How Many Hours Does an Associate Consultant Work?

How many hours a week does an associate consultant work?

A staffed associate consultant at McKinsey, BCG or Bain typically works 55-70 hours a week, most of it Monday to Thursday. Between projects or during training the week drops to about 40 hours. Deadline weeks, due diligences and final presentations can push toward 80. Averaged over a year, most consultants land in the mid-to-high 50s.

When I first wrote about this in 2011, I shared a Bain associate consultant's self-tracked chart that averaged about 56 hours a week, with quiet weeks near 40 and peaks near 80. Current reports from former MBB consultants still describe a 50-60 hour norm, so the shape of the job has stayed remarkably stable.

Hours by project phase

Weekly hours depend more on where you are in the project cycle than on which firm you joined. The table gives typical ranges based on consultant reports; your own weeks will vary with the client and the manager.

Short, intense projects drive the extremes. A three-week due diligence for a private equity fund runs much hotter than a six-month strategy engagement for a long-standing client.

What a typical day looks like

Daily hours usually run 8-12. A normal client-site day might start at 8:30 with a team check-in, move through client interviews and analysis, include a problem-solving session with the manager in the late afternoon, and end with an hour of slide work after dinner. Days of 16 hours or more happen, but consultants describe them as rare and tied to specific deadlines.

Travel models: Monday to Thursday on site

Travel adds hours that do not show up as billable work. The classic consulting week has you fly or drive to the client on Monday morning, stay in a hotel until Thursday evening and spend Friday in your home office. After the pandemic most MBB offices returned to this pattern, often with more flexibility on how many days a team needs to be on site.

The firms staff differently:

• Bain mostly staffs consultants on local or regional clients, which tends to mean shorter trips.
• McKinsey uses a regional or global model, so consultants can be staffed further from home.
• BCG sits between the two, varying by office and practice.

Your office matters as much as your firm. A consultant in a large hub with many local clients travels less than a colleague in a smaller office serving clients across a region.

Firm policies that protect your time

All three firms have built policies to make the hours sustainable, though enforcement depends on the team.

1. Protected weekends. Weekend work is treated as an exception for urgent situations.
2. Respected vacation. Booked vacation is almost always honored; cancelling it is a last resort.
3. Team norms. Many teams agree a set end time or one work-free evening a week at the project kickoff.
4. Leave options. More senior consultants can often take unpaid leave or longer breaks, depending on office policy.

The best-documented example is BCG's Predictability, Teaming and Open Communication program, studied by Harvard professor Leslie Perlow and described in 2012. Teams that committed to one planned night off per week saw their average workweek fall from 64.5 to 57.7 hours, with client satisfaction equal to or better than on comparable projects. The lesson for new consultants is practical: raise your workload early and openly with your manager.

How to keep the hours manageable

The consultants I coached who handled the hours best followed a few habits:

• Agree on deadlines and the definition of "done" with your manager every Monday.
• Protect sleep before big presentations; tired analysts make spreadsheet errors that cost more time.
• Build the case interview math speed you trained for interviews into daily work, because quick estimates save hours of unnecessary modeling.
• Use beach time to recover, and to learn something that makes the next project faster.

Stephan's note: The hours are real, and the pay reflects them. What surprised the people I coached was how much more the predictability mattered than the total. Sixty hours you can plan around feels very different from fifty hours that can blow up any evening.

Is the trade-off worth it?

For most people who join, yes, for at least the first two or three years: the learning curve, the consulting salary and the exit options compensate for the workload. If you are preparing for interviews, my book Cracking the Case covers how to answer the personal-fit questions about why you want this lifestyle.
