Example inputs
Run this scenario in DocketMath using the Wage Backpay calculator.
This worked example shows how you can estimate wage backpay in Brazil using DocketMath with jurisdiction-aware wage backpay logic. It’s a practical walkthrough of inputs, assumptions, and how the output responds when you adjust key variables.
Note: This is a worked example for calculation workflow and scenario analysis. It’s not legal advice and can’t replace case-specific analysis of evidence, claim terms, and court/settlement outcomes.
Scenario overview (what happened)
A worker sues for unpaid wages after a termination dispute. The employer stopped paying wages on 2023-02-01. The worker continues the claim through 2024-03-31, and the court (or settlement) recognizes backpay covering that period.
To keep the example concrete, we’ll treat the backpay as monthly wage amounts earned during the period (excluding separate items like overtime, bonuses, or benefits unless you add them as inputs).
Core inputs for DocketMath (Brazil / BR)
Use these as the starting point for DocketMath’s wage-backpay calculator:
- Jurisdiction: Brazil (BR)
- Pay frequency: Monthly
- Wage rate (base monthly wage): R$ 3,200.00
- Backpay start date: 2023-02-01
- Backpay end date: 2024-03-31
- Pre-judgment period handling: “Accrue by period overlap” (calculator’s internal method for counting eligible days/months)
- Compensation components included:
- Base wages (required)
- Statutory adjustment/late-payment factor: enabled (jurisdiction-aware setting in the tool)
- Simple interest style: enabled (jurisdiction-aware setting in the tool)
- Rounding: to the nearest centavo (R$)
How to think about the inputs (so you can adjust them)
Here’s what each field changes:
- Wage rate scales the result almost linearly—doubling the base wage roughly doubles wage backpay, subject to rounding and how the calculator apportions partial periods.
- Start/end dates control the covered time span. Move the start by 1 month and you’ll usually see a proportional change, especially when the calculator apportions monthly earnings by eligible days.
- Enabled components (adjustment and interest) can create non-linear differences. If you disable them, you’ll often drop a substantial portion of the total—especially for long periods.
Quick sanity check: the number of months/days
From 2023-02-01 to 2024-03-31 includes:
- February–December 2023: 11 months
- January–March 2024: 3 months
- Total: 14 months (with day-level handling inside the calculator)
That means the “base wages only” estimate starts around:
- 14 × R$ 3,200.00 = R$ 44,800.00
The full DocketMath output will then add Brazil-specific adjustment/interest components per its wage backpay calculator rules.
Example run
Run the calculator at /tools/wage-backpay.
Run the Wage Backpay 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-by-step: entering inputs
Using DocketMath (Brazil / BR wage backpay):
- Select the jurisdiction: BR (Brazil).
- Choose the pay frequency: Monthly.
- Enter:
- Wage rate: R$ 3,200.00
- Start date: 2023-02-01
- End date: 2024-03-31
- Confirm the calculation toggles:
- Include statutory adjustment/late-payment factor: ON
- Include interest component: ON
- Run the calculation.
Example output (illustrative, using DocketMath workflow)
A typical DocketMath wage backpay output breaks down totals like this:
| Output component | What it represents | Amount (R$) |
|---|---|---|
| Base wages | Unpaid wages for the covered period | 44,800.00 |
| Statutory adjustment factor | Currency/time adjustment per tool’s BR rules | 7,120.00 |
| Interest component | Time value/late-payment interest per tool’s BR rules | 5,680.00 |
| Estimated wage backpay total | Sum of included components | 57,600.00 |
Estimated wage backpay total in this scenario: R$ 57,600.00.
What you should watch in the breakdown
- Base wages match the 14-month core earnings logic (44,800.00).
- Adjustment and interest are additive and can be large relative to base wages. In this example, combined adjustment+interest equals R$ 12,800.00, or about 28.6% of base wages.
Mapping outputs back to litigation realities (without legal advice)
In Brazil, wage claims often involve multiple components (e.g., salary, overtime, severance-like items, benefits, and sometimes court-ordered corrections). This calculator focuses on wage backpay inputs you specify.
If your claim includes additional wage-related categories, handle them by:
- Running separate calculations per category (if DocketMath supports multiple wage lines), or
- Adjusting the inputs to reflect all included wage types bundled into the “wage rate” field (only if that reflects your case evidence).
Sensitivity check
A good wage backpay estimate is more than one number. Below are targeted changes that typically move the result the most.
Warning: Changing dates or toggling adjustment/interest can change totals materially. Always rerun the calculator after any modification to the wage period or included components.
Sensitivity A — shift the start date by 1 month
Keep everything constant except:
- New start date: 2023-03-01 (instead of 2023-02-01)
Effect:
- Base wages drop from 14 months to 13 months
- Base wages estimate becomes: 13 × R$ 3,200.00 = R$ 41,600.00
- Adjustment and interest generally decrease too because the tool applies time-based components over the shorter period.
Expected direction: total decreases.
A realistic outcome pattern:
- Base wages: ↓ ~ R$ 3,200.00
- Adjustment+interest: ↓ more than R$ 0 in addition (because fewer months accrue)
Sensitivity B — change monthly wage rate by +10%
Keep dates constant and change:
- Wage rate: R$ 3,520.00 (10% higher)
Effect:
- Base wages: 14 × 3,520.00 = R$ 49,280.00
- Adjustment and interest usually scale with the base (since the underlying amount being adjusted/discounted is higher).
Expected direction: total increases roughly proportionally, with some variation due to rounding and date apportionment.
Sensitivity C — turn off interest component
If you toggle:
- Interest component: OFF
Effect:
- You remove the time-based interest amount (in the example run, that was R$ 5,680.00).
Expected direction: total decreases by approximately the excluded interest component, while base wages and adjustment remain.
Sensitivity D — change end date by +15 days
Change:
- End date: from 2024-03-31 to 2024-04-15
Effect:
- The tool’s day-level apportionment increases the covered period slightly.
- Expect a partial-month increment (not a full month), depending on DocketMath’s period overlap logic.
Expected direction: total increases, but not necessarily by a full “monthly wage” amount.
Summary table (directional impact from this scenario)
| Change | Base wages impact | Adjustment/interest impact | Net total expected |
|---|---|---|---|
| Start date +1 month later | Decrease (~R$ 3,200.00) | Decrease (less time) | Down |
| Wage rate +10% | Increase | Increase (usually proportional) | Up |
| Interest OFF | Same | Decrease (interest removed) | Down |
| End date +15 days | Increase (partial) | Increase (partial) | Up |
