Mortgage ÷ property value
Loan-to-value is the mortgage amount as a percentage of the property's value. It does not predict approval or the rate a lender may offer.
This calculator provides estimates only. It does not assess affordability, eligibility or whether a lender will approve a mortgage. Unless entered separately, the calculation does not include mortgage fees, insurance, taxes or other ownership costs.
Illustrative repayment scenarios only. Your actual mortgage rate may change differently.
