Calculators

Weighing your options? We're right there with you.

These powerful tools can help you make good financial decisions.

Our collection of calculators can give you the answers you need to choose between mortgage options, plan for refinancing, or track the growth of your savings. We’re here to help you get where you want to be.

Mortgage Calculator

Use this mortgage calculator to determine your monthly payment and estimate the time needed to pay off your home loan. You'll see how much interest you could pay and your estimated principal balances. And if you're looking to get ahead, enter prepayment amounts to calculate their positive impact on your mortgage.

Adjustable-Rate vs. Fixed-Rate Mortgage Calculator

Use this calculator to compare a fixed-rate mortgage with an adjustable-rate. When your rate is fixed, your principal and interest payments remain the same for the entire term of the loan. An adjustable-rate mortgage (ARM) has a rate that can change, making your monthly payment increase or decrease.

Certificate of Deposit Calculator

Middlesex has CDs available in a range of terms and interest rates that fit your savings goals. To see what your estimated earning potential is, enter in information about your deposit amount, annual percentage yield (APY), and term. You can also run a detailed report to see a schedule of your CD's balance and interest earned over time.

Savings Calculator

Consistent deposits over a number of years can lead to strong savings because even small additions add up over time. This calculator shows how compound interest can work for you.
