The calculator will display the future value of your savings, the total interest earned, and a growth chart showing how your savings grow over time.

How Savings Account Growth Works

Savings accounts typically offer a fixed interest rate, which is compounded over time. Compound interest means that interest is earned on both your initial deposit and the accumulated interest from previous periods.

The more frequently interest is compounded, the more your savings will grow over time. For example, monthly compounding will yield slightly more interest than annual compounding for the same annual rate.

Note: The actual growth of your savings may vary based on market conditions and changes in interest rates. This calculator provides an estimate based on the inputs you provide.

The Formula

The future value (FV) of your savings can be calculated using the compound interest formula:

FV = P × (1 + r/n)^(n×t)

Where:

FV = Future Value
P = Principal amount (initial deposit)
r = Annual interest rate (in decimal)
n = Number of times interest is compounded per year
t = Time the money is invested for (in years)

The total interest earned is calculated as:

Interest = FV - P

Worked Examples

Example 1: Annual Compounding

If you deposit $1,000 at an annual interest rate of 5% compounded annually for 10 years:

FV = 1000 × (1 + 0.05/1)^(1×10) = 1000 × 1.62889 = $1,628.89

Total interest earned: $1,628.89 - $1,000 = $628.89

Example 2: Monthly Compounding

If you deposit $1,000 at an annual interest rate of 5% compounded monthly for 10 years:

FV = 1000 × (1 + 0.05/12)^(12×10) = 1000 × 1.64701 = $1,647.01

Total interest earned: $1,647.01 - $1,000 = $647.01

Frequently Asked Questions

How does compound interest work?: Compound interest means that interest is earned on both your initial deposit and the accumulated interest from previous periods. This causes your savings to grow exponentially over time.
What is the difference between APR and APY?: APR (Annual Percentage Rate) is the simple annual interest rate, while APY (Annual Percentage Yield) is the actual annual rate of return taking into account compounding. APY is always higher than APR for the same interest rate.
How often should interest be compounded for maximum growth?: The more frequently interest is compounded, the more your savings will grow. Most savings accounts offer daily or monthly compounding, which provides slightly better returns than annual compounding.
Is this calculator accurate for my specific savings account?: This calculator provides an estimate based on the inputs you provide. For precise calculations, consult your bank or financial institution, as they may offer different terms and conditions.
Can I use this calculator for retirement planning?: While this calculator can help estimate future savings growth, it's not a substitute for professional financial advice. Consider consulting with a financial advisor for retirement planning.
