How Much to Retire: The Number That's Actually Right for You

It's the question everyone asks. And almost everyone gets wrong.

How much do you need to retire?

It's the question everyone asks. And almost everyone gets wrong.

Financial advisors will tell you a number—often $1 million, $2 million, more. Online calculators will give you a number based on assumptions that may not match your life. Your neighbor will tell you their number, which may have nothing to do with yours.

Here's the truth: there's no single right number. The amount you need depends on your specific situation, your specific desires, and your specific definition of a good life.

The Traditional Approach (And Its Problems)

The traditional retirement planning approach goes something like this:

  1. Estimate your annual expenses in retirement
  2. Multiply by 25 (the "4% rule")
  3. That's your number

If you think you'll need $60,000/year, multiply by 25 = $1.5 million.

This approach has value—it's a starting point. But it has major problems:

Problem 1: It Assumes Static Expenses

In reality, your expenses will change. Healthcare costs may increase. Housing costs may change. Family obligations may arise.

Problem 2: It Ignores Taxes

Unless you're in a Roth-only retirement, you'll pay taxes. This can be 15-30% or more of your withdrawals.

Problem 3: It Doesn't Account for Big Expenses

One-time costs—home repairs, weddings, grandchild support—can blow up the math.

Problem 4: It Ignores Flexibility

The best retirement plans have flexibility built in. You don't need a fixed income; you need options.

A Better Framework

Instead of a single number, think in ranges and scenarios.

Step 1: Define Your Retirement Lifestyle

What does your ideal retirement look like?

Lean retirement ($40-50k/year):

  • Basic living expenses
  • Modest travel
  • Limited extras

Comfortable retirement ($60-80k/year):

  • Comfortable housing
  • Regular travel
  • Some hobbies and extras

Luxury retirement ($100k+/year):

  • Premium housing
  • Extensive travel
  • Multiple hobbies
  • Support services

Be honest about which category matches your vision.

Step 2: Calculate Your Essential Expenses

What expenses are truly non-negotiable?

  • Housing (mortgage/rent, utilities, maintenance)
  • Healthcare (premiums, out-of-pocket, insurance)
  • Food
  • Transportation
  • Basic necessities

This is your floor—the minimum you need to survive.

Step 3: Add Your Lifestyle Expenses

What do you want to do in retirement?

  • Travel
  • Hobbies
  • Dining out
  • Entertainment
  • Support services (cleaning, gardening)
  • Gifts
  • Family support

Add these to your essentials.

Step 4: Factor in the Unknowns

What might change?

  • Healthcare inflation
  • Long-term care needs
  • Home repairs
  • Unexpected family needs

Add a buffer—typically 20-30%.

Step 5: Build Your Scenarios

Now create multiple scenarios:

Base case: Your expected expenses, expected lifespan, expected returns

Stress case: Higher expenses, longer lifespan, lower returns

Best case: Lower expenses, shorter lifespan, higher returns

Goal: Even in the stress case, you should be okay.

The Income Side

The expense side is only half the equation. What about income?

Social Security

Estimate your benefits at ssa.gov. Remember:

  • Benefits increase if you wait until 70
  • Benefits are reduced if you claim at 62

Pensions

If you have a pension, that's huge. It's guaranteed income that reduces your portfolio burden.

Part-Time Work

If you can earn even modest income in retirement, it dramatically reduces your portfolio needs.

$20,000/year in part-time work:

  • Reduces portfolio needs by $500,000 (at 4%)
  • Provides structure and purpose
  • Extends your savings by years

Portfolio Withdrawals

This is the main source for most people. The 4% rule is a reasonable starting point, but remember:

  • The rule assumes a 30-year retirement
  • It's based on historical returns, which may not repeat
  • Flexibility (reducing spending in bad years) improves success rates

The "Right" Number

Here's my framework for finding your right number:

The Minimum

What do you need to cover essentials if everything goes wrong?

  • Lower Social Security
  • Minimal expenses
  • No help from family

This is your floor. Build to at least this level.

The Target

What do you need for the retirement you actually want?

  • Your vision of a good life
  • Room for extras
  • Some buffer for unknowns

This is your goal.

The Cushion

How much buffer do you want?

  • 10-20% above your target?
  • Or more?

This is your comfort zone.

Common Mistakes

Mistake 1: Underestimating Healthcare

Healthcare is the wildcard. Medicare isn't free. Long-term care can cost $100,000+/year. Plan for this.

Mistake 2: Ignoring Taxes

Taxes don't disappear in retirement. Plan for them.

Mistake 3: Not Accounting for Inflation

Healthcare inflation has historically outpaced general inflation. Factor this in.

Mistake 4: Being Too Conservative

Yes, you need to plan for adversity. But being too conservative means working longer than necessary.

Mistake 5: Being Too Aggressive

On the flip side, underestimating risks can lead to running out of money. Balance is key.

A More Personal Approach

Here's a different way to think about it:

Instead of "how much do I need?" ask:

"What do I want my life to look like, and what does that cost?"

Then work backward:

  • What income sources do I have?
  • What's the gap?
  • How do I close it?

This approach is more personal, more motivating, and more likely to lead to a plan you'll actually follow.

The Bottom Line

There's no single right number. There's only the right number for you—based on your desires, your situation, and your definition of a good life.

Don't get hung up on a target that may not match your reality. Instead:

  1. Define your vision
  2. Calculate your needs
  3. Assess your resources
  4. Build scenarios
  5. Create flexibility

The "right" number is the one that lets you live the life you want—without constant fear of running out.
