Who's behind this
20+ years inside banking — car loans, mortgages, credit cards, small-business lending, and now risk. I've seen the paperwork most people never get to see, and the one thing I've learned is that almost nobody explains any of it well.
I'm not a financial advisor, and nothing on this site is advice — just the math and the terms, explained the way I wish someone had explained them to me.
Now you know too.

These are estimate tools for general education — not pre-approvals, not advice, not a substitute for talking to your lender. Plug in real numbers and see real math.
Default APR is the Q2 2026 national average new-car rate (see Rates below). Use your own quote for an accurate number.
Uses the standard 28% / 36% guideline lenders commonly reference — not a pre-approval or a recommendation for what you should spend.
Works for any amortizing loan — mortgage, auto, or personal loan. Extra payment shows how much time and interest it actually saves.
| Month | Payment | Principal | Interest | Balance |

Real minimum payments usually shrink as your balance drops, so a payoff using today's flat minimum is a conservative estimate — paying only the true declining minimum would take longer.
Ran your numbers? Good.
What lenders typically ask for, by loan type — so you're not scrambling to find documents mid-application. General and publicly known; your specific lender may ask for more.
Dealer or bank financing
Purchase or refinance
New application
This is a general document checklist, not a strategy for improving your approval odds — for the step-by-step "get ready" plan, that's what the upcoming course is for.

Real, sourced figures — not made up, not rounded to sound nice. Rates move constantly, so treat these as a snapshot, not a quote.

Now you know
The words lenders use like everyone already knows them. Tap any term.
Your interest rate is the cost of borrowing the principal. APR (Annual Percentage Rate) usually adds in most lender fees, so it's the more complete number — and the one that makes it easier to compare two loans apples-to-apples.
The actual amount you borrowed, or still owe — not counting interest.
How a loan payment splits between interest and principal over time. Early payments are mostly interest; later payments are mostly principal — even though the total payment usually stays the same.
A separate account your mortgage lender uses to collect and pay your property taxes and homeowners insurance for you, usually folded into your monthly payment.
Your total monthly debt payments divided by your gross monthly income. Lenders use it to gauge how much more debt you can reasonably take on.
How much of your available credit you're using, as a percentage. $2,000 owed on a $10,000 limit is 20% utilization — one of the bigger factors in your credit score.
The smallest amount your card issuer requires each month to stay current — usually a percentage of your balance (often 1-3%) or a flat floor, whichever is higher. Paying only this keeps you in debt far longer than it looks.
MSRP is the sticker price the manufacturer suggests. Invoice price is closer to what the dealer actually paid — the real negotiating room usually sits between the two.
Pre-qualification is a quick, informal estimate based on what you self-report. Pre-approval involves an actual credit check and documentation — it carries far more weight with a seller or dealer.
The upfront amount you pay toward a purchase, reducing how much you finance. A bigger down payment usually means a smaller loan, lower payment, and less total interest.
How long you have to repay a loan. A longer term usually means a lower monthly payment but more total interest paid over the life of the loan.
A hard inquiry happens when you apply for credit and can temporarily lower your score a few points. A soft inquiry — like checking your own score — never affects it.
