Paste text → see what it costs across every model
Quick token count + dollar estimate before you send a prompt. Pick your content type for accuracy.
Paste any text and see exactly how many tokens it becomes across major tokenizers (GPT, Claude, Gemini). Cost projection at the current model catalog included.
- Words ≠ tokens — same text tokenizes 10-20% differently across vendors, breaking naive cost estimates
- Avoid the classic budget-blowup: thinking 1 word = 1 token, then discovering 1.3× actual
- Pre-flight prompt size before you commit to a model with a tight context window
- Calibrate cost-calculator inputs with real numbers instead of guesses
These are the inputs, outputs, and how you can use this calculator for your AI workloads.
- Content typeTunes char-per-token expectation
- Sample textThe text to tokenize
- Expected output tokensResponse size estimate
- Input token countTokens for the pasted text
- Chars per token ratioDensity of your text
- Cost across modelsWhat this text costs per call
Stop guessing — paste real samples, get exact counts
Plug actual numbers into Cost Calculator instead of placeholder guesses
See if your prompt is bigger than expected before it hits production
Verify your prompt + retrieval + history fits in your chosen model's context window
👇 Now try the calculator below with your own AI workloads
Prompt, document chunk, or any content you'd send to an AI API.
Enter text to see per-request cost ranked cheapest first.
| Model | Per request | Per 1K requests | Per 1M requests |
|---|---|---|---|
| Paste some text above to compare costs. | |||
- Right-size your prompts — trim what's wasteful, keep what matters
- Pick the cheapest tokenizer — the per-vendor table is ranked cheapest-first for your exact text
- Project it to scale — per-request × your volume = the real monthly bill
What this means + what to do next
- Per-call retry overhead (typically 3-15% on top of base token cost)
- Conversation history accumulation in multi-turn workloads
- System-prompt overhead repeated on every call (often 200-1000 tokens you're paying for forever)
- Output bloat — verbose models cost more than the input estimate suggests
- Get the actual $/month at the token counts you measured here Cost Calculator
- For multi-turn workloads, this single-call count vastly underestimates total agent cost Agent Loop Cost
- If your token count is bigger than expected, often 20-40% is reducible without quality loss Token Reduction Analyzer
This is a measurement tool — ROI conversations happen downstream:
- Is my prompt 30% bigger than it needs to be? (Run reduction analysis.)
- How much of my token budget is overhead vs unique input per call?
- Would a smaller model handle this prompt with acceptable quality?
- Quantify savings from compression, context-window-pruning, structured output Token Reduction Analyzer
- If your prompt has a stable prefix, caching can cut effective cost 50-80% Prompt Cache Roi
- If some queries are simpler than others, routing cuts cost without quality loss Multi Model Router
If you don't have sample text yet, these calcs work from estimates:
- You can estimate token shape from memory (typical chat ~1500 in, ~500 out) Cost Calculator
- You're planning multiple apps without specific prompts yet Budget Planner
- You want to see how this cost grows at 10× and 100× volume Scale Projection
