How is API usage estimated from hours?

Each usage type implies a typical token throughput per active hour — coding generates more output than chat. The tool multiplies that by your hours, team size, and 22 working days, then prices it with representative API rates.

Why is a subscription sometimes cheaper than the API?

Flat plans like Copilot or Claude.ai Pro bundle heavy usage at a fixed price. For power users who run many hours daily, metered API calls can exceed the flat fee, making the subscription the cheaper choice.

When does the API win?

The API typically wins for light or bursty users, automated background workloads, and cases where you only pay for what you consume. Below the break-even hours the tool reports, pay-per-use is cheaper.

Does this cover both seats and tokens?

Subscriptions are priced per seat per month across your team. API cost is usage-based and shared, so the comparison reflects how flat per-seat pricing scales differently from metered consumption as the team grows.

Yes, and many teams should. Put steady interactive users on subscriptions and route automated or spiky workloads to the API. Use the break-even figure to decide which users belong on which plan.

LLM Subscription vs Pay-Per-Use Optimizer

LLM subscription vs pay-per-use optimizer

Flat subscriptions like GitHub Copilot, Claude.ai Pro, and Gemini Advanced are simple to budget, but for some workloads metered API pricing is dramatically cheaper — and for others it is far more expensive. This optimizer estimates your real token footprint from how your team actually works and compares the monthly subscription bill against equivalent API spend, with a break-even point so you know which side of the line you are on.

How it works

You pick a usage type, set active hours per day per person, and a team size. Each usage type maps to a typical token throughput per active hour — coding emits more generated tokens than chat or analysis. The tool projects monthly tokens across your team over 22 working days, prices them at representative API rates, and compares that to the per-seat subscription cost for the same headcount. It then reports which is cheaper and the daily-hours break-even where the two costs meet.

Tips and notes

Split your team. Heavy interactive users often belong on subscriptions; automated jobs belong on the API.
Background work favors the API. You only pay for tokens consumed, with no idle seat cost.
Re-check after a price change. Both subscription tiers and API rates move; re-run when they do.
Hours are the lever. The break-even is mostly about active hours per day — watch that number more than team size.
