Why do attorneys bill in 6-minute increments?

The 6-minute increment system (tenths of an hour) provides a standardized, fair billing method that accurately captures small tasks while remaining easy to calculate and track throughout the day.

What is billing efficiency?

Billing efficiency shows the ratio of billable hours to actual hours worked. Due to rounding up to 6-minute increments, this typically exceeds 100%, meaning you bill slightly more than actual time worked.

How should I track multiple tasks throughout the day?

Enter each distinct task separately with its start and end time. This calculator automatically converts each entry to billable hours and provides a total summary for accurate client billing and time management.

Legal Billing Guide

Maximize billable time

Expert Tips

Track Time Immediately: Record time as you work, not at the end of the day. Memory-based billing leads to lost revenue and inaccuracies.
Use Appropriate Increments: Bill in reasonable increments—typically 6 or 15 minutes. Be consistent and transparent with your billing practices.
Set Realistic Targets: Understand what billable percentage is achievable. Not all working hours are billable—admin, marketing, and training time are necessary but unbillable.
Value Your Expertise: Experienced attorneys can charge higher rates for complex work. Don't underprice specialized knowledge.

Essential Fundamentals — Billing basics

Time Tracking

Contemporaneous Recording: Record time as you perform work. Studies show attorneys lose significant billable time when reconstructing time at day's end.
Detailed Descriptions: Write clear, specific task descriptions. Vague entries invite disputes and payment delays from clients.
Billable vs Non-Billable: Understand which activities are billable. Client development, training, and admin are necessary but typically non-billable.

Advanced Strategies — Increase productivity

Billing Optimization

Block Similar Tasks: Group similar work together. Task switching costs time, and focused blocks are more efficient and easier to bill accurately.
Regular Billing Review: Review your billing patterns monthly. Identify where time is leaking and adjust practices to capture more billable work.
