Building a Free Mortgage Overpayment Calculator for UK Homeowners

I recently built Mortgage Overpayment Calculator, a free tool designed to help UK homeowners understand the financial impact of making extra mortgage payments.

The idea came from a simple problem: it can be difficult to see exactly how regular or one-off overpayments could affect the total interest paid and the time needed to repay a mortgage.

The calculator lets users explore different overpayment scenarios and understand the potential savings before making a decision. I’m also building practical guides around mortgage overpayments and mortgage repayment strategies.

You can try it here:

I’d really appreciate feedback from anyone interested in personal finance, mortgages, or building useful financial tools.
