Supply Chain Calculators
Lead time, fill rate, OTIF, forecast accuracy and demand planning calculators for supply chain teams.
OTIF Calculator
OTIF is the single most widely used supplier scorecard metric in retail because it's binary and unforgiving by design: an order that arrives on time but short a case doesn't count, and an order that's complete but three days late doesn't count either. You end up with the OTIF percent and the distance from a 95 percent target. The distance is the part that starts the supplier conversation.
(Orders On Time and In Full ÷ Total Orders) × 100

Demand Planning Calculator
Weighted moving average forecasting solves a specific problem: a simple average treats three months ago and last month as equally predictive of next month, which is usually wrong. This calculator applies default weights (0.2 / 0.3 / 0.5) that lean toward the most recent period without fully discounting the trend history, giving planners a fast, defensible baseline forecast without needing statistical software.

Warehouse Capacity Calculator
A warehouse's nameplate pallet-position count overstates real usable capacity every time, because no warehouse operates at 100 percent utilization without productivity collapsing. Usable capacity comes back in real units, built on a utilization assumption you set, rather than the theoretical maximum nobody ever hits.
Pallet Positions × (Utilization ÷ 100) × Units per Pallet
