Creating an Amortization Schedule
You borrow 140,000.00 for 360 months at 10% interest. Create an amortization schedule for
the loan. How much interest did you pay for the first year? What is the balance of your loan
after the first year? See Table 3-4. The example below is calculated with Chain set as the
operating mode, but it can be performed in RPN, Chain, or Algebraic.
