What you can afford
How the number is built: your monthly car payment at your APR and term sets the amount financed, and car price = amount financed ÷ (1 − down payment %). Insurance, fuel, maintenance, and registration/12 are added to the payment to show the total monthly cost of owning the car. Default: $430 payment → about a $24,419 car and $800/month total (10% down, 6.5% APR, 60 months; registration $120/year).

Assumptions: $430.00/mo car payment; insurance $150.00/mo; fuel $160.00/mo; maintenance $50.00/mo; registration $120.00/year ($10.00/mo); 10% down; 6.5% APR; 60 months. Total monthly cost $800.00.
How it works: enter what you can put toward the car payment each month after insurance, fuel, and other costs. We turn that payment into a loan amount at your APR and term, then add your down payment to get the car price. Insurance, fuel, maintenance, and registration ÷ 12 are added to the payment to show the total monthly cost of owning the car. Registration is yearly because that is how most U.S. states bill it. Price a specific car on the auto loan calculator, or compare terms in 60 vs 72 vs 84 month car loans.
Most people answer this question backward. They pick a car they want, then figure out how to afford it. That's how you end up with a $600/month payment and no emergency fund.
The right way? Start with what you can actually spend. There's a simple rule for this: 20/4/10.
How Much Car Can I Afford by Salary? (Quick Table)
If you just want the number, here is what the 20/4/10 rule produces at common salary levels: all car costs capped at 10% of gross monthly pay, $100 insurance plus $50 gas taken out first, and the rest used as the car payment on a 48-month loan at 6.5% APR with 20% down. Take-home assumes about 25% in taxes. Your exact result depends on your insurance quote, rate, and debts, so run your own numbers in the calculator above.
| Gross Salary | Est. Take-Home | Max All-In Car Cost ($/mo) | Car Payment ($/mo) | Car Price* | 20% Down |
|---|---|---|---|---|---|
| $35,000 | ~$2,190/mo | $291.67 | $141.67 | ~$7,500 | ~$1,500 |
| $40,000 | ~$2,500/mo | $333.33 | $183.33 | ~$9,700 | ~$1,900 |
| $50,000 | ~$3,125/mo | $416.67 | $266.67 | ~$14,100 | ~$2,800 |
| $60,000 | ~$3,750/mo | $500.00 | $350.00 | ~$18,400 | ~$3,700 |
| $75,000 | ~$4,690/mo | $625.00 | $475.00 | ~$25,000 | ~$5,000 |
| $100,000 | ~$6,250/mo | $833.33 | $683.33 | ~$36,000 | ~$7,200 |
| $120,000 | ~$7,500/mo | $1,000.00 | $850.00 | ~$44,800 | ~$9,000 |
| $150,000 | ~$9,375/mo | $1,250.00 | $1,100.00 | ~$58,000 | ~$11,600 |
*Car price = loan ÷ 0.80, where loan = payment × (1 − (1 + r)−48) ÷ r and r = 6.5% ÷ 12. Example at $60,000: $500 − $150 = $350 payment, which finances $14,758.62, so the car price is $18,448.28 with $3,689.66 down. Treat the price as out-the-door, including tax, title, and fees.
Notice how fast the budget shrinks at lower salaries. At $35,000, the 10% cap is about $292 a month, and after $150 of insurance and gas only about $142 is left for the payment, which buys roughly a $7,500 car. That is the 20/4/10 rule doing its job: it protects you from a payment that crowds out savings, rent increases, or an emergency.
The 20/4/10 Rule Explained
- 20% — Put at least 20% down. This keeps you from going "underwater" on your loan.
- 4 years — Finance for no more than 48 months. Longer terms hide a bad deal.
- 10% — Total car costs (payment + insurance + gas) should be under 10% of gross monthly income.
Why 20% Down Matters
Cars lose 20-30% of their value in the first year. If you put $0 down, you immediately owe more than the car is worth. If you need to sell or total the car, you're stuck paying the difference.
A $30,000 car with $0 down and 7% interest over 72 months is about $511 a month and $36,826 total. After two years you still owe about $21,359, while the car may be worth only about $21,000. Owing more than the car is worth is being underwater.
Why 48 Months Max
Short answer: keep a car loan at 48 months or less. A longer term lowers the payment but costs more interest. On a $30,000 loan at 6.5% APR, 48 months is $711.45/month with $4,149.53 total interest. Stretching to 72 months drops the payment to $504.30/month but raises total interest to $6,309.45, which is $2,159.92 more. See the full 60 vs 72 vs 84 month car loan comparison.
Dealers love pushing 72- and 84-month loans because the monthly payment looks affordable. But here's what they don't advertise:
- You pay way more interest over the life of the loan
- You're making payments on a car that's out of warranty
- By month 60, you're paying for a 5-year-old car like it's new
The 10% Income Rule in Practice
If you make $60,000/year ($5,000/month gross), your total car costs shouldn't exceed $500/month. That includes payment, insurance, and gas, not just the loan payment.
Here's a realistic breakdown for someone making $5,000/month:
| Car payment | $350 |
| Insurance | $100 |
| Gas | $50 |
| Total | $500 |
Worked Example: $50,000 Salary, Step by Step
Here is the calculator's math done by hand, so you can see exactly where the number comes from. A common ceiling for all car costs is 15–20% of take-home pay. This example uses the top of that range.
- Gross pay: $50,000 ÷ 12 = $4,166.67/month. Take-home at about 75% = $3,125.00.
- Total car budget at 20% of take-home (payment plus every ownership cost): $3,125.00 × 0.20 = $625.00/month.
- Ownership costs (the calculator defaults): insurance $150 + fuel $160 + maintenance $50 + registration $120/year ÷ 12 = $10. Total $370.00/month.
- Car payment you can afford: $625.00 − $370.00 = $255.00/month. This is the number you enter in the calculator.
- Loan amount at 6.5% APR for 60 months, using r = 0.065 ÷ 12 and n = 60: $255 × (1 − (1 + r)−60) ÷ r = $13,032.71.
- Car price with 10% down: $13,032.71 ÷ 0.90 = $14,480.79 ($1,448.08 down).
Check: plugging $13,032.71 back into M = P × r ÷ (1 − (1 + r)−n) gives $255.00 a month. Type $255 into the car payment field above (keep the default costs, 10% down, 6.5% APR, and 60 months) and you get the same $14,480.79 car, with a total monthly cost of $625.00.
Worked Example: $75,000 Salary
Same steps: $75,000 ÷ 12 = $6,250.00 gross, about $4,687.50 take-home. 20% of that is a $937.50 total car budget. Take out the same $370 of ownership costs and you can put $567.50 toward the payment. At 6.5% APR for 60 months that finances $29,004.18, and with 10% down the car price is $32,226.86 (about $3,222.69 down). Reverse check: $29,004.18 at 6.5% for 60 months is $567.50 a month. Type $567.50 into the car payment field above and the calculator shows the same $32,226.86 car and a $937.50 total monthly cost.
These are ceilings, not targets. The stricter 20/4/10 rule below (20% down, 48 months) lands lower: about $14,056 on $50k and $25,037 on $75k. The $60k walkthrough is worked in full above, including where the stricter 20/4/10 rule lands.
Worked Example: $60,000 Salary
Same steps one more time, because $60k is the question everyone actually asks. $60,000 ÷ 12 = $5,000.00 gross, about $3,750.00 take-home. 20% of that is a $750.00 total car budget. Take out the same $370 of ownership costs and you can put $380.00 toward the payment. At 6.5% APR for 60 months that finances $19,421.30, and with 10% down the car price is $21,579.22 (about $2,157.92 down). Reverse check: $19,421.30 at 6.5% for 60 months is $380.00 a month.
Where the 20/4/10 rule lands at $60k: the 10% cap is $500/month all-in — payment plus insurance plus gas. A realistic split is a $300–$350 payment, $90–$120 insurance, and $50–$80 gas. At 7% APR over 48 months, a $300 payment finances about $12,500, or roughly a $15,600 car with 20% down — the comfortable fit for most $60k households. If your insurance quote comes in high, the payment has to shrink until the three lines still add up to $500 or less.
What a $400 Monthly Payment Buys
A $400 payment at the calculator's loan assumptions (10% down, 6.5% APR, 60 months) finances $20,443.47 and buys a car priced at $22,714.97, with $2,271.50 down. Type $400 into the car payment field above to see the same $22,714.97 car. With the default ownership costs ($370/month), the total monthly cost of owning it is $770.00.
Car Price by Monthly Payment ($300 to $700)
At 10% down, 6.5% APR and 60 months, every extra $100 of monthly car payment buys about $5,678.74 more car. The last column adds this page's default ownership costs ($150 insurance + $160 fuel + $50 maintenance + $120/year registration ÷ 12 = $370/month).
| Monthly car payment | Amount financed | Down payment (10%) | Car price | Total monthly cost (payment + $370) |
|---|---|---|---|---|
| $300/mo | $15,332.60 | $1,703.62 | $17,036.23 | $670.00/mo |
| $400/mo | $20,443.47 | $2,271.50 | $22,714.97 | $770.00/mo |
| $500/mo | $25,554.34 | $2,839.37 | $28,393.71 | $870.00/mo |
| $600/mo | $30,665.21 | $3,407.25 | $34,072.45 | $970.00/mo |
| $700/mo | $35,776.08 | $3,975.12 | $39,751.20 | $1,070.00/mo |
The math: amount financed = payment × (1 − (1 + r)−60) ÷ r, where r = 6.5% ÷ 12 = 0.5417% per month. Car price = amount financed ÷ 0.90 (because 10% is down). Example: $500 × 51.1087 = $25,554.34 financed, ÷ 0.90 = $28,393.71. Type any payment into the calculator above to check it. Taxes and fees are not included.

