## Mortgage APR Calculator with Prepayments Definitions

Mortgage amount
Original or expected balance for your mortgage.
Term in years
The number of years over which you will repay this loan. The most common mortgage terms are 15 years and 30 years.
Interest rate
Annual fixed interest rate for this mortgage.
Monthly payment (PI)
Monthly principal and interest payment (PI).
Monthly payment (PITI)
Monthly payment including principal, interest, homeowners insurance and property taxes.
Annual property taxes
The annual amount you expect to pay in property taxes. This amount is divided by 12 to determine the monthly property tax included in PITI.
Annual home insurance
The annual amount you expect to pay in homeowners insurance. This amount is divided by 12 to determine the monthly home owners insurance included in PITI.
Loan origination percent
The percent of your loan charged as a loan origination fee. For example, a 1% fee on a \$120,000 loan would cost \$1,200.
Discount points
Total number of "points" purchased to reduce your mortgage's interest rate. Each 'point' costs 1% of your loan amount. As long as the points paid are not a broker's commission, they are considered tax deductible in the year that they were paid.
Other fees
Any other fees that should be included in the APR calculation. These fees can vary by lender, but at a minimum usually includes prepaid interest.
Annual Percentage Rate (APR)
A standard calculation used by lenders. It is designed to help borrowers compare different loan options. For example, a loan with a lower stated interest rate may be a bad value if its fees are too high. Likewise, a loan with a higher stated rate with very low fees could be an exceptional value. APR calculations incorporate these fees into a single rate. You can then compare loans with different fees, rates or different terms.
Total payments
Total of all monthly payments over the full term of the mortgage. This total payment amount assumes that there are no prepayments of principal.
Total interest
Total of all interest paid over the full term of the mortgage. This total interest amount assumes that there are no prepayments of principal.
Prepayment type
The frequency of prepayment. The options are none, monthly, yearly and one-time payment.
Prepayment amount
Amount that will be prepaid on your mortgage. This amount will be applied to the mortgage principal balance, based on the prepayment type.
