The most common question in retirement planning is also the most important: "How much money do I actually need to retire?"
The answer isn't one-size-fits-all, but this guide will help you calculate your personal retirement number and create a plan to reach it.
📊 The Quick Answer: Popular Rules of Thumb
Before we dive deep, here are the most common retirement planning benchmarks:
The 4% Rule
The 4% rule suggests you can safely withdraw 4% of your retirement savings each year without running out of money. To calculate how much you need:
Retirement Savings Needed = Annual Expenses ÷ 0.04
Example: If you need $60,000 per year in retirement:
- $60,000 ÷ 0.04 = $1,500,000
This means you'd need $1.5 million to retire using the 4% rule.
The 25x Rule
This is simply the inverse of the 4% rule. Multiply your annual expenses by 25:
Retirement Savings = Annual Expenses × 25
Example: $60,000 × 25 = $1,500,000
Same result, different calculation method.
The Salary Multiplier Method
Financial advisors often recommend having 10-12x your final salary saved by retirement:
- Age 30: 1x your salary
- Age 40: 3x your salary
- Age 50: 6x your salary
- Age 60: 8x your salary
- Age 67: 10-12x your salary
Example: If you earn $100,000 when you retire, aim for $1-1.2 million in savings.
⚠️ Why These Rules Aren't Perfect
While these rules provide helpful benchmarks, they have limitations:
The 4% Rule Assumes:
- 30-year retirement period
- Traditional 60/40 stock/bond portfolio
- No major market crashes early in retirement
- Consistent annual spending
- No major healthcare emergencies
Reality: Your actual safe withdrawal rate might be 3.5% (more conservative) or 5% (more aggressive), depending on your situation.
Factors That Change Your Number
Your personal retirement number depends on these variables:
1. Retirement Age
- Retire at 55: Need enough for 30-40 years
- Retire at 70: Need enough for 15-25 years
- Earlier retirement = need significantly more
2. Lifestyle and Expenses
- Frugal retirement ($40k/year): ~$1 million needed
- Moderate retirement ($70k/year): ~$1.75 million needed
- Luxury retirement ($120k/year): ~$3 million needed
3. Social Security Benefits
- Average benefit: ~$1,900/month ($22,800/year)
- Maximum benefit: ~$3,800/month ($45,600/year)
- This reduces how much you need to save
4. Healthcare Costs
- Medicare starts at 65
- Average couple needs $300,000 for healthcare in retirement
- Long-term care can add $100,000-$500,000+
5. Inflation
- 3% inflation doubles costs every 24 years
- Your money needs to last AND grow
6. Geographic Location
- Rural Tennessee: $50k/year comfortable
- San Francisco: $100k/year barely enough
- International retirement: Varies widely
🧮 Calculating Your Personal Retirement Number
Let's walk through a realistic calculation:
Step 1: Estimate Annual Retirement Expenses
Start with your current annual spending and adjust:
Current Annual Expenses: $85,000
Adjustments:
- No more mortgage: -$18,000
- No more 401(k) contributions: -$12,000
- Healthcare increases: +$8,000
- More travel: +$10,000
- No commuting: -$3,000
Estimated Retirement Expenses: $70,000/year
Step 2: Calculate Expected Social Security
Visit the Social Security Administration website and get your estimate. Let's assume:
Social Security: $28,000/year (starting at age 67)
Step 3: Determine Gap to Fill
Annual Gap: $70,000 - $28,000 = $42,000/year needed from savings
Step 4: Apply the 25x Rule
Retirement Savings Needed: $42,000 × 25 = $1,050,000
Step 5: Add Safety Buffers
Add 10-20% for unexpected expenses:
Target Retirement Savings: $1,050,000 × 1.15 = $1,207,500
Recommendation: Aim for $1.2-1.3 million
🔥 The FIRE Movement Approach
Financial Independence, Retire Early (FIRE) followers use a more aggressive calculation:
Formula: Annual Expenses × 25-33 (using 3-4% withdrawal rate)
Ultra-conservative FIRE: Annual Expenses × 33 (3% withdrawal) Standard FIRE: Annual Expenses × 25 (4% withdrawal)
Example for $50,000/year expenses:
- Conservative: $50,000 × 33 = $1,650,000
- Standard: $50,000 × 25 = $1,250,000
Use our FIRE Calculator to determine your FIRE number and years until financial independence.
📈 How Much Should You Have Saved by Age?
