The year felt full. So where did the money go?

Four numbers go in, and the chain they describe has three joints. None of them is mysterious.

Start with the hours the period actually had. Take off the hours nobody docketed: the ones that went into intake calls that did not become files, into the practice-management system, into a colleague's problem, into the drive to the courthouse. What's left is your docket, and the share of the period it represents is your utilization.

Then take off the hours that never reached an invoice. Work in progress you haven't billed yet. Time you wrote down because the file ran long and you didn't want the argument. The junior's first draft you wouldn't put in front of a client. What survives is your realization, and it is a fraction of your docket, not of your day.

Last, the money. Invoices go out and some of them don't come back, or come back slowly, or come back short. Collected over invoiced is your collection rate.

Follow the chain all the way through and you have what actually reached the bank. Divide that by the hours you docketed and you have your effective rate, what an hour you docketed was really worth, as against the number on your letterhead. On the example firm, the letterhead says $225.00 and the effective rate is $170.45, which is 75.8% of it. Measured against every hour the year had rather than every hour docketed, it is $93.75.

The example firm, joint by joint

We print each fraction with its own top and bottom line, in your figures. That isn't decoration. It's the single most common way the spreadsheet version goes wrong, and it's free to fix.

One thing we won't do is add the three leaks into a single number and call it what you lost. The first of them is capacity you never docketed, and nobody dockets everything. It is a ceiling, not a loss.

The share of the work you did that actually made it onto a bill.

Say you docketed 1,870 hours and 1,700 of them reached an invoice. Your realization rate is 1,700 over 1,870, or 90.9%. The 170 hours in between are write-downs, work you did, recorded, and then decided not to charge for.

Two things make this word slippery, and both of them are why we print the fraction.

The first is that realization can be measured in hours or in dollars, and they're not the same number the moment your invoices go out at anything other than your standard rate. In hours, it asks what share of your docket got billed. In dollars, it asks what share of your docket's value got billed, which also catches the discount you gave. We measure hours, we say so, and the dollar reading appears as a second line the moment you type in what you actually invoiced. On the example firm, entering $350,000.00 against $382,500.00 of invoiced hours leaves realization in hours at 90.9% and drops realization in dollars to 83.2%.

The second is that plenty of published explanations use "realization" for the collection rate instead. One time-tracking vendor's realization-rate page defines it in its own FAQ as revenue collected over revenue billed, which is the collection rate, while linking to a separate collection-rate tool on the same site. Another names it two different ways on one page. If a number arrives without its fraction attached, it isn't telling you anything.

This is for a practice that bills by time. A lawyer or licensee with one or two associates. A small CPA firm, a bookkeeping practice, a payroll or tax preparation business. Anyone whose year is a docket, an invoice run and a deposit, in that order.

It isn't for a contingency practice, and that isn't a limitation we're apologizing for. If the fee is a share of a recovery, the chain measured here does not exist in your files. You have a different economics and it deserves a different tool.

It's also not a per-matter tool. This is the firm's whole period, not one file. If the question is whether a particular matter paid for itself, that's a different calculation with different inputs.

And a plain word about what the numbers are for. Raising your realization rate means billing the work you actually did, on time, before the client has forgotten what it was for. It does not mean billing more than you did. Hours have to be worked, and recorded when they are worked. If a page of arithmetic ever reads as an argument for anything else, close it. In Ontario, the Law Society's rule 3.6-1 puts it plainly: a lawyer shall not charge or accept any amount for a fee or disbursement "unless it is fair and reasonable and has been disclosed in a timely fashion". If you practise outside Ontario, check the fee rules your own regulator publishes.

There are only four levers in the whole chain, and one of them isn't really a lever at all.

Utilization moves when the day changes shape. That is slow, and mostly not an arithmetic problem. Realization moves when the gap between doing the work and sending the bill gets shorter, and most write-downs aren't decisions, they're what happens to a time entry reconstructed three weeks late. Collection moves when someone owns the follow-up, which in a small practice usually means nobody does. And the rate moves when you decide it moves, which is the one we deliberately have no opinion about.

One Canadian footnote worth knowing before you reach for late-payment interest as the answer to a collection problem. In Ontario, rule 3.6-1.1 says a lawyer shall not charge a client interest on an overdue account "save as permitted by the Solicitors Act or as otherwise permitted by law". Check your own province's rule before the invoice goes out, not after.

The lever worth pulling first is usually the biggest spill in the funnel, and it is rarely the one that felt worst.
