The Ins and Outs of Floating Interest Rate Loans

Floating interest rate loans can be a great option for certain borrowers, but they also come with some risks. This comprehensive guide will explain everything you need to know about floating rate loans so you can decide if one is right for you

What is a Floating Interest Rate Loan?

A floating interest rate loan is a loan with an interest rate that fluctuates over time. The interest rate is tied to an index rate and moves up and down with the market.

For example, the interest rate could be tied to the prime rate. If the prime rate goes up, the interest rate on the floating rate loan goes up. If the prime rate goes down, the interest rate on the loan goes down.

This is in contrast to a fixed rate loan where the interest rate stays the same over the full term of the loan.

Floating rate loans are also sometimes called adjustable rate loans or variable rate loans. The most common types are adjustable rate mortgages (ARMs) and credit cards.

How Do Floating Interest Rate Loans Work?

Floating rate loans have two key components – the index they track and the margin

The index is a benchmark interest rate that the lender uses as a reference Common indexes include

Prime rate
London Interbank Offered Rate (LIBOR)
Treasury securities indexes

The margin is an extra percentage the lender adds to the index. For example, if the index is 5% and the margin is 2%, the actual interest rate on the loan would be 7%.

With a floating rate loan, the interest rate adjusts periodically, usually once per year. The adjustment is based on the current level of the index plus the margin.

Most ARMs have an initial fixed-rate period where the interest rate stays constant, typically 5, 7 or 10 years. After the fixed-rate period, the interest rate can change annually based on index + margin.

This means your payment amounts will vary over the life of the loan as the interest rate changes.

Pros and Cons of Floating Rate Loans

Floating rate loans offer some advantages but also come with risks to consider.

Pros:

Lower initial interest rate. The initial rate on a floating rate loan is typically lower than on a fixed rate loan. This results in lower monthly payments, at least at first.
Potential to benefit if rates fall. If interest rates decrease, your loan rate can drop and your payments will go down.
Variable rates may better match income. If your income fluctuates, a floating rate loan with fluctuating payments may align better than a fixed payment.

Cons:

Unpredictable payments. Since the interest rate changes, your monthly payment amounts will vary making it harder to budget.
Risk of payment shock. If interest rates rise significantly, your payment could increase drastically to an unaffordable level.
Difficulty refinancing. If your home value declines, you may not be able to refinance the loan before rates increase.
Less payment stability. Fixed payments help ensure housing remains affordable month-to-month.

As you can see, floating rate loans involve a trade-off between lower initial rates and payment unpredictability over the long run.

When Do Floating Rate Loans Make Sense?

Given the pros and cons, here are a few situations where a floating rate loan may be a good fit:

You plan to move or refinance before the initial fixed-rate period ends. You can take advantage of lower initial rates knowing your rate will reset later after you are gone.
You expect your income to rise substantially. Higher future income will help you handle potentially larger loan payments down the road.
Interest rates are low and likely to rise. You can lock in a low rate now and hopefully refinance later if rates increase.
You get a loan with a long fixed-rate period. A 10-year fixed intro period on an ARM provides lots of stability before any changes.

For many borrowers, however, a fixed rate loan provides greater certainty and stability over the full term.

Types of Floating Rate Loans

The most common types of floating rate loans are adjustable rate mortgages (ARMs) and credit cards.

Adjustable Rate Mortgages

ARMs come in a variety of forms with different rules regarding rate adjustments:

5/1 ARMs: 5 years fixed, then adjusts every year
7/1 ARMs: 7 years fixed, then adjusts every year
10/1 ARMs: 10 years fixed, then adjusts every year

Other key ARM features include:

Index – Usually prime rate or Treasury securities
Margin – Typically 2-3%
Rate caps – Limits maximum interest rate changes per adjustment and over life of loan
Negative amortization – Whether payment can be less than interest in early years

ARMs can be a good option for borrowers who plan to move before the fixed period ends. But payment uncertainty after the fixed period makes them riskier for long-term owners.

Credit Cards

Most credit cards have variable interest rates tied to the prime rate. When the prime rate changes, credit card rates follow.

Credit card rates are equal to the prime rate + margin determined by the card issuer based on your creditworthiness. Margins often range from 12-25%.

