Economic Order QuantityLive

Controls

Presets

Order too often and ordering costs pile up; order too much and holding costs balloon. The Economic Order Quantity, EOQ = √(2DS/H), is the order size that minimizes their sum. At the optimum the ordering and holding costs are exactly equal — the crossing point of the two curves. The foundation of inventory management.

▶ Run in Python

Data Inspector

EOQ707 units
Orders / year14.1
Min total cost$1414

Governing equation

Reading this result: At the EOQ the two curves cross: yearly ordering cost equals yearly holding cost, giving about 14.1 orders a year at the minimum total cost.

Monte Carlo Price SimulationLive

Controls

Presets

Geometric Brownian motion models a price with constant drift and random volatility — the assumption behind Black-Scholes. Running hundreds of simulated paths reveals the full distribution of outcomes, not just an average. Educational tool, not investment advice.

▶ Run in Python

Data Inspector

Median outcome$0
5th percentile$0
95th percentile$0

Governing equation

Reading this result: Median outcome is about $0, just under the drift-only $107 — GBM compounds in log-space, so volatility always pulls the typical path below the average.
