Fitted our needs perfectly

We were looking for a new ISA and savings account following our house purchase and as an avid Money Saving Expert reader noticed how impressive Moneybox was. They fitted our needs perfectly Reviewed on: 5th February 2025

My life changing experience with moneybox

I used to have a terrible savings culture. No matter how much I earned, I had nothing to show for it. Every month, I would spend every penny, leaving me with an empty account and a nagging sense of regret. I told myself that saving was something I would do “later”—but later never came. That all changed when I discovered MoneyBox last year. At first, I was skeptical. I had tried saving before, but it always felt impossible. However, MoneyBox made it effortless. The simple round-ups, the easy-to-use features, and the ability to save without feeling the burden of a drastic lifestyle change made all the difference. For the first time in my life, I watched my savings grow—steadily, consistently, and without stress. I started small, but with time, I realized I had built up an amount that I was truly proud of. More than just money in my account, this was proof that I had changed. MoneyBox didn’t just help me save—it transformed my mindset. Looking back, I cannot believe how far I have come. What once felt impossible is now a reality. I finally have a savings habit I can be proud of, and I owe it all to MoneyBox. Thank you for creating something that truly makes a difference!

MoneyBox is a great way to save for the future.

MoneyBox is a great way to save for the future. The app is very easy to use. It guides you through the whole process and even has different tools to help you save and manage your money. I opened my Cash ISA through the app in a matter of minutes. The process was super easy and there are lots of options to choose from on how to save your money, like setting up a direct debit so you can save a certain amount each month. I would highly recommend it to anyone who is looking to save money tax free! They also offer the best interest rate on the market, for your Cash ISA tax free savings up to £20,000 each tax year. You can watch your money grow daily on the app and it even gives you a guide on how much your money could be worth in the future if you continue to save. There are lots of other handy tools on the app to help save and reach your goals. I'm so glad I opened an account with MoneyBox and they also offer the fantastic Lifetime ISA where you can earn upto £1000 interest each year all tax free. Don't hesitate even if your are starting small and watch your money grow. Reviewed on: 5th February 2025
