How to use
- Set your currency label, grace days and maximum cap per book if your library uses them.
- Add one row per overdue book and enter its title, days overdue and fine rate per day.
- Press Calculate fines to see the breakdown and the total across all books.
- Enter the student name and press Print receipt to print or save the receipt as PDF.
Note: Chargeable days = days overdue minus grace days. If the result is zero or below, no fine is charged for that book.
Tips
- Grace days keep the system fair for students who return a book only slightly late.
- A maximum cap stops one lost or very late book from building an unfair penalty.
- Always give the student a printed receipt so the fee is clear and on record.
