Cost Day

Editorial standards

The route a post takes from first draft to your screen.

Wording last reviewed

  1. Sources come first

    Every post lists the pages it leans on, such as manuals, agency pages and the help pages of estimating tools. A claim with nothing behind it stays out.

  2. Write, trace, check

    Each post is written by an AI tool. Code traces every figure to a listed page, and a checker model from another AI maker reads the figures once before publishing.

  3. Examples are examples

    Where a post works a sum, the numbers are invented and the post says so. CostDay quotes no average markup, because no one figure suits every job.

  4. Not a price for your job

    A post explains a method. It is not an estimate for your project, a bid bond, a stamp or a professional opinion. Your own takeoff and your own rates decide your own price.

  5. Dates

    A post carries two dates: when it went live, and when its figures were last traced.
