Free · No sign-up · Based on public model pricing

The sticker price is only 40% of what AI will cost you.

Per-token rates are the easy part. Add infra, dev hours, vector DBs, vendor lock-in, monitoring, and human review — and the real TCO is usually 2.5× the API bill. Model it below in 60 seconds.

Same use case, twelve different bills.

Your inputs, cross-tabulated against every model we support. The cheapest option isn't always the right one — but "right" shouldn't be off by 50×.

Break-even analysis

AI vs. the team you'd otherwise hire.

Replacing a workflow isn't about the subscription cost — it's about the fully-loaded human alternative, including benefits, tooling, and management overhead.

Would humans be cheaper at this volume?

Adjust the human baseline; we'll break down the cost-per-interaction both ways.

Where budgets leak

Six buckets nobody budgets for — until the invoice lands.

◢ 01 · Prompt drift

Evals, regression tests, A/B

Every model update re-rolls your prompts. Teams without eval pipelines ship regressions to prod on Tuesday and roll back on Thursday — twice a quarter, every quarter.

6–12% of AI TCO
◢ 02 · Context engineering

Vector DBs, embeddings, reranking

RAG isn't "upload PDF, done". Chunking strategy, hybrid retrieval, reranker costs, re-embedding on updates — this stack is typically 25–40% of infra spend.

25–40% of infra spend
◢ 03 · Vendor lock-in

Portability tax

Model-specific fine-tuning, function-calling schemas, cached prompts — all non-portable. Switching vendors later costs 3–6 weeks of engineering per non-trivial integration.

3–6 weeks switch cost
◢ 04 · Safety + compliance

Moderation, PII, auditability

GDPR, DORA, the EU AI Act. Logs, redaction, jailbreak-resistant system prompts, and a classifier pass on inputs and outputs. Not optional in regulated sectors.

8–15% of AI TCO
◢ 05 · Human review

HITL for the long tail

Even at 95% autonomous, the 5% you escalate demands an ops team, SLAs, and an escalation UI. Scales linearly with volume, not with compute.

~$0.40 per reviewed query
◢ 06 · Opportunity + idle cost

GPU reservations, wasted calls

Self-hosting? Reserved GPU hours burn 24/7 even when traffic dips. Using APIs? Failed retries, dropped streams, and timed-out agent loops quietly rack up 8–18% token waste.

8–18% token overrun
Methodology

Where the numbers come from.

We don't invent multipliers. Every assumption is sourced from a public price list or peer-reviewed benchmark — linked below.

◢ Token pricing

Vendor price pages

Input / output per-1M-token rates are pulled from OpenAI, Anthropic, Google DeepMind and Mistral price pages, refreshed quarterly. We model blended input-heavy workloads separately from generation-heavy ones.

Refreshed: Q1 2026
◢ Hidden multipliers

a16z LLMOps survey

Andreessen Horowitz's 2024 LLMOps survey across 40+ companies found infra+ops+dev roughly doubles the raw API bill. Our default multipliers sit at the median of the reported range.

◢ Retrieval stack

Pinecone + pgvector benchmarks

For RAG use cases, vector DB + embedding cost is modeled against Pinecone Serverless and self-hosted pgvector on RDS m5.xlarge. We assume 1M indexed chunks with nightly delta updates.

FAQ

Honest questions, honest answers.

Why is the "true" cost usually 2–3× the API bill?
Because the API bill is the floor, not the ceiling. You're also paying for: a vector DB (RAG), observability (Langfuse/Helicone), a moderation classifier pass, a senior engineer maintaining prompts and evals, and ops people handling the long tail. In our field data, the median ratio of hidden-to-API cost is 1.5×, meaning total ≈ 2.5× what the vendor quote said.
Does this cover fine-tuning and custom training?
Toggle the "Fine-tuning" option in Step 4. We amortize a single training run across 12 months at a mid-range LoRA cost (~$6k one-off). For full pre-training you're in another budget category entirely — book a call.
What about caching and prompt compression?
Anthropic's prompt caching and OpenAI's batch API both cut input costs 50–80% for cache-friendly workloads. The calculator doesn't apply this automatically — if your traffic is highly repetitive, shave the input price manually and you'll see the delta live. A good rule of thumb: cache covers 30–60% of input tokens for RAG workloads.
Why don't you show Azure / Bedrock / Vertex pricing?
For the same underlying model, Azure / Bedrock / Vertex rates are within ±5% of the direct vendor rate for on-demand usage. Enterprise agreements can shift this meaningfully — use the "Custom" model row and plug in your negotiated rate.
Is the human-comparison realistic?
It's a rough comparator. A real labor model should add benefits, onboarding, attrition, and management layer — we use a 1.3× loading factor by default, which lands in the published SHRM range for knowledge work. Reality will vary by country.
Can I export or share this estimate?
Hit "Copy summary" — it puts a plain-text cost breakdown on your clipboard. Your inputs also persist to local storage, so you can come back tomorrow and tweak.
