Example Calculation
Let’s understand how the calculator works with a real-life example:
- Current Balance: $2,000
- Annual Interest Rate: 18%
- Time Period: 12 months
Step 1: Convert Annual Rate to Monthly Rate
18% ÷ 12 = 1.5% per month
Step 2: Calculate Interest
Interest = Balance × Monthly Rate × Months
= 2000 × 0.015 × 12
= $360
Step 3: Calculate Total Payable
Total = Balance + Interest
= 2000 + 360
= $2,360
Final Result:
- Interest Paid: $360
- Total Payable: $2,360
This shows how quickly interest adds up if you carry a balance for a long time.
