How this calculator works

Estimate LLM API spend from token volume and per-1K pricing. Planning estimates only — verify with production tools and vendor pricing where applicable. Cost = (input tokens ÷ 1000 × input rate) + (output tokens ÷ 1000 × output rate). Example: 1M input + 200K output at $3/$15 per 1K → ~$6,000.

Cost = (input tokens ÷ 1000 × input rate) + (output tokens ÷ 1000 × output rate).

Example: 1M input + 200K output at $3/$15 per 1K → ~$6,000.

When to use this AI Token Cost Estimator

Common use cases

  • Estimate LLM API spend from token volume and per-1K pricing.
  • Sanity-check with this case: 1M input + 200K output at $3/$15 per 1K → ~$6,000.
  • The relationship is: Cost = (input tokens ÷ 1000 × input rate) + (output tokens ÷ 1000 × output rate).

Localized examples

  • Cloud Computing & AI Tech: the example on this page uses the same formula as the widget.

What you get

  • Fields: Input tokens (thousands), Output tokens (thousands), Input $/1K tokens, Output $/1K tokens
  • Cost = (input tokens ÷ 1000 × input rate) + (output tokens ÷ 1000 × output rate).
  • Example on the page: 1M input + 200K output at $3/$15 per 1K → ~$6,000.

How to Calculate AI Token Cost Estimator Step-by-Step

  1. 1Enter Input tokens (thousands), Output tokens (thousands), Input $/1K tokens, then the remaining fields. Use the values you have, not a catalog average, unless that is all you know.
  2. 2Cost = (input tokens ÷ 1000 × input rate) + (output tokens ÷ 1000 × output rate).
  3. 3Worked case: 1M input + 200K output at $3/$15 per 1K → ~$6,000.
  4. 4Compare the result to last month’s invoice or a vendor calculator before you commit capacity.

Governing formula

Cost = (input tokens ÷ 1000 × input rate) + (output tokens ÷ 1000 × output rate).

1M input + 200K output at $3/$15 per 1K → ~$6,000.

Example: set Input tokens (thousands) = 1,000, Output tokens (thousands) = 200, Input $/1K tokens = 3, then read the result.

Variable definitions

  • inputTokens

    Input tokens (thousands)

    The “Input tokens (thousands)” field. Default 1000; typical range 1–100000.

  • outputTokens

    Output tokens (thousands)

    The “Output tokens (thousands)” field. Default 200; typical range 1–100000.

  • inputRatePer1k

    Input $/1K tokens

    The “Input $/1K tokens” field. Default 3; typical range 0.01–50.

  • outputRatePer1k

    Output $/1K tokens

    The “Output $/1K tokens” field. Default 15; typical range 0.01–100.

  • Closed-form math (Cost = (input tokens ÷ 1000 × input rate) + (output tokens ÷ 1000 × output rate).) misses idle time, egress, packet loss, and reserved capacity on the real bill.
  • Nothing here is uploaded for the calculation itself.
