Kingy AI decision tool
AI Workload Cost Calculator
Estimate monthly inference, tools, review labor and cost per accepted task. Compare the same workload across current API list prices without treating price as proof of equivalent quality.

The verdict: calculate the workload, not just the token price
A low input rate can still produce an expensive workflow. Retries, billed reasoning tokens, search or retrieval charges, human review and rejected outputs can outweigh the headline API price. This calculator keeps those components separate so you can see where the money goes.
Try it when you have token counts from a representative task and a clear acceptance test. Watch it when the model is in preview or the workflow depends heavily on provider tools. Skip the comparison when you are using guessed token counts or treating different models as equally capable without testing them.
What the estimate includes
- Ordinary input, cache reads, cache misses or writes, and billed output tokens.
- Base calls plus the share of tasks that need one extra retry.
- Optional tool or retrieval charges, review labor and fixed monthly costs.
- Optional cost per accepted task, using your post-retry acceptance rate.
- Optional comparison with your current cost per accepted task and implementation payback period.
The result does not include taxes, negotiated discounts, regional-processing premiums, cache storage, fine-tuning, infrastructure, or provider tools unless you add those charges. Google cache storage is specifically excluded because this MVP does not ask how long cached tokens remain stored.
How the calculation works
Monthly calls equal attempted tasks multiplied by base calls plus the retry rate. The calculator divides cacheable input into hits and misses, applies the documented rate for the selected processing mode, and adds output, tools, review labor and fixed costs. Accepted tasks equal attempted tasks multiplied by your post-retry acceptance rate. No ROI percentage is invented.
The 75%–125% sensitivity range changes workload volume while keeping fixed monthly costs unchanged. It is a narrow operating range, not a confidence interval or forecast.
Price is not a quality score
The tool can identify the lowest estimated API cost among the currently selected, eligible records. It cannot tell you whether the outputs are interchangeable. Run the same acceptance test on each candidate, measure retries and review time, and then compare cost per accepted task. Kingy’s token-budgeting guide explains that workflow, while the AI Model Intelligence Hub provides current access and source trails.
Pricing freshness and source policy
Every included record uses an official provider pricing page and official model documentation. A generally available model displays a warning after seven days without reverification and becomes unavailable after fourteen days. Preview and promotional records warn after 72 hours and become unavailable after seven days. A confirmed price change or broken official source excludes the record immediately.
Last verified: July 28, 2026. The calculator includes up to two models per major provider and does not claim a complete market ranking. OpenAI long-context rates are applied to the full request above the documented input threshold. Anthropic cache estimates use the five-minute write rate. Unsupported Batch or Batch-plus-cache combinations are blocked rather than inferred.
A better way to use this calculator
- Capture real input and billed output tokens from a small representative run.
- Define an acceptance test before comparing models.
- Measure the extra-call rate and human review time.
- Enter non-token charges instead of hiding them.
- Compare cost per accepted task, then test latency, reliability and policy fit separately.

Frequently asked questions
Why use cost per accepted task?
Token cost ignores failed or rejected work. Cost per accepted task includes the whole operating estimate and divides it by the outputs that meet your test.
Does the calculator choose the best model?
No. It compares documented list prices under the same assumptions. Capability, reliability, latency, safety and policy fit require workload testing.
Are my inputs stored?
No account or email is required, and the calculator does not put input values in a URL or browser storage. Prepared analytics events contain only an event name and tool version, and remain silent unless the site explicitly grants analytics consent.
