Coliving Vacancy Cost Calculator
Empty beds don't feel expensive because nobody sends you an invoice for them. This calculator writes the invoice — per day, per void, per year — and shows what filling rooms one week faster is actually worth.
Results
- Bleeding right now
- £94/day
- Cost of current voids (at 21 days each)
- £1,966
- Annual vacancy cost (14 move-outs × 21 days)
- £9,175/yr
- The lever
- Filling each void just one week faster is worth £3,058/year. That number is the honest budget for whatever removes the delay — faster listings, a waitlist, pre-move-out marketing, better turnover scheduling.
How this is calculated
- daily cost per empty bed = monthly rent ÷ 30.44
- current bleed = empty beds × daily cost
- annual vacancy cost = move-outs/yr × avg void days × daily cost
- week-saved value = move-outs/yr × 7 × daily cost
Rent lost to an empty bed never comes back — voids are not deferred revenue, they are destroyed revenue. That is why we compute them per day, not per month. No hidden multipliers, no email wall.
Voids are destroyed revenue, not deferred revenue
A slow month in a shop can be recovered by a strong one; a bed-night that passes empty is gone permanently. That asymmetry is why vacancy deserves a daily number and a named owner. It is also why the highest-return "marketing spend" in coliving is often operational: listing the room before move-out, a maintained waitlist, same-day enquiry responses, and turnovers booked like surgeries. Our operations guide covers the turnover playbook; the marketing guide covers the demand side.
Frequently Asked Questions
How do I calculate the cost of an empty room?+
Divide the monthly rent by 30.44 (average days per month) to get the daily cost, then multiply by the days it sits empty. A £950 room costs about £31 per empty day — which is why a three-week void costs roughly £655 per event, and why operators who track voids per day behave differently from operators who notice them per month.
What is a normal void period in coliving?+
It varies by market and season, but the operational target is simple: the void should be no longer than the turnover genuinely requires — inspection, cleaning, small repairs, photos. Everything beyond that is a marketing and process delay: late listing, slow responses, no waitlist. Well-run coliving spaces re-list before move-out and regularly turn rooms in a few days.
How much should I spend to fill an empty coliving room?+
Up to the void cost it prevents. If your average void is 21 days at £31/day, each void costs ~£655 — spending £150 on targeted ads or a referral bonus to cut a week off it returns several times over. The calculator's 'week saved' figure gives you the annual version of that budget, which is the honest ceiling for retention and lead-generation investments.
Is it better to discount rent or accept a longer void?+
Run the math per case: a £50/month discount over a 12-month stay costs £600, roughly the same as a three-week void — but the discount also anchors future pricing and renewals lower, while a filled room at full rate protects the rate card. Usually the better first moves are speed (respond faster, list earlier) and added value (a free cleaning month) rather than headline-rate cuts.
Voids bigger than they should be?
Faster fills are a system, not a hope — demand engine plus turnover operations. We build both, across 15+ coliving brands.
