Basic examples for the TVM solver
Calculating basic loan interest
A $56,000 mortgage loan (compounded monthly) requires
monthly payments of $440 during its 20-year amortization pe-
riod. Calculate the annual interest rate on the mortgage.
N = 12 × 20 years = 240
......
PV = $56,000
I/Y = ?%
FV = 0
PMT = –$440
Default values for the number of payments per year (P/Y) and
the number of compounding periods per year (C/Y) are both set
to 1. Set these values before entering TVM variable values.
