How It Works

This calculator helps you determine the maximum car price you can afford based on your desired monthly car payment. With an average new car price projected to exceed $50,000 by 2026, it's crucial to understand your purchasing power before you start shopping.

We use a standard auto loan formula to calculate the principal amount (car price) you can borrow. This formula takes into account your desired monthly payment, the estimated interest rate (average new car loan rates are expected to be around 7.5% by 2026), and the loan term.

Remember that the car's sticker price isn't your only expense; factor in sales tax, registration fees, and insurance. A common mistake is forgetting these additional costs, which can significantly impact your true affordability.

Example: Affordable Car Price

  1. 1 Input your desired monthly car payment: $550. Input your preferred loan term: 60 months. Input an estimated interest rate: 7.5%.
  2. 2 The calculator uses the present value of an annuity formula to determine the maximum principal you can afford. PV = PMT * [1 - (1 + r)^-n] / r, where PV is the present value (car price), PMT is the monthly payment, r is the monthly interest rate, and n is the total number of payments.
  3. 3 Based on your inputs, the maximum car price you can afford is approximately $27,600.
  4. 4 This $27,600 represents the vehicle's price before taxes, fees, and any down payment. Always consider these additional costs when budgeting, as they can add thousands to the total purchase price.

Frequently Asked Questions

How much car can I afford on my monthly budget?
Use the 20/4/10 rule: 20% down payment, no longer than a 4-year loan, and total car expenses under 10% of gross income. If you can budget $500/month for a payment, you can typically afford a $22,000-$25,000 vehicle with a reasonable rate and term.
What percentage of income should a car payment be?
Financial advisors recommend keeping your car payment under 10-15% of your monthly take-home pay. Total transportation costs including insurance, gas, and maintenance should stay under 20% of take-home pay.
Does a longer loan term let me afford a more expensive car?
A longer term lowers the monthly payment but increases total interest paid significantly. A 72-month loan costs thousands more in interest than a 48-month loan and you risk being underwater on the loan for years.
