I have searched the net and formated the function like all the examples but
the payment is way out of line.

In cell L57 I have the annual interest rate, in M57 the numbers of years for
the loan and K57 is the principal.

=PMT(L57/M57*12,M57*12,-K57)

The principal is $714,136.63 the rate is 8% and the terms is 7 years but it
returns a paymetns of $9,793,873.81. This is what it should be from the
online calculators I've used $14,480.11.

What am I doing wrong?
