1. What is the FNB Car Finance Affordability Calculator?

The FNB Car Finance Affordability Calculator helps determine the maximum principal amount you can afford for a car loan based on your monthly income, expenses, debt-to-income ratio, interest rate, and loan term. This tool uses FNB's standard affordability calculation methodology.

2. How Does the Calculator Work?

The calculator uses the FNB affordability formula:

\[ P = (I \times R - E) \times \frac{(1 + r)^n - 1}{r \times (1 + r)^n} \]

Where:

\( P \) — Affordable principal amount (ZAR)
\( I \) — Monthly income (ZAR)
\( R \) — Debt-to-income ratio (decimal)
\( E \) — Monthly expenses (ZAR)
\( r \) — Monthly interest rate (decimal)
\( n \) — Loan term in months

Explanation: The formula calculates the present value of an annuity, representing the maximum loan amount you can afford based on your available monthly payment capacity.

3. Importance of Car Finance Affordability

Details: Proper affordability assessment ensures you don't overextend yourself financially and helps maintain a healthy debt-to-income ratio, which is crucial for long-term financial stability and creditworthiness.

4. Using the Calculator

Tips: Enter your gross monthly income, typical debt-to-income ratio (usually 0.3-0.4), monthly expenses, current interest rate, and desired loan term. Ensure all values are realistic and accurate for the most reliable results.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical debt-to-income ratio for car loans?
A: Most lenders recommend keeping your total debt payments (including the car loan) below 35-40% of your gross monthly income.

Q2: How do I convert annual interest rate to monthly?
A: Divide the annual percentage rate by 12. For example, 12% annual rate = 1% monthly rate (0.01 decimal).

Q3: What expenses should I include?
A: Include all regular monthly expenses: rent/mortgage, utilities, groceries, existing loan payments, insurance, and other fixed obligations.

Q4: Is this calculation accurate for all car loans?
A: This provides a good estimate, but final approval depends on credit score, employment history, and lender-specific criteria.

Q5: Should I include my partner's income?
A: Only include income that will be used for the car payment. If applying jointly, include both incomes; if individually, use only your income.
