About this app

Don't let the dealership do the math for you.

Walk in prepared. Car Payments Calculator gives you the tools to estimate monthly

payments, total interest, and true costs — before you ever sit down with a dealer.

Free to use. Run unlimited loan and lease calculations, use every calculator, and

keep your numbers — no account, no sign-up, no trial.

WHY PEOPLE SWITCH FROM A PLAIN LOAN CALCULATOR

Most calculators only do loans. A lease is different math, and it's where dealers

make the most margin. This app does both, properly:

• Money factor — the lease version of an interest rate, and the number most

shoppers never get shown. Enter it as MF or as APR; we convert either way.

• Residual value — in dollars or as a percent of MSRP

• Cap cost reduction — see exactly what your down payment is buying you

• Trade-in equity — including when you still owe more than it's worth…

Five-star share of ratings
65–79% five-star
Arithmetic on the stores' own published rating counts. It says nothing about why the ratings fall where they do.

In the app package we scanned

No package has been scanned for this app, so nothing is published about what it ships. That is an absence of evidence, not a finding.

Method and limits

What this report can and cannot show

What a missing label means

Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.

Limits of this report

  • A package scan is static. It identifies code and text in one Android build. It does not measure a live ad session, test a deletion request, or count the steps needed to cancel.
  • Reviews keep their sample. A review-only charge shows distinct reviewers, the share and the sample size, and is published only once it clears that label’s published threshold. Calibration labels are machine-drafted and not yet confirmed by a person.
  • Not assessed is a state. It is never a zero and never a pass.
  • A missing label is not a clean bill of health. It means the evidence did not support one, not that the app is problem-free.
Not yet human-reviewed. A human review gives an app hands-on, recorded measurements. None has been run for this app. Hands-on inspections are not yet open.
