414h calculation

[Guest pthomann]

Does anyone know how to determine an estimate of the "required amount" to be contributed for a defined benefit plan (414h)?

For example:

Assume an individual is 42 years old and is eligible for a 20 year service retiree pension of 50% of final average salary. The employees final avg. salary is $80,000. Also the employee has contributed 5% of his yearly salary for only 15 years out of the 20 year period.

Is there a way to determine what the employees "required amount" in his pension account should be in order not to reduce his pension below 50%?

In addition, are there any good books and/or tables to help in calculating this?

Any insight would be helpful.

Thank-you.
