About & methodology

AI Calc is an independent collection of 45 free calculators, with English and Chinese interfaces and income-tax models for 10 countries. No account is required.

Transparent calculations

Each tool shows its formula and assumptions. Tax models link to official sources and identify the tax year and supported scope. They are not complete tax-filing software.

Loan models

Level payments, equal principal, extra principal payments and Canadian semiannual compounding are supported. We do not provide live lender quotes or determine eligibility. Taxes, insurance and early-repayment charges require separate consideration.

Quality & updates

Core formulas and edge cases are checked with automated tests. Testing does not guarantee error-free results. Use official tools for circumstances outside the stated scope. Rules were reviewed on 19 October 2026; subsequent policy changes require review.

Independent brand

AI Calc is not affiliated with Calculator.net and does not use its branding or proprietary code. This version does not cover all of that website’s approximately 200 calculators.
