| Term | Definition |
| Mortgage amount | Original or expected balance for this mortgage. |
| Interest rate | A periodic charge, expressed as a percentage, for the use of borrowed money. Interest rates are expressed in terms of annual rate. Please enter the annual interest rate that you currently pay on your mortgage. |
| APR | (Not requested for the purposes of this calculator). The APR (annual percentage rate) is the yearly rate of interest and other fees paid to acquire the loan. The APR calculation incorporates fees and interest into a single rate. Lenders are required by law to disclose the APR. This rate is used to compare various loans. |
| 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. |
| Monthly payment | Monthly principal and interest payment (PI). This calculation does not include taxes or insurance. You may have monthly escrow payments for these expenses. |
| 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 a one time payment. |
| Prepayment amount | Amount that will be prepaid on your mortgage. This amount will be applied to the mortgage's principal balance, based on the prepayment type. |
| Start with payment | This is the payment number that your prepayments will begin with. For a one time payment, this is the payment number that the single prepayment will be included in. All prepayments of principal are assumed to be received by your lender in time to be included in the following month's interest calculation. |
| Savings | Total "estimated" amount of interest that you save by prepaying this mortgage. |
