Editorial Independence & How Content Is Produced

Content on SmallBizCalc is compiled by our editorial team from official source data. Raw data from IRS, SEC, FDIC, NCUA, and related financial agencies is transformed into readable profiles by our continuous editorial pipeline, then validated against the source before publication. The SmallBizCalc editorial team, operating under Kiznis Studio, is responsible for editorial standards, methodology, and corrections.

We do not accept payment, sponsorship, or promoted placement from financial firms, banks, advisors, or any covered entity. Our only revenue source is contextual display advertising served by Google AdSense — advertisers do not influence which entities we cover or how we present data, and they do not receive preferential placement.

Our Approach

Every calculator on SmallBizCalc is designed for speed and privacy. Computations run entirely in your browser — your financial data never leaves your device. Formulas follow standard accounting and business finance methodologies, and each calculator includes an explanation of the underlying math so you understand the result, not just the number.

We test each calculator against real-world scenarios and edge cases before publishing. Where industry-specific nuances affect the calculation — like variable tax rates or seasonal adjustments — we document the assumptions clearly. The tools are free to use with no signup, no account creation, and no data collection.
