Net expectation-style loss starts with direct damages plus lost profits, minus mitigation credit (not below zero). Liquidated damages are added as a separate line when you are modeling an enforceable clause. The gross total is scaled by case strength and reduced for defense risk, then shown with a negotiation band.
Net expectation loss = max(0, direct + lost profits − mitigation)Gross = net expectation loss + liquidated damagesAdjusted = gross × strength × (100% − defense %)Terms, breach, causation—then remedies and defenses
Illustrative recovery after strength and defense risk: $35,178; negotiation-style band $28,846 – $39,399.
Consequential damages, interest, and fee awards are not included—consult an attorney.
