❓ Frequently Asked Questions
Why does Dave Ramsey assume a 7% annual return?
Dave Ramsey uses 7% as the expected long-term average return for stock market investments, specifically adjusted for inflation.
THE 7% CALCULATION:
• Historical S&P 500 average: ~10-11% annually
• Average inflation rate: ~3% annually
• Real (inflation-adjusted) return: ~7%
WHY THIS MATTERS:
• 10% nominal return sounds great, but inflation erodes purchasing power
• $1 million in 30 years won't buy what $1 million buys today
• 7% gives you the "real" growth in purchasing power
DAVE RAMSEY'S REASONING:
• Based on historical data from 1928 to present
• Accounts for market ups and downs
• Provides a realistic planning number
• Conservative enough for retirement planning
IMPORTANT CAVEATS:
• Past performance doesn't guarantee future results
• Individual years vary dramatically (-37% to +54%)
• Long-term consistency is the key assumption
• Requires staying invested through market downturns
What is the 4% rule and how does it work?
The 4% rule is a retirement withdrawal strategy developed by financial planner William Bengen in 1994.
THE BASIC RULE:
• Withdraw 4% of your portfolio in year 1 of retirement
• Adjust that amount for inflation each subsequent year
• Your money should last at least 30 years
EXAMPLE ($1,000,000 portfolio):
• Year 1: Withdraw $40,000 (4%)
• Year 2: Withdraw $41,200 (adjusted for 3% inflation)
• Year 3: Withdraw $42,436 (compounding adjustments)
• Continue annually, adjusting for inflation
WHY 4% WORKS:
• Based on historical worst-case scenarios
• Assumes 50/50 stock/bond portfolio
• Accounts for market crashes and recoveries
• Trinity Study confirmed it historically
MODERN CONSIDERATIONS:
• Some experts now suggest 3.5% for longer retirements
• Others argue 4.5% is safe for shorter periods
• Flexibility helps: reduce spending in bad markets
• Social Security can supplement income
DAVE RAMSEY'S VIEW:
• Uses 4% as a conservative guideline
• Emphasizes becoming debt-free first
• Recommends living on less than you make
• Suggests having paid-off home by retirement
How does compound interest work in long-term investing?
Compound interest is often called the "8th wonder of the world" and is the foundation of Dave Ramsey's wealth-building strategy.
HOW IT WORKS:
• Year 1: You earn interest on your principal
• Year 2: You earn interest on principal + last year's interest
• Year 3+: Interest earns interest, creating exponential growth
COMPOUND INTEREST EXAMPLE ($10,000 at 7%):
• Year 5: $14,026 (+$4,026)
• Year 10: $19,672 (+$9,672)
• Year 20: $38,697 (+$28,697)
• Year 30: $76,123 (+$66,123)
• Year 40: $149,745 (+$139,745)
THE POWER OF TIME:
• More time = dramatically more money
• Starting at 25 vs 35 can DOUBLE your wealth
• $500/month for 40 years at 7% = $1.2 million
• $500/month for 30 years at 7% = $586,000
DAVE RAMSEY'S BABY STEPS:
1. $1,000 emergency fund
2. Pay off all debt (except house)
3. 3-6 months emergency fund
4. Invest 15% of income
5. Save for kids' college
6. Pay off house early
7. Build wealth and give
What types of investments does Dave Ramsey recommend?
Dave Ramsey recommends a specific investment strategy focused on growth-oriented mutual funds.
DAVE'S RECOMMENDED PORTFOLIO:
• 25% Growth funds
• 25% Growth and Income funds
• 25% Aggressive Growth funds
• 25% International funds
WHY MUTUAL FUNDS:
• Professional management
• Instant diversification
• Lower risk than individual stocks
• Proven long-term performance
WHAT TO AVOID:
• Individual stocks (too risky)
• Bonds (lower returns for younger investors)
• Whole life insurance (bad investment vehicle)
• Variable annuities (high fees)
• Gold and precious metals
WHERE TO INVEST:
• Employer 401(k) with match (free money!)
• Roth IRA (tax-free growth)
• Traditional IRA if no 401(k) match
• HSA if eligible (triple tax advantage)
INVESTMENT ORDER:
1. Get 401(k) match (100% return!)
2. Max out Roth IRA ($7,000/year in 2024)
3. Go back to 401(k) up to 15% of income
4. Taxable brokerage if you can invest more
When should I start investing according to Dave Ramsey?
Dave Ramsey has specific prerequisites before you should start investing, outlined in his "Baby Steps" plan.
