Yes, I do have such a calculator, but their are too many variables......loan period (in years), effective interest rate, amount of diferred interest or prinicpal payments, etc.

To really know what is going on, one would have to look at the form of the borrowing, which should be available to PERS employees (one would think?)

A REAL engineer could figure it out! <R,D,&G>

I couldn't resist. How about assuming 30 years, compounded monthly. Or conversly, assume 4% interest rate compounded monthly, and solve for the number of periods.

Try annually if monthly doesn't work.
