Opening a sim racing centre: the numbers before the dream

A sim racing centre is a throughput business wearing a motorsport costume. Everything that decides whether it works is a number you can calculate before signing a lease.

The throughput arithmetic

Start from the slot, not the rig. A 15 minute slot means 4 drivers per rig per hour, so a floor of 6 rigs has a theoretical ceiling of 24 drivers an hour and 240 across a 10 hour day. That number is the entire business.

Then apply an honest utilisation. Weekday afternoons rarely exceed 20 per cent and weekend evenings can reach 90, so a realistic annual average sits somewhere between 30 and 40 per cent. At 35 per cent, those 240 daily slots become about 84.

And check whether the price supports the rent. 84 slots a day at a given price is the revenue line, and every fixed cost below has to fit inside it before a single salary is paid.

Planning figures for a six station floor
Item	Figure
Slot length	15 minutes, so 4 drivers per rig per hour
Theoretical ceiling	24 drivers an hour, 240 in a 10 hour day
Realistic annual utilisation	30 to 40 per cent
Slots at 35 per cent utilisation	about 84 a day
Floor area	about 6 square metres per station, 36 for six
Power per station	plan around 700 watts
Power for six stations	roughly 4,200 watts
Capacity of one 16 ampere circuit at 230 volts	about 3,680 watts
Recommended machine	6 processor cores, 16 GB memory, 8 GB video memory
Storage per station	225 GB for the full library, 1.35 TB for six

Space and electricity, before the interior design

Each rig needs its own floor area plus room to get in and out and a walkway behind. Planning at roughly 6 square metres per station including circulation is a workable starting figure, so 6 rigs consume about 36 square metres before reception, seating or storage.

The workplace regulation requires an adequate floor area and an adequate clear height depending on the size of the room, without naming a figure in the regulation itself, and it requires emergency exit doors to open outwards. Both are checks to make before the lease rather than after the fit out.

The electricity is the surprise. Plan around 700 watts per station for a machine driving three screens under load, and 6 stations reach roughly 4,200 watts. A single 16 ampere circuit at 230 volts carries about 3,680 watts, so 6 rigs need at least 2 dedicated circuits before lighting and ventilation.

The hardware bill people underestimate

The specification is not negotiable downwards. The simulator's own recommendation is 6 processor cores, 16 gigabytes of memory and 8 gigabytes of dedicated video memory, and a commercial floor cannot run at the 4 core minimum without visible stutter in front of a paying customer.

Storage multiplies. A full content library wants 225 gigabytes, so a 6 rig floor commits about 1.35 terabytes before recordings, and the 40 gigabyte minimum only covers a fraction of the cars and tracks a commercial customer expects to see.

And consumables are real. Wheels, pedals and seat upholstery under public use wear at a pace a private owner never sees, and a budget without an annual replacement line is a budget that breaks in year 2.

The costs that appear in month two

Staffing, because unsupervised rigs break and unattended customers leave. One person cannot brief, seat, restart and settle up for 24 drivers an hour, and the second member of staff is what converts a queue into a repeat visit.

Content updates and licences, which are recurring rather than one off. Every station carries its own subscription and its own content purchases, and 6 stations multiply that line by 6.

And the seasonal shape. A venue that fills in November and empties in July has 5 months of rent that the peak has to carry, and a business plan built on the good months alone is the single most common way these venues close.

Frequently asked questions

How many drivers can one rig serve in a day?

At a 15 minute slot, 4 an hour and 40 across a 10 hour day, before applying a realistic utilisation of 30 to 40 per cent.

How much power does a floor of six stations need?

Plan around 700 watts each, so roughly 4,200 watts. One 16 ampere circuit at 230 volts carries about 3,680, so at least two dedicated circuits are needed.

Can I run commercial rigs at the minimum specification?

Not sensibly. The recommendation is 6 cores and 8 GB of video memory, and the 4 core minimum stutters visibly in front of a paying customer.

What is the most common reason these venues close?

A plan built on the peak months. A venue that empties for 5 months needs the peak to carry that rent.
