Most law firm owners know what they pay their staff. Fewer know what admin work costs across the whole firm.
The salary on your profit and loss statement is only the visible cost. Hidden costs include lost billable time, late invoices, missed intake calls, and routine tasks that pull attorneys away from legal work.
This guide shows you how to calculate those costs. It also explains which tasks can move to trained legal support.
How Much Time Do Lawyers Spend on Administrative Tasks?
Lawyers spend a large part of each workday on time that is not billed.
What the Utilization Data Shows
Clio’s 2025 Legal Trends Report found an average utilization rate of 38%. Clio defines utilization as the share of an eight-hour day used for billable work. At 38%, about three hours are billable and five hours are not billed.
Those five hours are not all admin work. They may also include business development, training, breaks, and firm management.
The 2023 State of U.S. Small Law Firms Report from Thomson Reuters gives a more direct view. Small-firm lawyers said they spent 61% of their time practicing law and 9% on admin tasks.
These studies use different methods. The numbers should not be treated as the same measure.
Common Administrative Tasks
Admin work often includes:
- Answering calls and screening new leads
- Scheduling meetings and consultations
- Managing calendars and reminders
- Formatting and filing documents
- Entering time and preparing invoices
- Following up on unpaid bills
- Requesting and organizing records
- Sending routine client updates
Each task may take only a few minutes. Together, they can take many hours each week.
A delegation matrix for lawyers can help your firm separate legal work from tasks that support staff can handle.

1. Direct Cost: What Administrative Support Actually Costs
Start With Pay
The U.S. Bureau of Labor Statistics reported that legal secretaries and administrative assistants earned an average annual wage of $60,620 in May 2025. The median hourly wage was $26.72.
These are national figures. Actual pay can change by location, experience, and firm size.
Add Benefits and Employer Costs
Base pay is only part of the cost. An in-house employee may also require:
- Payroll taxes
- Health insurance
- Paid leave
- Retirement benefits
- Recruiting and training
- Equipment and software
- Office space
- Coverage during leave
- Turnover and replacement costs
BLS data for March 2026 showed that private employers with 1 to 49 workers spent $37.36 in total compensation for every $27.68 in wages. That is about 1.35 times the wage cost.
A Simple Estimate
Using that general ratio, a $60,620 wage would equal about $81,800 in wages and benefits.

This is only an estimate. It combines BLS national wage data for one occupation (Occupational Employment and Wage Statistics, May 2025) with benefit data for small private employers across many industries (Employer Costs for Employee Compensation, March 2026). Your firm's actual cost may be higher or lower.
This is only an estimate. It combines national wage data for one job with benefit data for small private employers across many industries. It also does not include hiring, software, equipment, office space, or turnover.
When you plan to reduce law firm overhead, compare the full cost of each option. Do not compare salary alone.
2. Opportunity Cost: The Billable Time You Lose
Opportunity cost is the value of work your attorneys could have done instead.
Every hour spent on scheduling, billing, file work, or routine follow-up is an hour that cannot be used for client work or firm growth.
Use This Formula
Weekly admin hours × working weeks × effective hourly rate
Use the effective rate, not the listed rate. The effective rate is what your firm collects after discounts, write-offs, and unpaid bills.
Example
One attorney spends eight hours each week on admin work:

48 weeks
working year
384 hours
per attorney
$250
effective rate
$96,000
lost per attorney, per year
Across three attorneys
$288,000
These are sample numbers, not an industry average. Use your own admin hours and effective hourly rate. Not every saved hour becomes a paid hour.
These are sample numbers. They are not an industry average.
Not every saved hour will become a paid hour. Still, the example shows why attorney time can become the largest hidden cost.
Improving law firm productivity often starts with moving routine work to the right support role.
Your attorneys should not be doing admin work.
We will show you which tasks a trained virtual legal assistant can take over, and what that support would cost your firm.

Leakage cost is money the firm could have earned but did not capture.
It often comes from missed calls, slow follow-up, late billing, and weak collection steps.
Missed Intake Calls
Clio’s 2024 secret-shopper study contacted 500 law firms by phone and email. Only 40% answered the first phone call. After firms had time to call back, 48% were still unreachable by phone. Only 33% replied to the test email.
This does not mean every law firm misses 48% of real calls. It does show that many possible clients have trouble reaching a firm.

