AI Token Cost Calculator
Token cost equals input tokens × input rate ÷ one million plus output tokens × output rate ÷ one million. Enter the rates for your actual provider and processing tier.
Formula & method
Total = input tokens × input price / 1,000,000 + output tokens × output price / 1,000,000.Worked example
| Input | Value |
|---|---|
| Billable input tokens | 2,000 |
| Billable output tokens | 500 |
| Input rate per million tokens | 3 ¤ |
| Output rate per million tokens | 9 ¤ |
| Result | Value |
|---|---|
| Input token cost | 0.006 ¤ |
| Output token cost | 0.0045 ¤ |
| Combined token cost | 0.0105 ¤ |
Compare scenarios
The first input changes while the other example inputs stay fixed. These are arithmetic scenarios, not forecasts.
| Compare scenarios | Billable input tokens | Input token cost | Output token cost | Combined token cost |
|---|---|---|---|---|
| −20% | 1,600 | 0.0048 ¤ | 0.0045 ¤ | 0.0093 ¤ |
| Example | 2,000 | 0.006 ¤ | 0.0045 ¤ | 0.0105 ¤ |
| +20% | 2,400 | 0.0072 ¤ | 0.0045 ¤ | 0.0117 ¤ |
Assumptions & limits
Example rates are arbitrary inputs, not current prices for any model. Check whether reasoning, cache reads, cache writes, image/audio tokens, tools, regional processing or tier changes are billed separately. Use recorded billable usage when available.
Displayed results are rounded. Calculations use unrounded JavaScript numbers; small floating-point differences are possible.

Cached Input Cost Calculator
Mixed input cost equals cached tokens at the cache-read rate plus remaining tokens at the uncached rate. A cache hit fraction is an input assumption, not a guaranteed provider behavior.
AI Request Budget Calculator
Affordable whole requests equal budget divided by estimated per-request token cost, rounded down. The calculation assumes the same average input and output usage for each request.
Context Window Budget Calculator
Remaining context equals the supplied context limit minus instruction tokens, history tokens and output reserve. Count all relevant prompt material using your provider’s tokenization rules.
Token Generation Time Calculator
For positive output length, estimated time equals first-token latency plus the remaining token count divided by the generation rate. Zero requested tokens gives zero modeled generation time.
