Token Calculatorv1.0.0

Use the Token Calculator to convert between tokens, words, characters, and pages, and use the Text Analysis Tool to measure a real text sample. Set the encoder and pricing to estimate AI token costs, model input limits, and reading or speaking time before you send content to a language model.

Convert common text units to tokens and compute cost in a few steps.

• Select an Encoder to set the words-per-token ratio used for conversions.
• Click Swap Unit and choose Tokens, Words, Characters, or Pages as your input.
• Enter your value in Number of Tokens or in the selected unit.
• Set Words per page to match your page estimate convention for reports or manuscripts.
• Choose a Currency and enter Cost per token or restore the encoder default.
• Review Tokens, Words, Characters, Pages, and Cost as the tool updates results in real time.
• Toggle Show Facts to compare length against familiar benchmarks such as short story or novel scale.

Analyze a precise text sample to plan prompt size and budget.

• Paste or type text into the textarea to calculate token count, word count, and character totals.
• Review page count, estimated reading time, and speaking time to plan scripts, podcasts, and videos.
• Adjust Encoder and Words per page to align estimates with your workflow and style guide.

Understand how the token counter and cost estimator derive results. Ratios are approximate and vary by encoder.

• Words per token = encoder ratio (default 0.75 words per token).
• Words = Tokens × words per token.
• Tokens = Words ÷ words per token.
• Characters ≈ Words × average characters per word (default 5).
• Pages = Words ÷ words per page (default 500).
• Estimated cost = Tokens × cost per token, displayed with your selected currency.
• Reading time (minutes) ≈ Words ÷ 250.
• Speaking time (minutes) ≈ Words ÷ 130.

Apply this token calculator to plan prompts, manage API budgets, and size content for AI models, writing, and research.

• Estimate AI usage cost by converting planned prompts and completions to tokens and currency.
• Check model input limits by converting large documents to token counts before submission.
• Plan article, essay, or script length by comparing words, pages, and reading or speaking time.
• Scope proposals, theses, and reports by translating target pages into words and tokens.
• Measure dataset size for training or evaluation by converting bulk text to tokens and pages.
• Run cost scenarios by switching encoders, adjusting words per page, and updating cost per token.
• Prepare retrieval and question answering content by keeping passages within token limits.

Plan a blog post by entering 1,200 words and reviewing the token count, page estimate, and reading time to fit your publication template. Price a customer support summary by pasting the draft and checking the token cost against your monthly budget. Validate a dataset by converting a 50-page report to tokens to confirm the content fits within a model context window. Compare encoders by switching the Encoder and observing changes to cost per token and total spend. Align a video script by checking speaking time to target a 3-minute, 5-minute, or 10-minute slot.

What is a token? A token is a unit of text that a language model reads or writes. The ratio of words to tokens varies by encoder. Why do costs differ? Providers price input and output tokens differently and may change rates over time, so treat the calculator as a planning tool. How accurate are page counts? Page counts depend on your words-per-page setting. Set this value to match your formatting. How should I use encoders? Use the encoder that matches your target model to improve token estimates. Can I use currencies other than USD? Yes. Select a symbol and enter your price per token, then review cost in your chosen currency.
