The formula for calculating the mortgage-to-value ratio is that the mortgage-to-value ratio is equal to the amount of the loan/the total amount of the house payment. For a mortgage loan, the buyer uses the property rights of the purchased house as collateral, and the bank pays the house price to the developer first. In the future, the house buyer will pay the principal and interest to the bank in monthly installments. The bank mortgage percentage usually ranges from 50% to 80%.

What is the calculation method for mortgage loan repayment?

1. Equal principal and interest repayment method: monthly monthly payment = [loan principal × monthly interest rate × (1 + monthly interest rate )^number of repayment months〕÷〔(1+monthly interest rate)^number of repayment months-1〕, monthly interest payable=loan principal×monthly interest rate×〔(1+monthly interest rate)^number of repayment months- (1+monthly interest rate)^(repayment month serial number-1)〕÷〔(1+monthly interest rate)^number of repayment months-1], monthly principal payable = loan principal × monthly interest rate × (1+ Monthly interest rate)^(repayment month serial number-1)÷[(1+monthly interest rate)^number of repayment months-1], total interest = number of repayment months×monthly payment amount-loan principal.

2. Equal principal repayment method: monthly monthly payment = (loan principal ÷ number of repayment months) + (loan principal - cumulative amount of repaid principal) × monthly interest rate, each Monthly principal repayment = loan principal ÷ number of repayment months, monthly interest repayment = remaining principal × monthly interest rate = (loan principal - cumulative amount of repaid principal) × monthly interest rate, monthly monthly payment reduction amount = Monthly principal payable × monthly interest rate = loan principal ÷ number of repayment months × monthly interest rate, total interest = (total loan amount ÷ number of repayment months + total loan amount × monthly interest rate) + total loan amount ÷ repayment Number of months of payment × (1 + monthly interest rate)] ÷ 2 × number of months of payment - total loan amount.
