Medical Malpractice Damages Estimator
Estimates potential medical malpractice damages including past and future medical expenses, lost wages, loss of earning capacity, and non-economic damages such as pain and suffering. Results are estimates only and do not constitute legal advice.
### Medical Expenses
Past Medical Expenses ($):
Future Medical Expenses (Annual $):
Years of Future Medical Care Needed:
### Lost Income
Past Lost Wages ($):
Annual Income Before Injury ($):
Years of Future Earning Capacity Lost:
Percentage Reduction in Earning Capacity (%):
### Non-Economic Damages
Pain & Suffering Multiplier (1–5):
Applied to total economic damages. Use higher values for severe, permanent injuries.
State Non-Economic Damages Cap ($ — 0 if none):
### Discount Rate & Adjustments
Discount Rate for Future Damages (%):
Used to calculate present value of future losses (typical range: 2%–5%).
Estimated Liability / Fault Percentage (%):
Reflects likelihood of proving full liability (0–100%).

#### Formulas Used
Economic Damages
- Past Medical Expenses: Actual costs already incurred (no discounting).
- Future Medical Expenses (PV): PV = Annual Cost × [1 − (1 + r)⁻ⁿ] / r, where r = discount rate, n = years of care.
- Past Lost Wages: Actual wages lost to date (no discounting).
- Future Loss of Earning Capacity (PV): Annual Loss = Annual Income × (Reduction % / 100); PV = Annual Loss × [1 − (1 + r)⁻ⁿ] / r.
- Total Economic = Past Medical + PV Future Medical + Past Wages + PV Future Earning Loss
Non-Economic Damages
Final Estimate
#### Assumptions & References
- Future damages are discounted to present value using a standard annuity formula consistent with Jones & Laughlin Steel Corp. v. Pfeifer, 462 U.S. 523 (1983).
