Home equity loan amount

Original or expected balance for your mortgage. Taxpayers can deduct the interest paid on first and second mortgages up to $750,000 in mortgage debt (the limit is $500,000 if married and filing separately). Any interest paid on first or second mortgages over this amount is not tax-deductible. Starting 2018, Home equity loans will no longer qualify for a tax deduction unless they are used to buy, build or substantially improve the taxpayer's home that secures the loan. Our calculator limits your interest deduction to the interest payment that would be paid on a $750,000 mortgage.

Please note that in addition to the $750,000 mortgage debt limit, this calculator assumes that your itemized deductions will exceed the standard deduction for your income tax filing status. If your itemized deductions don't exceed your standard deduction, the benefit of deducting the interest on your home will be reduced or eliminated.
