The formula you need to use is
\n" ); document.write( "\"PMT=PV%2Ainterest%2F%281-%281%2Binterest%29%5E%28-n%29%29\" , where
\n" ); document.write( "\"PMT\"= monthly payment,
\n" ); document.write( "\"PV\"= present value of the loan,
\n" ); document.write( "\"n\"= number of payments, and
\n" ); document.write( "\"interest\"= interest rate per pay period (as a decimal) .
\n" ); document.write( "Since they make a down payment of 20%, the loan is
\n" ); document.write( "\"%22100%25%22-%2220%25%22=%2280%25%22=0.8\" of \"%22%24330%2C000%22\" , or
\n" ); document.write( "\"PV\"\"%22=%22\"\"%22%24%22\"\"330000%2A0.8\"\"%22=%22\"\"%22%24%22\"\"264000\"
\n" ); document.write( "\"n=30%2A12=360\"
\n" ); document.write( "\"interest=%224.8%25%22%2F12=0.048%2F12=0.004\"
\n" ); document.write( "\"1%2Binterest=1%2B0.004=1.004\"
\n" ); document.write( "(rounded to the nearest 0.01).
\n" ); document.write( "
\n" );
