150 Section 14: Leasing
Example 2: Using the preceding program, solve for the monthly payment using
the information given in example 1. Then change the yearly interest to 15% and
solve for the new payment amount.
Example 3: Using the information from example 1, what monthly payment is
necessary to yield the lessor 15% annually if one payment is due at the time of
closing?
Assuming that the previous example was just solved, the keystrokes are as
follows:
Since this problem is an annuity due situation (one payment at the beginning of
the period) the calculation could also be done as follows:
Solving for Yield
To calculate the periodic yield, information is entered as follows:
