Retirement Planning Guide: 401(k), IRA, and Savings Strategies

Complete retirement planning guide covering 401(k) contributions, IRA strategies, compound interest, required minimum distributions, and how to calculate if you're on track.

Planning for retirement is one of the most important financial decisions you'll ever make. Whether you're 25 or 55, the tools and strategies in this guide will help you understand how much you need to save, which accounts to use, and how to maximize tax-advantaged growth over time.

How Much Do You Need to Retire?

The widely used "4% rule" suggests you can withdraw 4% of your portfolio annually without depleting it over a 30-year retirement. Under this rule, retiring on $50,000/year requires a $1.25 million nest egg. A more personalized estimate factors in Social Security income, expected healthcare costs, and your target retirement age.

401(k) vs. IRA: Which Is Right for You?

A 401(k) offers higher contribution limits ($23,000 in 2025, $30,500 if 50+) and potential employer matching — always contribute enough to capture the full employer match first. Traditional IRAs and Roth IRAs have a $7,000 combined limit ($8,000 if 50+). Roth accounts are best when you expect to be in a higher tax bracket in retirement.

The Power of Compound Growth

Starting at 25 and investing $500/month at 7% average annual returns yields ~$1.3 million by age 65. Waiting until 35 to start the same contributions yields just ~$610,000 — showing that time is your most valuable retirement asset. Even small increases in monthly contributions early in your career compound dramatically.

Required Minimum Distributions (RMDs)

The IRS requires you to begin withdrawing from traditional 401(k) and IRA accounts at age 73 (as of the SECURE 2.0 Act). Missing an RMD triggers a 25% penalty on the amount not withdrawn. Roth IRAs have no lifetime RMDs, making them excellent for estate planning.
