The question isn't really 'what payment can I get approved for.' Lenders will often approve more than you can comfortably handle. The better question is what fits your life without making everything else tight.
The 20/4/10 guideline
- 20% down payment, so you don't owe more than the car is worth right away
- A loan of 4 years or less, so you're not paying for years after the car loses most of its value
- Total car costs (payment, insurance, gas and upkeep) under about 10% of your monthly income before taxes
It's a guideline, not a law. Plenty of people stretch one part of it. But the further you drift from it, the more a car squeezes the rest of your budget.
Example
If you earn $4,000 a month before taxes, 10% is $400 a month for everything car-related. If insurance and gas run $200, that leaves about $200 for the payment itself. That number, not the sticker price, is your real starting point.
Costs people forget
- Insurance: get a quote on the exact car before you buy. Florida's rates can be high, and they vary a lot by vehicle.
- Tax, tag, title and dealer fees on top of the price
- Maintenance, tires and repairs, especially on older or higher-mileage cars
- Gas: a bigger truck or SUV can cost much more each month than a compact car
Before you shop
Get pre-approved by your bank or credit union so you know your rate, then shop by total price, not monthly payment. A lower payment stretched over 6 or 7 years can cost thousands more in interest.
