35 Best Free Online Mortgage Overpayment Calculator Websites

Here is a list of the best free online mortgage overpayment calculator websites. A mortgage is a long-term loan that you have to pay over a certain period of time. You have to regularly pay recurring monthly repayments. Since it does charge a rate of interest so you also have to pay that interest on top of the principal amount. But if you have extra money at times, you can pay that towards your mortgage. This can help you save a decent amount of interest on your mortgage repayments.

There are two types of mortgage overpayment. The first one is to overpay your recurring mortgage repayments. For example, if your current recurring repayment is $1000, you can pay $1500. Along with recurring overpayment, you can also pay a lump sum amount. You have the choice to pay the recurring overpayment, a lump sum, or both. This reduces the remaining mortgage repayment period. However, it does not impact the remaining recurring repayment amount.

The second mortgage overpayment type is where you can pay the interest on the mortgage. This can also be a one-time payment, recurring payment, or both. Paying the interest reduces the recurring repayments amount while keeping the original mortgage term.

This post covers 35 free websites with mortgage overpayment calculators. It’s a combination of calculators for both mortgage overpayment types supporting multiple payment options. The overview table below briefs you on all these calculators. From there, you can jump to any calculator to read more and get the link to the Calculator itself.

My Favorite Online Mortgage Overpayment Calculator

I like NatWest.com’s mortgage overpayment calculator. This calculator works for repayment as well as for interest. It offers multiple payment options and generates a mortgage comparison table at the end. However, the selection of a calculator totally depends on the types of overpayment and what you want in the output. You can refer to the table and go through the post to find a calculator suitable for your specific needs.
