Inputs you will need
To estimate (and document) attorney fees in Brazil with DocketMath’s attorney-fee calculator, you’ll typically gather a small set of case inputs that determine (1) the fee “mode” and (2) the economic base the calculation uses.
Use this checklist to collect what DocketMath needs for BR (Brazil):
Choose the fee model that matches your workflow:
- Contractual hourly / by stage
- Contractual fixed fee
- Contingency-based (if your agreement is structured this way)
- Court-awarded fee expectation (if you’re estimating exposure or recoverable amounts)
Provide the amount the fee is calculated on, such as:
- Contested value (valor da causa) for many court-related projections
- Settlement amount (if you’re estimating outcome-based fees)
- Invoice / billing base (if your agreement uses hourly or milestone billing)
If the fee model uses a percentage, provide the agreed percentage (e.g., 10%, 20%, etc.).
If the fee model uses time:
- **Hourly rate (R$ / hour)
- Estimated billable hours
For stage-based fees, list each milestone (e.g., demand letter, initial petition, evidence stage)
Provide the fee per milestone or the stage percentage
Enter the retainer amount (R$) if your contract requires one.
Capture whether your fee inputs are:
- **Gross (includes tax)
- **Net (excludes tax)
If you want itemized outputs, note the tax regime assumption you’re using (without changing legal characterization).
Confirm amounts are in Brazilian reais (R$).
Confirm you’re running the calculator in Brazil (BR) so DocketMath applies BR-specific rules and data mapping.
Gentle note: In Brazil, “attorney fees” can refer to different things depending on whether you’re modeling a contractual fee or an award of sucumbência. DocketMath can help structure the estimate, but your inputs must reflect which category you’re trying to calculate.
Where to find each input
Here’s a practical guide to locating each item in documents you already have:
Most inputs live in the case file, contracts, or docket entries. Dates usually come from the triggering event notice; rates and caps come from governing documents or statute; and amounts come from the ledger or judgment. Record the source for each value so the run is reproducible.
1) Case type / fee model
- Contract template (fixed-fee, hourly, contingency, milestone)
- Engagement letter or mandate document
- Internal billing policy (if your firm uses standard rates)
2) Fee basis (monetary base)
- Valor da causa appears in:
- the initial petition (petição inicial)
- procedural filings referencing the “value of the claim”
- Settlement amount appears in:
- settlement agreement (acordo) or settlement proposals
- Billing base appears in:
- scope/billing spreadsheet
- invoice templates and time-entry reports
3) Percentage rate (if applicable)
- Fee clause in the attorney-client agreement
- Remuneration schedule for contingency or success fees
- Court-claim projections if you’re estimating based on a percentage range you expect to argue
4) Hourly rate + estimated hours (if applicable)
- Rate card (internal or contract exhibits)
- Time estimate from matter planning (project plan)
- Historical time entries for comparable matters
5) Milestones (if applicable)
- Scope-of-work section of the contract
- Docket/plan documents listing stages and deliverables
6) Retainer / advance
- Receipt / invoice for the retainer
- Payment confirmation or accounting ledger
7) Taxes / service charges handling
- Your invoice model
- Contract language on whether client-facing amounts are:
- all-in, or
- plus taxes
8) Currency
- Look for R$ formatting directly in:
- petitions
- agreements
- invoices
Run it

Step-by-step workflow
- Go to DocketMath → Attorney Fee calculator
Primary CTA: /tools/attorney-fee - Confirm Jurisdiction: Brazil (BR).
- Select the fee model that matches your documents:
- If you choose a percentage-based model, DocketMath needs the percentage rate and the fee basis.
- If you choose hourly, DocketMath needs hourly rate and hours.
- If you choose milestones, DocketMath totals the milestone fees and can apply retainer/tax logic depending on your setup.
- Enter amounts in R$.
- Add retainer and specify how you want tax treatment handled (gross vs net).
- Review outputs, typically including:
- Estimated attorney fee total
- Net vs gross split (when tax handling is provided)
- Comparison line items (for example, fee vs retainer offset, depending on tool configuration)
How outputs change when inputs change (sanity-check)
| Input you change | Typical direction of effect on output |
|---|---|
| Higher fee basis (e.g., valor da causa) | Fee estimate increases proportionally (percentage models) or scales (rate-based models) |
| Higher percentage rate | Output increases linearly with the chosen rate |
| More hours | Output increases linearly for hourly models |
| Higher milestone payments | Total increases by the sum of milestone amounts |
| Larger retainer | Output may reduce “amount due” if retainer is treated as an advance |
Tip: If you’re estimating a court-related figure, align your fee basis with what the court filings use (commonly valor da causa for many projections). Mixing settlement amounts and claim values can distort results.
