How Savings Interest Rates Work

Savings interest rates in the UK are typically offered by banks and building societies. These rates can be fixed or variable, and they determine how much interest you earn on your savings.

Simple Interest

Simple interest is calculated only on the original principal amount. The formula for simple interest is:

Interest = Principal × Rate × Time

Where:

Principal = the initial amount of money
Rate = the annual interest rate (in decimal form)
Time = the time the money is invested for (in years)

Compound Interest

Compound interest is calculated on the initial principal and also on the accumulated interest of previous periods. The formula for compound interest is:

Amount = Principal × (1 + Rate/Compounding Periods)^(Rate × Time)

Where:

Principal = the initial amount of money
Rate = the annual interest rate (in decimal form)
Time = the time the money is invested for (in years)
Compounding Periods = how often the interest is compounded (e.g., annually, monthly)

Example Calculation

Let's say you save £1,000 at a fixed interest rate of 2% per year for 5 years with compound interest, compounded annually:

Amount = £1,000 × (1 + 0.02/1)^(0.02 × 5) Amount = £1,000 × (1.02)^0.1 Amount ≈ £1,104.08

You would earn approximately £104.08 in interest over 5 years.
