Token Reduction Analyzer

Paste your prompt. See what's wasteful.

Automated analysis of redundancy, verbosity, and low-value tokens. Typical prompts have 30-50% reducible tokens.

What this calculator does

Paste a prompt and see exactly which tokens are wasteful — politeness padding, redundant instructions, over-stuffed few-shot examples — and what trimming them saves at your volume.

Why use it
  • Most prompts carry 20-50% redundant tokens that add cost without improving output
  • Token reduction stacks multiplicatively with routing and caching
  • Analysis runs locally in your browser — your prompt is never sent anywhere
  • See the dollar impact at your request volume across every model

New to this calculator? Start with the ⚡ Playground — a few sliders, instant ballpark. Then switch to the 🧮 Calculator for your exact number.

Two ways to use this: visualize in the Playground, then get your number in the Calculator.

Drag the sliders to compare the two options.
Token reduction — how much could you save?

Trimming prompts, pruning context, and tightening output cut the input side of your bill. Each lever is worth roughly 12%.

💡Savings land on the input share of your bill — the bigger that share and the more levers you pull, the more optimizing wins.

📋 What now?
  • Apply the high-savings findings first — cut politeness padding, redundant instructions, and over-stuffed few-shot examples; 30-50% reduction is typical without touching quality.
  • Re-test quality after trimming — run your eval set on the leaner prompt before shipping; aggressive cuts can drop accuracy on edge cases.
  • Then cache what's left — a tight, stable prefix caches better, so prompt caching compounds the savings on top of the token cut.

Methodology

  • All prices are USD per 1 million tokens, current as of 2026-07-28.
  • Vendor-published values have no mark. Inferred/extrapolated values are marked with * and listed below.
  • Batch API discounts are 50% off standard rates across providers that offer Batch mode.
  • Prompt caching discounts vary by provider (typically 80-90% off cached input tokens).
  • Regional data-residency surcharges (Anthropic 1.1x, OpenAI 1.1x, Google regional tiers) are NOT included in base rates.
  • Long-context pricing tiers apply when input exceeds model threshold.
  • Embedding prices are input-only (no output tokens generated).
