Example inputs

Run this scenario in DocketMath using the Attorney Fee calculator.

Below is a worked example of how attorney-fee calculations typically look in United States (Federal) matters, using DocketMath’s attorney-fee calculator as the workflow.

Note: This example illustrates math and inputs. It is not legal advice, and federal fee statutes and case-specific rules can affect what’s allowable.

Scenario (federal civil case)

A plaintiff wins a motion on liability and later settles after a short period of discovery. The fee request covers work performed by counsel from January through March.

We’ll assume the request is analyzed using a common federal-fee framework that starts with reasonable hours × reasonable rate, with possible adjustments and later reductions for limited success.

Inputs (what you’d enter into DocketMath)

Use these categories because fee outcomes often turn on (1) which hours count and (2) what rates count.

InputExample valueWhat it represents
Lodestar hourly rate (standard)$450/hourThe market rate for comparable federal litigation
Attorney hours billed (covered work)120 hoursHours you claim are compensable
Paralegal hourly rate$120/hourMarket rate for paralegal/legal assistant time
Paralegal hours billed18 hoursParalegal hours you claim are compensable
Multiplier (optional)1.10Upward or downward adjustment after lodestar (use 1.00 if not used)
Success reduction %20%Reduction for partial success (e.g., you won some claims but not all)
Administrative/clerical exclusion %10%Fraction of attorney hours not compensable (e.g., purely clerical time)
Costs included?YesWhether to include reimbursable costs in a “total” output

Derived assumptions used in this example

To keep the math transparent, this example applies two reductions:

  1. Success reduction: reduce attorney and paralegal hours by 20%
  2. Clerical exclusion: reduce attorney hours by 10% (paralegal time often already reflects non-clerical work; we’ll leave it unchanged for simplicity)

If you prefer a different reduction scheme, you can mirror it in DocketMath by adjusting the reduction fields (or setting the reduction inputs to 0%).

Costs (included as a separate line)

Costs often include things like filing fees, transcript costs, and service charges (depending on the governing rule and what’s documented). For this example:

  • Taxable/documented costs: $3,250
  • No separate “expert” costs included here

Example run

Here’s the step-by-step run as it would look conceptually in an attorney-fee calculator.

Run the Attorney Fee calculator using the example inputs above. Review the breakdown for intermediate steps (segments, adjustments, or rate changes) so you can see how each input moves the output. Save the result for reference and compare it to your actual scenario.

Step 1: Reduce hours for clerical/administrative time

Attorney hours billed: 120
Clerical exclusion: 10%

  • Compensable attorney hours = 120 × (1 − 0.10)
  • Compensable attorney hours = 120 × 0.90 = 108.0 hours

Paralegal hours: 18
We apply only the success reduction (no clerical exclusion in this example).

Step 2: Apply success reduction

Success reduction: 20%

  • Compensable attorney hours after success = 108.0 × (1 − 0.20)

  • = 108.0 × 0.80 = 86.4 hours

  • Compensable paralegal hours after success = 18 × 0.80

  • = 14.4 hours

Step 3: Compute lodestar components

Attorney lodestar

  • 86.4 hours × $450/hour = $38,880

Paralegal lodestar

  • 14.4 hours × $120/hour = $1,728

Total lodestar before multiplier

  • $38,880 + $1,728 = $40,608

Step 4: Apply multiplier

Multiplier = 1.10

  • Adjusted fee = $40,608 × 1.10
  • Adjusted fee = $44,668.80

Step 5: Add costs (if included)

Costs included? Yes

  • Costs = $3,250

Total requested amount

  • $44,668.80 + $3,250 = $47,918.80

Output (what DocketMath would display)

A typical output breakdown includes:

Output lineValue
Compensable attorney hours86.4
Compensable paralegal hours14.4
Attorney fee (lodestar)$38,880.00
Paralegal fee (lodestar)$1,728.00
Lodestar subtotal$40,608.00
Multiplier-adjusted fee$44,668.80
Costs$3,250.00
Total fees + costs$47,918.80

Checklist: inputs that most affect the number

Use this to audit your DocketMath entry before finalizing a fee narrative.

For the fastest workflow, start with hours and reductions first—rates and multipliers refine the outcome.

Sensitivity check

Small input changes can move the total materially. Below are “what-if” swings using the same underlying assumptions, adjusting one input at a time.

To test sensitivity, change one high-impact input (like the rate, start date, or cap) and rerun the calculation. Compare the outputs side by side so you can see how small input shifts affect the result.

A) Change the success reduction from 20% to 10%

  • Attorney hours after success: 108 × 0.90 = 97.2
  • Paralegal hours after success: 18 × 0.90 = 16.2

Attorney lodestar: 97.2 × 450 = $43,740
Paralegal lodestar: 16.2 × 120 = $1,944
Lodestar subtotal: $45,684
Multiplier 1.10 → $50,252.40
Add costs $3,250 → $53,502.40

Change vs. base ($47,918.80): +$5,583.60

B) Change the multiplier from 1.10 to 1.00

  • Lodestar subtotal remains $40,608
  • Multiplier 1.00 → $40,608
  • Add costs $3,250 → $43,858.00

Change vs. base: −$4,060.80

C) Increase attorney rate from $450 to $475/hour (keep everything else)

Attorney fee increases by ($475 − $450) × 86.4 = $2,160

  • Base attorney fee: $38,880
  • New attorney fee: $41,040
  • Paralegal unchanged: $1,728
  • Lodestar subtotal: $42,768
  • Multiplier 1.10 → $47,044.80
  • Add costs $3,250 → $50,294.80

Change vs. base: +$2,376.00

Practical takeaway

Most fee disputes (and negotiation leverage points) usually cluster around:

  1. Success reduction (claim-by-claim outcome)
  2. Compensable hours (clerical/admin trimming and exclusions)
  3. Rate support (comparable attorney/paralegal rates)
  4. Whether a multiplier applies (often the largest discretionary swing)

If you’re running multiple drafts, treat sensitivity checks as part of your workflow:

  • Use a baseline
  • Apply ±10% on success reduction
  • Compare multiplier 1.00 vs 1.10
  • Swap rates within a realistic band supported by your evidentiary record
