贷款利率计算方法

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

Total Interest = Principal Amount x Interest Rate x Time

Where:
- Principal Amount is the initial amount borrowed
- Interest Rate is the annual interest rate (expressed as a decimal)
- Time is the duration of the loan in years

For example, if you borrow $10,000 at an annual interest rate of 5% for 3 years, the total interest would be calculated as follows:

Total Interest = $10,000 x 0.05 x 3 = $1,500

So, the total amount to be repaid would be the principal amount plus the total interest:

Total Amount = Principal Amount + Total Interest
Total Amount = $10,000 + $1,500 = $11,500

This is a simple way to calculate the interest on a loan based on the principal amount, interest rate, and duration of the loan.
