The graph on our landing page compares the historic returns generated from earning interest in a typical, high-street bank savings account, against the investment funds offered by Plum. These illustrate the power of compound interest, and the potential benefits of investing for the long-term.

It is important to be aware that, whilst we’ve sought to compare the differing returns offered, these two options represent very different levels of risk. A bank account and an investment fund are two separate financial products with different levels of risk. In addition, a bank account is covered by the Financial Services Compensation Scheme (FSCS) whereas investing with Plum is not FSCS protected. When investing, your capital is at risk. Therefore, we are not comparing financial products but only illustrating the differences in potential interest to be earned with plum.

Our findings show that the average return offered by a bank savings account was 0.03%. When compared to the 5-year performance of the investment funds offered by Plum, we see a far greater return (albeit with differing risk levels). A breakdown of this performance and more details on the funds in general can be found here.
