You can see that the EL-733A is a handy tool to take with you whenever you are on the way to buy a car or to make some purchase that will involve financing. But we haven't yet covered all the aspects of TVM problems. We have only covered PMT and PV calculations to this point, and this is just a scratch on the surface of financial calculations. ALLOON PAYME TS AND ALCUL>ATIONS On the EL-733A, the future value ( Q ) is an amount left at the end of the cash-flow schedule that is separate from any regular payment that may occur at that same point. In the case of a balloon payment, which is a payment at the end of a loan contract that completely pays of the remaining balance, it is important to recognize that the result for FV may have to be added to a payment amount to determine the actual final payment amount on the loan. Example: As a construction engineer, you recently got a five year contract job in Utah overseeing the construction of a modern, clean, coal-fired power plant. You were able to purchase a nice house with a 15 year mortgage of $97'000.00 at an interest rate of 11.5% APR. However because your job is on a five year contract, a balloon payment is scheduled at the end of those five

ALLOON
PAYME
TS
AND
ALCUL>ATIONS
On
the
EL
-733A,
the
future
value
(
Q
)
is
an
amount
left
at
the
end
of
the
cash
-flow
schedule
that
is
separate
from
any
regular
payment
that
may
occur
at
that
same
point.
In
the
case
of
a
balloon
payment,
which
is
a
payment
at
the
end
of
a
loan
contract
that
completely
pays
of
the
remaining
balance,
it
is
important
to
recognize
that
the
result
for
FV
may
have
to
be
added
to
a
payment
amount
to
determine
the
actual
fi
nal
payment
amount
on
the
loan.
Example:
As
a
construction
engineer,
you
recently
got
a
fi
ve
year
contract
job
in
Utah
overseeing
the
construction
of
a
modern,
clean,
coal-fired
power
plant.
You
were
able
to
purchase
a
nice
house
with
a
15
year
mortgage
of
$97'000.00
at
an
interest
rate
of
11.5%
APR.
However
because
your

a
