Calculator guide
Understanding 401(k) Vesting Calculator
Vesting separates the employer-funded balance shown in an account from the portion currently owned under the plan's service schedule.
Calculation method
How the calculation works
Compound the current employer-funded balance through the entered milestone years, add future employer contributions, and apply current and next scheduled vesting percentages. Split the current employer balance, compound it at the entered annual return for the years to the milestone, add future employer contributions, and apply the next vesting percentage.

Worked situations
Practical examples

Better inputs
Useful tips
- Request the summary plan description.
- Confirm treatment of breaks in service.
- Separate each contribution source when schedules differ.
Before relying on the result
Limitations and common mistakes
- Service rules, forfeitures, acquisitions, termination events, and source-specific schedules are excluded.
- The annual investment return is a constant scenario, and future contributions are added without modeling their individual deposit dates.
- The official plan record controls.
