Retirement Planning Tips That Work
- Start early — a 25-year-old saving $500/month at 7% retires with ~$1.2M at 65. Starting at 35 yields only ~$567K. Time is your biggest advantage in retirement planning.
- Maximize employer match — if your employer matches 50% up to 6% of salary, contribute at least 6%. That's an instant 50% return on your money before any investment gains.
- Use the 4% rule as a guideline — withdrawing 4% of your nest egg annually has historically been sustainable for 30-year retirements. Adjust based on your risk tolerance and life expectancy.
- Account for inflation — $4,000/month today will feel like ~$2,000 in 30 years at 2.5% inflation. Always look at the inflation-adjusted projections when planning for retirement.
- Diversify across account types — combine tax-deferred (401k, Traditional IRA), tax-free (Roth IRA), and taxable brokerage accounts for tax-efficient withdrawals in retirement.
