Borrow

Version: 2
Summary: Mortgage and Loan APR Calculator
License: Freeware

Email: finnegam@eircom.net
Download: borrow2.zip (Dec 24 2000, 74.6K)
Description:
Borrow is a DOS APR calculator program that includes the
full source code written in C++. It can tell you how many months it
will take to repay a loan; the nominal rate%, the effective rate%; the
amount you can borrow, if you supply it with figures for the number of
installments spread over the loan's life, the interest rate (either the
nominal or the effective rate) and amount of each regular fixed
payment; amount of the periodic payment if you supply figures for the
number of installments per year, and the number of times the interest
is compounded each year (usually every month), the interest rate can
be expressed as either the nominal rate or the effective rate, and the
amount you want to borrow. This is the most frequently used option.

The program automatically displays an amortization schedule for the
first 12 installments showing a breakdown of the fixed regular payment.
It shows the amount of interest on the declining, outstanding balance
of the loan at the end of each installment period, and the amount of
the loan you are repaying out of the fixed regular installment. It
also shows the outstanding loan balance. If you press the <home> key
you can toggle the display. Then it shows the total interest payable
for each year and the total principal payable for each year of the
loan's life. These figures are useful when you need to deducted the
annual mortgage interest on a loan from taxable income.

You can now enter the interest rate as either the nominal or the
effective interest rate. In America they call the nominal rate the
APR%, but in Ireland & the UK we call the APR% the effective or true
rate. For example, if you see a product, such as a computer,
advertised in an Irish or British paper at an APR of 16%, this means
the effective interest rate. Version 1 of the borrow program only
accepted the nominal rate. Instead of having to figure out the
conversion you can how enter the APR directly into the effective rate
input field and the program will automatically display the nominal
rate and the rest of the results, including the amortization schedule.

Borrow allows you the option of changing the number of compounding
periods per year. For example, it is quite common to repay loan
installments every 2 months, or quarterly. If you bought a computer
through the ESB in Ireland you would be paying every two months with
your electricity bill, and the term APR% in their advertisement would
not refer to the American definition, but the effective interest rate.
Before deciding which computer to go for you might like to consider a
number of options, such as paying over 3 years or 2 years, and you
might also like to compare ESB's figures with those of a regular TV,
Video and computer shop that charges different rates, and requires you
to make the regular installments every month.

This program allows the user to add columns of numbers or equations, solve derivatives of equations and lists of equal spaced data, solve integrals of equations and equal spaced data, solve simple equations, average or sum tables of numbers, and more. Descriptive variable names such as "moving expenses" are allowed (including the space between the words "moving" and "expenses"). The history file may be opened and closed as desired to record information as it is displayed on the screen. The software registration allows upgrades to "student" and "full" distributions (you need not be a student to order a student distribution, but some software limitations are included in the student distribution).

payments at different frequency from weekly to yearly, as well as
interest-only loans and constant-paydown amortization.

The present value screen allows for combinations of single payments at
arbitrary times and periodic payment series. Payments for life and
payments upon death are valued with tables of actuarial probability,

Description:
The RPNM series of Calculators is a group of calculator programs that
were produced by Harry Smith of Saratoga CA. These calculators are
unusual in that they not only provide very extended precision arithmetic
(numbers with several thousand digits), but they also permit the user to
define the precision for the calculator (up to the limit of your
particular system's memory). The ability to set the calculator's
precision is desirable to control the speed of the calculations.

The calculators also utilize Reverse Polish Notation (RPN), thus the
name of the series is RPNMx, for RPN Multiple precision; and x is used
to distinguish between the different individual calculators of the
series. There are currently three different calculators in the RPNMx
series:

RPNMI - Integer
RPNMF - Floating point
RPNMS - Scientific
