current mortgage balance owed: $55,300
57 months [4 3/4 years] left on mortgage
total monthly payment $1075 [loan only]
$105 average goes to interest
$970 average goes to principal
-----------------------------------------------------------------------------------------------
You say the interest rate is annual 5%. You have $55,300.00 balance.
For your first month interest calculate 12/.05 = .004
then calculate .004 x $55,300.00 = $230.41
$230.41 is first month interest
So now you calculate
$55,300 - $230.41 = $55,069.59
The new balance is $55,069.59
For your second month interest calculate
.004 x $$55,069.59 = $220.27
$220.27 is second month interest
So now you calculate
$55,069.59 - $220.27 = $54,849.32
The new balance is $54,849.32
So you repeat this calculation.
Sorry. So you can see the interest you pay I deduct from your balance, but you have to deduct the principal you pay from the balance too. Then repeat.
