أقساط

A program for managing monthly installments, which includes adding multiple clients and invoices.

The ratio is calculated with the following equation:
The percentage in the number of months = the total percentage added
The total percentage added in the total amount = the added amount
The added amount plus the total amount = the amount after adding the percentage
The amount is after adding the percentage and dividing the number of months

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

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

Example:
Percantage = 5%
Price = 100,000
Months = 5

Percentage x Months = 5 * 5% = 25%
Price * 25% = 25,000
25,000 + 100,000 = 125,000
125,000 / 5 = 31,250
