Example of Home Buying Budget Calculation

Let’s understand how the calculator works with a real-world example.

Scenario:

  • Annual Income: $60,000
  • Monthly Debt: $500
  • Down Payment: $20,000
  • Interest Rate: 6%
  • Loan Term: 30 years

Step-by-Step Result:

1. Monthly Income Considered (30%)
The calculator uses 30% of income as a safe housing limit:
$60,000 × 30% ÷ 12 = $1,500/month

2. Subtract Existing Debt:
$1,500 – $500 = $1,000 available for mortgage

3. Estimated Loan Amount:
Based on interest rate and term, the tool calculates a loan of approximately:
$167,000 (approx.)

4. Maximum Home Price:
Loan + Down Payment =
$167,000 + $20,000 = $187,000

5. DTI Ratio:
Around 10%–15%, which is considered financially safe.


Final Insight:

This example shows how your income and debts directly impact your home affordability. Even small changes in debt or down payment can significantly change your buying power.
