Plum Interest

What is Plum Interest?

Plum Interest invests in a sterling short-term Money Market Fund (MMF), provided by BlackRock. It’s separate from our easy access interest-bearing Pockets that are provided by Investec Bank Plc.

Investing in money market funds is a way to access a diversified investment portfolio that is professionally managed. Plum Interest only contains high-quality investments, like interest-generating government bonds.

The aim is to deliver a better return than you might expect to receive in a current account from a high-street bank.

Capital at risk. Returns are not guaranteed.

Calculate the power of compounding

The yield we quote for Plum Interest is shown after fees (net), so you can be clear what you’re going to get.

Because any returns are reinvested, it means you can take advantage of compound investments. The process where you could also earn a return on any previous earnings, in addition to the principal amount invested.

Our calculator takes compounding into consideration when you calculate your potential Plum Interest earnings.

What are the benefits of Plum Interest?

The main benefit of Plum Interest is that it tends to track the Bank of England base rate. So it’ll typically yield a higher return than you might expect to receive in a current account from a high-street bank.

It contains low-risk investments, because it only includes robust companies and governments. So they’re among some of the safest available. 

In addition, only short-term assets are selected, reducing uncertainty and increasing stability.

Capital is at risk if you invest. Forecasts are not a reliable indicator of future performance. For further detail about tax implications of this product, click here.

The %* annual variable return we provide is a net rate. That means the rate we show you already includes the annual fee of 0.25%, based on the daily balance that you hold in your Plum Interest pocket, and you know exactly what you're getting. Learn more here.
