How AffordEMI works out what you can afford in the United States
Two numbers drive everything on this page: the payment formula lenders use, and the share of your income they will let that payment take. For the United States the conservative ceiling is 36% of net monthly income across all your obligations, and a stretched approval reaches 45%. The default rate is 7.3% a year on vehicle finance and 9.5% on two-wheelers, which are market averages rather than an offer to you.
The formula
EMI = P × r × (1+r)ⁿ ÷ ((1+r)ⁿ − 1), where P is the amount financed after your down payment, r is the annual rate divided by twelve, and n is the term in months. Reducing balance, monthly rest, no balloon and no final lump sum — every instalment shown clears the debt in full by the end of the term.
Why 36% and not more
Your existing commitments come out first, so what remains is genuinely available rather than theoretical. The dashed mark on the meter sits at 20% of income, which is where most planners put the vehicle on its own, because fuel, insurance, servicing and parking are never inside the instalment. The gap between that dashed mark and the 36% line is the difference between what a lender will approve and what leaves you room to live.
Questions people ask about car finance in the United States
What is the 20/4/10 rule?
Put 20% down, finance for no more than 4 years, and keep total vehicle costs — payment, insurance, fuel, maintenance — under 10% of gross income. It is stricter than what lenders will approve, which is the point. This calculator shows both: the dashed mark on the meter sits at 20% of take-home for the payment alone, while the safe zone reflects the 36% debt-to-income ceiling lenders actually underwrite to.
Does the sticker price include tax?
No. MSRP excludes sales tax, title, registration and destination or dealer fees. Sales tax alone runs from zero in Oregon to roughly 9% in California and Illinois once local rates are added. Pick your state and the calculator loads that on top before it computes the payment, because you finance the out-the-door number, not the window sticker.
How much does my credit score change the payment?
A lot. Super-prime borrowers see new-car APRs in the mid single digits while subprime rates can run three or four times higher, and the same car becomes a completely different monthly number. The default here is a market average. If you have a preapproval letter, switch the rate to "Set my own" and enter your actual APR — a preapproval from your own bank or credit union is also the strongest negotiating position you can walk into a dealership with.
Should I lease instead?
A lease usually shows a lower monthly payment for the same car because you are paying for depreciation over the term rather than buying the vehicle. You end with nothing and mileage caps apply. This tool models purchase financing only — a fully amortizing loan with no balloon — so treat the numbers as the buy case and compare a lease quote against them separately.
Where the prices come from
MSRP before sales tax, title and registration for popular variants on sale now, curated by hand rather than scraped live. Sales tax runs from nothing in Oregon to roughly 9% in California and Illinois once local rates are added. Prices move constantly — treat every figure here as a starting point and confirm with the dealer before you commit to anything.
