A free, privacy-first tool to help you understand exactly how much you spend on subscriptions.
SubCost is a free Subscription Cost Calculator designed to bring transparency to your digital spending. In an era where the average consumer juggles 8β12 monthly subscriptions β from Netflix and Spotify to ChatGPT, Adobe Creative Cloud, and cloud storage plans β it is easy to lose track of how much you are actually paying. SubCost solves this by letting you select the services you use from a curated database of 80+ popular subscriptions and instantly showing your daily, monthly, yearly, and 10-year spending projections with a beautiful visual breakdown.
SubCost started from a personal frustration: after cancelling an unused gym membership, we realized we had been paying for it for 14 months without noticing. That single oversight cost us over $700. We started tracking every subscription and were shocked to discover the total was nearly double what we expected. We built SubCost so that nobody else has to experience that same shock β turning a spreadsheet exercise into a beautiful, instant calculator that anyone can use in under 60 seconds.
We believe everyone deserves to know where their money goes. Subscription services have become the default business model for software, entertainment, and productivity tools β but the cumulative cost is rarely obvious. Our mission is simple: give you a clear, honest picture of your digital spending so you can make decisions that align with your values and budget.
Simply browse or search the service database, click to add the subscriptions you currently pay for, and watch your cost summary update in real time. You can edit any price to match your actual plan (family plans, student discounts, promotional rates), and you can even add custom services that are not in our database. All calculations happen locally in your browser β nothing is sent to any server.
The tool covers both international services (Netflix, Disney+, HBO Max, ChatGPT Plus, Claude Pro, GitHub Copilot, Midjourney, Spotify, and dozens more) and popular Chinese services (Bilibili, Tencent Video, iQIYI, DeepSeek, Kimi, Doubao, QQ Music, NetEase Music, WeRead, and more), making it useful for users worldwide.
We believe financial tools should never compromise your privacy. SubCost collects zero personal data. Your subscription selections are saved only in your browser's local storage, and you can clear them at any time. We do not require sign-up, login, or email verification.
SubCost is built with Next.js, React, and Recharts β modern web technologies that enable fast, responsive experiences. The entire application runs client-side, meaning your data never leaves your browser. We use no backend databases, no user accounts, and no tracking scripts beyond basic analytics.
