About the project

Make the estimate useful, then make it honest.

Deficit Compass is a free calorie-planning utility built to turn a maintenance estimate into a usable starting plan without hiding the math or uncertainty.

Why it exists

Most calorie calculators stop at a maintenance number or present a deficit with false precision. Deficit Compass starts with a published equation, exposes alternative estimates, lets the user choose a body-weight-relative pace, checks a goal date, and encourages calibration from actual intake and weight trends.

The calculator runs without an account. The basic planning tools will remain free.

Who built it

Deficit Compass was built by and is the property of Builderfox LLC. The company developed an internal calorie-planning workflow into this public web utility and is responsible for the software, methodology documentation, and correction process.

Builderfox LLC does not present itself as a physician or registered dietitian. The methodology cites primary research and government guidance, but the site has not yet received formal medical review. That limitation is stated wherever it matters rather than replaced with an invented credential.

Corrections and partnerships

Formula errors, accessibility issues, source corrections, and responsible partnership proposals are welcome through Contact. Material changes are recorded in the correction log.

Advertising and commercial relationships are disclosed clearly. They do not change calculator results and are not presented as medical endorsements. Read the editorial policy for the complete standard.
