Quick Tips
- •Always contribute enough to get the full employer match—it is free money and a guaranteed return on investment.
- •Increase your contribution percentage when you receive raises to maintain your savings lifestyle without reducing take-home pay.
- •At age 50, you become eligible for catch-up contributions ($7,500 additional in 2024). This is crucial for catching up if you started saving late.
- •Review your investment allocation (stocks vs. bonds) based on your age. Younger workers can afford more stocks for growth; near retirees should shift toward bonds.
- •Do not touch your 401(k) before retirement unless absolutely necessary. Early withdrawals incur a 10% penalty plus income tax, drastically reducing your balance.

Examples
Contributing 10% of a $85,000 Salary from Age 30
You contribute 10% of your $85,000 salary ($8,500/year) starting at age 30, with a 50% employer match up to 6% ($2,550/year). Assuming 7% annual growth, your 401(k) reaches approximately $1,180,000 by age 65. Your total contributions are $297,500 and employer contributions add $89,250, with investment growth providing the rest.
Maximizing Contributions with Catch-Up at Age 50
You contribute the IRS maximum of $23,500/year from age 35 to 49, then increase to $31,000/year (with $7,500 catch-up) from age 50 to 65. With a 4% employer match on a $120,000 salary ($4,800/year) and 7% returns, your balance grows to roughly $2,050,000 by age 65.