The variable rates on credit cards make interest costs unpredictable. Rates can fluctuate significantly so it’s important to pay balances in full each month.

Floating Rate Loan Risks

While floating rate loans offer some benefits, they also come with two major risks to understand:

Payment Shock – If interest rates increase substantially, your monthly payment could potentially double or more. Sudden large payment increases could make paying unaffordable.

For example, if you have a $200,000 mortgage at 4% interest, the monthly payment is around $955. If the rate rises to 8%, the monthly payment jumps to $1,468 – a $500+ increase.

Difficulty Refinancing – Most borrowers plan to refinance their ARM before the rate adjusts upward. But if home prices decline, you may not have enough equity to qualify for refinancing.

This could leave you stuck in the ARM with rising rates and no way to get a new fixed rate loan.

Tips for Managing Floating Rate Loan Risks

If you do opt for a floating rate loan, here are some tips to help minimize the risks:

Choose a longer initial fixed-rate period such as 7 or 10 years to delay variability.
Get a loan with smaller adjustments per year and over the life of the loan to limit payment spikes.
Factor potential payment increases into your budget to ensure you could still afford a much higher monthly amount if needed.
Try to pay down principal during the fixed period so you build equity and decrease payment sensitivity to interest rate hikes.
Know your refinance breakeven point and monitor home values so you can refinance in time.
Pay off credit card balances in full each month so you avoid accumulating costly credit card interest.

The Bottom Line

Floating interest rate loans can provide lower initial interest rates but also expose borrowers to risks related to unpredictable payments and difficulty refinancing.

For many people, the stability of fixed loan payments outweighs the lower upfront rates of ARMs or credit cards. But floating rate loans can make sense for some borrowers planning to move or refinance within a few years.

When considering a floating rate loan, be sure to factor in potential risks and have a backup plan if rates increase down the road. With proper understanding and planning, floating rate loans can be used successfully as part of an overall financial strategy.

Advantages of Floating Interest Rate

The following are the benefits of a variable interest rate:

Generally, floating interest rates are lower compared to the fixed ones, hence, helping in reducing the overall cost of borrowing for the debtor.
There is always a chance of unexpected gains. With higher risk also comes the prospect of future gains. The borrower will enjoy a benefit if interest rates decline, because the floating rate on his loan will go down. The lender will enjoy additional profit if interest rates rise, because he can then raise the floating rate charged to the borrower.

The following are the potential disadvantages of a variable interest rate loan:

The interest rate depends largely on market situations which can prove to be dynamic and unpredictable. Hence, the interest rate may increase to a point that the loan may become difficult to repay.
The unpredictability of interest rate changes makes budgeting more difficult for the borrower. It also makes it harder for the lender to accurately forecast future cash flows.
In times of unfavorable market conditions, financial institutions try to play it safe by putting the burden on customers. They will charge high premiums over the benchmark rate, ultimately affecting the pockets of borrowers.

Interest rates are some of the most influential components in the economy. They help in shaping day-to-day decisions of individuals and corporations, such as determining whether it’s a good time to buy a house, take out a loan, or put money in savings. The level of interest rates is inversely proportional to the level of borrowing, which, in turn, affects economic expansion. Interest rates influence stock prices, bond markets, and derivatives trading.

Uses of Floating Interest Rate

There are many uses for a variable interest rate. Some of the most common examples are:

Floating interest rates are used most commonly in mortgage loans. A reference rate or index is followed, with the floating rate calculated as, for example, “the prime rate plus 1%”.
Credit card companies may also offer floating interest rates. Again, the floating interest rate charged by the bank is usually the prime rate plus a certain spread.
Floating rate loans are common in the banking industry for large corporate customers. The total rate paid by the customer is decided by adding (or, in rare cases, subtracting) a spread or margin to a specified base rate.

Changes in the floating interest rate are based on a reference rate. Two of the most common reference rates used with floating interest loans are the prime rate in the U.S. and, in Europe, the London Interbank Offered Rate (LIBOR). The floating rate will be equal to the base rate plus a spread or margin.

For example, interest on a debt may be priced at the six-month LIBOR + 2%. This simply means that, at the end of every six months, the rate for the following period will be decided on the basis of the LIBOR at that point, plus the 2% spread. Floating interest rates may be adjusted quarterly, semi-annually, or annually.
