LiuNengAI Subscription Cost Calculator

A free, no-login browser calculator for comparing two subscription quotes in Chinese yuan (CNY). Enter each quote and choose monthly or annual billing, then see the monthly equivalent, a twelve-month cost estimate, and the cost per actual usage day. It does not fetch live prices or exchange rates, and it does not compare product features. Annual comparisons assume twelve continuous months at unchanged prices. Calculations run locally; entries are not uploaded. The English standalone page has no analytics or external JavaScript, and a single-file offline version and source are available on GitHub. Built with AI assistance and operated by LiuNengAI, an independent business with separate paid services. This calculator is free to use independently; LiuNengAI is not affiliated with OpenAI.
