Compounding Periods Different From
Payment Periods
In financial calculations involving a series of payments equally spaced in time with
periodic compounding, both periods of time are normally equal and coincident. This
assumption is preprogrammed into the HP 12C Platinum.
In savings plans however, money may become available for deposit or investment at a
frequency different from the compounding frequencies offered. The HP 12C Platinum can
easily be used in these calculations. However, because of the assumptions mentioned the
periodic interest rate must be adjusted to correspond to an equivalent rate for the payment
period.
Payments deposited for a partial compounding period will accrue simple interest for the
remainder of the compounding period. This is often the case, but may not be true for all
institutions.
These procedures present solutions for future value, payment amount, and number of
payments. In addition, it should be noted that only annuity due (payments at the beginning
of payment period) calculations are shown since this is the most common in savings plan
calculations.
