What problem does it solve?

Fermi estimation provides quick, order-of-magnitude answers by decomposing unknown quantities into estimable factors, enabling faster decision support and planning.

Core Features & Use Cases

• Decomposition: break a question into measurable components that can be estimated with available data or reasonable benchmarks.
• Factor estimation: assign plausible ranges to each factor and combine them to derive a final estimate.
• Sanity checks: perform cross-validation and uncertainty bounds to ensure plausible results across scenarios.
• Use cases: capacity planning, cost estimation, market sizing, feasibility assessment, and prioritization in product and engineering work.

Quick Start

State the exact question, decompose it into estimable factors, estimate each factor, and compute the final order-of-magnitude result.
