Estimate past financial losses and the present value of future medical care, lost earning capacity, household services, and other measurable costs.
What the economic damages calculator estimates
Economic damages are the financial losses an injured person or surviving family can identify through bills, wage records, care plans, employment history, or replacement-cost evidence. In personal injury and wrongful death matters, the calculation commonly starts with losses already incurred and then values financial losses expected in later years. This calculator is limited to that measurable portion of a claim. It addresses past medical expenses, past lost wages, other past out-of-pocket losses, future medical or care costs, future lost earning capacity, household services, and one-time future costs such as equipment or home modifications.
Economic-damages valuation treats past and future losses differently. A documented medical charge from a prior year is a past loss and is entered at face value. A future care plan is an expected annual stream that can increase over time and is discounted to present value. Separating those categories makes the estimate easier to review. This page therefore reports both an undiscounted nominal total and a present-value total for the future-loss components.
This economic damages calculator provides a transparent starting point before a claim receives a more detailed damages analysis. It can help test how documented past losses, annual future losses, duration, growth, and discount assumptions affect the estimate. It is a planning tool rather than legal advice, and it does not determine which losses are legally recoverable.
What belongs in each economic damages field
The first three economic-damages fields record past losses. Past medical expenses can include documented treatment, therapy, medication, hospitalization, transportation for care, or related medical needs, depending on the claim. Past lost wages or income are earnings already missed because the injured person could not work or had to reduce hours. Other past out-of-pocket costs cover documented expenses that do not fit the first two categories, such as travel, temporary home help, damaged assistive items, or replacement expenses already paid.
The next three economic-damages fields record recurring future annual losses. Future medical or care costs are the anticipated yearly costs of treatment, attendant care, therapy, medication, rehabilitation, or similar support. Future earning-capacity loss is the anticipated annual reduction in the ability to earn, rather than wages already missed. Household-services replacement value is the yearly value of chores, childcare, transportation, meal preparation, maintenance, or other services that must be replaced or that the household loses in practical economic terms.
The remaining fields set the economic-damages time horizon and valuation assumptions. Duration of future losses is the number of years the annual losses are expected to continue. Growth / cost increase rate lets each recurring annual loss rise over time. Discount rate converts future annual losses into present dollars. One-time future costs is for a single future expense, such as equipment or a home modification. Under this calculator's code, the one-time future amount is counted at its entered amount in both the nominal and present-value totals; it is not discounted from a specified future year.
How economic damages future-loss math works
This economic damages calculator adds past losses directly. It models each recurring future category as an annual stream that may grow each year, then discounts that stream to present value. Its nominal total instead adds future dollars without discounting them.
At the highest level, the economic damages estimate equals past losses, the present value of the three recurring future categories, and the entered one-time future cost:
For every recurring future economic-loss stream, the calculator uses the present value of a growing annuity. It begins with the annual amount entered today, applies the growth rate each year, and discounts each year-end amount by the discount rate:
In this economic-damages formula, A is the starting annual amount, g is the annual growth rate, r is the discount rate, and n is the number of years. The nominal, undiscounted total for that same growing annual stream is:
For recurring economic damages with zero growth, the nominal amount is simply the annual amount multiplied by years. When the growth and discount rates are equal, the calculator uses the corresponding simplified present-value calculation. Those special cases are handled by the script.
The inputs that usually have the greatest effect on a long-term economic-damages estimate are the annual earning-capacity, care, and household-service amounts; the number of years; and the relationship between growth and discount. Verify whether each amount is annual, confirm that the duration fits the evidence, and review whether the rate assumptions are appropriate for the analysis.
Worked example: present value of future economic damages
Suppose an economic damages claim includes $45,000 in past medical expenses, $30,000 in past lost wages, and $5,000 in other past out-of-pocket costs. Past losses are therefore $80,000. Assume annual future medical or care costs of $12,000, annual future earning-capacity loss of $25,000, annual household-services replacement value of $6,000, a 20-year duration, 2% annual growth, a 4% discount rate, and $18,000 in one-time future costs. These figures are illustrative assumptions, not a statement of any particular claim.
With those economic-damages inputs, the present value of future medical costs is about $193,000, future earning-capacity loss is about $402,000, and household services are about $97,000. Adding those recurring present values to $80,000 in past losses and the $18,000 one-time future cost produces a present-value estimate of about $790,000. The nominal total is about $1.14 million because it adds the future growing annual amounts without discounting them.
This economic-damages example illustrates why nominal and present-value figures answer different questions. Nominal damages describe the aggregate future dollars expected over time. Present value expresses those future dollars in today's dollars using the stated discount assumption. The difference is especially important when a care need or earning-capacity loss continues for many years.
How discount-rate assumptions affect economic damages
Long-term economic damages are sensitive to the relationship between the growth and discount rates. With the illustrative inputs above, changing only the discount rate changes the present-value total as follows:

When growth and discount are equal, each recurring annual amount is discounted for its year of payment but does not shrink relative to the prior year's amount. |

A higher discount rate reduces the present value of the recurring future losses. |
These economic-damages scenarios do not establish that any one rate is correct. They show why rate assumptions deserve close attention in a claim with many future years. Comparing multiple rate assumptions can make clear which valuation choices are driving the present-value result.
How to interpret this economic damages result
After you calculate economic damages, the highlighted result is the total economic damages in present value. The table beneath it separates past losses, future medical or care, future earnings loss, household services, and one-time future costs. Each row displays a nominal total and a present value, so the future-loss assumptions remain visible instead of being folded into one unexplained figure.
If an economic-damages result seems unexpectedly high or low, review the component rows. A high result can arise when an amount intended to be monthly was entered as annual, when the future duration is too long, or when growth is higher than intended. A low result can arise from omitting an annual category, entering only part of an annual amount, or choosing a discount rate far above the growth rate.
When future duration is zero, the calculator assigns no value to the recurring future economic-loss streams. The estimate then consists of past losses plus the entered one-time future cost. Similarly, an annual future amount of zero contributes nothing for that category.
Economic damages this calculator does not include
This calculator estimates economic damages only. It does not calculate pain and suffering, emotional distress, loss of consortium, punitive damages, liability apportionment, comparative fault reductions, prejudgment interest, tax effects, attorney fees, or jurisdiction-specific caps. It also does not decide whether an expense or income loss is legally recoverable. Those issues depend on evidence, local law, expert testimony, and the presentation of the claim.
The economic-damages model also assumes recurring future payments occur at the end of each year. It does not provide monthly discounting, separate growth rates by category, delayed starts for future losses, survival probabilities, work-life expectancy adjustments, fringe benefits, or separate medical-inflation assumptions. A claim requiring those features needs a customized analysis or expert economic report.
Practical assumptions for using economic damages estimates
Economic damages estimates are most useful when the assumptions are compared openly. Enter one set of documented amounts and rates, review the result, and then change one major input at a time. A substantial change after adjusting years, growth, or discount identifies an assumption that materially affects the claim's financial valuation.
Keep a record of the economic-damages assumptions behind any total you share. Comparisons become misleading when they use different durations, inconsistent annual amounts, or different growth and discount rates. This calculator makes those assumptions visible, but records, qualified experts, and applicable legal standards remain necessary for a final claim analysis.
