How Much Should You Actually Spend on a Car?

Determining your car budget in Wichita starts with your life, not a generic online rule. Learn how to calculate what you can comfortably afford while keeping your monthly finances in balance.

Andrew Woods October 8, 2026

Let's say you make $60,000 a year.

How much car can you afford?

$20,000?

$30,000?

$40,000?

If you Google it, you'll find plenty of rules telling you exactly how much you should spend based on your income.

There's just one problem.

Two people making $60,000 can have completely different financial lives.

One has cheap rent, no debt and plenty of savings.

The other has three kids, a mortgage, student loans, daycare and a refrigerator that has recently started making a noise that sounds expensive.

Their car budgets probably shouldn't be identical.

So instead of starting with a generic rule, I'd start with a different question:

What can you comfortably afford to own?

Quick Answer

There isn't one percentage of your income that determines how much you should spend on a car.

Your realistic budget depends on:

  • Your take-home income
  • Housing expenses
  • Existing debt
  • Insurance
  • Fuel
  • Maintenance
  • Savings
  • Down payment
  • Trade equity or negative equity
  • Interest rate
  • Loan term
  • How much financial breathing room you want every month

And there's one distinction I really want you to understand:

Being approved for a car doesn't necessarily mean you can comfortably afford it.

A lender is deciding whether it's willing to loan you the money.

You have to decide whether you actually want that obligation.

Start With Your Life, Not the Car Lot

This is where I'd begin.

Before figuring out whether you can afford a $35,000 car, look at what your money is already doing every month.

Start with your actual take-home income.

Then look at expenses like:

  • Housing
  • Utilities
  • Groceries
  • Childcare
  • Credit cards
  • Student loans
  • Medical expenses
  • Insurance
  • Subscriptions
  • Savings
  • Entertainment
  • Other debt

What's left?

More importantly:

How much of what's left are you comfortable committing to transportation?

That's a much more useful starting point than somebody on the internet announcing that every human being should spend exactly 13.7% of their income on a car.

Your Car Payment Isn't Your Car Budget

This is probably the biggest mistake people make when deciding what they can afford.

Let's say you decide:

"I can afford a $500 car payment."

Okay.

What about insurance?

Maybe that's another:

$180 per month.

Fuel?

Maybe:

$150 per month.

Maintenance and tires?

That won't necessarily hit every month, but the expense is still real.

Suddenly your $500 car is costing significantly more than $500 to own.

Your actual transportation budget needs to account for the vehicle around the payment.

Insurance Can Completely Change the Answer

Please check this before buying the car.

Especially if you're:

  • A younger driver
  • Buying a performance vehicle
  • Moving from liability-only coverage to full coverage
  • Buying a much more expensive vehicle
  • Changing from an older vehicle to a newer one

Imagine you've found the perfect car.

The payment is:

$475 per month.

Perfect.

Then you call your insurance company.

Your premium increases by:

$160 per month.

Your $475 decision just became a $635 decision before you've put a gallon of gas in it.

Get an insurance quote before you buy.

It's boring.

It's also much more fun than discovering the number afterward.

Don't Forget Fuel

If you're moving from an efficient compact car into a full-size truck or SUV, fuel costs can change substantially.

Think about:

  • How many miles you drive
  • Mostly city or highway driving
  • Fuel economy
  • Fuel type
  • Your normal driving habits

A vehicle that fits your payment budget may not fit your total budget if you're suddenly spending substantially more at the gas station.

The reverse can also happen.

A more efficient vehicle may cost slightly more to buy but save you money in fuel.

Look at the complete picture.

Maintenance Is Still a Bill Even If It Doesn't Arrive Monthly

This is especially important with used vehicles.

Maybe your payment is affordable.

Great.

But eventually you're going to need:

  • Oil changes
  • Tires
  • Brakes
  • Filters
  • Scheduled maintenance
  • Repairs

If you're buying a vehicle that requires expensive tires or specialized maintenance, budget accordingly.

Four tires on one vehicle may cost dramatically more than four tires on another.

And please don't buy a car so close to the edge of your budget that a set of tires becomes a financial emergency.

Cars need stuff.

Plan for it.

How Much Car Will the Bank Approve You For?

Potentially more than you should buy.

