Understanding 6-Minute Tenths Billing in Legal Practice

In law firms across the United States, United Kingdom, Australia, and Canada, attorney time is divided into 10 billing increments per hour (6 minutes per increment, or 0.1 hours).

The Ceiling Rule
Unlike standard mathematical rounding, legal retainer contracts specify ceiling rounding. Any fraction of a 6-minute block rounds up to ensure attorneys are compensated for initiating work.
Capturing Micro-Tasks
A 2-minute client phone call or 4-minute email response is billed as 1 tenth (0.1 hr). Firms using tenths capture 15–20% more billable revenue than firms using 15-minute blocks.
Direct Arithmetic
Tenths convert to clean base-10 decimal numbers (0.1, 0.2, 0.3...). Multiplying decimal hours by hourly rates (Hours × Rate = Total Fee) eliminates base-60 invoicing errors.
Standard 6-Minute Billing Increments:
1–6 min: 0.1 hr (1 unit)
7–12 min: 0.2 hr (2 units)
13–18 min: 0.3 hr (3 units)
19–24 min: 0.4 hr (4 units)
25–30 min: 0.5 hr (5 units)
31–36 min: 0.6 hr (6 units)
37–42 min: 0.7 hr (7 units)
43–48 min: 0.8 hr (8 units)
49–54 min: 0.9 hr (9 units)
55–60 min: 1.0 hr (10 units)
