How our content gets written, checked, and kept current.
Last updated: July 2026
Articles on Calinsta are written to explain a specific financial or insurance concept clearly, usually tied to one of our calculators, so you can both understand the concept and immediately apply it to your own numbers.
Each calculator starts from a documented formula — either a standard financial formula (like loan amortization), a government-published figure (like IRS tax brackets or HSA limits), or, where real-world pricing varies, a clearly-labeled estimate built from published industry averages. Before publishing, we manually verify calculator output against known reference examples (for instance, checking a loan calculator's output against a published amortization table for the same inputs).
Figures tied to current law or government data — tax brackets, contribution limits, poverty guidelines, subsidy rules — are checked against primary sources (IRS revenue procedures, HHS guidelines, Congress.gov) at the time of writing or updating.
Content is reviewed for clarity and accuracy before publishing, and revisited whenever the underlying law, tax year, or government figures change.
Year-dependent figures (tax brackets, HSA limits, poverty guidelines) are reviewed at the start of each tax year at minimum. See our Changelog for a record of what's changed and when.
We rely primarily on official government sources: the IRS (tax brackets, HSA limits, revenue procedures), HHS (federal poverty guidelines, ACA rules), and published national industry data for cost estimators (insurance, in particular). Specific sources are referenced within the relevant calculator's "How this works" section where applicable.