This is worth repeating.

A lender evaluates things such as your income, credit, existing obligations, vehicle, amount financed and overall risk.

If you're approved for a $45,000 loan, that doesn't mean someone has officially certified:

"Congratulations. Spending $45,000 on a car is a fantastic idea for your life."

It means the lender is willing to finance the transaction under its terms.

You still get to say:

"I'd rather spend $30,000."

You don't have to use every dollar somebody is willing to lend you.

Work Backward From a Comfortable Payment

I'm normally cautious about shopping entirely by monthly payment.

But your monthly budget still matters.

The trick is to use payment as a planning tool, not as the only way you evaluate the deal.

Let's say you've looked at your finances and decided:

$450 per month feels comfortable.

Not:

"I could survive $600 if I stopped going anywhere fun."

Comfortable.

Now you can work backward.

The vehicle price that produces a $450 payment depends on:

  • APR
  • Loan term
  • Down payment
  • Trade equity
  • Taxes
  • Fees
  • Amount financed

That's why asking:

"What car can I get for $450 per month?"

doesn't have one answer.

Interest Rate Makes a Huge Difference

Two people can buy the same car for the same price and have very different payments.

Suppose each finances:

$30,000 for 72 months.

At roughly 5% APR, the payment is about:

$483 per month.

At roughly 10% APR, it's about:

$556 per month.

At roughly 15% APR, it's about:

$634 per month.

Same $30,000.

Very different payments.

That's why your budget shouldn't be based solely on the advertised price of the vehicle.

You need to understand what financing actually looks like for you.

Loan Term Can Hide an Expensive Car

Here's where things get dangerous.

You want a particular vehicle.

The payment is too high.

So you extend the loan.

Suddenly:

"Hey! It fits my budget!"

Sort of.

A longer term can lower your monthly payment because you're spreading the loan across more months.

But that doesn't make the vehicle cheaper.

You may:

  • Pay more total interest
  • Stay in debt longer
  • Build equity more slowly
  • Increase the chance of being upside down if you trade early

A lower payment can absolutely help cash flow.

Just understand what you're trading to get it.

Down Payment Can Help, but Don't Empty Your Bank Account

Putting money down can reduce the amount you finance.

That's useful.

But suppose you have:

$8,000 in savings.

You put all $8,000 down to make the payment work.

Now you have:

$0 in savings.

Your transmission doesn't care.

Your furnace doesn't care.

Your employer doesn't care.

Life continues happening after you buy the car.

I'd rather see somebody choose a vehicle they can comfortably afford while maintaining reasonable emergency savings than drain everything they have just to force an expensive vehicle into their monthly budget.

Your Trade Can Change Your Budget

If you have a trade-in, find out two numbers:

What is it worth?

and

What do you owe?

Suppose your trade is worth:

$15,000

and your payoff is:

$10,000.

You have approximately:

$5,000 in positive equity.

That can reduce the amount you need to finance.

Now reverse it.

Your vehicle is worth:

$15,000

but you owe:

$20,000.

You're approximately:

$5,000 upside down.

That negative equity doesn't disappear because you're buying another vehicle.

Depending on the transaction and lender, some or all of it may need to be paid by you or included in the new financing.

That can dramatically change how much vehicle you can realistically buy.

"I Can Make the Payment" Isn't the Same as "I Can Afford It"

This distinction matters.

Maybe you technically can make a $700 payment.

Every month.

Barely.

But doing so means:

  • You stop saving
  • Credit-card balances grow
  • Unexpected expenses become emergencies
  • You can't comfortably travel or enjoy anything
  • You're constantly worried about money

Is the car affordable?

I'd argue probably not.

Affordability should include some breathing room.

A car is supposed to make your life easier.

If you're scared to check your bank account every time the payment comes out, we may have gotten a little carried away.

What About the 10%, 15% or 20% Rules?

You'll see plenty of formulas online.

Some say your car payment shouldn't exceed a certain percentage of take-home income.

Others calculate total transportation costs.

Others have rules for loan length and down payment.

I don't think those guidelines are useless.

They can give you a starting point.

I just wouldn't treat them as laws of physics.

If you take home $5,000 per month and have very low living expenses, your comfortable transportation budget may be different from someone taking home the exact same amount while supporting a family and carrying significant debt.