BEFORE INVESTING (Baby Steps 1-3):
1. Save $1,000 emergency fund
2. Pay off ALL debt except mortgage (debt snowball)
3. Build 3-6 months expenses in savings
THEN START INVESTING (Baby Step 4):
• Invest 15% of household income
• Use tax-advantaged accounts first
• Stick with good growth mutual funds
• Continue regardless of market conditions
WHY WAIT UNTIL DEBT-FREE:
• Debt interest works against you
• Average credit card rate: 20%+
• Can't out-invest high-interest debt
• Psychological freedom matters
THE MATH EXAMPLE:
• $5,000 credit card at 20% = $1,000/year in interest
• $5,000 invested at 7% = $350/year growth
• Paying debt first gives better return
EXCEPTIONS:
• Always get employer 401(k) match (it's free money)
• Don't stop during debt payoff if getting match
• Resume full 15% investing after debt-free
TIME IS CRITICAL:
• Start investing at 25: retire as millionaire
• Start at 35: need to invest 2x as much
• Start at 45: need to invest 4x as much
How much should I invest each month?
Dave Ramsey's clear recommendation: invest 15% of your gross household income for retirement.
WHY 15%:
• Balances retirement savings with current life
• Accounts for Social Security supplementing
• Allows for other financial goals (kids' college, house payoff)
• Historically builds significant wealth
CALCULATION EXAMPLE ($75,000 income):
• 15% = $11,250/year
• Monthly = $937.50
• With employer match, could be less from paycheck
HOW TO REACH 15%:
• Start where you can (even 3%)
• Increase 1% each year
• Put raises toward investing
• Add bonuses to investment
INVESTMENT PRIORITY:
1. 401(k) up to employer match
2. Roth IRA ($7,000 max in 2024)
3. Back to 401(k) to reach 15%
4. HSA if eligible
5. Taxable brokerage if above 15%
WHAT NOT TO COUNT:
• Employer match (bonus, not your 15%)
• Social Security contributions
• Pension contributions
• Real estate investments
IF YOU STARTED LATE:
• Age 40+: Consider 20-25%
• Age 50+: Catch-up contributions available
• $7,500 extra in 401(k) if 50+
• $1,000 extra in IRA if 50+
Is 7% return realistic in today's market?
The 7% return assumption is debated, but historically reasonable for long-term equity investing.
HISTORICAL EVIDENCE:
• S&P 500 (1928-2023): ~10% nominal
• Inflation-adjusted: ~7% real return
• Even including Great Depression, 2008 crash
• Long-term trend has been consistent
ARGUMENTS FOR 7%:
• 95-year track record
• U.S. economy continues growing
• Corporate profits trend upward
• Innovation drives returns
ARGUMENTS AGAINST:
• Future may differ from past
• Lower interest rates globally
• Higher valuations today
• Some predict 5-6% going forward
DAVE RAMSEY'S POSITION:
• Sticks with 7% for planning
• Uses it as real (inflation-adjusted) return
• Emphasizes long-term perspective
• Acknowledges year-to-year volatility
PRACTICAL APPROACH:
• Use 7% for optimistic planning
• Use 5-6% for conservative planning
• The key is consistent investing
• Market timing doesn't work
VOLATILITY REALITY:
• Some years: +30% or more
• Some years: -30% or more
• Average is smooth; reality is bumpy
• Must stay invested through downturns
What is the difference between Roth and Traditional retirement accounts?
The key difference is WHEN you pay taxes: now (Roth) or later (Traditional).
ROTH IRA/401(k):
• Contributions with after-tax money
• Grows tax-free
• Withdrawals in retirement: TAX-FREE
• No required minimum distributions (Roth IRA)
TRADITIONAL IRA/401(k):
• Contributions with pre-tax money
• Grows tax-deferred
• Withdrawals in retirement: TAXED as income
• Required minimum distributions at 73
DAVE RAMSEY'S PREFERENCE: ROTH
• Tax-free growth is powerful
• Tax rates may be higher in future
• More flexibility in retirement
• No RMDs forcing withdrawals
WHEN TRADITIONAL MAKES SENSE:
• Very high tax bracket now
• Expect much lower taxes in retirement
• Need the upfront tax deduction
• Employer only offers Traditional 401(k)
CONTRIBUTION LIMITS (2024):
• IRA: $7,000 ($8,000 if 50+)
• 401(k): $23,000 ($30,500 if 50+)
• Can have both types
BACKDOOR ROTH:
• For high earners over Roth income limits
• Contribute to Traditional, convert to Roth
• Pay taxes on conversion
• Legal and commonly used strategy
How do I calculate my retirement number?
Dave Ramsey's approach uses the 4% rule to calculate how much you need to retire.
