Prompt-to-cost estimation
Paste a prompt and the calculator estimates its token count, then prices that prompt across the models shown in the table.
Token Counter
ReclamarToken Counter is a free web app for estimating LLM API costs, counting tokens, and comparing pricing across hundreds of models.
Overview
Token Counter is a web-based LLM pricing calculator and token counter for estimating API usage costs across a large set of models. The homepage says it supports GPT-5, Claude, Gemini, Llama, DeepSeek, and 300+ LLM models, with one interface for counting tokens and comparing prices across providers.
The main workflow is simple: paste a prompt or enter usage in tokens, words, characters, or API calls, then review the resulting cost estimates in the model table. The page also notes that token counts use the OpenAI cl100k tokenizer as a reference, so counts are approximate and may differ slightly by model.
Core features
Multiple input modes
Switch between token counts, words, characters, and API calls to model different ways of estimating usage.
Cross-model price comparison
Compare input and output pricing for GPT-5, Claude, Gemini, Llama, DeepSeek, and many other models in one view.
Pricing table by model
Shows a model table with input cost, output cost, and estimated tokens so you can scan pricing differences quickly.
Reference-based token counting
Uses the OpenAI cl100k tokenizer as a reference and notes that actual counts may vary slightly by model.
Updated pricing snapshot
Surfaces a last-updated timestamp for the pricing view, which helps readers understand when the displayed rates were refreshed.
Common use cases
Pre-flight API budgeting
Estimate the cost of a prompt before sending it to multiple LLMs so you can choose a model based on price rather than guesswork.
Model comparison
Compare how the same text prices across GPT-5, Claude, Gemini, Llama, DeepSeek, and other models when you are evaluating options.
Prompt optimization
Check token usage and projected cost while drafting or editing prompts to keep requests smaller and easier to control.
Usage conversion
Use the calculator to translate usage in words, characters, or API calls into a model-specific cost estimate.
Pricing research
Review the pricing table as a quick reference when you need a current snapshot of input and output pricing across many models.
Pros and Cons
Pros
- Covers a wide model set, including GPT-5, Claude, Gemini, Llama, DeepSeek, and many more.
- Supports several ways to estimate usage, including prompt text, tokens, words, characters, and API calls.
- Shows input and output cost side by side in a model comparison table.
- Provides a single place to compare pricing across providers without switching between vendor pages.
Cons
- Token counts are approximate because the calculator uses the OpenAI cl100k tokenizer as a reference.
- The source does not document advanced setup, team features, or external integrations beyond the web interface.
FAQ
What does Token Counter do?
It is a web-based calculator and token counter for estimating LLM API costs from prompts, token counts, words, or characters.
Which models can it compare?
The page states that it supports GPT-5, Claude, Gemini, Llama, DeepSeek, and 300+ models. It compares pricing across providers in one place.
How do you estimate cost with it?
The page notes a prompt-based workflow where you paste text and the tool counts tokens and prices it across models below. It also offers input modes for tokens, words, characters, and API calls.
How accurate are the token counts?
The page says token counting uses the OpenAI cl100k tokenizer as a reference, and that actual counts vary slightly by model.
Is it designed for teams?
The source does not show team, account, or admin features, so usage should be treated as individual web-tool access unless more documentation is provided.
