Selling flex memberships against a fixed number of hot desks is a balancing act. Sell too few and desks sit empty; sell too many and a member walks in on a Tuesday morning to find nothing free, which is the fastest way to lose them. Most operators guess at a member to desk ratio, but the right number depends on how often your members actually show up and how lumpy your week is.

This calculator turns your member count, average visits per week and open days into expected desk demand. It estimates average daily occupancy, then applies the share of visits that land on your busiest day to get peak occupancy and peak utilization against the desks you have. It also works backwards to tell you the largest membership your current desks can carry while staying under your target utilization. It only uses the numbers you enter; there are no hidden industry averages.

How to use this tool

  1. Enter the number of flex or hot desk members and how often the average member comes in each week, ideally from check-in data.
  2. Add your open days, hot desk count, the share of weekly visits that land on your busiest day, and the utilization you are comfortable with.
  3. Read the peak day occupancy and utilization, then use the max members figure to decide whether to keep selling memberships or add desks.

What the math assumes

  • Every member visit occupies one hot desk for the whole day; half day visits are not modeled separately.
  • The busiest day carries the share of weekly visits you enter, and it is never treated as lower than an evenly spread day.
  • Only shared hot desks and the members who use them are counted; dedicated desks, private offices and their members are excluded.
  • Max members is calculated on the busiest day at your target utilization, so it is a conservative ceiling rather than an average.
  • Walk-in day passes and guests are not included unless you add them to the member count.

Frequently asked questions

What is a typical member to hot desk ratio for a coworking space?

There is no single right ratio, because it depends entirely on how often your members visit. This calculator derives the ratio from your own visit data instead of applying a rule of thumb, so check your check-in logs for a real visits per week figure.

How do I find my peak day share?

Look at check-ins over the last four to eight weeks and divide the busiest weekday's visits by the weekly total. Many spaces see midweek peaks; if your days are evenly spread, use 100 divided by your open days.

What should I do if the verdict says over capacity?

Either add desks, pause new flex sign-ups, or use booking rules such as a daily booking cap or advance booking limits to spread visits away from the peak day. Rerun the calculator with the new numbers to see the effect.
