## Traditional vs Roth 401(k)
### Traditional 401(k) Benefits
- **Immediate tax deduction** reduces current income tax
- **Lower taxable income** may qualify you for other tax benefits
- **Tax-deferred growth** until withdrawal
- **Best if** you expect lower tax bracket in retirement
**Example**: $10,000 contribution in 25% bracket saves $2,500 in taxes today
### Roth 401(k) Benefits
- **Tax-free withdrawals** in retirement (contributions + growth)
- **No required distributions** if rolled to Roth IRA
- **Tax diversification** in retirement
- **Best if** you expect higher taxes in future or are young
**Example**: $10,000 grows to $80,000 tax-free over 30 years
### Combining Both Types
- **Hedge your bets** on future tax rates
- **Flexibility** in retirement withdrawals
- **Optimize** based on current vs expected tax bracket
- **Adjust** percentages as income changes
**Common Split**: 70% traditional / 30% Roth for tax diversification
