存款利息怎么算

To calculate the interest on a deposit, you can use the formula:

Interest = Principal * Rate * Time

Where:
- Principal is the initial amount of money deposited
- Rate is the annual interest rate (expressed as a decimal)
- Time is the number of years the money is deposited for

For example, if you have $1000 deposited in a savings account with an annual interest rate of 5% for 2 years, the interest earned would be calculated as:

Interest = $1000 * 0.05 * 2 = $100

So, in this case, the interest earned on the deposit would be $100.
