How the calculation works

Enter the required parameters and submit the form. The calculator validates the values, performs the calculation on the server and returns a detailed result.

The calculation is processed for the current HTTP request and does not require registration.

Mortgage affordability method

The model limits total monthly debt payments to the selected debt-to-income ratio, subtracts existing monthly debt, and converts the remaining payment capacity into a loan amount using the selected rate and term.

Example

The result compares several payment-to-income scenarios and combines the affordable loan amount with the available down payment and acquisition costs.

Questions and answers

Is this the amount a bank will approve?

No. It is a planning model; lenders use their own underwriting rules, income verification and stress tests.

Are existing debts included?

Yes. Existing monthly debt payments reduce the payment capacity available for the mortgage scenario.
