Cars depreciate faster than the loan amortises in the early years, so a long term on a small deposit can leave you owing more than the car is worth. Shorter terms cost more monthly but avoid that.
How it works
The calculation runs in your browser as you type — there is no submit button and nothing is sent anywhere. Change any figure and the results update immediately, which makes it easy to see how sensitive the answer is to each input.
Every formula used here is standard and documented in the questions below. Where a result depends on an assumption, the assumption is stated rather than buried.
Frequently asked questions
What term should I choose?
Shorter is cheaper overall. A 7-year car loan has a tempting monthly payment but you will pay far more interest and spend years in negative equity.
Does this include tax, title and fees?
No. Enter the amount you are actually financing, which normally includes those costs if you rolled them into the loan.
Is dealer financing worse than a bank?
Not always — manufacturer promotional rates can beat banks. Compare the total repaid figure, not the monthly payment, since dealers often stretch the term to make payments look smaller.
Is this calculator free?
Yes, with no account, no limits and no data collection. It runs entirely in your browser.
Should I rely on this for a financial or medical decision?
No. It is a planning estimate built on standard formulas and stated assumptions. For decisions that matter, speak to a qualified professional who can account for your full circumstances.
Is this calculator accurate?
The arithmetic is exact — it uses the standard formula, shown in the questions above. What limits accuracy is the assumptions: the figures you enter, and factors the formula does not model such as fees, taxes and rule changes. Treat the result as a well-founded estimate rather than a quotation.
Do I need to sign up or download anything?
No. It runs in your browser, updates as you type, and stores nothing. There is no account, no download, and no limit on how many times you use it.
