1. What is the Edmunds Affordability Formula?

The Edmunds Affordability Formula helps determine how much you can comfortably spend on a car payment based on your income, existing debts, and debt-to-income (DTI) ratio limits.

2. How Does the Calculator Work?

The calculator uses the Edmunds Affordability Formula:

Where:

• \( Income \) — Your monthly gross income (USD)
• \( Debts \) — Your monthly debt obligations (USD)
• \( DTI\ Limit \) — Recommended debt-to-income ratio (typically 0.36)

Explanation: The formula calculates what portion of your income (after accounting for existing debts) should be allocated to a car payment while maintaining a healthy DTI ratio.

3. Importance of DTI Calculation

Details: Maintaining a proper DTI ratio (typically below 36%) is crucial for financial health and loan approval. Lenders use DTI to assess your ability to manage monthly payments.

4. Using the Calculator

Tips: Enter your monthly income, monthly debt obligations, and desired DTI limit (0.36 is typical). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a good DTI limit?
A: Most lenders recommend keeping your total DTI below 36%, with no more than 15-20% going toward car payments.

Q2: Should I use gross or net income?
A: This calculator uses gross income (before taxes), which is what lenders typically consider.

Q3: What debts should I include?
A: Include all monthly debt obligations: credit cards, student loans, personal loans, and existing car payments.

Q4: Does this include insurance and maintenance?
A: No, this calculates just the car payment. Budget separately for insurance, fuel, and maintenance.

Q5: How does down payment affect affordability?
A: A larger down payment reduces your needed loan amount, which may allow for a more expensive car within the same payment range.
