How Savings Interest Works in the UK

In the UK, savings interest is typically calculated using simple interest for short-term savings and compound interest for longer-term savings. Most standard savings accounts use simple interest, which means your interest is calculated only on the original principal amount.

The basic formula for simple interest is:

Where:

• Principal is the amount of money you're saving
• Rate is the annual interest rate (expressed as a decimal)
• Time is the number of years the money is saved

For example, if you save £1,000 at 1.5% interest for 2 years, you would earn £30 in interest.

The Formula

The calculator uses the following formula to calculate savings interest:

Where:

• Principal = The initial amount of money you deposit
• Rate = The annual interest rate (as a percentage)
• Time = The number of years the money is saved

This formula assumes simple interest, which is common for standard savings accounts in the UK.

Worked Example

Let's say you want to save £5,000 at an interest rate of 2% for 3 years. Here's how the calculation works:

So, you would earn £300 in interest over 3 years, bringing your total savings to £5,300.

You can try this example in the calculator by entering £5,000 as the deposit amount, 2% as the interest rate, and 3 years as the term.
