To aid in this decision-making, the 10/1 ARM vs 30-Year Fixed Calculator serves as a valuable tool. This calculator assists potential homebuyers in comparing the long-term stability of a fixed-rate mortgage with the initial lower interest rates offered by a 10/1 ARM.

Formula:

1. 30-Year Fixed Mortgage Payments:P=1−(1+r)−ntr×PV​ where $P$ is the monthly payment, $r$ is the monthly interest rate, $PV$ is the present value or loan amount, $n$ is the total number of payments (360 for a 30-year term), and $t$ is the time in years.
2. 10/1 ARM Initial Payments: 1−(1)−P=1−(1+r)−ntr×PV​ The formula is the same as the 30-year fixed mortgage, but the interest rate is the initial fixed rate for the first 10 years.