A remote legal intake specialist can answer calls, collect lead details, schedule meetings, and manage follow-up.
Slow Follow-Up
A lead may contact the firm but wait too long for a reply, meeting time, or next step.
The effect of response speed can change by practice area and lead type. Track your own law firm intake response time instead of relying on broad sales claims.
Late or Missing Time Entries
Work may be done but never entered into the billing system.
When lawyers enter time days later, they may miss tasks or record less time than they worked.
Late Invoices and Old Receivables
A firm cannot collect payment until it sends the bill. Late invoices make the wait for payment even longer.
Clear law firm billing best practices can help the team enter time, send bills, and follow up on unpaid accounts.
How to Calculate Your Law Firm Administrative Costs
Use these steps to build a simple yearly estimate.
Step 1: Add Direct Costs
Include:
- Salary or contractor fees
- Taxes and benefits
- Hiring and training
- Equipment and software
- Workspace
- Leave coverage
- Turnover costs
When comparing options, review the full legal staffing costs of local versus remote support.
Step 2: Add Opportunity Cost
For each attorney, calculate:
Weekly admin hours × working weeks × effective hourly rate
Then add the results for the whole firm.
For a better estimate, ask each attorney to track admin work for two weeks.
Step 3: Estimate Intake Leakage
Start with numbers your firm already has:
- Missed or unanswered calls
- Leads that did not get a reply
- Consultations booked
- New clients signed
- Average collected matter value
Use these numbers to estimate how much weak follow-up may cost.
Step 4: Check Billing Leakage
Review:
- Late time entries
- Work that was not billed
- Late invoices
- Write-downs
- Unpaid bills
- Old receivables
- Accounts with no follow-up
Do not count the same lost amount twice.
Step 5: Add the Three Costs
Your total is:
Direct cost + opportunity cost + leakage cost
Step 6: Compare Staffing Options
Do not compare support with zero cost.
The admin work will still exist. If no one owns it, attorneys or other staff will do it.
In-House Admin vs. Virtual Legal Assistant
In-house admin vs. virtual legal assistant
| Factor | In-House Admin | Virtual Legal Assistant |
|---|---|---|
| Cost | Salary plus employer costs | Monthly or hourly fee |
| Benefits | Paid by the firm | Depends on the setup |
| Recruiting | Managed by the firm | May be handled by a provider |
| Equipment | Usually provided by the firm | May be provided by the worker or provider |
| Office space | May be needed | Usually not needed |
| Leave coverage | Managed by the firm | May be offered by the provider |
| Scaling | Usually slower | May be easier |
| In-person tasks | Available | Not available |
| Replacement help | Managed by the firm | May be offered by the provider |
An in-house role may be better for walk-in clients, original papers, court runs, or other in-person work.
A virtual role may work well for calls, billing support, file work, scheduling, and other tasks done online.
A virtual legal assistant hiring guide can help your firm review skills, security, communication, and supervision before hiring.
Which Admin Tasks Should Lawyers Delegate First?
Start with work that is routine, repeatable, and does not need legal judgment.
Phone and Intake
Support staff may:
- Answer calls
- Collect contact details
- Record basic matter facts
- Schedule meetings
- Send reminders
- Follow a set follow-up process
Calendar Support
Support staff may:
- Enter dates given by attorneys
- Schedule meetings
- Send reminders
- Update shared calendars
- Follow written deadline steps
The lawyer and firm still own legal deadlines.
Billing Support
Support staff may:
- Check time-entry gaps
- Prepare draft bills
- Send approved bills
- Track unpaid accounts
- Prepare aging reports
Document and Records Support
Support staff may:
- Format documents
- Use approved templates
- Name and save files
- Build exhibit sets
- Upload approved files
- Track record requests
- Flag missing items
Routine Client Updates
Support staff may:
- Send appointment details
- Request missing documents
- Send approved status updates
- Share scheduling changes
Support staff must not give legal advice.
A list of tasks attorneys should delegate can help your firm find more work that should move off an attorney’s desk.
How to Cut Admin Costs Without Hurting Service
Removing support does not remove the work. It only moves the work to someone else.
Use these steps to lower costs while keeping service strong.
Track the Work
Ask each attorney to track admin tasks for two weeks.
Use simple groups, such as intake, billing, scheduling, records, file work, and client follow-up.
Separate Legal Work From Admin Work
Ask:
- Does this task need legal advice?
- Does it need legal judgment?
- Can someone follow a written process?
- Can support staff prepare it for lawyer review?
Legal advice, strategy, and final legal choices stay with the attorney.
Write the Process Down
For each task, record:
- When the task starts
- Who owns it
- What steps to follow
- When a lawyer must review it
- When to raise a problem
- Where to record completion
Strong law firm systems make delegation easier and reduce missed steps.
Frequently Asked Questions
- Missed calls
- Slow follow-up
- Late time entries
- Late invoices
- Old unpaid bills
- Lawyers doing routine admin work after hours
Choose the Right Support Role
Legal support work has special terms, privacy rules, and filing steps.
Check the person’s real experience. Do not assume every assistant has the same skills.
An administrative assistant for a law firm may handle daily workflows while attorneys keep control of legal work.
Review the Results
After 30 to 60 days, review:
- Attorney admin hours
- Billable hours
- Intake response time
- Invoice speed
- Old receivables
- Missed tasks
- Client service problems
If attorney admin time does not fall, the process may need clearer steps or more support.
Your attorneys should not be doing admin work.
