I have inputs of loanAmount, monthlyInterestRate, numberMonths, loanFees;

goes up, it is calculating about 4.7% and then gets
higher as loanExpenses go up (but it stays low).

There are closed-form expressions for that, although I don't have them
off the top of my head. Something like
m = P / (1 - i)^n
or maybe
m = P / ((1 + i)^n - 1)
where m is monthly paymen

There are no specific finance related algorithm in commons-math.
