How to use 401K Calculator

Add your contribution plan and any matching formula, and the calculator will estimate how the workplace retirement account could grow over time.

What this calculator is for

This calculator is for workplace retirement planning and contribution strategy decisions. It is especially helpful when you want to see the long-run value of capturing the full employer match or increasing contributions gradually.

Tips

Make sure the contribution figure reflects how you actually save, whether by dollar amount or by a percentage of pay converted to dollars.
Employer match rules vary widely, so check the plan formula before relying on a projection that assumes a full match every year.
