When an agent carries all prior context forward, each step re-sends a growing memory, so cost climbs quadratically. Estimate a run's cost as memory accumulates step by step.
How this is calculated
This calculator uses the agents formulas described in our methodology. All figures are estimates for planning; verify current pricing with each provider before relying on them.

Frequently asked questions
How do I stop agent cost exploding?+
Summarize or trim memory between steps, store facts externally and retrieve only what's needed, and cache stable context. Unbounded memory grows cost with the square of steps.
