Most 401(k) Mistakes Start Small
Retirement plans usually fail through small repeated errors, not one event. Infrequent reviews, low contribution rates, and missed match are common drags.
People usually do not blow up a retirement plan with one dramatic move. More often, they miss the match, leave the rate unchanged for years, or assume future raises will fix everything on their own.
Audit the Friction Points
Start with your current salary, balance, contribution rate, employer match, and expected retirement age. Then compare at least two versions of the same plan instead of trusting a single projection.
Look for the decisions you have been postponing: increasing contributions, cleaning up fund overlap, naming beneficiaries, or checking vesting and fees. The goal is to remove avoidable drag, not to build a perfect spreadsheet.
Use the calculator to pressure-test the choice, then confirm any plan-specific details in your employer documents when those details affect the outcome.
