    that wouldn't be too tough.

    you'll need about 6 variables.

    and the pow function in cmath as Stoned_Coder said will also be needed.

    attempt 1 but not working

    loanamount = loanmopayment * (1 - pow((1 + loanrate), -loanterm)) / loanrate;

    you also need to think about placement of loanamount and loanmopayment. i'm assuming loanmopayment is the monthly payment and loanamount is the principle.
