Calculate your potential earnings from a Bank of America savings account using our free online calculator. Understand how interest rates, deposit amounts, and compounding periods affect your savings growth.
How the Calculator Works
The Bank of America Savings Account Interest Rate Calculator uses the compound interest formula to determine how much your savings will grow over time. The formula accounts for both simple and compound interest calculations, depending on your selection.
Compound Interest Formula
A = P(1 + r/n)^(nt)
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
Note
Bank of America typically offers compound interest on savings accounts, meaning your interest is calculated on both the initial principal and the accumulated interest of previous periods.
How to Use This Calculator
- Enter your initial deposit amount in the "Principal" field.
- Select your current Bank of America savings account interest rate from the dropdown menu.
- Choose how often your interest is compounded (annually, quarterly, monthly, etc.).
- Enter the number of years you plan to keep your money in the savings account.
- Click "Calculate" to see your projected balance.
- Review the results and chart showing your savings growth over time.
Understanding Interest Types
There are two main types of interest calculations:
Simple Interest
Simple interest is calculated only on the original principal amount. It doesn't grow over time. The formula is:
A = P(1 + rt)
Compound Interest
Compound interest is calculated on the initial principal and also on the accumulated interest of previous periods. This is what most savings accounts use. The formula is:
A = P(1 + r/n)^(nt)
Bank of America Note
Bank of America savings accounts typically compound interest quarterly, meaning your balance grows four times a year.
How Compounding Works
Compounding is the process of earning interest on both your initial deposit and the accumulated interest from previous periods. The more frequently interest is compounded, the faster your money grows.
For example, with a 5% annual interest rate compounded quarterly:
- After 1 year: $1,051.16
- After 2 years: $1,104.71
- After 5 years: $1,282.94
Notice how the growth accelerates over time due to compounding.
Worked Example
Let's calculate the future value of $5,000 deposited in a Bank of America savings account with a 1.20% annual interest rate compounded quarterly over 10 years.
- Principal (P) = $5,000
- Annual interest rate (r) = 1.20% or 0.012
- Compounding frequency (n) = 4 (quarterly)
- Time (t) = 10 years
Using the compound interest formula:
A = 5000(1 + 0.012/4)^(4*10) = 5000(1.003)^40 ≈ $6,236.72
After 10 years, your $5,000 deposit would grow to approximately $6,236.72 with compound interest.
Interest Earned
Total interest earned = $6,236.72 - $5,000 = $1,236.72
