Mortgage Advanced Calculators
Last updated: October 2026
Mortgage Refinance Calculator
Compare your current mortgage with a refinance: the change in monthly payment, how many months the closing costs take to recover, and the total cost difference over the life of both loans.
Mortgage Points Calculator
Determine how much your monthly payment drops when you buy discount points and calculate how long you must keep the loan to break even on the upfront cost.
Bi-Weekly Mortgage Payment Calculator
Calculate how much interest you save and how many years you cut from your mortgage by switching to bi-weekly payments.
PMI Removal Calculator
Find out when your loan-to-value ratio will drop below 80% (or 78% for automatic cancellation) so you can stop paying private mortgage insurance.
Mortgage Recast Calculator
See how a lump-sum principal payment followed by a recast (re-amortization) lowers your monthly mortgage payment at the same rate and remaining term, and how much interest it saves.
Mortgage Interest Tax Deduction Calculator
Estimate your annual tax savings from deducting mortgage interest on your federal and state returns.
Construction-to-Permanent Loan Calculator
Calculate total financing costs for building a home, including interest-only payments during construction and the permanent mortgage payment after conversion.
HELOC Payment Calculator
Calculate how your HELOC payment will jump when the draw period ends and full principal-plus-interest repayment begins, especially if rates are expected to change.
