What are billable hours?
Billable hours are time spent on client work that a law firm can charge under its engagement terms and billing policy. They differ from total hours worked because administration, training, and business development may not be chargeable. A 1,900-hour annual goal converts to about 158 billable hours per month before adjusting for leave and workload. The examples in this guide range from about 142 to 192 hours per month; they are planning examples, not a universal target.
Which work counts as billable?
Billable work depends on the client agreement, the firm’s billing policy, and any applicable billing guidelines. Drafting a motion, advising a client, or reviewing matter documents may be chargeable when the work is within scope. Internal meetings, marketing, and general administration usually are not. Record the work accurately first, then decide what belongs on an invoice during review.
Write a time entry that tells the client what was done and why it mattered to the matter. A precise entry is easier to review than a block of vague time. If a client has special billing rules, set them before the work begins so attorneys and staff do not have to reconstruct the invoice later.
Billable time is also distinct from an amount already billed. An attorney may record an hour of eligible work, but a reviewer may reduce it before invoicing. The firm then must collect the invoice. Keeping these stages separate makes monthly targets more useful.
Key takeaways
- Convert an annual goal to a monthly baseline: The 1,700–2,300-hour examples below equal about 142–192 hours a month. They are planning examples, not a universal standard.
- Separate time from revenue: Captured hours, billed hours, and paid invoices tell different parts of the story.
- Review monthly: A monthly view reveals a shortfall early enough to adjust work allocation or targets.
If you’re managing a mid-sized law firm, an annual billable-hours goal can be hard to use in week-to-week staffing decisions. Converting it to monthly and daily requirements makes the workload visible and helps you test whether the goal fits your team’s capacity.
Clio’s published billable-hours analysis reports 2.9 billable hours per workday in its dataset. That figure describes observed activity in that source, not a target for every firm. The gap between time at work and time billed is why capacity planning needs more than an annual goal.
Let’s dive into what monthly billable hours really look like for mid-sized law firms and, more importantly, how to actually hit those targets without burning out your team.
How many billable hours per month do annual targets require?
Convert the annual target
The conversion examples below use annual goals from 1,700 to 2,300 hours. They are not a current industry average. NALP’s historical analysis found that most reporting offices with a minimum required 1,800 or 1,900 hours; expectations vary by firm.
Let’s do the math:
| Annual billable-hour goal | Monthly average (annual ÷ 12) | Daily average (20 workdays) |
|---|---|---|
| 1,700 | 142 | 7.1 |
| 1,900 | 158 | 7.9 |
| 2,100 | 175 | 8.8 |
| 2,300 | 192 | 9.6 |
For example, a 1,900-hour annual goal averages about 158 billable hours a month. The daily column assumes 20 working days and does not account for leave or nonbillable duties. For a broader annual view, read how many billable hours are in a year.
The Reality Behind the Numbers
To bill 158 hours in a month with 20 working days, an attorney would need to average 7.9 billable hours on each of those days. Meetings, administration, and leave still need time on the calendar. Compare the daily requirement with the attorney’s actual recent capacity before assigning that goal.
The annual billable-hours guide provides another way to compare a yearly expectation with available working days. A daily target that already fills nearly the whole workday leaves little room for the firm’s other duties.
Adjust for days actually available
Dividing by 12 gives a quick monthly average, but available days are a better planning denominator. Start with the attorney’s scheduled workdays for the year. Subtract planned vacation, holidays, leave, and training. Divide the annual billable goal by the remaining days to see the billable hours needed on each available day.
For example, a hypothetical 1,900-hour goal spread across 240 available days requires about 7.9 billable hours a day. If only 220 days are available, the same goal requires about 8.6. The goal did not change, but the daily capacity required did. This check can reveal when a target needs more staffing, different work allocation, or a lower expectation.
How should targets vary by firm and practice area?
Differences by firm and practice
Firm size, client mix, and practice area can change how much time is available to bill. A litigation team may have concentrated trial periods; a transactional team may have closing deadlines; a general practice may have a steadier mix of matters. Review the last year of actual client work before assigning different goals. If an attorney spends substantial time managing staff or developing clients, account for those duties rather than treating every working day as fully billable.
Geographic differences
Location and local hiring markets may also affect firm expectations. Compare your target with the work your team can actually staff and collect, rather than applying another market’s requirement without adjustment.
How do billable hours become collected revenue?
Billable hours do not equal collected revenue. The financial funnel has four stages:
- Hours Worked: Total time your attorneys are at work
- Billable hours: Time that can be charged to clients
- Billed hours: Time that makes it onto invoices after review
- Collected revenue: What clients actually pay
Measure your firm’s utilization, realization, and collection rates rather than assuming that every recorded hour becomes cash.
Track the handoff between stages
At month-end, compare recorded eligible time with time that appeared on invoices. Review reductions for patterns: unclear descriptions, duplicate work, billing-guideline limits, or delayed entry. Then compare invoiced amounts with payments received. A target based only on entered time can look healthy even when substantial work is reduced or invoices remain unpaid.
For a useful team dashboard, show each attorney’s captured time, billable time approved for invoicing, write-downs, and collections for the same period. Keep the definitions consistent across months. That lets managers see whether a change came from workload, time capture, invoice review, or payment timing.
To follow that handoff in software, review how law firm time tracking software captures work by matter and how a smart billing workflow moves approved entries into invoices. The legal billing software buyer’s guide compares the broader financial approaches.
How can you calculate your firm’s monthly target?
