Built to Answer One Question Honestly
Most car buying advice is written by dealerships, automakers, or financial companies with products to sell. We built CarBudgetCheck to be something different: a transparent, independent tool that gives you the math without the spin.
What We Do
CarBudgetCheck provides a free, browser-based car affordability calculator and a library of practical guides on auto financing, credit scores, leasing, and refinancing. Everything on this site is designed to help you understand the numbers before you sit down with a dealer or sign a loan agreement.
Our Editorial Approach
Every guide and calculator result on this site is based on documented financial guidelines — primarily the widely cited 20/4/10 rule and the 10–15% income rule used by personal finance advisors. We explain our methodology openly on the Methodology page so you can verify the math yourself.
We don't write sponsored content. Our guides are not written to favor any lender, automaker, or financial product. The affiliate loan offers displayed on this site are labeled clearly as such, and they have no influence over our calculator logic or editorial content.
Who We Are
CarBudgetCheck is run by a small independent team with backgrounds in personal finance content and web development. We publish under the "CarBudgetCheck Team" editorial byline, because the insights we share reflect a collective review process rather than one individual's opinion.
Affiliate Disclosure
Some links on this site — particularly in the loan offers section — are affiliate links. If you apply for a loan through one of those links, we may receive a commission from the referring lender. This commission comes from the lender, not from you, and doesn't affect the rate you're offered. See our full Disclaimer for details.
Our Data Practices
Our calculator runs entirely in your browser. We do not collect, store, or transmit any of the income, price, or payment information you enter. There is no account to create, no email required, and no data to sell. See our Privacy Policy for full details on what we do and don't collect at the site level.
Limitations and Disclaimers
This calculator produces estimates based on the inputs you provide and standard financial assumptions. It is not financial advice, and the results should not be the sole basis for a financial decision. Actual loan terms depend on your full financial profile, lender policies, and current market conditions. See our full disclaimer.
