Compound Interest Calculator
Introduction
Welcome to our Compound Interest Calculator tool! This calculator is designed to help you understand the power of compound interest and how it can grow your investments over time. Whether you are planning for retirement, saving for a major purchase, or just curious about how your money can grow, our tool will provide you with accurate and easy-to-understand results.
What is Compound Interest?
Compound interest is the interest on a loan or deposit calculated based on both the initial principal and the accumulated interest from previous periods. Unlike simple interest, which is calculated only on the principal amount, compound interest allows your investment to grow faster because it includes interest on interest.
How Does Compound Interest Work?
The formula for compound interest is: A=P(1+rn)ntA = P \left(1 + \frac{r}{n}\right)^{nt}A=P(1+nr)nt
Where:
- AAA is the future value of the investment/loan, including interest
- PPP is the principal investment amount (initial deposit or loan amount)
- rrr is the annual interest rate (decimal)
- nnn is the number of times that interest is compounded per year
- ttt is the number of years the money is invested or borrowed for
How to Use Our Calculator
Using our Compound Interest Calculator is simple. Follow these steps:
- Initial Investment Amount: Enter the amount of money you are starting with.
- Annual Interest Rate (%): Enter the annual interest rate as a percentage.
- Number of Years: Enter the number of years you plan to keep the money invested or borrowed.
- Compounding Frequency: Choose how often the interest is compounded (e.g., yearly, semi-annually, quarterly, monthly).
Example
Let’s say you have £1,000 to invest at an annual interest rate of 5%, compounded monthly, for 10 years. Here’s how you can calculate the future value using our calculator:
- Principal Investment (P): £1,000
- Annual Interest Rate (r): 5% or 0.05
- Number of Years (t): 10
- Compounding Frequency (n): 12 (monthly)
Using the formula: A=1000(1+0.0512)12×10A = 1000 \left(1 + \frac{0.05}{12}\right)^{12 \times 10}A=1000(1+120.05)12×10 A≈1000(1+0.004167)120A \approx 1000 \left(1 + 0.004167\right)^{120}A≈1000(1+0.004167)120 A≈1000(1.647)A \approx 1000 \left(1.647\right)A≈1000(1.647) A≈1647A \approx 1647A≈1647
After 10 years, your investment would grow to approximately £1,647.
