Tokens Per Dollar Calculator

See how many tokens $1 buys on any model.

Quick answer

With the default inputs, 800,000 input tokens per $1 — 100,000 output tokens per $1 with GPT-5. Enter your own numbers below to recompute instantly; the full step-by-step math is shown under the worked example.

Flip pricing around: instead of dollars per million tokens, see how many input and output tokens you actually get for $1 (or any budget) on each model. A quick way to feel how far your money goes.

How this is calculated

For each model we invert the price: tokens per dollar = 1,000,000 ÷ price per million tokens, shown separately for input and output because output is priced higher. Enter a budget and we scale it — a $2/M input rate means $1 buys 500,000 input tokens.

Is this a good result? What to do next

This reframes pricing so cheap and expensive models feel tangible. A model that buys tens of millions of tokens per dollar is throwaway-cheap for high-volume tasks; one that buys only a few hundred thousand per dollar has to justify itself on quality.

Typical planning ranges

Budget/mini models
tens of millions of tokens per $1
Mid-tier models
~100k–300k input tokens per $1
Frontier/reasoning models
tens of thousands of output tokens per $1

Ranges are typical planning figures to sanity-check your result, not authoritative benchmarks. Your numbers will vary with use case, volume, and vendor.

How to improve this number

  • For high-volume tasks, favour models that buy the most tokens per dollar.
  • Remember output buys fewer tokens per dollar than input.

Common mistakes

  • Comparing only input tokens-per-dollar when output dominates cost.
  • Ignoring quality differences behind a big price gap.

When to use a different approach

To price a full workload rather than a budget, use the LLM API cost calculator or the model cost comparison.

Worked example (defaults)

With the default inputs above, here is the result:

  • tokens per $1 = 1,000,000 / price per 1M tokens

Frequently asked questions

How is tokens-per-dollar calculated?+

It's 1,000,000 divided by the price per million tokens. If input costs $2/M, then $1 buys 500,000 input tokens.

Why are output tokens fewer per dollar?+

Output tokens are usually priced higher than input tokens, so a dollar buys fewer of them.
