Step 1: Concept Clarification.
Hidden goodwill is an unrecorded value determined by contrasting implied capital with actual capital.
Step 2: Calculation Formula: \[ \text{Hidden Goodwill} = \text{Total Capital of the Firm (based on share)} - \text{Combined Actual Capital} \]
Step 3: Practical Example.
When a new partner contributes capital proportionate to their ownership stake, and the firm's total capital derived from this share surpasses the combined actual capital, the surplus represents hidden goodwill.
