Claim Settlement vs Litigation Cost Comparator
Compare the total expected cost of settling an insurance claim out of court versus pursuing litigation, accounting for legal fees, probability of outcomes, time value of money, and indirect costs.
Formulas Used
1. Present Value (PV) Discount Factor:
PV_Factor(n) = 1 / (1 + r_monthly)^n where r_monthly = Annual Rate / 12
2. Settlement Present Value Cost:
PV_Settlement = (Settlement Offer + Settlement Legal Fees) × PV_Factor(Settlement Months)
3. Expected Litigation Verdict (Expected Value):
E[Verdict] = P(Win) × Verdict_Win + P(Lose) × Verdict_Lose
4. Litigation Present Value Cost:
PV_Litigation = (E[Verdict] + Legal Fees + Expert Costs + Indirect Costs) × PV_Factor(Litigation Months)
5. Net Savings from Settling:
Savings = PV_Litigation − PV_Settlement
Positive savings → Settle; Negative savings → Litigate
6. Breakeven Win Probability:
P_breakeven = [PV_Settlement / PV_Factor(Litigation Months) − Verdict_Lose − Legal Fees − Expert Costs − Indirect Costs] / (Verdict_Win − Verdict_Lose)
If the actual probability of plaintiff winning exceeds P_breakeven, litigation becomes more expensive than settling.
