1. What is the Mortgage Affordability Calculator?

The Mortgage Affordability Calculator determines the maximum home price you can afford based on your income, existing debts, interest rate, loan term, and down payment. It uses the standard 36% debt-to-income ratio guideline.

2. How Does the Calculator Work?

The calculator uses the affordability formula:

\[ \text{Affordable Price} = \left(\text{Monthly Income} \times 0.36 - \text{Other Debt}\right) \times \frac{(1 + r)^n - 1}{r \times (1 + r)^n} \times 12 - \text{Down Payment} \]

Where:

\( \text{Monthly Income} \) — Your gross monthly income
\( \text{Other Debt} \) — Monthly debt payments (credit cards, car loans, etc.)
\( r \) — Monthly interest rate (annual rate ÷ 12)
\( n \) — Loan term in months
\( \text{Down Payment} \) — Amount you can put down upfront

Explanation: The formula calculates the maximum mortgage you can afford based on your income and debts, then adds your down payment to determine the total affordable home price.

3. Importance of Affordability Calculation

Details: Calculating affordability helps prevent overborrowing and ensures you can comfortably make mortgage payments while maintaining other financial obligations.

4. Using the Calculator

Tips: Enter your gross monthly income (before taxes), all monthly debt payments, the expected interest rate, desired loan term, and available down payment. The calculator will determine your maximum affordable home price.

5. Frequently Asked Questions (FAQ)

Q1: Why use 36% debt-to-income ratio?
A: This is a common guideline lenders use, though some may allow up to 43%. Staying at 36% provides a comfortable financial cushion.

Q2: Should I include taxes and insurance?
A: This calculator focuses on principal and interest. For a complete picture, add 1-2% of home value annually for taxes and insurance.

Q3: How does down payment affect affordability?
A: Larger down payments increase your affordable price by reducing the loan amount needed.

Q4: What if I have variable income?
A: Use a conservative average of your monthly income to ensure affordability during lower-earning months.

Q5: Are there other costs to consider?
A: Yes, factor in closing costs (2-5% of home price), moving expenses, and ongoing maintenance (1% of home value annually).
