Business arithmetic for running a practice, not legal advice. Fee agreements, contingency limits, trust accounting and advertising are all governed by the rules of professional conduct where you practise, and several are strict. Check the applicable rules before any of this affects a client agreement or a marketing decision. Concurrent load matters more than annual throughput for service quality, because it is what determines whether anything gets dropped. Matters that run longer than expected are the normal case rather than the exception, which is why the reserve is not optional.

Questions

About this calculator

Why does matter duration change the answer?

Because a matter open for a year occupies a slot for a year even if it only consumes twenty hours. Concurrent load is driven by duration, not by hours.

What happens above capacity?

Response times slip first, then deadlines get tight, then something is missed. Overloading is a professional risk before it is a commercial one.

The formula

annual matters = usable billable hours / hours per matter; concurrent = annual matters x duration / 12
