Editorial Policy

MotorCrunch builds tools to help people make better car-money decisions. Our calculators, guides and recommendations are produced independently of any advertiser, finance partner or affiliate. No outside party can pay to change a result, alter a default assumption or influence what we publish.

We choose what to build and what to say based on whether it genuinely helps a reader decide — not on what earns the most. If a tool or article would mislead a reader to make money, we don't ship it.

MotorCrunch is free to use. It may be supported by advertising, affiliate links or partner offers in the future. Any such revenue source is deliberately walled off from the calculation layer.

When ads are enabled, they would be served by third-party networks and never styled as part of a tool or recommendation. Any affiliate or partner offers would appear only after the math is done — and choosing to look at them would always be optional. We do not let monetization change calculator formulas or editorial guidance. The formulas, default assumptions and the result a calculator shows are identical whether or not a partner exists. Money never moves a number.

Default assumptions are based on published government or industry data where available, listed openly on our Data Sources page; where a precise public figure is not available, we use clearly labeled estimates or conservative modeled assumptions. Every calculator runs on documented, standard formulas explained in our Methodology, and every input can be replaced with your own real quote. We do not present estimates as live quotes.

Our calculator logic is written as pure, typed, unit-tested functions, so the math behaves consistently and can be verified. Assumptions are reviewed against their sources on a recurring schedule and refreshed as the data changes.

We aim to be accurate, and when we get something wrong we fix it. When a credible error is reported or found, we verify it against the source, correct the figure, formula or copy, and update any affected pages. Material corrections to published content are noted with an updated revision date.

Estimates can legitimately differ from a real quote because they depend on assumptions — that is by design, not an error. We treat genuine mistakes in our formulas, data or wording as the things to correct.

If you spot a figure that looks wrong, an outdated assumption or a mistake in our writing, please tell us. Include the page, the number you expected, and your source if you have one — it helps us check and fix it faster.

We don't invent authors, credentials, testimonials or claims that 'experts agree'. The integrity of a MotorCrunch tool comes from its math and its transparency — both of which you can inspect on every page — not from manufactured expertise. Our content is reviewed against an internal editorial standard by a team with backgrounds in consumer finance, automotive cost analysis and data modelling.
