One of the key questions that always surrounds any reverse mortgage is how much money you, as the borrower, will be able to draw from the loan. The amount of money you can get from the proceeds of a reverse mortgage is primarily based on two important factors: your age, and the loan’s interest rate.

Typically, older a borrower is, the more money he or she can receive in proceeds. By that same token, when the interest rate is lower, generally there is more money available to borrow. The higher that the loan’s margin is, the lower the interest rate will need to be in order to increase the maximum amount of money a borrower can receive from a reverse mortgage.

The actual note rate on a Home Equity Conversion Mortgage (HECM) loan that you’ll want to keep an eye on is called the initial interest rate (IIR), which is the actual interest rate charged at the beginning of the loan and calculated by adding the index and the margin together.

So, in this article, we’re going to be going over a few of the different factors that surround the reverse mortgage margin, and what these elements all mean for you.

1. What is the index?
2. What’s the margin?
3. What’s LIBOR?
4. How do these things affect me?

You might naturally be asking yourself exactly what are the index and the margin, two individual elements that will dictate your reverse mortgage initial interest rate (IIR). So, to start with, here are the two elements that combine to make up that very important part of your loan.

## What’s the index?

The index is a base interest rate that serves as a kind of foundation for the initial interest rate (IIR) of your reverse mortgage. It also acts as a kind of tide that determines the floor for the IIR, meaning that if the index goes up, then so will the IIR.

## What’s the margin?

The margin is the interest percentage that is added on top of the index by the lender, which provides the full IIR for your reverse mortgage. The margin is not adjustable, which means that after your loan is originated, the margin will stay the same for the duration of the loan regardless of any changes to the index.

There is no index or margin for a fixed-rate HECM loan because the IIR is set for the life of the loan, so these elements apply only to the more popular variable-rate HECM loan.

## What is LIBOR?

The indices used for the variable-rate HECM is often the 1-month LIBOR and the 1-year LIBOR. LIBOR stands for London Interbank Offered Rate and is the rate of interest that banks use when lending money to each other in London, England’s wholesale money markets. In the United States, the LIBOR is used as a standard financial index in capital markets and is usually published in the Wall Street Journal.

## How do these things affect me?

You’ll definitely want to pay very close attention to the rates provided by the reverse mortgage lenders as you’re shopping around. These rates play an extremely important part in determining how much money you could receive from the proceeds of your reverse mortgage loan and even how much equity will remain in your home at the end of the loan’s life before it is repaid.

The total amount of the interest rate can also be affected by factors such as the amount remaining on your forward mortgage (if you have one), a financial assessment which determines your ability to keep up with insurance and maintenance costs and the appraised value of your home.

Basically, at the end of the day, you will be able to receive more money for your home when both the margin and index is low, which translates to a low IIR.
