About 401(k) Calculator
VestCalc's 401(k) Calculator is a free online retirement planning tool designed to help individuals at every career stage model their financial future with clarity and confidence. Whether you are just starting to save for retirement or approaching your target retirement date, this calculator lets you visualise how your current contributions, employer matching, investment returns, and time horizon combine to build long-term wealth.
Retirement planning is one of the most important financial decisions you will make yet most people underestimate how early they need to start and how dramatically small changes in contribution rate or return assumptions affect their final balance. Our 401(k) Calculator makes these relationships visible with instant recalculation as you adjust inputs, empowering you to test different strategies and understand their real-world impact.
Key variables modelled include current savings balance, annual contributions, employer match percentage, expected annual return, inflation adjustments, and years until retirement. The tool calculates projected balances, total contributions versus investment growth, and monthly income projections in retirement giving you a complete picture of your financial trajectory.
VestCalc is committed to making professional-grade financial planning tools accessible to everyone. This 401(k) Calculator is completely free, requires no account, and stores none of your data. Use it as often as you like to model different scenarios adjusting your savings rate, retirement age, or return assumptions and make informed decisions about your financial future.
