Footnotes

  • I am not a financial advisor; this is not financial advice.

  • Certain values computed here could be off by 1¢ (depending on how different institutions handle fractions of a cent).

  • Employee + company 401k contributions combined should not exceed $70,000. This calculator does not enforce this limit.

  • The company has now introduced a true-up feature, but eligibility is contingent on a few factors and the true-up payment will not be delivered immediately. For those reasons, some employees may still be interested in maximizing per-paycheck matching.

  • Fidelity only allows integer contribution percentages (as does this calculator).

  • Fidelity will automatically cap 401k contributions at the yearly limit, but if you contributed to a different 401k account for another job this year, you are responsible for contributing the correct amount to this account.

  • Fidelity's website doesn't update as soon as contributions are made, and the way it displays end of year contributions can be misleading. I recommend using payslips as a source of truth.
