LexScale.ai hosts 400+ free legal calculators across 23 practice areas, and every single one is built in both a Canadian and a United States version — no other legal-calculator site in North America comes close on breadth or dual-country coverage. Every calculator is free, needs no signup, runs privately in your browser, and can be embedded on your own site.
Legal rules differ sharply across the border and between provinces and states, so a single "North American" calculator would be wrong for most users. Instead, every tool has a Canadian edition using provincial rules and a US edition using state-level rules — from Ontario's Construction Act to California's MICRA cap.
Our calculators use current statutory rates, provincial and state data, and the standard formulas lawyers and courts rely on. They are planning and research tools, not legal advice — outcomes depend on your facts and jurisdiction. Read how our calculators work and where the numbers come from.
