How This 401k Calculator Works

Enter your salary, contribution rate, employer match, current balance, age, and expected returns. The calculator compounds your contributions annually, accounting for salary growth each year, and shows your projected balance at retirement age.

What Is an Employer Match?

Many employers match your 401k contributions up to a certain percentage of your salary. For example, a "3% match" means your employer adds an extra 3% of your salary to your 401k when you contribute at least 3%. This is essentially free money and you should always contribute enough to get the full match.

The 4% Withdrawal Rule

A common retirement planning guideline suggests you can safely withdraw 4% of your portfolio per year in retirement without running out of money. This calculator uses that rule to estimate your monthly retirement income from your 401k balance.
