What is a loan constant? - YouTube

The loan constant, also known as the mortgage constant, is a percentage that displays the

annual debt payment on a loan as a proportion of the entire principal value.

Borrowers could compare the loan constants of several loans before coming to a decision.

The borrower picks the loan with the lowest 

loan constant to reduce the  debt service requirements,

meaning the borrower will pay less in principal and interest over time.

Frequently Asked Questions (FAQs)

How does a loan constant function?

The annual debt payments on a loan are compared to the entire principal value of the loan.

Thus, the debt payment on a loan is the total amount of money the borrower will have to

pay to cover the repayment of the loan's principal and interest over a set period.

In the business and financial worlds, the term "principal" has several connotations.

The initial size of a loan or a bond is referred to as principal in the context of borrowing.

For instance, if you borrow AU$80,000, the principal will be AU$80,000.

If you pay down AU$50,000, the remaining AU$30,000 is the principal balance.

Furthermore, the amount of interest you will pay on a loan is determined by the principal.

For example, if your loan has a principal of AU$30,000 and a 10% annual interest rate,

you will be obliged to pay AU$3,000 in interest for each year the loan is due.

The loan constant is a percentage that may be determined for any loan.

It enables analysts and borrowers to understand better the factors that influence a loan and

how much they are paying annually compared to the loan principal.

How to calculate a loan constant?

Calculating the loan constant  frequently necessitates 

a borrower obtaining the various terms linked

with the loan agreement.

The loan interest rate, total principal, frequency of payments, and length of payment are all

included in the terms.

Obtaining these loan term components enables the monthly payments to be calculated using

a simple present-value payment method.

Once the monthly payments have been set, the loan constant can be calculated using the

following equation:

A mortgage borrower, for example, took out an AU$100,000 loan.

The loan has a fixed interest rate of 7% and a period of 25 years.

Using a payments calculator, the borrower would pay approximately AU$84,000 in annual

debt service.

Therefore, the loan constant for the borrower would be AU$84,000 / $100,000, or 8.4%.

The periodic annual payments are calculated by multiplying the loan constant by the original

loan principal.

To compare the actual cost of borrowing, the loan constant can be employed.

Loan constants are only applicable for fixed interest rates since variable interest rates

have various annual debt service amounts dependent on variable interest.

Therefore, if borrowers choose between two loans, they will typically choose the lower

loan constant since it will require minor debt servicing.

Before the invention of financial calculators, loan constant tables were frequently utilised

in the real estate business because they made calculating monthly mortgage payments very

simple.

Borrowers can use loan constant tables to get pre-populated information about their

loan with a quoted loan constant level.
