Refinance ARM to Fixed Rate Mortgage

Do you have an adjustable rate mortage (ARM)? Do you want to protect yourself against rising interest rates? How do you know when the benefits of a refinance from an ARM to a fixed rate mortgage outweigh the costs? Let's learn from the mortgage calculator in this example.

The homeowner has paid 5 years of a 30 year adjustable rate mortgage for $120,000 with a starting interest rate of 4%. The index rate and margin are 1% and 3.5% respectively. The rates are fixed for the first 10 years. At the first adjustment the rates may change a maximum of 1%. Subsequent interest rates adjustment may change rates up to 1% every 12 months. The minimum interest rate for the mortgage is 4% while the maximum is 18%.

Use the refinance calculator to see how a refinance could benefit you.

Break-Even
The break-even point is the amount of time it will take for your mortgage savings to equal the amount you paid up front. The break-even point for your refinance is the amount of time it will take for your refinance savings to equal the cost of your refinance. The break-even for paying discount points is the amount of time it will take for your savings to equal the amount you paid for points
Cash Out
The amount of money the borrower will receive after closing the loan. This is more common for refinances than for purchases.
Floor Rate
Floor rate is the minimum interest rate for an adjustable rate mortgage (ARM).
Income Tax Rate
Your marginal income tax rate is the rate at which any additional dollars of your income would be taxed at.
Index Rate
Rate Adjustment on ARMs are based on the index rate, the margin, the adjustment schedule, interest rate caps, and floor rate specified in your loan documents. Index rates change over time. They should be published and widely available. Common indexes used for setting mortgage rates have include the Prime Rate, Libor (London Interbank Offer Rate) and U.S. Treasury Rates.
Interest
The portion of your mortgage payment that is due to the interest rate being applied to the principal balance. The Total Interest for a mortgage is the sum of all interest paid over the life of a loan.
Interest Rate
The percentage of the principal balance of your mortgage that determines how much interest you must pay. The interest rate on your mortgage may change or remain the same depending on the type of loan you have.
Interest Rate Adjustments
The interest rate changes on an adjustable rate mortage (ARM) during adjustment periods specified in your loan documents. Your interest rate may have a fixed period where it does not change followed by adjustements on a regularly scheduled basis. For example, the interest rate on a mortgage could be fixed for 2 years followed by adjustments every 6 months.
Interest Rate Caps
Limits how much your interest rate can be increased during each adjustment period for an ARM. The cap for the first adjustment period may be different than the cap on subsequent adjustments. There also may be a maximim overall cap on interest rate increases during the life of your loan.
Investment Earnings
Your investment earnings are the average annual percentage rate you expect to earn on your investments.
Loan Amount
The initial principal balance or your mortgage at closing.
Margin
When an ARM adjusts the margin is added to the index rate to help determine your interest rate. Interest rate caps and the floor rate for your mortgage may limit how much your actual interest rate changes. The margin typically is fixed for the life of the loan. It should be clearly specified in your loan documents.
Payment Shock
Occurs when the required minimum payment for a mortgage increases significantly. This can occur on adjustable rate mortgage when interest rates rise sharply, on interest-only mortgages when the interest-only period ends, and on balloon mortgages when the balloon payment is due.
Principal
The portion of your mortgage payment that is used to pay down the current balance of your mortgage. The principal balance represents how much you owe on the mortgage.
Refinance Fees
All closing costs for the new mortgage, including any discount points, loan origination fees, appraisal fees, title insurance, etc...
Refinance Savings/(Loss)
The refinance savings/(loss) estimates how a refinance will impact your financially.
Term
The amortization term is one of the key factors that determine your required mortgage payment. Your required mortgage payment for fully amortizing mortgages is the amount that would result in the mortgage being closest to being paid off by the end of the amortization term. Longer amortization terms result in lower required mortgage payments for fully amortizating mortgages, all other things being equal.
