Step 1: Verify You Are Capturing the Full Match

Open your benefits portal today and confirm your current contribution rate. Compare it to your employer’s match formula. If you are not meeting the match threshold, increase your rate immediately — the next payroll cycle is close enough. This single step is worth more than all the investment optimization in the world for most participants.

Step 2: Audit Your Investment Funds for Fees

List every fund in your 403(b) and note the expense ratio. If you hold a variable annuity, request the full contract and find the mortality and expense charge. Anything above 0.50% total is worth reconsidering. Switch to the lowest-cost index fund available — typically an S&P 500 or total market index.

Step 3: Set Asset Allocation by Age

A common allocation rule of thumb: subtract your age from 110 to get your stock percentage. Age 35 = 75% stocks. Age 50 = 60% stocks. Adjust based on your risk tolerance and other income sources (pension, spouse’s income). If you have a generous defined-benefit pension, you can afford to be more aggressive in the 403(b) since the pension provides fixed income security.

💡Target-Date Funds: Hands-Off Optimization

If you do not want to manage allocation, a target-date fund (e.g., Vanguard Target Retirement 2045) automatically adjusts your stock/bond mix as you approach retirement. Look for target-date funds with expense ratios below 0.15%.

Step 4: Set Up Auto-Escalation

Most 403(b) platforms allow you to set automatic annual increases — 1% per year is standard. Schedule the increase to coincide with your annual raise (typically July 1 or January 1) so you do not feel the impact. Over 8 years, auto-escalation from 5% to 13% adds $162,000 additional balance on an $80K salary at 7% return.

Step 5: Update Your Beneficiary Designation

Your 403(b) beneficiary designation overrides your will. An outdated beneficiary — an ex-spouse, a deceased parent — can send your retirement savings to the wrong person. Review and update your designation annually. Name both a primary and a contingent (backup) beneficiary.

Step 6: Decide Traditional vs Roth for New Contributions

If your plan offers both traditional and Roth, make an active choice — do not default. Review your current bracket (22% in 2025 for $47,150–$100,525 taxable income single filer) versus expected retirement bracket. If you are below 22%, Roth is typically superior. At 24%+, traditional generally wins.

Step 7: Consolidate Old 403(b) Accounts

If you have 403(b) or 401(k) balances from previous employers sitting in old accounts, roll them into your current 403(b) or a low-cost IRA. Forgotten accounts accumulate fees, may have poor fund options, and complicate retirement planning. Consolidation simplifies management and often unlocks better investment choices.

Step 8: Run Annual Calculator Projections

Once a year — ideally during open enrollment — run a fresh 403(b) projection using updated salary, balance, and contribution rate. Compare your projected balance against your retirement income target. If there is a gap, adjust the contribution rate now rather than discovering the shortfall at 62. The annual review turns a passive savings account into an active retirement plan.
