How much do I need to retire? It is the most-asked question in personal finance, and the most honest answer is: it depends on how you want to live. But you do not need a financial advisor to get a useful number. With a few simple rules of thumb and an honest look at your spending, you can estimate your retirement target in about fifteen minutes.
The 25x Rule: Your Starting Number
The simplest method is the 25x rule. Take the amount you expect to spend each year in retirement and multiply it by 25. That is roughly how much you need saved. The math comes from the well-known 4% rule: if you withdraw 4% of your portfolio in the first year of retirement and adjust for inflation after that, your money has historically lasted at least 30 years.
Example: if you plan to spend $50,000 per year in retirement, you need about $1,250,000 saved. Planning on $80,000 a year? Your target is roughly $2,000,000. The rule is not perfect, but it turns a vague worry into a concrete goal.
Step 1: Estimate Your Annual Retirement Spending
This is where most people go wrong — they guess. Instead, do this properly:
- Track current spending for three months. Use your bank statements or a budgeting app. Most people underestimate by 20% or more.
- Subtract costs that disappear. Your mortgage may be paid off. You will stop saving for retirement. Commuting costs vanish.
- Add new costs. Healthcare is the big one — Fidelity estimates a 65-year-old couple needs over $300,000 for medical expenses in retirement. Travel, hobbies, and helping family also add up.
- Be honest about lifestyle. “Modest” retirement in a paid-off house in a low-cost state is very different from an active retirement with travel in a high-cost city.
Step 2: Subtract Social Security and Pensions
You do not need to fund 100% of your spending from savings. The average Social Security retirement benefit is around $1,900 per month in 2026 — about $23,000 per year. A couple might receive $35,000–$45,000 combined. Subtract your expected benefits from your annual spending need before applying the 25x rule.
Check your personal estimate at the Social Security Administration retirement estimator — it uses your actual earnings record. If you have a pension, subtract that too. Only the remaining gap needs to come from your portfolio.
Revised example: you need $60,000 per year, expect $25,000 from Social Security, so your portfolio must cover $35,000. Multiply by 25: your savings target is $875,000 — far less scary than the raw $1.5 million.
Step 3: Adjust for Your Age
The 4% rule assumes a 30-year retirement starting around age 65. Retiring at 55? You may need 30x or more. Retiring at 70 with good health? 20x might suffice. Fidelity’s retirement savings guidelines suggest aiming to have 1x your salary saved by 30, 3x by 40, 6x by 50, and 10x by 67 — useful checkpoints along the way.
What If You Are Behind?
Most people are. If your number looks impossible, you have four levers:
- Save more. Even an extra $200 a month compounds enormously over 20 years.
- Retire later. Each additional working year helps three ways: more savings, more compounding, and fewer years to fund.
- Spend less in retirement. Downsizing or relocating can cut your target dramatically.
- Earn more now. A side income dedicated entirely to retirement savings accelerates everything.
Common Mistakes to Avoid
Do not ignore inflation — $50,000 today will feel like $35,000 in twenty years at 2% inflation. Do not forget taxes — traditional 401(k) withdrawals are taxed as income. Do not assume you will spend less every year; spending often stays flat or rises with healthcare. And do not keep your retirement money in cash “to be safe” — inflation quietly destroys it.
Where to Keep Your Retirement Savings
Knowing your number is only half the battle — the money has to live somewhere productive. For most workers, the 401(k) comes first, especially if your employer matches contributions. A typical match of 50% on the first 6% of salary is an instant 50% return; turning it down is leaving free money on the table. Contribute at least enough to capture the full match before saving anywhere else.
Next, consider an IRA — traditional or Roth. A Roth IRA is powerful for younger savers: you contribute after-tax dollars, but withdrawals in retirement are tax-free, which is a remarkable deal if you expect to be in a higher bracket later. For 2026, the IRA contribution limit is $7,000 ($8,000 if you are 50 or older). High earners should note the income limits on Roth contributions and the backdoor Roth strategy.
Workers over 50 get catch-up contributions: an extra $7,500 in a 401(k) and $1,000 in an IRA beyond standard limits. If you are behind in your fifties, these exist precisely for you — use them.
Healthcare: The Budget-Buster
Healthcare deserves its own section because it surprises nearly every retiree. Before Medicare kicks in at 65, private health insurance can cost $1,000–$2,000 per month for a couple. After 65, Medicare covers a lot but not everything — premiums, deductibles, dental, vision, and hearing add up. Long-term care is the wildcard: a nursing home averages over $100,000 per year, and Medicare does not cover it. Long-term care insurance is worth evaluating in your fifties, when premiums are still reasonable.
Three Sample Scenarios
The modest retiree: Paid-off home, $40,000 annual spending, $22,000 from Social Security. Gap: $18,000. Target: $450,000. Very achievable with steady 401(k) contributions.
The comfortable couple: $75,000 annual spending, $40,000 combined Social Security. Gap: $35,000. Target: $875,000. Requires consistent saving from your thirties onward.
The active traveler: $110,000 annual spending, $35,000 Social Security. Gap: $75,000. Target: $1,875,000. Needs aggressive saving, strong market returns, or a later retirement age.
Frequently Asked Questions
Is $1 million enough to retire?
For many people, yes — especially with Social Security on top and a paid-off home. $1 million at a 4% withdrawal rate provides $40,000 per year before taxes. Whether that is enough depends entirely on your spending.
Can I retire with no savings at 65?
Social Security alone averages about $23,000 per year, which is below the poverty line for many areas once housing is factored in. It is possible to survive, but not comfortably. Even small savings help enormously.
What percentage of income should I save?
The classic advice is 15% including employer match. If you start late, 20–25% may be necessary. Automate it so you never see the money.
Revisit Your Number Every Year
Your retirement number is not a tattoo — it is a moving target. Review it annually: update your spending estimate, check your portfolio balance, and rerun the math. Life changes — raises, kids, moves, health events — all shift the target. An annual fifteen-minute check keeps you honest and lets you course-correct while there is still time.
The Bottom Line
Multiply your expected annual spending (minus Social Security) by 25. That is your number. Then work backward: how much must you save each month to get there? The answer is almost always “start now, save automatically, and invest it.” The perfect plan you never start beats the imperfect one every time — and the best time to start was ten years ago. The second-best time is today.
