Formula Explained

The amount in an account can be calculated using the compound interest formula:

A = P × (1 + r/n)^(n×t) Where: A = the future value of the investment/loan, including interest P = the principal investment amount (the initial deposit or loan amount) r = the annual interest rate (decimal) n = the number of times that interest is compounded per year t = the time the money is invested or borrowed for, in years

This formula accounts for compound interest, which means your interest earns interest over time, leading to exponential growth of your account balance.

Worked Examples

Example 1: Simple Savings Account

Suppose you deposit $1,000 in a savings account with a 3% annual interest rate, compounded annually, for 5 years.

Using the formula:

A = 1000 × (1 + 0.03/1)^(1×5) A = 1000 × (1.03)^5 A ≈ 1000 × 1.159477 A ≈ $1,159.48

After 5 years, your account will be worth approximately $1,159.48.

Example 2: Investment with Quarterly Compounding

If you invest $5,000 at a 4% annual interest rate, compounded quarterly, for 10 years:

A = 5000 × (1 + 0.04/4)^(4×10) A = 5000 × (1.01)^40 A ≈ 5000 × 1.485947 A ≈ $7,429.74

With quarterly compounding, your investment grows to approximately $7,429.74 over 10 years.

Frequently Asked Questions

What is compound interest?

Compound interest is when interest is calculated on the initial principal and also on the accumulated interest of previous periods. This means your money grows exponentially over time rather than linearly.

How often should interest be compounded?

The more frequently interest is compounded, the faster your money grows. Annual compounding is common for savings accounts, while investments often offer quarterly or monthly compounding for better returns.

Is this calculator accurate for all types of accounts?
