3 Savings Account Calculator

Compare three savings accounts to find the best option for your needs. Our calculator helps you evaluate interest rates, fees, and features to make an informed decision about where to park your savings.

How to Use This Calculator

Using our 3 savings account calculator is simple. Follow these steps to get the most accurate comparison:

Enter the principal amount you want to compare across all three accounts.
Input the annual interest rates for each account.
Specify the compounding frequency (annually, semi-annually, quarterly, monthly).
Enter the term length in years for each account.
Add any monthly fees for each account.
Click "Calculate" to see the results.

The calculator will show you the future value of each account, the total interest earned, and the net result after fees. You can also visualize the growth over time with the included chart.

Example Calculation

Let's compare three savings accounts with $1,000 initial deposits:

Account 1: 2.5% APR, monthly compounding, 5 years, $2/month fee
Account 2: 3.0% APR, quarterly compounding, 5 years, $1/month fee
Account 3: 2.8% APR, annually compounding, 5 years, $3/month fee

After running these numbers through the calculator, you'll see that Account 2 provides the highest net return despite the lower interest rate due to its more frequent compounding and lower fees.

Formula Used

The calculator uses the compound interest formula to calculate the future value of each savings account:

Future Value (FV) = P × (1 + r/n)^(n×t)

Where:

P = Principal amount
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 fees are subtracted from the future value to calculate the net result.

This formula accounts for the time value of money, showing how compounding can significantly increase your savings over time. The calculator also considers monthly fees, which are subtracted from the future value to provide a more accurate comparison.

Comparison Example

Let's look at a detailed comparison of three savings accounts with different characteristics:

Account	APR	Compounding	Term	Monthly Fee	Future Value	Net Result
Account 1	2.5%	Monthly	5 years	$2	$1,132.68	$1,128.68
Account 2	3.0%	Quarterly	5 years	$1	$1,159.27	$1,158.27
Account 3	2.8%	Annually	5 years	$3	$1,142.46	$1,139.46

In this example, Account 2 provides the highest net return despite having a lower interest rate than Account 1. This is because of its more frequent compounding and lower monthly fee. Account 3, while having a higher interest rate than Account 1, is hurt by its less frequent compounding and higher monthly fee.

Remember that these are simplified examples. Real-world savings accounts may have different terms, fees, and interest rate structures. Always review the fine print and consider your specific financial situation before choosing an account.

Frequently Asked Questions

How does compounding affect my savings?

Compounding means that interest is earned on both your initial deposit and the accumulated interest from previous periods. More frequent compounding generally leads to higher returns over time, as shown in our comparison example.

Should I consider monthly fees when comparing accounts?

Yes, monthly fees can significantly impact your net return, especially over longer periods. Our calculator subtracts these fees from the future value to give you a more accurate comparison of the three accounts.

What's the difference between APR and APY?

APR (Annual Percentage Rate) is the simple annual interest rate, while APY (Annual Percentage Yield) takes into account the effect of compounding. APY is generally higher than APR for accounts with frequent compounding.
