The short answer
You can afford a $500 car payment only if the complete car cost fits after your other essentials, debt payments, and protected savings. The payment is a financing number. Affordability is a household cash-flow number.
The calculator does not decide whether the car is "too expensive" in general. It shows what happens in your specific month.
Find the real monthly car cost
Start with the quoted payment, then add the costs required to keep and use the car: the insurance quote for this exact vehicle and driver, fuel or charging based on expected driving, parking, permits, and tolls, routine maintenance and tires, registration and inspection spread across the year, and a repair allowance, especially outside warranty.
Then subtract transportation costs the car will genuinely replace. If you will stop buying a train pass or using rideshares, that change belongs in the calculation. If you will keep both, it does not.
Do not let the dealer solve for the payment
A lower monthly payment can come from a larger down payment, a longer loan, or a different interest rate. Those choices change the total cost and risk even when the number on the monthly line looks comfortable.
This page is not a loan comparison tool. Before signing, also review the amount financed, annual percentage rate, loan length, and total of payments in the lender's disclosures. Here, use the monthly obligation you would actually accept and test whether your ordinary life still fits around it.
How to read your result
Fits your current plan means the real monthly car cost leaves bills and protected savings covered, with a daily amount you can live with.
Possible, but tight means the calculation stays positive but the car absorbs a large part of your flexible money. Increase insurance, fuel, and repair assumptions before deciding. Cars are especially good at producing costs that were not in the showroom conversation.
Creates a gap means the full monthly cost is greater than the money available after other commitments. The result should show how much the payment or other car costs would need to fall.
A better comparison than "Can I make the payment?"
Compare three versions: keep your current transportation, take the proposed car at the complete expected cost, and test a cheaper payment while leaving insurance, fuel, and maintenance realistic.
Look at the resulting daily number, not only the difference between sticker prices. That is the part of your life the car changes every day.
