Loan = Price − Down Payment If rate=0: Monthly = Loan / Months If rate>0: EMI = Loan × r × (1+r)^n / ((1+r)^n − 1) where r = annual rate / 12 / 100

Example Calculation

Inputs

Product Price (PKR): 50000 PKR
Down Payment (PKR): 10000 PKR
Installment Period: 12 months
Annual Interest Rate (0 for interest-free): 20 %

Suppose you enter: Product Price (PKR) = 50000, Down Payment (PKR) = 10000, Installment Period = 12, Annual Interest Rate (0 for interest-free) = 20. The calculator applies the formula (Loan = Price − Down Payment\nIf rate=0: Monthly = Loan / Months\nIf rate>0: EMI = Loan × r × (1+r)^n / ((1+r)^n − 1)\nwhere r = annual rate / 12 / 100) and shows all output values below.
