Billed fees over the value of time worked at standard rates, per client or per partner. Write-downs reduce it before billing; write-offs after. Drift is realisation that fell without a rate agreement changing.
A client on an agreed 30 percent discount at 70 percent realisation is on plan. One with an agreed 8 percent at 74 percent is leaking.
Forty small write-downs on one client, each too small to notice, are one pricing relationship that drifted.
Fees billed divided by the value of time worked at standard rates, per client, matter or partner, at a fixed rate card when compared over time.
A client's matters recorded $520,000 at standard and were billed at $405,000: 78 percent, down from 91 three years ago.
Read at firm level, where one client's slide is lost in the average.
