formula Payment=PV*r/(1-(1+r))^-n, r rate, and n number compoundings
\n" ); document.write( "monthly it is PV(r/12)/(1-(1+r/12)^-nt), nt will be 30
\n" ); document.write( "=12000(0.125/12)/(1-(1+(.125/12)^-30))
\n" ); document.write( "=125/(1-(1.010416667)^-30) do without rounding until the end
\n" ); document.write( "$467.81 is the monthly payment
\n" ); document.write( "30 of them is $14034.30
\n" ); document.write( "the loan was $12000
\n" ); document.write( "The interest paid is the difference of $2034.30
