How do I calculate prepayment penalites?

Answer 1

Usually a prepayment penalty is 6 mos. interest on 80% of your balance. So calculate 80% of your balance times 1/2 of your
interest rate.

100000 balance @ 80% = 80,000
6.5 % rate @ 1/2 = 3.25
80,000 x 3.25% =2600

Answer 2

How can we tell you how to calculate if you don't tell us what your prepayment penalty is? Is it 1, 2, or 3%? Is it 6 month's interest?
