| From: | To: |
The Car Affordability Calculator helps determine how much you can reasonably spend on a car based on your income and existing debt. It uses the standard financial guideline that car expenses should not exceed 20% of your income after accounting for existing debt obligations.
The calculator uses the affordability formula:
Where:
Explanation: The formula calculates what portion of your income should be allocated to car payments after accounting for your current debt obligations.
Details: Calculating car affordability helps prevent overextending your finances and ensures you choose a vehicle that fits comfortably within your budget while accounting for all associated costs (loan payments, insurance, maintenance, etc.).
Tips: Enter your income (annual or monthly) and your existing monthly debt payments. Be sure to use consistent time periods (both monthly or both annual figures).
Q1: Should I use gross or net income?
A: For more accurate results, use your net (take-home) income after taxes and other deductions.
Q2: What debts should I include?
A: Include all monthly debt obligations: credit cards, student loans, personal loans, and other recurring payments.
Q3: Does this include all car-related expenses?
A: The result represents what you can afford for the total car payment. Remember to budget separately for insurance, fuel, and maintenance.
Q4: Is 20% a strict rule?
A: This is a general guideline. Your personal situation may allow for more or less depending on other financial obligations and goals.
Q5: How does this work for leasing vs. buying?
A: The calculation works similarly for both, but remember leasing often has lower monthly payments than buying the same vehicle.
