anyone know how to use the ba II plus calculator?? im trying to figure out interest..

[Ender510]

here's my example and what i know..

for N, I put in 360 (30 years)
for I, i put in 6 for (6% annual)
for PV, i put in 200000 (for 200,000 total)
then i hit CPT PMT

This gives me the value:
$1199.10

This includes both interest and pricipal. How do i find out what the interest is only? thanks
