What's the difference between standard burden multiplier and effective burden multiplier?

Standard burden multiplier is a numeric multiplier derived from a burden schedule. The burden schedule is either assigned on the planning options or derived using actual cost rate derivation logic.

Effective burden multiplier is a numeric multiplier applied to raw cost to calculate burden cost amounts for financial planning. It equals the standard burden multiplier until you recalculate by entering a revised burdened cost or an effective burdened cost rate.
