How Much Money Do You Actually Need to Retire?

The 25x Rule: Your Starting Point

The most widely cited retirement target comes from the "4% rule" — the idea that you can withdraw 4% of your portfolio each year in retirement without running out of money over a 30-year period.

Flip that around: you need about 25 times your annual retirement spending in savings.

Example: If you expect to spend $50,000 per year in retirement, you need approximately $1.25 million ($50,000 × 25).

This Is a Starting Point, Not a Ceiling

The right number depends on:

• •Your expected lifespan — retiring at 55 means a longer runway than retiring at 65


• •Social Security income — your benefit reduces how much your portfolio needs to cover


• •Healthcare costs — often the biggest wildcard in retirement planning


• •Lifestyle expectations — what does your ideal retirement actually cost?


• •Other income sources — pension, part-time work, rental income

  A More Personalized Calculation

  1. 1.
  2. 2.Estimate your annual retirement expenses (in today's dollars)
  3. 3.Subtract expected Social Security income (check ssa.gov for your estimate)
  4. 4.Multiply the gap by 25
  5. 5.That's your portfolio target

     If you plan to spend $60,000/year and Social Security will cover $20,000, your portfolio needs to produce $40,000/year → target is $1 million.

     What If You're Behind?

     Most people are. The good news is that the math is more forgiving than it seems:

  
  
  6. •Working 2–3 extra years makes an enormous difference (more contributions + more growth + shorter withdrawal period)
  
  
  7. •Reducing planned retirement spending lowers the target significantly
  
  
  8. •Part-time work in early retirement can dramatically extend portfolio life
  
  
  9. •Look at the Late Start calculator to get your numbers.

     The Most Important Step: Start Now

     Time is the most powerful variable. Someone who invests $500/month starting at 30 ends up with significantly more than someone who invests $1,000/month starting at 45 — even though the second person invested more money total. Compound growth rewards patience above everything else.
