Economists help prove damages by calculating the lifetime dollar cost of an injury. A forensic economist, a specialist who measures economic loss for court, compares earnings without injury to earnings after injury.
That calculation supports a settlement demand or a trial award. It does not decide fault. It translates medical harm into present-day dollars a payer can understand.

What counts as lost earnings?
The core comparison is the but-for earnings path against post-injury earning ability. LegalClarity describes use of tax returns, pay records, and labor-market data over decades. The gap between the two paths is lost earning capacity.
Useful records to preserve include: Total pay includes more than wages. The U.S. Bureau of Labor Statistics reported in its June 2026 employer-costs release total compensation of $46.89 per hour, with $14.07 in benefits. Economists limit future losses to worklife expectancy, often using government worklife tables by age, education, and occupation.

How do future losses become today's dollars?
A jury cannot award future dollars as if they will arrive tomorrow. All future economic losses must be reduced to present cash value. The Judicial Council California Civil Jury Instructions CACI 3904A defines that term in its present cash value instruction as the lump sum that, if reasonably invested today, will provide the future amount.
The discount rate matters a great deal. A higher rate produces a lower present value. A lower rate produces a higher present value. Lawyers often contest this choice through competing experts.
What about medical care and home help?
The economist does not decide what treatment is needed. LegalClarity explains that the physician and certified life-care planner supply the itemized future-care plan. The economist then calculates its present value using wage growth, inflation, and discount rates.
Lost household services get separate value at market replacement cost. Tasks include cooking, cleaning, home maintenance, and childcare the injured person can no longer perform. A part-time home aide rate, for example, can show what replacement help would cost each week.
Will the jury hear the economist?
Federal courts screen expert proof before trial. Cornell Law School Legal Information Institute publishes Federal Rule of Evidence 702, which requires a qualified expert, helpful knowledge, sufficient facts, and reliable methods reliably applied. The judge acts as gatekeeper under Daubert.
Speculative or unsupported assumptions can be excluded. Courts closely review data quality and methods. Recent scholarship from the International Association of Rehabilitation Professionals notes that some states now bar race-based worklife tables because of discriminatory impact. Ask your lawyer which tables and assumptions your court accepts.
