How the math works

What this calculator does

  1. 1Monthly income = annual income ÷ 12.
  2. 2Maximum housing payment = monthly income × target DTI − monthly debts.
  3. 3Subtract estimated monthly taxes and insurance to get the principal-and-interest budget.
  4. 4Convert that budget into a loan amount with the amortization formula, then add the down payment.
Loan = PI × (1 − (1+r)^−n) / r
Price ≈ Loan + down payment

Calculator questions, answered

  1. YouHow much house can I afford?
    Funnel Suite team

    A common approach starts from a debt-to-income ratio: total monthly debts including the new housing payment divided by gross monthly income. Many programs look for 36% to 43%, some allow more with strengths. This calculator turns that into an estimated price.

  2. YouWhat DTI should I use?
    Funnel Suite team

    36% is conservative; 43% is a common upper guideline; some programs go higher. A loan officer can tell you what applies to your situation.

  3. YouDoes this include closing costs?
    Funnel Suite team

    No. Closing costs are separate from the down payment and vary by loan and location.

  4. YouWhy is my estimate different from a pre-approval?
    Funnel Suite team

    A pre-approval reviews your credit, income documents, assets and the specific program. This calculator uses only the numbers you enter.

  5. YouShould I borrow the maximum?
    Funnel Suite team

    Not necessarily. The calculator shows a ceiling under the DTI you choose; a comfortable budget depends on savings goals and other costs of owning a home.

  6. YouWhat counts as monthly debts?
    Funnel Suite team

    Minimum payments on car loans, student loans, credit cards, personal loans and other obligations that appear on a credit report, plus support payments.

  7. YouHow do lenders treat student loans?
    Funnel Suite team

    Rules vary by program, especially for deferred or income-driven plans. Ask a loan officer.

  8. YouIs this an offer of credit?
    Funnel Suite team

    No. It is an educational estimate from a website provider, not a lender.
