Practical Example

Let’s assume:

• Principal Amount: $10,000
• Annual Penalty Rate: 12%
• Start Date (Due Date): January 1, 2024
• End Date (Payment Date): March 1, 2024
• Penalty Type: Simple Interest

Calculation:

• Days late = 60
• Simple Interest = Principal × Rate × (Days / 365)
• = $10,000 × 12% × (60 / 365)
• ≈ $197.26 penalty

Total to Pay = $10,197.26

This demonstrates how quickly the tool can generate accurate penalty results without manual math.
