Definitions

Mortgage amount

Original balance of your mortgage.

Interest rate

Annual interest rate for your mortgage. Interest rates are generally lower for shorter-term mortgages. Please note that the interest rate is different from the Annual Percentage Rate (APR), which includes other expenses such as mortgage insurance, and the origination fee and or point(s), which were paid when the mortgage was first originated. The APR is normally higher than the simple interest rate.

Marginal tax rate

This is your combined state and federal tax rate. This is used to calculate possible income tax savings by deducting your mortgage interest. Please consult with a tax professional regarding mortgage interest deductions and your specific situation. Use the ‘Filing Status and Federal Income Tax Rates on Taxable Income’ table to assist you in estimating your federal tax rate.
