أقساط

A program to manage monthly installments, including adding customers and multiple bills.

The ratio is calculated by the following equation:
The percentage in the number of months = the total added percentage
Total percentage added in total amount = amount added
The added amount plus the total amount = the amount after adding the percentage
The amount after adding the percentage divided by the number of months

Example:
5%
The amount is 100,000
Number of months 5

5% in 5 months = 25%
25% in 100,000 = 25,000
25,000 + 100,000 = 125,000
125,000 / 5 months = 31,250
