| Approach | Car payment | Max car price | All-in monthly |
|---|---|---|---|
| Conservative (10% of income) | $250 | $16,476 | $600 |
| Moderate (15%) | $550 | $31,448 | $900 |
| Aggressive (20%) | $850 | $46,420 | $1,200 |
Keeping all-in car costs near 15% of your $6,000 monthly income leaves about $550 for the loan payment after $350 of insurance, fuel and maintenance. With $4,000 down at 7.50% over 60 months, that supports a car around $31,448. The table shows a cautious and an aggressive figure on either side.
A widely used guideline: put at least 20% down, finance for no more than 4 years, and keep total car costs under 10% of gross income. It's deliberately conservative — it keeps you out of negative equity and leaves room for the rest of life. Your current down payment is 13% of the moderate target, and this car would run about 15% of your income all-in.
Once you have a target price, the auto loan calculator shows the exact payment, interest and total cost for a real vehicle — including sales tax, fees and any trade-in.

Auto loan calculatorThe price on the windshield is only part of what a car costs you each month. The real budget question includes the loan payment, insurance, fuel, maintenance and repairs — together often 50–60% more than the payment alone. A car you can technically finance can still wreck a budget once those running costs are added.
This calculator works backwards from your income and existing debts to a price that fits everything, not just the payment. It shows three levels — conservative, moderate and aggressive — because affordability is a range, not a single line, and where you sit in it depends on how much flexibility you want elsewhere in your life.
Two guardrails keep car buyers out of trouble. The 20/4/10 rule says: put at least 20% down, finance for no more than 4 years, and keep total car costs under 10% of gross income. It's conservative on purpose — following it almost guarantees you stay above water on the loan.
The second is debt-to-income: lenders and planners want your total monthly debt payments, including the new car, under about 36% of gross income. If existing debt already uses much of that room, it — not the income rule — becomes the real limit on what you can afford, which is exactly what this calculator flags.
Depreciation is the largest and most ignored cost of a car. A new car loses roughly 20% of its value in the first year and around 60% over five, most of it early. Buying a two-to-three-year-old car lets someone else absorb that steepest drop, which is why a used car often delivers far more value per dollar.
Paying cash, where feasible, eliminates interest entirely and forces the budget to be honest — you can only buy what you actually have. Financing isn't wrong, especially at a promotional rate, but the affordability math should start from total cost of ownership, not from the monthly payment a dealer can always massage lower by stretching the term.
Insurance, fuel and maintenance add 50–60% on top of the payment. A car that fits the payment but not the all-in cost still breaks the budget.
A car payment stacks on top of current debt. If total debt exceeds ~36% of income, the budget is stretched regardless of what the income rule alone suggests.
A 72- or 84-month loan lowers the payment but signals the car is too expensive, and keeps you underwater for years.
Little or nothing down means starting underwater and paying interest on the full price. Aim for 10–20% down.
A new car's value drops fastest in the first years. Buying slightly used captures most of the value for far less money.
A common guideline keeps all-in car costs — payment, insurance, fuel and maintenance — under about 15% of gross income, with total debt including the car under 36%. On a $6,000 monthly income that's roughly a $30,000–35,000 car with a moderate down payment, though existing debt can lower it. Enter your numbers above for a personalized range.
It's a conservative affordability guideline: put at least 20% down, finance for no more than 4 years (48 months), and keep total monthly car costs under 10% of your gross income. Following it keeps you out of negative equity and ensures the car doesn't crowd out other financial goals.
On the total cost of ownership, not the payment. Dealers can lower almost any payment by stretching the loan term, which hides a higher price and more interest. Start from what total monthly cost fits your budget, then work back to a price and term — which is exactly what this calculator does.
Yes, significantly. Lenders and planners cap total monthly debt payments — including the new car — at around 36% of gross income. If student loans, credit cards or another car already use much of that room, your safe car budget shrinks accordingly. Paying down existing debt first raises what you can afford and often improves your rate.
The traditional benchmark is 20% down on a new car and 10% on a used one. A larger down payment lowers your loan, reduces interest, cuts the monthly payment, and protects you from negative equity in the early years when the car depreciates fastest.
Used usually wins on value. A new car loses about 20% of its value in the first year, so a two-to-three-year-old car lets someone else absorb the steepest depreciation while you get most of the useful life. That said, low promotional financing and full warranties can occasionally make a new car competitive — run both through the numbers.
