Calculator limitations

The calculator will not:

- Verify your eligibility for a benefit.

- Determine your future salary.  (It is up to you to estimate what the average of your highest five consecutive years of salary will be at retirement.  If the actual final average salary is different than the one you entered, your benefit estimate will be different than the actual benefit.)

- Determine your projected service credit at retirement. (You must project the number of years of service credit that you will have at retirement. If the service credit that you enter is incorrect, your estimate will not be the same as your actual benefit.) 

Calculator Disclaimer

If the results of your estimate differ from your official benefit calculation at retirement, the official calculation based on the ERA, will be used.  The accuracy of your estimate depends on how closely the variables you enter on the input screens match those at retirement.  The calculator provides unofficial estimates only. 

I have read and understand this disclaimer and I agree that any estimates provided by the calculator will be done so under these conditions.
