1. What is Home Loan Borrowing Power?

The home loan borrowing power calculation determines how much you can borrow based on your affordable monthly payments, interest rate, and loan term. It helps prospective home buyers understand their purchasing capacity before house hunting.

2. How Does the Calculator Work?

The calculator uses the standard loan formula:

\[ P = \frac{PMT}{r} \times \left(1 - (1 + r)^{-n}\right) \]

Where:

\( P \) — Principal loan amount (USD)
\( PMT \) — Affordable monthly payment (USD)
\( r \) — Monthly interest rate (annual rate ÷ 12)
\( n \) — Total number of payments (term in years × 12)

Explanation: The formula calculates the present value of an annuity (the loan amount) based on regular payments, interest rate, and time period.

3. Importance of Borrowing Power Calculation

Details: Understanding your borrowing power helps set realistic expectations when house hunting, ensures you don't overextend financially, and helps with budgeting for a home purchase.

4. Using the Calculator

Tips: Enter your comfortable monthly payment (typically 25-30% of your monthly income), current interest rate, and desired loan term. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What percentage of income should go to mortgage payments?
A: Financial experts typically recommend keeping housing costs below 28-30% of gross monthly income.

Q2: How does interest rate affect borrowing power?
A: Higher interest rates reduce borrowing power as more of each payment goes toward interest rather than principal.

Q3: What's the difference between borrowing power and pre-approval?
A: Borrowing power is an estimate, while pre-approval involves a lender verifying your financial information and credit history.

Q4: Are there other factors that affect how much I can borrow?
A: Yes, lenders also consider credit score, debt-to-income ratio, employment history, and down payment amount.

Q5: Should I borrow the maximum amount I qualify for?
A: Not necessarily. It's often wise to borrow less than the maximum to maintain financial flexibility for other expenses.