Your actual budget wins.

Buying Less Car Than You Can Afford Is Allowed

This might be my favorite car-buying strategy nobody gets excited about.

Suppose you could comfortably buy a $40,000 vehicle.

You find a $27,000 vehicle you love that does everything you need.

You are allowed to buy the $27,000 one.

There is no prize for maximizing your auto loan.

That extra money could:

  • Stay in savings
  • Pay down other debt
  • Go toward retirement
  • Fund travel
  • Go toward a house
  • Give you more breathing room every month

The goal isn't to determine the absolute maximum amount of car you can drag across the financial finish line.

It's to buy something that fits your life.

Sometimes Spending More Can Make Sense

On the other hand, cheapest isn't always smartest.

Suppose Vehicle A is:

$18,000

but it's older, has substantially more mileage and may need maintenance soon.

Vehicle B is:

$23,000

with lower mileage, better condition and features you'll actually use.

If you can comfortably afford either, spending another $5,000 may make sense.

Budgeting isn't about buying the cheapest possible object.

It's about making sure the additional money is buying something you actually value.

Think About How Long You'll Keep It

This matters too.

If you're buying something you expect to keep for eight or ten years, paying more to get exactly what you want may be easier to justify.

If you tend to replace vehicles every two years, stretching your budget becomes much riskier.

You may still owe a substantial amount when you're ready to trade.

That can create negative equity.

And negative equity has a nasty habit of following people from one vehicle to the next.

Don't Build Your Budget Around Future You

Be careful with this:

"I'll be making more money next year."

Maybe you will.

I hope you do.

But the payment starts now.

Build your budget around the income and expenses you actually have.

If your financial situation improves later, fantastic.

You can save more, pay the loan down faster or do something else with the money.

Future You will appreciate Current You not volunteering them for a payment they never agreed to.

My Favorite Affordability Test

Before buying, imagine the vehicle has been sitting in your driveway for six months.

The excitement is gone.

It's Tuesday.

You have to go to work.

It's just your car now.

Would you still be comfortable with:

The payment?

The insurance?

The fuel?

The amount you took out of savings?

The amount of debt you owe?

If the answer is yes, you're probably getting closer to a sensible budget.

If the only reason the numbers feel acceptable is because you're currently excited about the car, give yourself a little time.

Questions to Ask Yourself Before Buying

Before deciding what you can afford, ask:

What is my actual take-home income?

How much do I already spend every month?

What would the insurance cost?

How much will I spend on fuel?

Do I have money set aside for maintenance and repairs?

How much savings will I have left after my down payment?

Do I have positive or negative equity in my trade?

What APR am I realistically looking at?

How long am I comfortable financing?

Would I still feel good about this payment if an unexpected $1,000 expense happened next month?

That last question is a pretty good one.

Bottom Line

The right amount to spend on a car isn't determined by your salary alone.

It's determined by your entire financial situation.

Don't start with:

"What's the most expensive car I can get approved for?"

Start with:

"What can I comfortably own without making the rest of my life harder?"

Then account for the payment, insurance, fuel, maintenance, savings, interest rate, trade position and everything else that comes with the vehicle.

Maybe that number is $15,000.

Maybe it's $30,000.

Maybe it's $60,000.

The goal isn't to spend as little as humanly possible.

And it isn't to buy as much car as a lender will allow.

It's to buy a vehicle you like without hating the financial decision six months later.

Frequently asked

Should I follow the 20% rule for my car budget?

Generic rules like the 20% guideline don't account for your specific expenses. Use them as a rough starting point, but always base your budget on your actual take-home pay and living costs.

Why is being approved for a loan not the same as being able to afford it?

Lenders focus on risk and credit score, not your monthly quality of life. They may approve a loan amount that leaves you with no financial breathing room for your other bills.

What costs should I include beyond just the monthly loan payment?

Always factor in insurance premiums, fuel, routine maintenance, tires, and potential repairs. These extra costs can easily add hundreds of dollars to your monthly transportation total.

How does my existing trade-in affect my new car budget?

Your trade-in determines if you have positive or negative equity. If you owe more than the car is worth, that negative equity will carry over, potentially increasing your new loan amount.
