Bankrate High Interest Savings Account Calculator

This Bankrate High Interest Savings Account Calculator helps you estimate your potential earnings from a high-yield savings account. By entering your deposit amount, interest rate, and time period, you can quickly see how much interest you could earn.

How the High Interest Savings Account Calculator Works

A high interest savings account calculator estimates your earnings based on simple interest principles. The calculator uses the basic interest formula:

Interest = Principal × Rate × Time

Where:

Principal is the initial amount of money you deposit
Rate is the annual interest rate (expressed as a decimal)
Time is the number of years the money will be in the account

The calculator then adds this interest to your principal to show your total balance at the end of the period.

Note: This calculator assumes simple interest. Some high-yield savings accounts may offer compound interest, which would result in higher earnings over time.

How to Use the Calculator

Enter the principal amount you plan to deposit in the "Initial Deposit" field
Input the annual interest rate offered by the savings account in the "Annual Interest Rate" field
Select the time period for your deposit from the dropdown menu
Click the "Calculate" button to see your estimated earnings
Review the results and use the chart to visualize your growth over time

The calculator will display:

Your estimated interest earnings
Your total balance after the selected time period
A chart showing your balance growth over time

The Formula Explained

The calculator uses the simple interest formula:

Total Balance = Principal + (Principal × Rate × Time)

Where:

Principal is the initial deposit amount
Rate is the annual interest rate divided by 100 (e.g., 3.5% becomes 0.035)
Time is the number of years the money will be in the account

For example, if you deposit $1,000 at 2% annual interest for 5 years:

Total Balance = $1,000 + ($1,000 × 0.02 × 5) = $1,000 + $100 = $1,100

Worked Example

Let's say you want to deposit $5,000 in a high interest savings account that offers a 3.25% annual interest rate. You plan to leave the money in the account for 3 years.

Using the calculator:

Enter $5,000 as the initial deposit
Enter 3.25 as the annual interest rate
Select "3 years" from the time period dropdown
Click "Calculate"

The calculator will show:

Estimated interest: $500.25
Total balance: $5,500.25

This means you would earn $500.25 in interest over 3 years, bringing your total balance to $5,500.25.

Remember: Actual earnings may vary slightly depending on the specific terms of the savings account and when interest is paid.
