Savings Account Balance Calculator

Track your savings account balance over time with our free online calculator. Whether you're saving for a goal or just want to understand how compound interest works, this tool helps you visualize your savings growth.

How to Use This Calculator

Using the savings account balance calculator is simple. Follow these steps:

Enter your initial deposit amount in the "Initial Deposit" field.
Specify the monthly contribution amount in the "Monthly Contribution" field.
Input the annual interest rate in the "Annual Interest Rate" field.
Select the time period for your savings in the "Time Period" dropdown.
Click the "Calculate" button to see your projected balance.

The calculator will display your projected balance at the end of the selected time period, along with a chart showing your savings growth over time.

Formula Used

The savings account balance calculator uses the future value of an investment formula with regular contributions:

Future Value = P × (1 + r/n)^(nt) + PMT × (((1 + r/n)^(nt) - 1) / (r/n)) Where: P = Initial deposit PMT = Monthly contribution r = Annual interest rate (in decimal) n = Number of times interest is compounded per year (12 for monthly) t = Time period in years

This formula accounts for both the initial deposit and regular contributions, with interest compounded monthly.

Worked Example

Let's calculate the future value of a savings account with these parameters:

Initial deposit: $1,000
Monthly contribution: $200
Annual interest rate: 5%
Time period: 10 years

Using the formula:

Future Value = 1000 × (1 + 0.05/12)^(12×10) + 200 × (((1 + 0.05/12)^(12×10) - 1) / (0.05/12)) Future Value ≈ $37,370.42

After 10 years, your savings account would be worth approximately $37,370.42.

Interpreting Results

The calculator provides several key pieces of information:

Projected Balance: The total amount in your savings account at the end of the selected time period.
Total Contributions: The sum of your initial deposit and all regular contributions.
Total Interest Earned: The difference between the projected balance and total contributions.

Use this information to understand how your savings are growing over time and how much of that growth comes from interest earnings.

Remember that these are projections based on current interest rates and contributions. Actual results may vary due to market conditions and changes in your savings plan.
