My usage is for USA only at this point.
I have inputs of loanAmount, monthlyInterestRate, numberMonths, loanFees; so
this would be for fixed monthly payments.
I understand that commonsmath doesn't have specific finance methods however
I think the APR formula is a nonlinear equation that I was hoping
commonsmath could help solve.

There are no specific finance related algorithm in commonsmath.

I think so, but it depends on what you really need. APR computation
seems to be slightly different depending on local regulations (for
example USA or EU). It also depends on the assumptions you do and the
input data. For example you can compute it one way for fixed monthly
payments and another way for varying monthly payments.
