Retirement Planning Checklist: What to Do at Every Age

Your 20s are the most powerful decade for retirement savings because of compound interest. A $5,000 annual contribution starting at age 25 grows to roughly $1.1 million by age 65 at a 7% average return. The same contribution starting at 35 reaches only $540,000. The single most important step is enrolling in your employer's 401(k) and contributing at least enough to capture the full employer match — this is an immediate 50-100% return on your money. If your employer offers a Roth 401(k) option, consider it seriously: paying taxes now while you're in a lower bracket means tax-free withdrawals in retirement. Open a Roth IRA as a complement; the 2026 contribution limit is $7,000 for those under 50. Choose a low-cost target-date fund or a simple three-fund portfolio (US stocks, international stocks, bonds) and automate your contributions. Avoid the temptation to keep retirement funds in a money market or stable value fund — at this age, you have decades to recover from market downturns, and the opportunity cost of not being invested in equities is enormous.

Your 30s and 40s are the accumulation powerhouse years. By age 30, aim to have 1x your annual salary saved for retirement. By 40, the target is 3x your salary. These benchmarks come from Fidelity's widely cited retirement guidelines. In your 30s, push toward maxing out your 401(k) ($23,500 in 2026) and IRA ($7,000). If you receive raises, direct at least half of each increase toward retirement savings before lifestyle inflation absorbs it. Review your asset allocation annually — a common guideline is to hold your age in bonds (30% bonds at age 30), though many advisors now suggest a more aggressive 80-90% stock allocation through your 40s given longer life expectancies. Your 40s bring competing priorities: college savings for children, potential caregiving for parents, and peak housing costs. Resist the urge to reduce retirement contributions to fund these expenses. College can be financed with loans, scholarships, and work-study; retirement cannot be borrowed. Consider a backdoor Roth IRA conversion if your income exceeds direct Roth contribution limits. This is also the time to purchase adequate disability insurance and update your estate plan — a will, beneficiary designations, and powers of attorney.

Your 50s are the final stretch of serious accumulation and the time to get highly specific about your retirement plan. Starting at age 50, you can make catch-up contributions: an additional $7,500 to your 401(k) (total $31,000 in 2026) and $1,000 extra to your IRA (total $8,000). These catch-up provisions can add over $100,000 to your retirement savings in the decade before retirement. Run a detailed retirement projection using your actual account balances, expected Social Security benefits (check ssa.gov), any pension income, and realistic expense estimates. Stress-test your plan against scenarios like a 40% market decline in year one of retirement, higher-than-expected healthcare costs, and living to age 95. Begin gradually shifting your portfolio toward a more conservative allocation — moving from 80% stocks to 60-65% stocks over the decade. However, don't become too conservative: you still need growth to sustain a 25-30 year retirement. Pay off your mortgage if possible before retirement to reduce fixed expenses. Consider long-term care insurance while you're still insurable — premiums increase dramatically with age and health conditions.

Your 60s require tactical precision. The single biggest financial decision is when to claim Social Security. Benefits increase approximately 8% for each year you delay past your full retirement age (67 for most people) up to age 70. For a $2,000 monthly benefit at 67, waiting until 70 increases it to $2,480 — a 24% permanent raise. If you're healthy and have other income sources, delaying is usually optimal. Enroll in Medicare during the initial enrollment period around your 65th birthday to avoid permanent premium penalties. If you have an HSA, stop contributing 6 months before Medicare enrollment (Medicare is retroactive 6 months). Create a tax-efficient withdrawal strategy: draw from taxable accounts first, then tax-deferred (Traditional IRA/401(k)), and let Roth accounts grow last. However, strategic Roth conversions in low-income years between retirement and age 73 can reduce future required minimum distributions. Build a cash reserve of 1-2 years of expenses so you never have to sell investments during a market downturn. Finally, update all beneficiary designations, create or update your estate plan, and consider establishing a durable power of attorney and healthcare directive.