The 20/4/10 Rule in Dollars
Put 20% down, finance no more than 4 years (48 months), and keep payment + insurance + fuel at or under 10% of gross monthly income. These examples use this page's $60,000 cost split (insurance $100 and gas $50) and a 6.5% APR.
- $60,000 salary: 10% of $5,000 gross is $500. After $100 insurance and $50 gas, the payment is $350. Car price $18,448.28 (loan $14,758.62, down $3,689.66).
- $50,000 salary: 10% of monthly gross is $416.67. Payment $266.67 (rounded to the cent). Car price $14,056.01 (loan $11,244.80, down $2,811.20).
- $75,000 salary: 10% of monthly gross is $625. Payment $475. Car price $25,036.95 (loan $20,029.56, down $5,007.39).
The calculator at the top uses 10% down and 60 months so you can compare a longer loan. To match this rule, enter the payment ($350, $266.67, or $475), set insurance to $100, fuel to $50, maintenance and registration to $0, and switch to 20% down and 48 months. The total monthly cost then reads $500.00, $416.67, or $625.00.

Bottom Line
The 20/4/10 rule isn't about deprivation — it's about not letting a car payment control your life. If the car you want breaks the rule, you have three options: save a bigger down payment, buy a cheaper car, or increase your income. There are no other doors.
