- This is the percentage of the new mortgage that is paid to the lender as the loan origination fee. Typically this fee is 1% of the loan balance.

- Current payment
- Your current payment is the sum of principal, interest and LMI ( Loan Mortgage Insurance). Because refinancing does not affect your insurance or taxes, they are not included here.
- New payment
- Your new payment is the sum of principal, interest and LMI.
- Monthly LMI payment
- Monthly cost of Loan Mortgage Insurance (LMI). For loans secured with less than 20% down, LMI is estimated at 0.5% of your loan balance each year. Monthly LMI is calculated by multiplying your starting loan balance by this percent and dividing by 12. When the equity in your home exceeds the percentage required for LMI, your LMI payment drops to zero.
- Monthly PI payment
- Monthly principal and interest payment.
- Break even monthly payment savings
- The number of months it will take for your monthly payment reduction to be greater than closing costs.
- Break even LMI & interest savings
- The number of months it will take for your interest and LMI savings to exceed your closing costs.
- Break even total savings vs. prepayment
- This is the most conservative break even measure. It is the number of months it will take for your after-tax interest and LMI savings to exceed both your closing costs and any interest savings from prepaying your mortgage. The prepayment amount used in this calculation is the amount that you would have to spend on closing costs.
