The two most common types of Lines of Credit (LOC) would be a personal LOC (PLOC) and a Home Equity
LOC (HELOC).
All lines of credit follow these rules:
2. They have a set borrowing limit ("credit limit").
3. They require a minimum monthly payment (usually 2% to 3% on a personal LOC and 1% to 2% on a HELOC).
4. Unlike an installment loan, you are unable to pay the loan in advance.
5. You only have to pay interest on the outstanding (borrowed) balance.
A LOC is a loan that you can receive that will, in essense, assure a certain amount of funds are available
whenever you need it. Furthermore, you only pay interest on the money you have borrowed.
For example, say you are approved for a $5,000 line of credit at 10% interest. Assuming there are no
annual fees, you can have this LOC for 5 years and never pay one cent in interest if you never borrow any funds.
Let's say after 5 years you need to borrow $1,000 from the LOC.
For the sake of argument, let's say that you borrow the $1,000 on January 1. Now if you turn around
and pay all $1,000 off (for whatever reason) the very next day, you will only owe one day's worth of interest. The daily
interest (or "per diem") would be approximately 27 cents ([$1,000 X .10] / 365). So on January 2nd, the payoff balance
would be $1,000.27. Each day that passes after January 2nd, another 27 cents is owed onto the account. The only
exception would be when/if payments are received on a regular basis (rather than a complete payoff). Payments would
decrease the per diem according to the remaining loan balance.
So, continuing the example, you will notice that on January 3rd, the payoff would be $1,000.55 (because of
rounding upwards); $1,000.82 on January 4th, etc.
Going back to the beginning of the example, let's say that you borrow $1,000 on January 1 and intend to pay
it off in 6 months. Now, the institution you borrowed the $1,000 from will require a minimum monthly payment (usually
2 to 3%). Let's use 3% for our example. And, for the sake of simplicity, let's assume that the statement ending
date on the LOC is the last day of each month and that the due date for the minimum payment is due the last day of the
following month. This means that on January 31st our statement will cut and we will receive in the mail a few days later
our loan statement and due date. The statement will then inform us that the minimum payment of $30 ($1,000 X .03)
is due February 28th. Unlike a credit card, however, this is not "free money" (due to the grace period on credit
cards) until February 28th: you will be paying interest on it the whole time. As I mentioned before: if you borrow the
money on Jan 1 and pay it off on Jan 2, you will still owe 27 cents in interest. If this were purchases made on a credit
card, you'd have a grace period (usually 25 days) where you could pay it off and still not owe interest. So in this
case, you could charge on the credit card and not have any interest due as long as you pay the balance off in full by the
due date.
So, let's say you send in your payment on February 15th (cause you always want it to be early rather than
late, right?) and the institution receives and posts the payment to your account on February 19th. This would mean that
50 days would have passed since the day you borrowed the money and the day you made your minimum payment.
If you remember, our per diem (how much it costs you to per day to borrow these funds) is approximately 27
cents. So, when you send in your minimum payment of $30, the first $13.70 ([$1,000 X .1] / 365 X 50) goes directly to
the financial institution as an interest payment. This means, instead of owing $970 on February 19th, you still would
owe $983.70. Our per diem is still actually at 27 cents (due to rounding) but as you make more and more payments your
per diem will approach 0.
