More information about the Plum Interest calculator

Learn more about how the Plum Interest calculator works, including fees and tax considerations.

What is the Plum Interest calculator?

The Plum Interest calculator shows what your return might look like, based on the amount you could potentially invest in the future (though keep in mind it uses the current return).

It works by asking you to input the amount you could invest each month, along with the amount you wish to contribute as an initial lump sum. It then uses the current Plum Interest yield to calculate a potential projected return on your money.

You can also project your potential Plum Interest returns over different time periods, and see an example of what you could buy with these potential returns.

Plum Interest is an investment product, so your capital is at risk. A projection is not a reliable indicator of future returns. The projection from this calculator is based on your input and so is not a reliable indicator of future results. This means it cannot guarantee what your investments will actually be worth.

How we take charges into account

The potential earnings figures shown in the Plum Interest calculator assume annual service and fund charges of 0.25% in the UK and 0.30% in the EU, and are shown after charges (net).

How future interest rates may affect your returns

In the UK, the Bank of England’s base rate has been increasing since January 2022. The interest rate for Plum Interest will tend to follow any changes to the base rate.

This means that the interest rate shown in the Plum Interest calculator may increase or decrease, in line with any changes in the base rate. You can see how the Bank of England base rate has changed over time from the chart below.

You should anticipate that the return Plum Interest offers is likely to change in the future, in line with changes in the Bank of England base rate.

How inflation might affect your returns

The potential return projection shown in the Plum Interest calculator doesn’t account for inflation. You should consider how this may affect the value of your money before investing.

Inflation means that money loses spending power because prices rise. So, even if the value of your investments does grow, your money may be worth less over time if you can’t outpace inflation. More info on the current UK rate of inflation can be found here.

The example purchases provided in the Plum Interest calculator are for reference only. These equivalent purchases, based on the current return, may not be accurate once future inflation is taken into account.

How tax might affect your returns

If you earn any interest while holding money in Plum Interest, you may need to pay tax on the annual interest earned in accordance with UK tax laws and regulations.

Plum is not able to give personalised tax advice, and your tax liability will depend on your own individual circumstances.
