Quick takeaways
  • 1Output tokens usually cost 4–8× more than input — keeping replies short is the highest-leverage cost saver.
  • 2Anthropic prompt caching drops repeat-input cost by ~90%; OpenAI cached input drops it by ~90% on GPT-5.
  • 3DeepSeek off-peak hours are ~50% cheaper than peak — schedule batch jobs accordingly.
  • 4Gemini 2.5 Pro doubles its input price above 200K context — large-context calls cost roughly twice as much.

OpenRouter markup, explained

OpenRouter charges a small markup on top of each provider's official API price. The current average is around 5%, but the exact markup varies per model and per credit package. For most single-model workloads the overhead is small; it gets painful when you pay per request with many small models, or when you don't need OpenRouter's fallback / multi-model routing at all.

Current average markup: ×1.05 (5%)

When going direct is cheaper

If your workload is single-model, high-volume, and latency-sensitive, going direct to the provider's API almost always wins: lower latency, no aggregator in the request path, and you can negotiate volume pricing the aggregator can't match. OpenRouter wins when you need (a) automatic fallback across providers, (b) one bill for many models, or (c) access to models that aren't available on your home region.

Token Cost Calculator

How to bring the bill down

  1. 1Use a smaller model for routing / classification — Haiku 4.5 / GPT-5 nano cost roughly 5–10× less than the flagship.
  2. 2Cache repeat prefixes (system prompts, tool schemas) — Anthropic cached input drops the rate by ~90%.
  3. 3Set max_tokens explicitly — output is the expensive side; capping it prevents runaway replies.
  4. 4Batch non-urgent jobs into DeepSeek off-peak hours for ~50% cheaper inference.
  5. 5Trim long context — Gemini 2.5 Pro doubles its input rate above 200K; chunk documents that don't need the rest.

Frequently asked questions

What does OpenRouter actually charge?
OpenRouter charges the provider's official API price plus a small markup (typically 5%) for the routing, billing, and fallback service. The exact markup varies per model — check the model's card on OpenRouter for the current number.
Is OpenRouter more expensive than going direct?
For most single-model, high-volume workloads, going direct to the official provider is slightly cheaper because you skip the markup. OpenRouter wins when you need automatic fallback across providers, a single bill for many models, or access to models not available in your home region.
How much does 1 million tokens cost on OpenRouter?
It depends on which model you route to. For GPT-5 it's about $1.31 input / $10.50 output per 1M tokens (after the 5% markup on the official $1.25 / $10). For Claude Sonnet 4.5: $3.15 / $15.75. Use the calculator above to compare every model on OpenRouter against its official price.
Does OpenRouter charge per request?
No per-request fee — just the per-token markup on top of the underlying model price. The total is the same shape as a direct API call; the only difference is the small multiplier.
Can I use my own provider API key with OpenRouter?
Yes — OpenRouter lets you bring your own keys (BYOK) for some providers. When you do, you pay the provider's official rate with no OpenRouter markup. When you don't, OpenRouter bills you for both the tokens and the markup.
How accurate is this calculator?
The base model prices come from each provider's official pricing page; the OpenRouter column multiplies those by the current average markup factor (about 5%). Re-check the model's source link before relying on a number for billing.
Which models are available on OpenRouter?
OpenRouter aggregates most major models — GPT-5 family, Claude Opus / Sonnet / Haiku 4.5, Gemini 2.5 Pro / Flash, DeepSeek V3 / R1, and many open-source models. Check the live catalog at openrouter.ai/models for the current count (it changes weekly).
How often are these OpenRouter prices updated?
Whenever the underlying provider changes its price, the OpenRouter markup-adjusted column above updates on the same cadence. The "Updated YYYY-MM-DD" stamp and /api/prices.json both reflect the latest verification.
