Running the Numbers on Refinancing
Deciding whether or not to refinance an existing mortgage typically means running some numbers. You can do this on your own, but it’s helpful to get the professional assistance of a loan officer. It mostly boils down to how much you’ll save each month, but there are other considerations.
First, the change in rate isn’t everything. Old school rules say that it’s a good idea to refinance if current market rates are 1% or 2% lower than what you currently have, but the rate is only a part of it. The other component is the amount being financed. For larger loan amounts, a reduction of only 0.5% might make sense. For smaller loan amounts, 2% may not be enough.
Instead, calculate the monthly savings and then divide that amount into the closing costs associated with the mortgage. The result is how many months it will take to ‘recover’ the closing costs in the form of monthly savings. Pay less attention to the actual rate but instead how long it will take to get your closing costs back.
Take a loan amount of $300,000 over 30 years with a rate of 4.50%. The principal and interest payment works out to $1,520 per month. If current market rates are at 3.5%, the new payment would be $1,347 for a savings of $173 per month. If closing costs were $3,000, then it would take just over 17 months to recover the associated fees. Not bad. If the loan amount were $100,000 under the same scenario, the monthly savings would be $57 and recovered in 52 months, or more than four years. Probably not a good idea in that situation.
There are other considerations outside of month-to-month savings. Let’s say you’re less concerned about lowering your monthly payments, and you’re more interested in paying off your house faster. In this scenario, it may make sense to refinance at an even lower interest rate on a 15-year mortgage. You’ll pay more per month, but you can potentially save tens of thousands of dollars over the life of your loan.
