Quality control

Data status

Last editorial review: July 26, 2026. Calculator logic, bilingual labels, internal links, and listed official-source URLs were reviewed for this release.

What changes

Program eligibility, grant availability, benefit amounts, costs, codes, product pricing, and external pages can change without notice. We link to official sources instead of promising eligibility or reproducing temporary program rules.

Cost assumptions

Cost allowances are broad U.S. planning values, not a proprietary bid database. Replace them with current local quotes before making a purchase or signing a contract.

Correction standard

When a source, label, translation, or formula materially changes, we update the affected page and its review date. A correction never guarantees that an external program or contractor is available.
