TypicalCosts publishes what things cost, with the source attached.
The problem we are trying to fix
Most "average cost" pages on the web are written by someone who has no idea what anything costs. They contain a number with no publisher, no date and no method, and it is frequently wrong by a factor of two. That is not a reference; it is a guess with a heading.
What we do instead
We take figures that an authority actually published — a Bureau of Labor Statistics average price series, a Statistics Canada consumer price index, a Freddie Mac mortgage survey, an IRS mileage rate — and we reproduce them with the publisher, the reference period and a link to the original. Every row in every table on this site carries those four things: publisher, source URL, as-of date and retrieval date.
Where no authority publishes a figure, we do not estimate one. The page says so and shows the sources instead. That means some pages carry no number at all. We think a page that admits this is worth more than a page that invents a figure.
What we are not
We are not a lender, a broker, a contractor, an insurer, a law firm or a medical provider. We do not quote jobs. We do not make credit decisions. Some links are affiliate links and we disclose them next to the link, every time.
How the site is built
Every page is rendered from a database, so a correction is a data change rather than a rewrite. Prices are published per row, so a page shows what it has and says what it lacks.
