How Much Money Do You Really Need to Retire in 2026? (Calculate Your Number)

Financial planner William Bengen's 1994 research established what is now called the 4% rule: withdraw 4% of your retirement portfolio in year one, then adjust that dollar amount for inflation each following year, and historically your money lasts through a 30-year retirement with low risk of running out.

The math is simple. Multiply your desired annual retirement income by 25. Want $40,000 per year in retirement? You need $1,000,000. Want $60,000 per year? You need $1,500,000. Want $80,000 per year? You need $2,000,000.

This single calculation is the foundation almost every retirement plan starts with, yet most people have never actually run their own numbers.

The internet loves to throw around round numbers like "you need a million dollars." The truth is your number depends entirely on your desired lifestyle, other income sources, and how long you expect to live in retirement.

If you will receive Social Security of $2,000 per month, that's $24,000 per year you don't need to withdraw from savings. Your target drops accordingly. If you plan to downsize your home and free up $200,000 in equity, that reduces your number too. If you want to travel extensively in early retirement, your number needs to go up.

Let's say you're 35 years old, want to retire at 65 with $60,000 per year in today's dollars, and expect $20,000 annually from Social Security. Your investment portfolio needs to cover the remaining $40,000 per year. Using the 4% rule: $40,000 × 25 = $1,000,000 needed at retirement. If you currently have $50,000 saved and can contribute $800 per month with an average 8% annual return, you'd reach approximately $1,190,000 by age 65 — comfortably above your target.

Starting early is worth more than almost any other retirement decision you can make. Consider three people who all eventually invest the same total amount.

Someone contributing $400/month starting at age 25 and stopping at 35 (just 10 years of contributions, then letting it grow untouched) often ends up with more money by 65 than someone who starts contributing the same $400/month at age 35 and continues for 30 straight years.

This is the entire argument for starting now rather than waiting until you "have more money to invest properly." Time in the market consistently outperforms trying to invest larger amounts later.

Employer 401k match first — always. If your employer matches 50% up to 6% of your salary, that's an immediate 50% return the moment you contribute. No investment anywhere matches that guaranteed return.

Roth IRA next, up to the annual limit, especially if you're in a lower tax bracket now than you expect to be in retirement. Withdrawals in retirement are completely tax-free. Then back to 401k beyond the match if you have room, or a taxable brokerage account for additional flexibility.

Inside these accounts, low-cost total market index funds remain the most evidence-backed choice for long-term growth, historically outperforming the majority of actively managed funds after fees.

If your calculation shows a shortfall, you have more options than you might think. Increasing your monthly contribution by even $100 makes a larger difference than most people expect over 20+ years due to compounding.

Delaying retirement by just 2-3 years dramatically improves outcomes since you're both contributing longer and withdrawing for fewer years. Reducing planned retirement spending by trimming your target lifestyle lowers your required number directly. And working part-time in early retirement, even earning $15,000-$20,000 per year, significantly reduces how much your portfolio needs to cover.

Every input matters — your current age, target retirement age, current savings, monthly contribution, and expected return all combine to determine whether you're on track. Use our free retirement calculator to plug in your real numbers and see your personalized projection.
