Figure 1
The Menu Map for the P/YR Menu
In Canada, interest rates for mortgages are, by law, given as a nominal interest rate,
compounded twice yearly. This means that the compounding period for the per-period interest
rate calculation differs from the compounding period when payments are made.
By default, the calculator performs calculations assuming that the number of compounding
periods always equals the number of payments per year. You can, however, enable the
TVM
Canada
option in the Mode menu, which enables you to select the number of compounding
periods per year. For more information, refer to Chapter 1,
Basic Features
.
To open the
P/YR
menu, press
:[
. Note the following change in features with
TVM
Canada
enabled:
1.
The P/YR key opens a menu with two items:
P/YR
and
C/YR
in which you can specify
the number of payments and compounding periods per year. See Figure 1.
2.
In the Interest Conversion menu, the
C/YR
item is the same value as the
C/YR
item in the
P/YR
menu, and it no longer affects
P/YR
. However, note how if you now change the
value of
P/YR
, the calculator automatically sets
C/YR
so it equals your new value
assigned to
P/YR
. This means that if you modify
P/YR
, you also need to modify
C/YR
, if
P/YR
and
C/YR
are different values in your TVM problem.
