Mortgage Overpayment Savings: How Much Could You Save? (2026)

Last updated: 13 October 2026

By Stiv · Design, technology and personal finance

I've overpaid my own mortgage through Sprive every month since October 2021, starting at £100 a month. This post is based on that real use and real numbers.

Most people know they should overpay their mortgage. Almost nobody knows by how much, or what it actually saves them. So we built a free mortgage overpayment calculator to find out. Then we ran our own numbers through it. The mortgage overpayment savings took us by surprise. We've since added a compare-to-savings toggle so you can see whether overpaying or saving the same money comes out ahead at your specific rates.

Sprive vs Plum vs Chip: Honest Comparison (2026)

Last updated: 13 October 2026

By Stiv · Design, technology and personal finance

I've used Sprive since October 2021, making monthly overpayments on my mortgage through the app. This comparison is based on that real use alongside Chip and Plum.

Sprive vs Plum vs Chip is the question that keeps coming up whenever anyone in the UK talks about saving money automatically. All three apps promise to do the hard bit for you. But they are not the same thing, and picking the wrong one means you are either missing features you need or paying for ones you do not. Here is how they actually compare after months of using all three.

Between the team, we run all three. Sprive handles mortgage overpayments. Chip is our primary auto-saver. Plum runs alongside Chip so we can see how the two compare in real life. Each has earned its place on someone's home screen, but for very different reasons.

Some apps in this comparison offer investing features, which carry risk including the possible loss of capital. Your home may be repossessed if you do not keep up repayments on your mortgage.

Overpay Mortgage or Invest? UK Guide to the Right Call (2026)

Last updated: 13 October 2026

By Stiv · Design, technology and personal finance

We faced this decision ourselves. Since October 2021 I've overpaid my mortgage every month through Sprive, first with Nationwide and now with Halifax, and the total reached £10,237.41 by 13 October 2026. This guide covers how we thought through the trade-off and what factors are worth considering.

Should you overpay your mortgage or invest the spare cash instead? It's one of the biggest personal finance questions UK homeowners face right now, and the answer isn't as obvious as either side would have you believe. With the Bank of England base rate at 3.75% (held 17 September 2026; next decision 5 November 2026, per the Bank of England), average two-year fixed mortgage rates around 5.64% as of early June 2026 (source: Moneyfacts), and top savings accounts paying around 4.75%, the maths is closer than it has been in years. This guide walks through the key factors, the trade-offs, and a practical framework to help you decide what makes sense for your situation. Our free mortgage overpayment calculator now also has a compare-to-savings toggle, so you can run both sides of one of those scenarios in seconds.

Brands don't choose what I feature or what I say about them. This is information, not financial advice, and CoolCuration is not authorised by the Financial Conduct Authority.

Capital at risk. The value of investments can go down as well as up and you may get back less than you invested. Past performance is not a reliable indicator of future results.

What Is Sprive, and How Does the App Work? (UK Guide 2026)

Last updated: 24 October 2026

By Stiv · Design, technology and personal finance

I've used Sprive since October 2021, with Nationwide and now Halifax as my lender. This guide is based on the actual setup process and daily use since then.

How does the Sprive app work? You link a current account and your mortgage, then set a monthly saving range. Sprive collects money by direct debit into a safeguarded balance, based on your spending. With one tap, that balance goes to your lender as an overpayment. Cashback from gift cards bought in the app adds to the same pot.

The one thing to check first is your lender's overpayment allowance, usually 10% of the balance a year on a fixed rate. Go over it and you can pay an early repayment charge, so set the range with that limit in mind.
