The
Time
Value
of
Money
(TVM)
equation
computes
the
effect
of
compound
interest
on
a
debt
or
investment.
It
applies
only
when
the
payment
each
period
is
uniform;
if
the
payment
varies,
use
the
—_CFLOW
template
(see
pages

N
is
the
total
number
of
periods
during
the
loan
or
investment;
I%YR
is
the
nominal
rate
of
interest
(APR
or
ROI);
PV
is
the
present
value
of
the
investment
or
loan;
PMT
is
the
amount
of
the
periodic
payment,
FV
is
the
future
value
of
the
loan
or
investment
after
N
periods
(FV
is
generally
opposite
in
sign
to
PV);
P/YR
is
the
number
of
periodic
payments
per
year;
S
is
a
variable
that
accounts
for
the
effect
of
payments
made
at
the
beginning
of
each
period
(S
=
1),
vs.
the
end
(S
=
0).
The
TVM
menu
lets
you
input
values
for
any
of
the
above
variables,
in
order
to:
(1)
solve
the
TVM
equation
for
N,
I%YR,
PV,
PMT,
or
FV;
(ii)
construct
and
print
amortization
tables;
(iii)
compare
nominal
vs
effective
interest
rates.
