How Much Do I Need to Retire? A Practical Number Without Guesswork
"How much do I need to retire?" is usually asked in dollars, but the honest answer starts in spending. A $2 million portfolio funds a very different retirement for someone who lives on $55,000 a year than for someone who lives on $110,000.
The frustrating part is that most retirement calculators ask the question backward. They ask how much you have saved, then tell you how long it might last. That is useful, but it does not tell you whether you can actually stop working. A better approach builds the number from the other end: what you will spend, what taxes and healthcare will add, and what withdrawal rate you can live with.

The practical takeaway
A retirement number is not one figure. It is a spending floor, an income bridge, a tax bill, and a healthcare line item, added up and tested against a withdrawal rate you can defend.
Start with spending, not a multiple of your salary
The most common shortcut, "aim for 10 times your final salary," is a decent benchmark and a poor plan. It ignores that a high earner who saves aggressively may spend only a third of their salary, while a moderate earner with a paid-off house and low expenses may need far less than the multiple suggests.
Write down what retirement actually costs. Use bank and credit card statements from the past 12 to 24 months rather than guessing. Separate the number into three buckets:
- Core spending: housing, utilities, groceries, insurance, property taxes, healthcare premiums, and transportation. These are hard to cut.
- Flexible spending: travel, dining, hobbies, gifts, and family help. These can rise or fall with the market and with your health.
- Irregular spending: cars, roofs, HVAC, dental work, and one-time care needs. These arrive on no schedule and wreck budgets that ignore them.
A household that thinks it spends $70,000 a year often finds $82,000 when irregular costs are averaged in. That $12,000 gap is the difference between a plan that survives and one that quietly fails.
The withdrawal rate does the heavy lifting
Once you know annual spending, the withdrawal rate turns it into a portfolio target. The 4% rule inverts to the "25x" rule: multiply annual spending by 25 to get a rough portfolio size. If you need $60,000 a year from the portfolio, the rough target is $1.5 million.
That rule is a starting point, not a contract. A retiree starting at 55 with a long horizon may want a more conservative 3.3% to 3.5% rate, which pushes the multiple toward 28x to 30x. A retiree starting at 68 with Social Security and a pension covering most core costs can often take a higher rate because the portfolio is only filling the gap.
A more useful version separates guaranteed income from the portfolio. Subtract Social Security, pensions, and any annuity income from annual spending. What is left is the amount the portfolio must cover, and that smaller number is what you multiply.
- Total annual spending: from the three buckets above.
- Minus guaranteed income: Social Security, pensions, annuities.
- Equals portfolio need: the gap your savings must fill.
- Multiply the gap by 25 to 30, depending on age and risk tolerance.
- Add a tax and healthcare buffer so the portfolio need is honest.
RetireFree's How Much to Retire planner walks through this arithmetic with your own numbers instead of a generic benchmark. If you already know the portfolio size, the Retirement Withdrawal Calculator can show the spending range it supports.
Taxes and healthcare change the number more than people expect
Two households with the same living expenses can need noticeably different portfolios because of taxes and healthcare. A couple drawing from a traditional IRA pays income tax on withdrawals, while a couple drawing from Roth and taxable accounts may owe far less on the same spending. Medicare IRMAA surcharges, based on income from two years earlier, can quietly add hundreds per month to healthcare costs.
Healthcare is its own line item, not a rounding error. Retiring before 65 means ACA premiums or COBRA until Medicare starts. After 65, Part B, Part D, a supplement or Advantage plan, dental, vision, and hearing all cost money, and out-of-pocket costs tend to rise with age. A realistic plan treats healthcare as a category that grows, not a flat number.
The cleanest fix is to build the portfolio need in after-tax, after-healthcare dollars. If that means the number comes out higher than a naive 25x calculation, that is the point. A number you can trust beats a smaller number that only looks good on paper.
Work backward from a real example
Take a 62-year-old couple who spend $80,000 a year in today's dollars, own their home, and expect $45,000 a year in combined Social Security at their planned claiming ages. The gap is $35,000 a year, plus maybe $12,000 for taxes and healthcare above what Medicare covers, so the portfolio needs to produce roughly $47,000 a year. At a conservative 3.5% withdrawal rate, that points to around $1.34 million.
Change one assumption and the answer moves. If they delay Social Security to 70 and need to bridge eight years of full living costs from savings, the portfolio need jumps for those years. If one spouse retires three years before the other, guaranteed income and healthcare change again. This is exactly why the number deserves a plan, not a spreadsheet cell.
Where you live also moves the arithmetic. State income taxes, property taxes, and housing costs vary widely, and a move can shift the number by six figures. That is a topic worth researching before you commit to a target.

Bottom line
The retirement number you can trust is built from spending, not from a salary multiple. Add up real costs, subtract guaranteed income, test the gap against a withdrawal rate, and give taxes and healthcare their own line items. It is more work than a benchmark, but it is the difference between a target you can defend and a guess you have to keep second-guessing.

Frequently asked questions
Is the 25x rule still a good retirement target?
It is a reasonable starting point for a 30-year retirement at a 4% withdrawal rate. For longer horizons or a lower risk tolerance, a higher multiple such as 28x to 30x is more conservative. The best number always comes from your own spending and guaranteed income, not the rule alone.
Do I need $2 million to retire?
Only if your portfolio needs to produce around $60,000 to $80,000 a year beyond Social Security and other guaranteed income. Many households retire comfortably on far less when core costs are covered by guaranteed income, while others need more because of high housing, healthcare, or tax costs.
How does retiring early change the number?
It raises it, for two reasons. The portfolio must last longer, which argues for a lower withdrawal rate, and the years before Medicare and Social Security require bridging full living costs and healthcare from savings.
