How Does a 5 Year ARM Work?

A 5/1 adjustable-rate mortgage (ARM) begins with an initial fixed-rate period of five years before transitioning into its adjustable-rate phase, where your rate readjusts annually, depending on financial indices.

ARMs come equipped with caps limiting how much the interest rate can change during each adjustment period, including an initial, periodic, and lifetime rate cap to protect you from higher interest rates.

Adjustable Rate Mortgages

ARMs may provide lower initial interest rates than fixed-rate mortgages, making their payment savings attractive to buyers. But they can be riskier in the long run as payments could increase if the index rate adjusts upward, though many ARMs feature caps that restrict how much your interest rate or payment increases over six-month intervals.

Jeff Ostrowski writes about mortgages and housing for Bankrate. According to him, adjustable-rate mortgages (ARMs) may be suitable for people planning to sell or refinance before their initial fixed-rate period expires.

However, if your income fluctuates or you need to relocate for work, a 5-year adjustable-rate mortgage (ARM) could prove costly regarding interest rate and closing costs. An inquiry on your credit report could negatively affect its length and score.


ARMs, or adjustable rate mortgages (ARMs), feature an initial fixed-rate period before their rates adjust based on financial indices linked to them – these indices could rise or fall, and lenders must place caps on how high rates they can charge.

With the 5/1 adjustable-rate mortgage (ARM), the initial fixed-rate period only lasts five years before adjusting based on market rates annually. Most ARMs have caps to limit how much their rate jumps at each readjustment period.

Your adjustable rate loan disclosure booklet will outline how your rate and payment may fluctuate during its term, but when comparing loans, you should keep a few key numbers in mind when making decisions: initial rate period and adjustment interval are two such key figures; some adjust annually while others reset every six months (such as 3/1 or 7/1 ARMs) (some even adjust every three or seven months!). Lender margin, added onto index rates, may also play a crucial role.

ARM Rates

ARMs typically track two key interest rate factors: an index and margin. Lenders use this index amount to calculate their loan’s underlying interest rate, while the margin represents the percentage points added. A lender’s interest rate cap structure is vital; it controls how much your rate changes at every adjustment period or over its lifecycle.

ARMs typically feature an initial fixed-rate period that lasts three, five, or ten years before entering their adjustable period, with interest rates determined by economic indexes such as the Consumer Price Index. Most programs offering flexible mortgage loans also include rate caps that limit how much their interest rate can increase at each adjustment period and overall over the life of the loan – helping protect homeowners from potential monthly payment increases pushing them out of their home – so it is crucial that borrowers thoroughly understand all terms before taking one out.

ARM Payments

Adjustable rate mortgages (ARMs) can help you qualify for home loans with lower interest rates than fixed-rate loans; however, you should understand how your payments will change when the initial fixed period ends.

Your ARM interest rate is calculated with two key components in mind: an index and a margin. Your lender will decide which index they use, typically offering three options.

Your adjustable rate mortgage (ARM) formula consists of two numbers that limit how much your rate can increase during each adjustment period and over its life. The first of these, known as the periodic cap, limits how much it can go up during each adjustment period; the second is the lifetime cap, which limits how much more your rate can go up during your loan term.

Some adjustable rate mortgages (ARMs) feature a “limited” payment option that enables you to pay less than the interest due each month, adding the unpaid portion directly onto your loan balance. While this practice was popular before the housing crisis, its use can become problematic if house values decline rapidly.
