How accurate are they?

Our civil litigation calculators use up-to-date statutory rates, provincial and state data, and the same formulas lawyers and courts rely on. They are designed for planning and research — actual outcomes depend on your specific facts, jurisdiction, and judicial or agency discretion. Rates are reviewed and updated as laws change. For decisions that matter, confirm the numbers with a licensed lawyer.

Canada and United States coverage

Legal rules differ sharply between the two countries, so every civil litigation calculator is built in a Canadian version (using provincial rules) and a US version (using state-level rules). You are viewing the Canada edition; switch countries any time from the calculator hub.
