This calculator helps you estimate how much you'll earn with a 0.5% APY savings account. Simply enter your initial deposit and the time period, then see your projected earnings and total balance.
How to Use This Calculator
Using this calculator is simple:
- Enter your initial deposit amount in the "Initial Deposit" field.
- Select the time period for your savings (in years).
- Click "Calculate" to see your projected earnings and total balance.
- Review the assumptions and formula used for the calculation.
The calculator uses compound interest to estimate your earnings. Compound interest means you earn interest on both your initial deposit and the accumulated interest over time.
Formula Explained
The calculation uses the compound interest formula:
Compound Interest Formula
Future Value = Initial Deposit × (1 + APY/100)^Time Period
Earnings = Future Value - Initial Deposit
Where:
- Initial Deposit is the amount you start with
- APY is the annual percentage yield (0.5% in this case)
- Time Period is the number of years your money will grow
The calculator assumes the interest is compounded annually, which is typical for savings accounts.
Worked Example
Let's say you deposit $1,000 in a savings account with a 0.5% APY for 5 years.
Using the formula:
Calculation Steps
Future Value = $1,000 × (1 + 0.5/100)^5
Future Value = $1,000 × (1.005)^5
Future Value = $1,000 × 1.02538
Future Value = $1,025.38
Earnings = $1,025.38 - $1,000 = $25.38
After 5 years, you would have $1,025.38 with $25.38 in earnings.
Comparison Table
This table compares the growth of different initial deposits with a 0.5% APY over 5 years.
| Initial Deposit | Earnings After 5 Years | Total Balance |
|---|---|---|
| $1,000 | $25.38 | $1,025.38 |
| $5,000 | $126.92 | $5,126.92 |
| $10,000 | $253.85 | $10,253.85 |
| $25,000 | $634.62 | $25,634.62 |
As you can see, even with a low APY, your money grows over time. The longer you leave your money in the account, the more it grows.
