1. What is a Low Credit Score Mortgage Calculator?

Definition: This calculator estimates monthly mortgage payments with an adjusted interest rate for borrowers with low credit scores.

Purpose: It helps potential homebuyers understand how their credit score affects mortgage payments by applying a rate adjustment.

2. How Does the Calculator Work?

The calculator uses the standard mortgage formula with an adjusted rate:

Where:

• \( M \) — Monthly payment ($)
• \( P \) — Loan principal ($)
• \( r \) — Monthly interest rate (adjusted annual rate ÷ 12)
• \( n \) — Total number of payments (term in years × 12)

Explanation: The calculator adds a credit score adjustment to the base interest rate before calculating the monthly payment.

3. Importance of Credit Score in Mortgages

Details: Lower credit scores typically result in higher interest rates, significantly impacting monthly payments and total loan cost.

4. Using the Calculator

Tips: Enter the loan amount, base interest rate, loan term, and credit score adjustment (default 1.5%). All values must be ≥ 0.
