AI Assistant Cost Calculator: tokens, server, subscriptions - By DzheiGuide

What does a self-hosted AI assistant in a messenger really cost? Tokens, not the server, are the main expense — and without a calculation it is easy to overpay threefold. This calculator works out your monthly spend: server, model tokens with prompt caching, gateways and extra services, plus your own support hours. It shows the cost of one dialogue and one message, compares against team subscriptions and tells you at which volume the assistant becomes cheaper than a subscription.

What´s inside. An interactive HTML calculator (one file, offline) in 4 languages (Russian, English, Chinese, Kazakh) and 5 currencies. Separate fields for input, output and cached token prices, cache share, exchange rate, and load (dialogues per day, messages per dialogue, tokens per message). Results: monthly cost, first month including setup, cost per dialogue and per message, the break-even volume in dialogues, setup payback and the revenue needed for the assistant to pay off after tax.

Who it´s for. Anyone launching an AI assistant or an AI-powered bot; anyone deciding between team subscriptions and their own infrastructure; developers who need to explain the price of a solution to a client.

Example. 30 dialogues a day with 6 messages each, 1200 input and 300 output tokens per message, 60% cache, a model at $0.3 per million input tokens: tokens cost 227 RUB a month, server and gateways 990 RUB, six support hours 4 800 RUB — 6 017 RUB a month and 7 RUB per dialogue. Subscriptions for two employees cost 4 000 RUB, so the calculator immediately shows the overpayment and suggests what to cut: context, caching or hours.

How it works. One HTML file in any browser, no internet. Rates are editable and saved in the browser, with a reset-to-example button and a built-in guide on where to get the numbers: bot analytics, token usage reports, the model provider´s pricing page.
