Step-by-step

Run this scenario in DocketMath using the Attorney Fee calculator.

This guide walks you through running attorney fee calculations in DocketMath for Canada using the Attorney Fee calculator. The goal is to help you get accurate, defensible numbers you can review and reuse—without turning the tool into legal advice.

1) Open the correct calculator

  1. Go to DocketMath: /tools/attorney-fee
  2. Select Canada (CA) if the jurisdiction prompt appears.
  3. Confirm you’re using the Attorney Fee calculator (not another pricing/timing tool).

2) Identify which fee method your calculation needs

DocketMath’s attorney-fee calculator typically relies on inputs like:

  • a billing structure (for example, hourly-based inputs—use the workflow you’re actually modeling),
  • time (hours by task or a single total),
  • optional multipliers/adjustments depending on the calculation you’re modeling,
  • and tax handling (if you’re including or excluding taxes in your estimate).

Before entering numbers, decide what you’re trying to estimate:

  • Budgeting (predictive estimate of what might be billed)
  • Reconciliation (comparing an invoice amount against modeled hours)
  • Submission prep (creating a fee breakdown to attach to a draft document)

Gentle note: This is a modeling workflow. Treat outputs as estimates unless you’re using exact agreement/invoice terms or documented rules from your matter.

3) Enter the required inputs (and double-check units)

In DocketMath, you’ll enter inputs that generally fall into these categories:

A. Parties to bill (optional, depending on your use)

If the calculator provides fields for party type or billed entity:

  • Use the same assumption consistently across runs.
  • Keep your naming consistent (e.g., “Client,” “Opposing party,” or “Own firm”) so any exports or copied results stay understandable later.

B. Billing rate(s)

Enter:

  • Hourly rate (e.g., 350 CAD/hour)
  • If the calculator supports multiple roles, enter each role’s rate (e.g., junior vs. senior)

Watch for these unit mismatches:

  • Rate must be per hour (not per 6-minute increment).
  • If you have time in minutes from a timesheet, convert to hours first (e.g., 90 minutes = 1.5 hours) before entering.

C. Time spent

You can usually do one of two approaches:

  • enter a single total (e.g., total hours for the matter), or
  • enter task-by-task hours if the calculator has line-item fields.

Tip: If your matter has “core” and “non-core” workstreams, consider running two calculations:

  • one for the core time
  • one for the non-core time
    Then compare totals side-by-side to see what’s driving the variance.

D. Adjustments / multipliers (if available)

If you model adjustments (for example, a premium/discount):

  • apply them intentionally
  • keep your reasons documented in your own workflow notes (outside the tool)
  • run a baseline and an adjusted version so you can show the effect of the change

E. Taxes (CAD and GST/HST handling)

If DocketMath includes tax toggles or tax inputs:

  • Use the tax scenario that matches your billing workflow (for example, taxes included in rates vs. taxes added after the subtotal).
  • If you’re unsure, run two versions:
    • Taxes excluded
    • Taxes included / taxes added

This helps avoid a common Canada fee estimate issue: mixing tax-inclusive and tax-exclusive assumptions can change the modeled total by roughly 5%–15%, depending on the rate and whether tax is added on top of already tax-included amounts.

Pitfall to avoid: Comparing totals from one run with taxes enabled and another with taxes disabled is not an apples-to-apples comparison. Compare either subtotals or ensure both scenarios use the same tax logic.

4) Review the calculation outputs

After you run the calculator, DocketMath should display:

  • a fee subtotal (generally based on time × rate, then any additions/subtractions),
  • optional tax totals, and
  • a grand total.

Use these checks:

  • Sanity check the math
    • Example: 10 hours × $300/hour should yield about $3,000 before adjustments.
  • Check rounding
    • Verify whether the tool rounds to the nearest dollar, cent, or hour fraction.
  • Confirm scenario selection
    • If there are toggles (like “include taxes”), make sure they match what you intended.

5) Use “what-if” runs to understand drivers

DocketMath is most useful when you iterate. Run multiple scenarios, such as:

  • Scenario A (baseline): current hours and rate
  • Scenario B (time variance): add/subtract 10–20% hours to reflect uncertainty
  • Scenario C (rate variance): adjust rate if staffing changes (for example, more senior time)

Then compare outputs in a simple internal table:

ScenarioHoursRate (CAD/hr)AdjustmentsSubtotal (CAD)TaxesTotal (CAD)
A Baseline12.0350None4,200(if on)
B Higher time14.4350None5,040(if on)
C Higher rate12.0400None4,800(if on)

6) Export or record results for reuse

If DocketMath lets you copy or export:

  • copy the totals plus the key inputs (hours, rates, adjustments, tax settings)
  • track versions in your workflow, e.g., “Matter X – Draft fees – v1”

Note: Keep in mind that DocketMath calculations are best treated as estimates and modeled breakdowns unless you’re using exact agreement terms, invoice data, or court-approved rules you’ve documented.

Common pitfalls

Below are issues that repeatedly affect Canadian attorney-fee calculations when using DocketMath. Avoid them early to reduce rework.

  • using gross recovery when net applies
  • mixing recoverable and non-recoverable time
  • skipping statutory prerequisites
  • forgetting fee caps or schedules

Capture the source for each input so another team member can verify the same result quickly.

1) Time entry mistakes (minutes vs hours)

  • Entering minutes as if they were hours inflates totals massively.
  • Incorrect seconds-to-minutes-to-hours conversions can still introduce meaningful drift.

Checklist

2) Rate confusion across roles

If your work includes multiple roles, ensure you didn’t:

  • use one blended rate for all time when the tool expects role-specific rates, or
  • apply a senior rate to junior time.

Checklist

3) Tax assumption mismatch

Canada fee estimates often depend on whether taxes are included in the rate or added afterward.

Checklist

Warning: If one scenario has taxes enabled and another does not, you can’t directly compare grand totals. Compare subtotals or ensure identical tax logic.

4) Double adjustments

If your workflow applies both multipliers and additional “adjustment line items,” you may be adjusting twice.

Checklist

5) Rounding and “fraction of an hour” interpretation

Billing practices differ (for example, rounding to fixed-minute increments vs. decimal hours). If DocketMath’s rounding differs from your timesheet practices, totals may diverge.

Checklist

Try it

  1. Open the DocketMath Attorney Fee calculator: /tools/attorney-fee
  2. Choose Canada (CA).
  3. Enter a small test case first:
    • Example: 2.0 hours at 350 CAD/hr, no adjustments, taxes off
  4. Confirm your subtotal is 700 CAD.
  5. Then turn on taxes (if available) and re-run:
    • verify the total increases in a way that matches your expectations
  6. Finally, run a realistic case:
    • enter your estimated hours and primary billing rate
    • create a second scenario with +15% hours to quantify uncertainty

If your test case outputs look correct, you’re ready to model your actual matter.
