Frequently Asked Questions
How much should I spend on a car?▾
Financial advisors recommend keeping total vehicle costs (payment + insurance + gas + maintenance) under 15-20% of take-home pay. On a $5,000/month take-home, that is $750-1,000/month total — not just the car payment. Use our Car Affordability Calculator for a personalized recommendation.
Is leasing or buying better?▾
Buying is almost always cheaper long-term. Leasing makes sense if you want a new car every 2-3 years, drive under 12,000 miles/year, and value lower monthly payments over ownership. Use the Lease vs Buy Calculator to compare total costs for your specific situation.