Step 1: Start with Your Financial Goals
Work backwards from what you need to collect:
- Annual revenue goal ÷ Average hourly rate = Collected hours needed
- Collected hours ÷ Collection rate = Billed hours needed
- Billed hours ÷ Realization rate = Billable hours needed
- Billable hours ÷ 12 months = Monthly billable target
Step 2: Factor in Your Reality
Average billable hours per month do not include holidays, sick leaves or vacation days. When setting monthly targets, consider:
- January: Post-holiday slowdown
- July/August: Summer vacations
- November/December: Holiday interruptions
- Your practice area’s busy seasons
Step 3: Build in Buffers
You can plan on months when you have more capacity for billable hours so that in the lower capacity months, you’re not stressed about having a lower number. Smart firms set higher targets for their busy months to compensate for predictable slow periods.
Put the annual goal and the monthly plan side by side. If a month includes a trial, closing, or major transaction, its expected workload may support a higher target. If it includes planned leave, a lower target may be sensible. Review the plan each quarter against actual matters, rather than asking attorneys to make up a missed month without checking whether enough client work is available.
How can time tracking help capture billable work?
The Time Tracking Revolution
Time tracking tools can make short client tasks easier to record and help managers see work in progress before invoices are prepared.
Real-Time Tracking Beats Memory
If you track work as you go, you are less likely to forget short tasks by day’s end. Time and expense tracking can connect entries to the right matter, while the billing increment chart helps staff record time consistently.
The Integration Advantage
Firms using cloud-based billing integrated with QuickBooks see invoices paid up to 70% faster. Compare options in our legal billing software guide.
Which habits help a firm meet its monthly goal?
1. Make Daily Tracking Non-Negotiable
Set a firm-wide policy: all time must be entered daily. No one wants to get caught two weeks later trying to remember what he was doing two weeks in the past.
2. Implement the Right Billing Increments
Most lawyers bill in standard increments, with 1/10 of an hour (six minutes) as a common increment. This standardization:
- Makes calculations easier
- Ensures consistency across the firm
- Reduces client disputes
- Speeds up invoice preparation
3. Focus on realization rates
Review what gets reduced or written off before invoices go out. Clear descriptions and timely follow-up can help clients understand the work and pay outstanding bills.
4. Leverage Alternative Fee Arrangements Strategically
For suitable matters, compare hourly billing with flat fees or payment plans. Measure the effective rate and collection results for each arrangement before changing your pricing policy.
5. Monitor Monthly, Adjust Quarterly
Take the total number of required hours per year and divide it by twelve. The result is an associate’s monthly goal. But don’t stop there:
- Review individual performance monthly
- Analyze firm-wide trends quarterly
- Adjust targets based on actual realization and collection rates
- Provide support to attorneys falling behind early, not at year-end
What can derail a monthly billable-hours goal?
The February Trap
Shorter working months require a higher daily average to meet the same monthly target. Plan around the actual calendar and scheduled leave.
The Summer Slide
If your firm expects a summer slowdown, build that into the annual plan rather than treating each month as identical.
The Write-Off Spiral
Poor time descriptions lead to client challenges and write-offs. Use detailed but succinct descriptions to ensure clear, transparent billing.
Review write-offs by reason, not only by amount. A write-off caused by a client billing rule calls for a different fix than one caused by a late or unclear time entry. Where a matter repeatedly requires more work than its budget allows, revisit scope and staffing instead of merely pushing the monthly hour target higher.
The Utilization Illusion
Working more hours doesn’t always mean more billable hours. Focus on increasing the percentage of billable work, not just total hours at the office.
How can you put a monthly target into practice?
Week 1: Assess Your Current State
- Calculate your firm’s current utilization, realization, and collection rates
- Identify your top performers and understand what they’re doing differently
- Review which practice areas or attorneys consistently miss targets
Week 2: Set Realistic Targets
- Use the calculation framework above to set monthly goals by attorney
- Factor in seniority levels (partners vs. associates vs. paralegals)
- Build in seasonal variations
Week 3: Implement Technology Solutions
- Deploy time tracking software if you haven’t already
- Set up automated reminder systems for daily time entry
- Create dashboards for real-time monitoring
Week 4: Establish Accountability Systems
- Institute weekly billable hours check-ins
- Create monthly performance reviews
- Celebrate wins and address shortfalls quickly
What makes a billable-hours target sustainable?
Set targets using the firm’s actual work mix and capacity. Review captured time, billed time, and collections together so that a higher billable-hour count does not hide write-offs or unpaid invoices.
The 1,900-hour example averages about 158 billable hours per month, but that is not a suitable target for every attorney. Adjust a target for leave, practice area, staffing, and collection results.
Start with a monthly baseline, compare it with actual work, and revise it when the firm’s conditions change. Review LeanLaw pricing if you are evaluating connected time tracking and billing on QuickBooks Online.

Frequently asked questions
What is the difference between billable hours and hours worked?
Hours worked include all time spent on firm work. Billable hours are time spent on client work that the firm's agreement and billing policy allow it to charge. Administrative work, training, and business development are usually tracked separately.
How many billable hours per month should a lawyer target?
There is no universal target. The annual examples in this guide range from 1,700 to 2,300 hours, or about 142 to 192 hours per month when divided by 12. Choose a target using your own staffing, work mix, time off, and collection goals.
Are billable hours the same as collected hours?
No. A time entry can be billable but later reduced before invoicing, written off, or left unpaid. Track captured time, billed time, and collections separately to understand the full revenue cycle.
Should each month have the same target?
An annual goal divided by 12 is a planning baseline. Adjust month-by-month expectations for holidays, leave, court schedules, and your practice's busy seasons while keeping the annual goal visible.
