What this may mean for you
The payment is only part of ownership: insurance, fuel, and maintenance typically add hundreds per month. A common guideline keeps ALL vehicle costs near 15–20% of take-home pay — so treat this ceiling as a maximum, and notice how much it drops at a shorter term (that's the interest you wouldn't pay).

Understanding this calculator
Dealers negotiate on payment because payments hide price. Flip the script: decide the monthly amount that fits your budget first, then walk in knowing the exact price ceiling it supports — taxes, fees, trade-in, and down payment included. That single number changes the entire conversation.
A common guideline holds total vehicle costs — payment, insurance, fuel, maintenance — near 15–20% of take-home pay. The payment is only part of that, so leave headroom below whatever this calculator returns.
Assumptions and methodology
- The maximum loan is the present value of your target payment over the chosen term at the quoted APR.
- Price is solved from the loan by backing out sales tax (applied to price minus trade-in, the rule in most states), financed fees, down payment, and trade-in value.
- Insurance, registration, fuel, and maintenance are not included — budget them separately.

Common questions
Longer term = more car. Why not take it?
An 84-month term raises your price ceiling but keeps you underwater on a depreciating asset for years and adds thousands in interest. Guideline worth knowing: if the car only works at the longest term, it's more car than budget.
