Financial Decisions
Can I afford a new car right now?
Probably not the one you're looking at. The car industry is very good at making expensive things feel affordable. Monthly payment is the wrong number to focus on.
The short answer
- 1. Add up payment, insurance, fuel, and maintenance. That total should be under 15% of your take-home pay.
- 2. If a 72-month loan is needed to make the payment work, the price tag may be beyond what the income comfortably supports.
- 3. New cars lose 20%+ of value in year one. A 2–3 year old version of the same car is significantly cheaper and already depreciated.
- 4. High-interest debt and a missing emergency fund are typically worth addressing before adding a new car payment.
The real factors
The factors that tend to matter more than the monthly payment.
Monthly payment is the wrong number to look at
Dealers know that people buy on monthly payments. A 72-month loan at a high interest rate can make a $45,000 car feel affordable at $650/month. But the total cost over 6 years, including interest, might be $52,000. That car will be worth around $18,000 at the end of it. The monthly payment hides the full picture on purpose. Look at total cost of ownership: purchase price, interest paid over the loan term, insurance, fuel, and expected maintenance.
Common trap
Extending the loan term to lower the payment. Going from 48 to 72 months might save $150/month but adds thousands in interest and keeps you underwater on the loan longer than the car stays reliable.
Rule of thumb
Total car costs (payment, insurance, fuel, maintenance) is commonly benchmarked at under 15% of take-home pay. Many people use 10% as a more conservative target. At 20%+, the car may be stretching the budget significantly.
New cars lose value fast
A new car loses roughly 20% of its value the moment you drive it off the lot, and another 10% in the first year. By year five, most cars are worth less than half what you paid. That's not a reason to never buy new, but it is a reason to think carefully about how long you plan to keep it. If you're trading in every 3 years, you're consistently paying the steepest part of the depreciation curve.
Common trap
Financing a depreciating asset at a high rate is one of the fastest ways to go underwater. If you owe $28,000 on a car that's now worth $19,000 and something goes wrong, you're stuck.
Rule of thumb
Plan to keep a new car at least 5–7 years to get value out of it. If you want to trade frequently, a slightly used car (1–3 years old) lets someone else absorb the worst of the depreciation.
What your current debt picture looks like matters
Adding a car payment on top of existing high-interest debt is usually a bad move. A $600/month car payment is money that isn't going toward credit cards, an emergency fund, or anything else. Think about what you're giving up by committing that amount every month for the next 4–6 years.
Common trap
Thinking of a car as a separate financial decision from everything else. It isn't. A new car payment can delay paying off debt, push back retirement contributions, and wipe out savings growth for years.
Rule of thumb
If you have high-interest debt, pay that down before taking on a car payment. If you have no emergency fund, build that first. A car is a want, most of the time. Plan for it accordingly.
Be honest about what you actually need
Most people buying a new car don't need a new car. They need reliable transportation. A 3-year-old version of the same model costs significantly less, is largely depreciated, and often still has the original warranty. The new car feeling fades. The payments don't. That said, if you're driving something unreliable and repairs are eating your budget, there's a real case for upgrading.
Common trap
Justifying a new car purchase as cheaper than repairs on an old one without actually running the numbers. Unless your current car needs repairs that approach its value, keeping it is usually the cheaper path.
Rule of thumb
If your current car's annual repair costs are approaching 50% of its value, replacing it starts to make financial sense. Otherwise, keep it.

If you're carrying existing debt, see what it would take to clear it before adding a car payment. Sometimes it's shorter than you think.

Check which of these fit before deciding.
Car payment would exceed 15% of take-home pay
You'll feel this in your budget every month for years.
No emergency fund yet
A car expense or job gap will put you in a very difficult position.
Considering a 72+ month loan to make payments work
Stretching the term is a sign the purchase price doesn't fit your budget.
Can pay cash or 20%+ down with a short loan term
Short loans at lower rates minimize the interest cost.
Current car is costing more in repairs than it's worth
At that point you're spending money without building any asset.
The decision
If the total monthly cost of the car (payment, insurance, fuel, maintenance) fits comfortably under 15% of your take-home and you're not ignoring high-interest debt or an empty emergency fund to do it, you can probably afford it.
If you're stretching the loan term, skipping a down payment, or choosing a model because the payment sounds manageable, you're buying more car than your finances support right now. That's not a judgment. It's just what the numbers say.
The used car argument is genuinely strong. A 2-year-old version of almost any vehicle is 20–30% cheaper, past the steepest depreciation, and often still under warranty. If you're flexible on new vs. used, the financial case for used is hard to argue with.
The worst version of this decision: buying a car you can barely afford on a long loan with no money down, then needing to sell it two years later. You'll owe more than it's worth and have very few good options. That's the situation to avoid above all others.
