap by about 25 for a rough savings target.
Is $1 million enough to retire? For some people it’s more than enough; for others it isn’t. Using the 4% guideline, $1 million might support about $40,000 a year in withdrawals, on top of Social Security and any pension. Whether that’s enough depends on what you spend.
Is the 4% rule still a good guideline? It’s a reasonable starting point for estimates, but it isn’t a guarantee. Many people adjust it based on their retirement age, investments, and how flexible their spending can be.
