This is a genuinely difficult question because "enough" depends on many personal factors:

**Key variables:**
- Your current age and target retirement age
- Annual spending needs
- Life expectancy assumptions
- Healthcare costs
- Geographic location
- Investment returns (historically ~7-10% stocks, 3-4% bonds)
- Inflation (2-3% average)

**Common rules of thumb:**
- **25x rule**: Save 25 times your annual spending (assumes 4% withdrawal rate)
- **30x rule**: More conservative; accounts for longer lives/market volatility
- Example: If you spend $40k/year, you'd need $1-1.2M

**Realistic factors:**
- Social Security/pensions reduce needed savings
- Healthcare before Medicare (age 65) is expensive
- Most people underestimate spending in early retirement
- Market downturns can force delayed retirement
- Inflation compounds over 30+ year retirements

**Honest truth:** Most financial advisors recommend calculating your actual annual expenses, multiplying by 25-30, then adding a 20-30% buffer for uncertainty. If that number feels impossible, consider working longer, spending less, or generating supplemental income in retirement.

What's your rough timeline and annual spending? That would help estimate a more specific number.
