New money in, new car out. The raise is monthly, the car is monthly, so the test is monthly.
The test: new money in, new car out
A raise or a new job changes take-home pay. This page works in take-home pay directly: the money that lands in the account each month. No gross pay, no tax rates, no tax advice. The test is simple: the raise each month, minus the car each month, is what the raise leaves behind. If that number is negative, the car eats the whole raise and dips into the old budget. If it is positive, the raise covers the car and leaves something over.
The example car, priced per month
The car is the 2026 Hyundai Elantra SE from the site's Elantra door: $23,870, 35 miles per gallon, 12,000 miles a year, gas at $4.071 a gallon, the EIA national average, week ending August 31, 2026, insurance at $2,255 a year, maintenance and repairs at $452 a year, and a payment of $487.73 a month on $24,054 financed at 8% APR over 60 months. Turned into monthly figures, each rounded to the cent:
| Monthly cost | Amount |
|---|---|
| Payment | $487.73 |
| Insurance ($2,255 a year divided by 12) | $187.92 |
| Fuel (12,000 miles divided by 35 mpg times $4.071, divided by 12) | $116.31 |
| Maintenance ($452 a year divided by 12) | $37.67 |
| All-in monthly cost | $829.63 |
The sum: $487.73 plus $187.92 plus $116.31 plus $37.67 equals $829.63 a month. That is the number the test runs against.
Formula
The car is the 2026 Hyundai Elantra SE from the site Elantra door: $23,870, 35 miles per gallon, 12,000 miles a year, gas at $4.071 a gallon, the EIA national average, week ending August 31, 2026, insurance at $2,255 a year, maintenance and repairs at $452 a year, and a payment of $487.73 a month on $24,054 financed at 8% APR over 60 months. Turned into monthly figures, each rounded to the cent: payment $487.73, insurance $187.92 ($2,255 a year divided by 12), fuel $116.31 (12,000 miles divided by 35 mpg times $4.071, divided by 12), and maintenance $37.67 ($452 a year divided by 12). The sum is $487.73 plus $187.92 plus $116.31 plus $37.67, which equals $829.63 a month.
The test is the raise each month minus the car each month. With an $800-a-month raise on the old $4,000 take-home pay, the raise is $800 a month, or $9,600 a year, and the car is $829.63 a month, or $9,955.56 a year. The raise falls $29.63 a month short, which is $355.56 a year, so $800 minus $829.63 is minus $29.63 a month. After the car, $3,970.37 is left for everything else, against $4,000 before the raise, so the household ends up $29.63 a month tighter. With a $1,000-a-month raise, or $12,000 a year, the raise covers the car and leaves $170.37 a month, or $2,044.44 a year: $1,000 minus $829.63 is plus $170.37, and $5,000 minus $829.63 leaves $4,170.37, which is $170.37 a month more than the old $4,000.
The break-even raise is the car itself: $829.63 a month, or $9,955.56 a year. A raise smaller than that cannot cover this car on its own. A raise bigger than that covers it and leaves the difference. That break-even line belongs to this car only: a cheaper car needs a smaller raise, and a pricier car needs a bigger one. Monthly figures are rounded to the cent, then summed, so the table adds exactly.
Two raises, same car
Same car, same old paycheck of $4,000 of take-home pay a month. Only the raise changes.
| Old take-home | New take-home | Raise | Car | Raise left | Left for everything else | Compared with before |
|---|---|---|---|---|---|---|
| $4,000 | $4,800 | +$800.00 | $829.63 | -$29.63 | $3,970.37 | $29.63 tighter |
| $4,000 | $5,000 | +$1,000.00 | $829.63 | +$170.37 | $4,170.37 | $170.37 better |
Read the first row all the way through. The raise is $800 a month, or $9,600 a year. The car is $829.63 a month, or $9,955.56 a year. The raise falls $29.63 a month short, which is $355.56 a year. After the car, $3,970.37 is left for everything else, against $4,000 before the raise. The raise happened, and the household still ends up $29.63 a month tighter.
Read the second row the same way. The raise is $1,000 a month, or $12,000 a year. It covers the car and leaves $170.37 a month, or $2,044.44 a year. After the car, $4,170.37 is left for everything else, which is $170.37 a month more than the old $4,000.
The raise the car needs
The break-even raise is the car itself: $829.63 a month, or $9,955.56 a year. A raise smaller than that cannot cover this car on its own. A raise bigger than that covers it and leaves the difference. That break-even line belongs to this car only. A cheaper car needs a smaller raise, and a pricier car needs a bigger one, which is what the calculator is for.
What this page leaves out
Taxes and deductions. This page starts from take-home pay, so it never converts gross pay. A gross raise looks bigger than the take-home raise. Run the test on the take-home figure.
The car's loss in value. Depreciation is a real cost over 5 years, but it is not a monthly cash payment, so it is not in the monthly test here.
Parking and tolls. Both are real monthly costs in many cities, but they sit outside the Elantra all-in figure used here, so add them to your own total if you pay them.
Job-change extras. A new commute, a new parking bill, a benefits change. None are modeled here. They move the test in either direction.
How this page differs
The 15% test page checks a car against 15% of take-home pay, a budget rule. The how much car can I afford page works out how much car fits a budget. This page is the raise itself: new money in against new car out, at a job change or a raise. For your own raise, car, loan, and quote, the calculator is where every input above gets replaced.

Definitions
Take-home pay. The money that lands in the account each month. This page works in take-home pay directly: no gross pay, no tax rates, no tax advice.
Raise left. The raise each month minus the car each month. If that number is negative, the car eats the whole raise and dips into the old budget. If it is positive, the raise covers the car and leaves something over.
Break-even raise. The raise that exactly covers the car. On this page, $829.63 a month, or $9,955.56 a year.
All-in monthly cost. Payment plus insurance plus fuel plus maintenance. On this page, $829.63 a month.
Depreciation. The car loss in value. A real cost over 5 years, but not a monthly cash payment, so it is not in the monthly test here.
APR. Annual percentage rate, the yearly interest rate on the loan. This example uses 8%. For context, Experian reported average rates of 6.35% on new cars and 11.19% on used cars in the second quarter of 2026.
Questions people actually ask
Should I buy a car when I get a raise?
Run the monthly test. On the example on this page, an $800-a-month raise does not cover an $829.63-a-month car: it leaves you $29.63 a month tighter than before the raise. A $1,000-a-month raise does cover it, with $170.37 a month to spare. That is the comparison, not a verdict: your raise, your car, and your quotes move every figure.
How much of a raise do I need to afford a car?
At least what the car costs each month. On the example Elantra at $829.63 a month, the break-even raise is $829.63 a month, or $9,955.56 a year. A smaller raise cannot cover that car on its own; a bigger raise covers it and leaves the difference.
Does a raise cover a car payment?
Only if the raise is bigger than the whole monthly cost, not just the payment. On the example, the payment alone is $487.73 a month, but the all-in cost with insurance, fuel, and maintenance is $829.63 a month. An $800-a-month raise covers the payment and still falls $29.63 a month short of the whole car.
What happens to my other spending after a raise and a new car?
It moves by the difference between the raise and the car. On the example, a $4,800 take-home pay minus the $829.63 car leaves $3,970.37 for everything else, which is $29.63 a month less than the old $4,000. At $5,000 of take-home pay, $4,170.37 is left, which is $170.37 a month more than before.
How is this different from the 15% test page?
The 15% test page checks a car against 15% of take-home pay, a budget rule. The afford page works out how much car fits a budget. This page is the raise itself: new money in against new car out, at a job change or a raise. The calculator is where your own numbers replace the example.
