High yield savings accounts offer competitive interest rates compared to traditional savings accounts. This calculator helps you estimate your potential earnings from a high yield savings account by considering your principal amount, annual percentage yield (APY), and compounding frequency.
How to Use This Calculator
To calculate your high yield savings account earnings:
- Enter the principal amount (the initial deposit you plan to make).
- Select the annual percentage yield (APY) offered by the savings account.
- Choose the compounding frequency (typically daily, monthly, or annually).
- Enter the term length in years.
- Click "Calculate" to see your estimated earnings.
The calculator will display your total earnings and the final amount in the account after the specified term.
Formula Used
The earnings from a high yield savings account are calculated using the 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 unit t
- t = the time the money is invested or borrowed for, in years
For this calculator, we use the APY as the annual interest rate (r). The compounding frequency (n) is typically daily (365), monthly (12), or annually (1).
Worked Example
Suppose you deposit $1,000 in a high yield savings account with a 4.5% APY compounded daily. After 5 years, your earnings would be calculated as follows:
A = 1000 × (1 + 0.045/365)^(365×5)
A ≈ 1000 × (1.0001228)^1825
A ≈ 1000 × 1.228
A ≈ $1,228.00
Your total earnings would be $228.00.
This example shows how compound interest can grow your savings over time, even with a relatively low interest rate.
