How much will a multi-agent workflow cost per run?
Before committing to a model, most teams orchestrating multiple cooperating agents want to estimate a multi-agent workflow's cost per run. This page does exactly that with an interactive calculator, so instead of guessing you get a concrete monthly cost grounded in today's provider prices.

Why this isn't trivial
The part people underestimate: several agents each hold their own context and message each other, multiplying token usage well beyond a single agent. In practice the biggest savings come from sharing a compact scratchpad instead of passing full transcripts between agents, so it is worth modelling before you commit.
How it's calculated
We estimate this by adding each agent's per-run token cost and the overhead of messages exchanged between them. Every figure uses the current provider prices baked into the site (reviewed daily), and you can override any input to match your own assumptions.
Frequently asked questions
Why are multi-agent systems expensive?+
Every agent maintains context and inter-agent messages add more tokens, so cost compounds.
Can fewer agents be cheaper and just as good?+
Often yes — collapsing roles reduces message overhead without hurting quality.
Are these prices up to date?+
Yes. The model prices behind this calculator are refreshed and reviewed daily, so your estimate reflects current provider rates rather than a stale snapshot.
