If £ 3000 £ 3000 £3000 Is Placed Into A Bank Account That Pays 4 % 4\% 4% Compound Interest Per Year, How Much Will Be In The Account After 2 Years?
Introduction
Compound interest is a powerful financial concept that allows your savings to grow exponentially over time. When you place money into a bank account that pays compound interest, the interest earned is added to the principal amount, and then the interest is calculated on the new total. This process repeats annually, resulting in a significant increase in the account balance. In this article, we will explore how compound interest works and calculate the future value of an investment using a simple example.
What is Compound Interest?
Compound interest is a type of interest that is calculated on both the initial principal amount and the accumulated interest from previous periods. It is a key concept in finance and is used to calculate the future value of investments, loans, and other financial instruments. The formula for compound interest is:
A = P(1 + r/n)^(nt)
Where:
- A is the future value of the investment/loan
- P is the principal amount (initial investment)
- r is the annual interest rate (in decimal form)
- n is the number of times that interest is compounded per year
- t is the time the money is invested for, in years
Example: Calculating Compound Interest
Let's consider an example to illustrate how compound interest works. Suppose you deposit into a bank account that pays compound interest per year. We want to calculate the future value of this investment after 2 years.
Step 1: Identify the variables
- P = (initial investment)
- r = = (annual interest rate)
- n = 1 (compounded annually)
- t = 2 years
Step 2: Plug in the values
Using the compound interest formula, we can plug in the values as follows:
A = 3000(1 + 0.04/1)^(1*2) A = 3000(1 + 0.04)^2 A = 3000(1.04)^2 A = 3000 * 1.0816 A =
