Billing Units Explained: Why 6 Minutes Can Cost You Big

When it comes to legal billing, time is money — literally. Most law firms charge in billing units, typically in 6-minute increments (or one-tenth of an hour). That might sound harmless, but those tiny units can add up fast — and end up costing you thousands more than you expect.

At Law In Check, we regularly help clients check legal costs and uncover how billing units have inflated their final invoice. Here’s how these time increments work, why they matter, and what you can do to reduce solicitor fees and keep your costs in check.

What Are Billing Units?

Most lawyers in Australia record their time in 6-minute billing units. That means every hour of work is divided into ten equal parts — and each task, no matter how small, is rounded up to the next unit.

For example:

• A 2-minute phone call? Billed as 6 minutes.
• A quick 7-minute email? Billed as 12 minutes.
• Three short calls in one day? That could total 18 minutes of billable time — even if the actual work took less than 10 minutes.



This system is legal and widely used across the profession, but it often leads to inflated costs, especially in matters with frequent brief interactions.

Why Billing Units Add Up Quickly

It’s easy to underestimate how much these small increments affect your total bill. Every short task, email, and phone call is rounded up — and when multiplied across a long legal matter, it can add hundreds (or even thousands) to your final bill.

This is one of the most common ways clients unknowingly overpay, especially when their lawyer doesn’t provide clear, itemised descriptions of each time entry.

Ask your lawyer to provide detailed, itemised billing showing the actual time spent on each task. This helps you check legal costs and spot unnecessary rounding.

When Billing Units Become Unfair

While 6-minute billing units are standard, fairness depends on how they’re used. Problems arise when:

• Lawyers bill for multiple short tasks separately rather than grouping them.
• Administrative or routine tasks are billed as legal work.
• Time is rounded up excessively or inconsistently.



If you notice a pattern of very short entries all rounded up to 6 or 12 minutes, you might be paying more than is reasonable — and it may be possible to reduce solicitor costs through a review.

How to Check Whether You’ve Been Overcharged by Your Lawyer

You don’t need to be a legal expert to check legal costs effectively. Start by:

• Requesting an itemised bill – You have a legal right to see exactly how your fees were calculated.
• Comparing actual work with charges – Does the time billed align with what you recall happening?
• Asking about billing practices – Does your lawyer round up each task, or do they record actual time?



If something doesn’t look right, you can ask for clarification — or seek an independent review from a cost lawyer.
