How Bookkeeping Helps Determine the Effective Rate for Each Billing Attorney
An attorney’s effective rate is what the firm actually collects for each hour worked. It’s almost always lower than the standard billing rate, because some time is written off before it’s billed and some billed time is never collected. Tracking it by attorney shows where revenue is leaking.
The Three Numbers Behind Effective Rate
Utilization: billable hours compared with available working hours. Are attorneys spending their time on billable work?
Realization: hours billed compared with hours worked. How much time gets written down before the invoice goes out?
Collection: dollars collected compared with dollars billed. How much of the billed work is actually paid?
Realization and collection determine the effective rate. Utilization doesn’t change the rate itself, but it determines how many hours that rate applies to.
How to Calculate Effective Rate
Effective rate = fees collected ÷ hours worked
You can get the same result by multiplying three numbers:
Effective rate = standard rate × realization rate × collection rate
Example: An attorney with a $400 standard rate, 80% realization and 85% collection has an effective rate of $400 × 0.80 × 0.85 = $272 per hour worked.
Why the Highest Billing Rate Isn’t Always the Most Productive
Attorney A: $450 standard rate, 75% realization, 80% collection = $270 effective rate
Attorney B: $375 standard rate, 90% realization, 95% collection = $321 effective rate
Attorney B bills at a lower rate but brings in about $51 more for every hour worked.
Where Bookkeeping Comes In
Time data lives in your practice management software, such as Clio, MyCase, or Timeslips. Collection data lives in your books. To measure effective rate accurately, the two have to agree.
When they don’t, the numbers are wrong. Duplicate payments, retainers booked as income, and unapplied payments all distort realization and collection figures. Clean, reconciled books connected to your billing software make these numbers reliable. See: Clio & QuickBooks Bookkeeping.
What to Do With the Numbers
Low realization: look at write-down habits, fee agreements, and scope creep.
Low collection: review billing timing, payment terms, and follow-up on overdue invoices.
Low utilization: look at workload balance and time spent on non-billable work.
Use the findings in conversations about rates, staffing, and compensation.

Frequently Asked Questions
What is an attorney’s effective billing rate?
It’s the amount the firm actually collects for each hour an attorney works. To calculate it, divide fees collected by hours worked, or multiply the standard rate by the realization and collection rates.
What’s the difference between realization rate and collection rate?
Realization measures how much worked time gets billed. Collection measures how much billed time gets paid. Both reduce the amount the firm actually receives compared with the standard rate.
What is a good realization rate for a law firm?
It varies by practice area, fee arrangement, and client mix. The most useful comparison is each attorney’s rate over time and against others in the firm. A falling realization rate usually points to write-downs, scope creep, or pricing problems worth looking into.
Can Clio calculate effective rate?
Clio and other practice management tools include reports on billed and collected time. Those reports are only as accurate as the underlying data. If payments, retainers, or write-offs aren’t recorded correctly in both systems, the results will be off.
How often should a firm review effective rates?
Quarterly works for most firms, and monthly works for firms actively managing pricing or staffing. Reviewing over several months smooths out the timing of large collections.
