Calculate balance checkbox
To let the calculator determine your remaining balance, based on your original loan information and years remaining, check this box. To enter your own amount, leave this box unchecked.
Balance of your mortgage that will be refinanced.
Current appraised value
The current appraised value of your home.
New interest rate
The annual interest rate for the new loan.
New term in years
Number of years for your new loan.
Loan origination rate
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.
This is the number of points paid to the lender to reduce the interest rate on the mortgage. Each point costs 1% of the new loan amount.
Other closing costs
Estimate of all other closing costs for this loan. This should include filing fees, appraiser fees and any other miscellaneous fees paid.
Monthly PMI payment
Monthly cost of Private Mortgage Insurance (PMI). For loans secured with less than 20% down, PMI is estimated at 0.5% of your loan balance each year. Monthly PMI 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 PMI, your PMI payment drops to zero.
Normally PMI is required if you have less than 20% equity in your home, however for the refinance of loan guaranteed by Freddie Mac or Fannie Mae you may not be required to pay PMI if your current mortgage doesn't require it. Check with your lenders for details. Check the box 'do NOT include PMI' if this applies to your refinance.
Your current payment is the sum of principal, interest and PMI (Private Mortgage Insurance). Because refinancing does not affect your insurance or taxes, they are not included here.
Your new payment is the sum of principal, interest and PMI.
Monthly PI payment
Monthly principal and interest payment. This does not include escrows for items such as homeowner's insurance and real estate taxes.
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 PMI & interest savings
The number of months it will take for your interest and PMI savings to exceed your closing costs.
Break even total savings after-tax
The number of months it will take for your after-tax interest and PMI savings to exceed your closing costs.
Break even total savings vs. prepayment
This is the most conservative breakeven measure. It is the number of months it will take for your after-tax interest and PMI savings to exceed both your closing costs and any interest savings you would realize from prepaying your mortgage with the cost of the closing costs on your new loan.
