BizPhoton publishes the math behind common legal situations, state by state and county by county: injury settlement estimates built from the multiplier and per-diem methods described in published consumer-legal literature, each state’s comparative-negligence rule, damage caps and filing deadlines, child support guideline formulas (income shares, percentage of income, and Melson) run step by step, spousal-support formulas where a state publishes one and its statutory factors where it does not, custody schedule planning with overnight counts, will execution requirements — witnesses, notarization, holographic and electronic wills — cited to the probate code, and property tax appeal math with county protest deadlines. Every changing figure is transcribed from its own source: state legislatures and judiciaries, state child support agencies, state revenue departments, and county assessors, each with a visible verification date and a link back to the document. Estimates are ranges, never single numbers, and every calculation runs entirely in your browser.

bizphoton.com publishes calculators and verified government figures for education and planning. It is not tax, legal, accounting, or financial advice, and using this site does not create a professional relationship. Every changing figure links the official source it came from. For advice about your own business, consult a licensed professional in your state. Full disclaimer
The interface is available in six languages. Statutory text, guideline formulas and court rules stay in the language their source published them in — a translated statute is an unverified statute, and every figure here links the document it came from.
🤖 AI-readable: every figure here is open JSON, and every calculator answers AI assistants through our MCP server — disclaimer and source URL attached to each response.
