Example Calculation

Let’s walk through an example to illustrate how this calculator works:

Principal Amount: $10,000
Interest Rate: 5% per year
Time Period: 3 years

Step 1: Calculate Interest
Interest = (Principal × Rate × Time) / 100
= (10,000 × 5 × 3) / 100
= $1,500

Step 2: Calculate Total Payable
Total Payable = Principal + Interest
= 10,000 + 1,500
= $11,500

So, for a $10,000 loan at 5% annual interest over 3 years, the interest accrued will be $1,500, and the total amount payable at the end of the term will be $11,500.
