What this calculator does

Run this scenario in DocketMath using the Wrongful Death Damages calculator.

DocketMath’s Wrongful Death Damages Estimator (Washington) is designed to help you estimate a damages range and understand what typically drives the number in a Washington wrongful death case. It’s meant for early planning and budgeting—not for predicting outcomes with certainty.

In Washington, wrongful death damages usually focus on categories tied to the decedent’s survivors’ losses, rather than a single lump-sum formula. This estimator helps you structure those losses into inputs you can adjust:

  • Economic losses (commonly income the person would have earned, plus certain related financial impacts)
  • Non-economic losses (commonly loss of companionship, support, comfort, and related harms)
  • Time period assumptions (how long the loss is projected to continue)
  • Comparative or offset concepts (where applicable to how damages are modeled)

Because wrongful death cases involve multiple fact patterns, this tool produces an estimate/range, not a legal determination.

Note: This guide is about estimating damages and preparing inputs. It is not legal advice and does not replace case-specific analysis.

When to use it

Use this estimator when you want to:

  • Model different scenarios (for example, comparing a conservative vs. optimistic earnings projection)
  • Understand sensitivity—how much the estimate changes when you adjust:
    • decedent’s earnings,
    • expected work life,
    • household contribution assumptions,
    • survivor needs and relationship factors
  • Plan deadlines and investigation steps ahead of filing

Statute of limitations (SOL) timing in Washington

Washington’s general/default statute of limitations is 5 years. The general statute is RCW 9A.04.080. No claim-type-specific sub-rule was found for this estimator guide, so the 5-year period should be treated as the default SOL for wrongful death claims in this practical context.

Key takeaway for planning:

  • If you’re working on a wrongful death matter, treat RCW 9A.04.080’s 5-year SOL as your starting point for deadline planning unless a case-specific rule changes the analysis.

Warning: SOL questions can get complex based on the facts and procedural posture. Use this as a planning baseline, and verify the applicable timing for your specific situation before relying on any schedule.

Step-by-step example

Below is a realistic walkthrough using the kinds of inputs you’ll typically enter in DocketMath’s estimator. Since this is an estimator, you’ll see an estimate/range that changes as you update assumptions.

Step 1: Enter basic case context

Assume:

  • Decedent: 42 years old
  • Estimated working years remaining: 15 years (you may model differently based on retirements, health, or employment pattern)
  • Survivor relationship: spouse and one child

What you’re doing: establishing the loss horizon and who may be affected.

Step 2: Model economic losses (income-based inputs)

Example assumptions (illustrative):

  • Recent annual income (gross or net, depending on how the tool requests it): $70,000
  • Expected annual growth/adjustment: 0% (conservative)
  • Additional household contribution factor: 60% of income treated as the decedent’s household contribution (the tool may ask for a contribution percentage)

How outputs change:

  • Higher income → higher economic-loss component
  • Longer loss horizon → higher economic-loss component
  • Higher household contribution percentage → higher estimate

Step 3: Add non-economic components (relationship and harm)

Example assumptions (illustrative):

  • Spouse companionship/support loss: modeled at a level you choose based on the decedent’s role in the household
  • Child companionship/support loss: modeled separately

How outputs change:

  • Stronger day-to-day relationship factors you enter → higher non-economic component
  • Reduced frequency of interaction (based on facts) → potentially lower non-economic component

Pitfall: Non-economic inputs can swing the estimate substantially. If you’re unsure, run two scenarios—one “baseline” and one “high” level of demonstrated relationship impact—to see how sensitive the results are.

Step 4: Run the estimate and review the range

After inputting assumptions, DocketMath produces:

  • an estimated damages range (structured by category where applicable),
  • and a total estimate summary.

For this example (illustrative), you might see something like:

  • Economic losses: (range)
  • Non-economic losses: (range)
  • Total estimated damages: (range)

Even without exact figures here, the key point is that the total is an aggregation of the categories you modeled.

Step 5: Refine inputs using “what-if” adjustments

Try three quick adjustments to understand drivers:

  1. Income adjustment test: change annual income from $70,000 to $75,000
  2. Work-life horizon test: reduce loss horizon from 15 years to 12 years
  3. Contribution test: change household contribution from 60% to 55%

Compare how the total changes. This helps you decide which facts matter most for evidence collection (pay stubs, tax returns, employment history, caregiving role, etc.).

Common scenarios

Wrongful death loss patterns are not one-size-fits-all. Here are common Washington scenarios you can model in a structured way, along with what usually changes in the estimator.

1) Young adult decedent with stable employment

Typical modeling factors:

  • Higher remaining work-life horizon
  • More years for income-based projection
  • Non-economic components often reflected as significant due to the strength of ongoing relationships

Estimator sensitivity:

  • Income and loss horizon usually move the estimate more than small changes in non-economic assumptions.

2) Middle-aged decedent with irregular income or self-employment

Typical modeling factors:

  • Income estimation may require averaging
  • Contribution assumptions can be more nuanced

Estimator sensitivity:

  • Income inputs and the method you use to represent earnings consistency (averages, recent trend) can swing results.

3) Decedent supporting multiple survivors (spouse + children)

Typical modeling factors:

  • Economic contribution may be allocated across survivors (tool may ask for contribution details or survivor-specific inputs)
  • Non-economic losses may be modeled per survivor category

Estimator sensitivity:

  • Non-economic inputs often matter for a spouse and children in different ways, so run separate scenarios per survivor if the tool supports it.

4) Decedent with health/uncertainty affecting the projected horizon

Typical modeling factors:

  • Reduced expected work-life horizon
  • Different assumptions for continuing earning capacity

Estimator sensitivity:

  • Changing the projection horizon can reduce both economic and total estimates.

Tips for accuracy

You’ll get more useful results when you treat the estimator like a structured worksheet—tighten assumptions where you can, and run “range” scenarios where you can’t.

Checklist for better inputs

  • baseline scenario with best available estimate,
    • and a conservative alternative if work-life is uncertain
    • baseline
    • high/low sensitivity depending on what you think is most uncertain

Practical evidence mapping (so inputs aren’t just guesses)

To make your numbers defensible within an estimate, map inputs to evidence you can obtain:

Estimator inputCommon support you may be able to gatherWhy it matters
Recent earningsPay stubs, W-2s, tax filingsDrives economic-loss projection
Work-life horizonEmployment pattern, typical retirement age assumptionsSets how long losses accumulate
Household contributionCaregiving role, documented support, financial contribution patternsAdjusts how income translates into survivor impact
Relationship impact (non-economic)Daily involvement evidence, family role description, school/work caregiving contextDrives the non-economic component
Assumptions about growth/inflationHistoric earnings trend, budgeting approachAffects compounding across years

Keep SOL planning in the front of your workflow

Washington’s default SOL is 5 years under RCW 9A.04.080 (general/default period; no claim-type-specific sub-rule was found in this guide). Even if you aren’t ready to finalize valuation, start organizing inputs now so you can:

  • document earnings,
  • identify survivor impacts,
  • and preserve essential records.

Warning: Delays can create avoidable deadline pressure. Use the estimator early to decide what facts you need to collect next.
