Accuracy You Can Trust

Tested against real mortgage statements and compared with tools delivering results accurate to the penny (allowing for minor rounding).

Why this exists

I built this tool to answer a simple question: How can I pay my mortgage off sooner — and what will it take?

This calculator reflects real UK mortgage behaviour and helps you explore realistic strategies with confidence.

Take control of your mortgage

This is a comprehensive suite of tools to help you make better and more informed decisions about how to reduce the term of your mortgage.

Using comparisons, strategies, simulations, and schedules, you get complete visibility and control over your mortgage. You can explore different approaches, see their impact, and choose the path that works for you.

The goal is simple: settle your mortgage sooner, save on interest, and free up your income to spend on what matters most to you — instead of being burdened by your monthly payment.
