Utilisation and realisation on five consultants: the whole arithmetic on one page

The complete utilisation and realisation calculation on five consultants, small enough to check by hand: available and chargeable hours from the roster and time entries, utilisation, fees billed on each consultant's hours from bills allocated by engagement, chargeable hours at standard rate, realisation, the two fixed-fee engagements that have overrun and the share of each consultant's hours on them, the four quadrants, and the identity that hours and fees sum to the firm's, so a reader can reproduce every figure and then run it on their own practice management exports.

The short answerFive consultants, one quarter, 480 available hours each. Utilisation is chargeable hours over available. Realisation is the fees billed on the consultant's hours over those hours at the standard rate of $200, with each engagement's billed fees allocated to consultants by their share of its hours. Two fixed-fee engagements have run to 160 and 164 percent of budget and bill their fixed amount; the consultants on them realise around 60 percent. The most utilised consultant, at 94 percent, realises 51; the least utilised, at 58, realises 95. Hours sum to the firm's chargeable hours and fees to the firm's billed fees. Every number can be reproduced by hand.

Utilisation and realisation are two ratios per consultant from the same time entries, and on five consultants both can be worked by hand. This page works the hours, the fee allocation, both ratios, the overrun engagements, the quadrants and the identity.

The engagements

Standard rate: $200 an hour.

Engagement Fee type Budget hours Hours to date Billed Realised rate per hour
E-1 Fixed, $80,000 400 640 $80,000 $125
E-2 Fixed, $50,000 250 410 $50,000 $122

E-4 Time and materials, 10% discount 350 $63,000 $180
Total 2,000 $313,000

Firm chargeable hours this quarter: 2,000. Billed fees: $313,000.

The consultants' hours

Available: 480 each.

Consultant E-1 E-2 E-3 E-4 Chargeable Utilisation
A 260 100 90 0 450 94%
B 0 0 260 100 360 75%
C 180 110 0 0 290 60%
D 0 0 250 30 280 58%
E 200 200 0 220 620 129%: over available; overtime
Total 640 410 600 350 2,000

Hours sum to 2,000. Identity holds.

Fees allocated to consultants

Consultant's fees on an engagement = engagement billed × consultant's hours ÷ engagement hours

Consultant Fees Hours at standard Realisation
A 260×125 + 100×122 + 90×200 = 32,500 + 12,200 + 18,000 = $62,700 $90,000 70%
B 260×200 + 100×180 = 52,000 + 18,000 = $70,000 $72,000 97%
C 180×125 + 110×122 = 22,500 + 13,420 = $35,920 $58,000 62%
D 250×200 + 30×180 = 50,000 + 5,400 = $55,400 $56,000 99%
E 200×125 + 200×122 + 220×180 = 25,000 + 24,400 + 39,600 = $89,000 $124,000 72%
Total $313,020 ≈ $313,000 $400,000 78%

Fees sum to the billed total within rounding. Identity holds.

The quadrants

Norm: utilisation 72 percent, realisation 88 percent.

Consultant Utilisation Realisation Quadrant
A 94% 70% Busy, unprofitable: 80% of hours on overrun fixed fees
B 75% 97% Busy, profitable
C 60% 62% Underused, discounted: all hours on overruns
D 58% 99% Underused, well billed: bench time; sold work profitable
E 129% 72% Overloaded, unprofitable: overtime on overruns

The source

Engagement Overrun Hours over budget Cost of overrun at standard
E-1 160% 240 $48,000
E-2 164% 160 $32,000

Eighty thousand dollars of hours the firm delivered and could not bill, carried by A, C and E.

Where it goes wrong, even at five

Utilisation as the measure. A is the star; E is the hero; D is on the bench.

Fees not allocated to hours. Realisation at engagement level only; nobody knows A carried it.

Fixed fees excluded. Realisation reads 100 percent everywhere except E-4's discount.

E's 129 percent unread. Overtime on work that does not bill.

From five to five hundred

The same allocation per consultant per engagement, the same two ratios, per practice, with the norm from the firm's own attainers. Covirage runs it on the time entries, bills and roster every month. The utilisation against realisation guide covers the measure, and the leverage drift guide covers the other reason a fixed fee overruns.

Questions people ask

How are fees allocated to consultants?

Per engagement: the engagement's billed fees times the consultant's share of the engagement's hours. A fixed-fee engagement billed at $80,000 with 640 hours worked realises $125 an hour, and every consultant's hours on it carry that rate. Time-and-materials engagements billed at the standard rate realise 100 percent, less any discount.

Why is the 94 percent consultant the least profitable?

Because 80 percent of their hours are on the two overrun fixed fees. Every extra hour there is chargeable and none of it bills. Utilisation counts the hour; realisation says the firm paid for it.

What is the norm?

The firm's own attainers: consultants whose engagements were profitable over the year, here at about 72 percent utilisation and 88 percent realisation. The four quadrants are read against those two figures.
