What is an Interest Calculator?
An interest calculator is a digital tool used to calculate interest on money saved or borrowed.

How to Use Our Interest Calculator UK
Using our interest calculator UK is simple. Just enter a few basic details:
Principal amount – This is the amount you are saving or borrowing.
Interest rate – Enter the annual interest rate.
Time period – Input the duration in months or years.
Interest type – Choose between simple or compound interest.
After entering these values, the calculator instantly shows the interest accrued and the total amount.
For example, if you invest £5,000 at an annual rate of 4% for 3 years, our savings interest calculator will tell you how much your savings will grow, both with and without compounding.
Types of Interest You Can Calculate
1. Simple Interest
Simple interest is calculated only on the principal amount. It is straightforward and commonly used for short-term loans or investments.
Formula: Simple Interest = (Principal × Rate × Time) ÷ 100
Our interest calculator UK allows you to input your values and instantly calculate interest without doing the math manually.
2. Compound Interest
Compound interest takes into account both the principal and the interest that has already been added. This is more common for savings and investment accounts in the UK.
Formula: Compound Interest = Principal × (1 + Rate ÷ n) ^ (n × Time) – Principal
The tool can function as a savings interest calculator, showing you how your money grows faster with compounding.