THE FORMULA:
Retirement Number = Annual Expenses × 25
EXAMPLE:
• Want $60,000/year in retirement
• $60,000 × 25 = $1,500,000 needed
• 4% of $1.5M = $60,000/year income
FACTORS TO CONSIDER:
• Paid-off house reduces expenses
• Healthcare costs (major expense)
• Inflation over time
• Desired lifestyle
DAVE RAMSEY'S MODIFICATIONS:
• Pay off house before retirement
• Live on 70-80% of current income
• Social Security supplements savings
• Stay out of debt in retirement
ALTERNATIVE CALCULATIONS:
• 80% rule: Need 80% of pre-retirement income
• Expense-based: Track actual expenses
• Hybrid: Mix of approaches
REALITY CHECK:
• $1M portfolio = $40,000/year (4%)
• $2M portfolio = $80,000/year (4%)
• $3M portfolio = $120,000/year (4%)
REACHING YOUR NUMBER:
• $500/month at 7% for 40 years = $1.2M
• $1,000/month at 7% for 30 years = $1.2M
• $2,000/month at 7% for 20 years = $1.0M
What about Social Security in retirement planning?
Dave Ramsey views Social Security as a supplement, not a primary retirement plan.
DAVE'S POSITION:
• Don't count on it as your main income
• Government programs can change
• Build wealth independently
• Social Security is a bonus
SOCIAL SECURITY FACTS:
• Full retirement age: 66-67 (depending on birth year)
• Early retirement: 62 (reduced benefits)
• Delayed retirement: Up to 70 (increased benefits)
• Maximum benefit (2024): ~$4,873/month
HOW IT'S CALCULATED:
• Based on 35 highest-earning years
• Higher earnings = higher benefits
• Adjusted for inflation
• Spousal benefits available
CURRENT CONCERNS:
• Trust fund projected to deplete by 2033
• Would result in ~23% benefit reduction
• Congress will likely address (politically difficult)
• Benefits probably not disappearing entirely
PLANNING STRATEGY:
• Calculate retirement number WITHOUT SS
• Add Social Security as bonus income
• Provides cushion for unexpected expenses
• Allows for more generous retirement
WHEN TO CLAIM:
• 62: Reduced benefits (permanently)
• 67: Full benefits
• 70: Maximum benefits (8%/year increase)
• Break-even typically around age 80
DAVE'S ADVICE:
• Don't factor it into your investment calculation
• Build wealth through investing 15%
• Live below your means
• Retire with paid-off home
How does inflation affect my retirement savings?
Inflation is the "silent wealth killer" that Dave Ramsey accounts for in his 7% return assumption.
WHAT IS INFLATION:
• Rising prices over time
• Decreasing purchasing power
• $1 today ≠ $1 in 30 years
• Historical average: ~3%/year
INFLATION'S IMPACT:
• $1,000,000 in 30 years
• At 3% inflation: worth ~$412,000 in today's dollars
• Need more money to maintain lifestyle
• Retirement expenses keep rising
HOW DAVE RAMSEY ACCOUNTS FOR IT:
• Uses 7% "real" return (after inflation)
• Historical nominal return: ~10%
• Minus ~3% inflation = ~7% real
• Your projections are in TODAY's dollars
INFLATION EXAMPLES:
Item 1990 2024 Increase
Coffee $0.50 $2.50 400%
Movie ticket $4.00 $15.00 275%
Gas (gallon) $1.15 $3.50 204%
House $80K $400K 400%
PROTECTING AGAINST INFLATION:
• Invest in stocks (outpace inflation)
• Avoid keeping too much in savings
• Real estate typically keeps pace
• Bonds lag behind inflation
RETIREMENT INFLATION RISK:
• 25-year retirement = significant erosion
• Healthcare costs rise faster than general inflation
• Social Security has COLA adjustments
• Must plan for increasing expenses
What if I can't afford to invest 15% right now?
Dave Ramsey's advice: Start where you are and increase over time.
GETTING STARTED:
• Any amount is better than nothing
• Compound interest needs TIME
• Start with 3%, 5%, or whatever you can
• Increase by 1% each year
PRACTICAL STRATEGIES:
1. Get employer match (it's free money!)
2. Automate contributions
3. Budget to find extra money
4. Use raises for investing
FINDING MONEY TO INVEST:
• Cancel unused subscriptions
• Reduce dining out
• Lower phone/internet bills
• Drive older cars longer
• Shop sales and use coupons
DAVE'S BABY STEPS CONTEXT:
• Baby Step 4 is invest 15%
• But only AFTER Steps 1-3
• Pay off debt first (except mortgage)
• Build 3-6 month emergency fund
INCREMENTAL APPROACH:
Year 1: 3% + employer match
Year 2: 5% + employer match
Year 3: 8% + employer match
Year 4: 12% + employer match
Year 5: 15% + employer match
EMPLOYER MATCH IS KEY:
• If employer matches 3%, that's 6% total
• Free money you can't afford to skip
• Immediate 100% return on matched portion
• Never leave match on the table
