I come up with \$228.26 per month(principal and interest).

## PV=\$9,000 I/Y=10 N=48

\$228.26

Buy a financial calculator and check these links out:

I just found this site two days ago… and I have read just about every article I have found… You Guys are great… But I’m still confused about how you calculate the monthly payments on a property… let’s say that you have a property that sells for \$10,000 … with \$1,000 down for 48 months at 10% int… what would the monthly payment be with the interest… and how do you go about making the actual calculation…

Thanks for your time

Formula to Calculate Monthly Payment - Posted by Dave T

Posted by Dave T on February 09, 2000 at 22:45:48:

Monthly PMT = LoanAmount/((1-(1/(1+rate)^n))/rate)

Where rate is the monthly interest rate (divide the annual rate by 12) and n is the number of payment periods. The ^ means that the term (1+rate) is raised to the power of n.

While you don’t necessarily need a financial calculator to compute the monthly payment amount, you will at least need a calculator capable of raising a number to a power to use this formula.

Get an Amortization Booklet, available at any bookstore for a few bucks. You can look up payments at any amount, interest rate and term instantly. Financial calculators will do the same thing.

In excel
=PMT(annual % rate/12,#months,-principal)

From there you could also do an amortization table.