Here's what the data shows for different age groups:
Age 30
- Minimum: 1x annual salary
- Target: 1.5x annual salary
- Stretch Goal: 2x annual salary
Example at $75k salary: $75k - $150k
Age 40
- Minimum: 3x annual salary
- Target: 4x annual salary
- Stretch Goal: 5x annual salary
Example at $100k salary: $300k - $500k
Age 50
- Minimum: 6x annual salary
- Target: 7x annual salary
- Stretch Goal: 8x annual salary
Example at $120k salary: $720k - $960k
Age 60
- Minimum: 8x annual salary
- Target: 10x annual salary
- Stretch Goal: 12x annual salary
Example at $130k salary: $1.04M - $1.56M
Age 67 (Full Retirement)
- Minimum: 10x annual salary
- Target: 12x annual salary
- Stretch Goal: 15x annual salary
Example at $130k salary: $1.3M - $1.95M
❌ Common Retirement Number Mistakes
Mistake #1: Forgetting About Taxes
Your $1 million in a traditional 401(k) isn't really $1 million. You'll pay taxes on withdrawals.
Solution:
- Assume 15-25% tax on traditional retirement account withdrawals
- Consider Roth conversions to create tax-free income
Mistake #2: Underestimating Healthcare
Medicare doesn't cover everything. Plan for:
- Medicare premiums ($170+/month per person)
- Supplemental insurance ($100-300/month)
- Out-of-pocket costs ($3,000-6,000/year)
- Dental and vision (not covered by Medicare)
- Long-term care insurance or self-funding
Mistake #3: Ignoring Inflation
What costs $60,000 today will cost:
- $81,000 in 15 years (3% inflation)
- $108,000 in 25 years
- $145,000 in 35 years
Solution: Your investments must grow to keep pace with inflation.
Mistake #4: Planning for the Average
You might live longer than average. Plan for:
- 30-40 year retirement if retiring at 60
- Possibility of living to 95-100
- Higher healthcare costs in later years
Mistake #5: All-or-Nothing Thinking
You don't need the full amount saved before you stop working. Options include:
- Phased retirement (part-time work)
- Consulting or freelancing
- Starting a small business
- Geographic arbitrage (move somewhere cheaper)
🚀 Strategies to Reach Your Number Faster
Strategy #1: Increase Savings Rate
Every 1% increase in savings rate can reduce working years by 1-2 years.
Current: Saving 15% ($15k/year on $100k salary) Goal: Save 25% ($25k/year) Impact: Retire 5-7 years earlier
Strategy #2: Maximize Tax-Advantaged Accounts
Priority order:
- 401(k) to employer match (free money)
- HSA if eligible (triple tax advantage)
- Roth IRA (tax-free growth)
- Max out 401(k) ($23,000 in 2025)
- Taxable brokerage account
Strategy #3: Reduce Investment Fees
A 1% fee difference can cost hundreds of thousands over a career.
Example over 30 years with $500k:
- 0.05% fee (index funds): Costs $50,000
- 1.05% fee (active funds): Costs $325,000
- Difference: $275,000 lost to fees
Use our Investment Fee Calculator to see how fees impact your retirement.
Strategy #4: Plan for Lower Expenses
Many expenses naturally decrease in retirement:
- No more mortgage (if paid off)
- No commuting costs
- Lower clothing expenses
- No retirement savings contributions
- Potential to downsize home

Frequently Asked Questions
Q: Is $1 million enough to retire?
A: It depends on your expenses and Social Security. Using the 4% rule, $1 million provides $40,000/year. If you also get $25,000 from Social Security, that's $65,000 total - comfortable for many people but not enough for expensive areas or luxurious lifestyles.
Q: Can I retire at 55 with $2 million?
A: Probably yes. $2 million supports $80,000/year using the 4% rule. However, you'll need to bridge healthcare until Medicare at 65, and your money needs to last 30-40 years. Consider a 3.5% withdrawal rate ($70,000/year) for added safety.
Q: How much should I have saved by 35?
A: Target 1.5-2x your annual salary. If you earn $80,000, aim for $120,000-160,000 in retirement savings.
Q: What if I'm behind on retirement savings?
A: You have options:
- Increase savings rate dramatically (save 25-30%)
- Work a few extra years (each year adds ~10% more funds)
- Plan for lower retirement expenses
- Consider part-time work in retirement
- Delay Social Security to age 70 for 24% higher benefits
Q: Should I pay off my house or save for retirement?
A: Do both if possible. Prioritize 401(k) match first, then split between mortgage payoff and retirement savings. Entering retirement debt-free dramatically reduces the amount you need.
Q: How do I account for inflation in retirement planning?
A: Assume 3% annual inflation. This means expenses double roughly every 24 years. Your investment returns need to exceed inflation to maintain purchasing power.
Q: What's a safe withdrawal rate?
A: The traditional 4% rule has been challenged recently. Many experts now recommend:
- 3.5% for 40-year retirements
- 4% for 30-year retirements
- 4.5% for 20-year retirements
Q: Do I need less money if I retire later?
A: Yes, significantly less. Every year you delay retirement means:
- One less year of retirement expenses
- One more year of savings and growth
- Higher Social Security benefits (if delaying past 62)
- Less time for money to last
