How much car fits inside 10–15% of your take-home?
All-in car cost — payment, insurance, gas, maintenance — should land around 10–15% of your net monthly income. Here's the price that math allows.

Your payment, year by year
This is your amortization — how each payment splits between interest and paying down what you owe. Early payments go mostly to interest; later payments go mostly toward what you borrowed. Shorter loans pay off the balance faster but cost more each month.

How we compute this
Why 10–15%, and what's in "all-in".
Car cost = monthly payment + insurance + gas + maintenance/repairs. The 10–15% cap keeps total auto cost from crowding out housing, savings, and the rest.
Max for all car costs = take-home pay × 12.5%
Max loan payment = that amount − $200 (typical insurance + gas)Insurance + gas typically runs $200/mo for an average U.S. driver (the default this calculator assumes). Subtract that from your roughly 12.5%-of-take-home limit (the midpoint of the 10–15% range) to see what's left for the actual loan payment. Then solve for the max price given your rate and term.
