Quantity-Based Extrapolation

Definition

Quantity-Based Extrapolation is an algorithmic engine process that evaluates historical utility index readings and applies highly targeted mathematical projection models to simulate what a customer will predictably consume precisely up to the termination point of their next future scheduled billing sequence.

Business Purpose and Architecture

When a customer signs up for a massive 12-month equalized budget plan, the utility must accurately estimate a massive future lump sum to divide by 11. Architecturally, the engine performs a simulated “phantom” calculation natively utilizing Quantity-Based Extrapolation. It reads the customer’s base period, factors in seasonal adjustments built into the master weighting configurations, and projects forward. The resulting mathematically presumed value generated inside the Simulation document securely bypasses the real general ledger, functioning purely to seed the Budget Billing Plan’s baseline total.
