Reduce Claude Token Costs with Clean Input

Every token you send to Claude's API costs money. Formatting your input as clean Markdown before sending it can cut your token usage -- and your bill -- dramatically.

Anthropic's Claude models price input and output tokens separately. When you paste raw PDFs, HTML, or unstructured text, you're paying for thousands of formatting artifacts that add zero value to the model's understanding. Clean Markdown input means fewer tokens, lower costs, and better responses.

Token Cost Comparison

Real-world example: a 10-page technical document sent to Claude in different formats.

At scale, these savings compound fast. A team processing 100 documents per day saves hundreds of dollars monthly just by formatting input properly.

Why Markdown Is Token-Efficient

• Minimal syntax overhead -- headings use #, lists use -, no closing tags or attributes
• No layout metadata -- zero bytes wasted on fonts, margins, or page dimensions
• Tokenizer-friendly -- Markdown maps cleanly to BPE tokens with minimal fragmentation
• Semantic clarity -- structure is explicit, reducing the model's parsing overhead
