Example Calculation
Let’s assume:

- Due date: 1st January
- Payment date: 10th January
- Grace period: 2 days
- Fee type: Daily at 1%
Days late: 9
Grace days: 2
Billable late days: 7
Late fee = $500 × 1% × 7 = $35
Total due = $535
This helps you understand your penalty clearly before paying.
Types of Late Fee Methods Explained
Flat Fee
A fixed amount added once, no matter how late the payment is.
Example: $25 late charge after missing due date.
Percentage Fee
A percentage of the original amount is added.

Daily Accrual
Fee grows every day after grace period.
