Too few promoters: you give away contacts. Too many: you give away budget. On an activation with 10'000 samples and 5 locations, a miscalculation of 2 people can cost CHF 3'000 to 6'000. In both directions. Here's the planning method we've used at PROMOKANT for 20 years.

The base formula: how to calculate team size
The base formula for promoter headcount: target contacts per day divided by contacts per hour per promoter divided by shift hours per day. Depending on activation type, one promoter handles 40 to 120 contacts per hour. For an activation with 3'000 contacts per day, 8 hours and 80 contacts per hour, you need 5 promoters.
The formula in detail:
Promoters = target contacts / (contacts per hour x shift hours)
Sounds simple. It is, if you use the right value for "contacts per hour". And that's exactly where it gets interesting, because that value varies massively by activation type, location and time of day.
For fast product sampling on the street, a good promoter handles 100 to 120 contacts per hour. For a tasting with conversation it's 30 to 50. For a complex product demonstration at a roadshow, maybe 15 to 25.
The mistake most people make: they take the average and extrapolate linearly. But reality isn't linear. A promoter working 8 hours straight isn't as efficient in hour 7 as in hour 2. Plan a 15 to 20% efficiency discount for shifts over 6 hours.
Benchmarks by activation type
These benchmarks are based on our data from over 200 projects per year. They are averages. Your specific case may differ.
| Activation type | Contacts/h per promoter | Min. promoters per location | Recommendation |
|---|---|---|---|
| Street sampling (flyering) | 100-150 | 1 | 2 per hotspot |
| Product sampling with conversation | 60-100 | 1 | 2 per location |
| In-store tasting | 30-50 | 1 | 2 at high traffic |
| Roadshow / event stand | 15-30 | 3 | 3-5 per stand |
| Door-to-Door | 8-15 | 1 | Teams of 2 |
| Merchandising / POS | n/a (stores/h) | 1 | 4-6 stores per day |
Important: "contacts per hour" means qualified contacts. People who took the sample, tasted the product or had a conversation. Not people who walked past.
5 factors that change your calculation
1. Location traffic. At Zurich HB 20'000 people pass per hour. At Aarau station 3'000. Traffic dictates how many contacts are even possible. At a low-traffic location, a third promoter brings nothing because there simply aren't enough passers-by.
2. Time of day. Mornings (7-9 a.m.) and evenings (5-7 p.m.) are peak at the station. Saturday 10 a.m.-2 p.m. is peak downtown. Noon (12-1 p.m.) is peak in office districts. Plan your team along these peaks: more people at peak, fewer in between.
3. Weather. In rain, outdoor traffic drops by 30 to 50%. With uncertain weather plan 1 to 2 promoters fewer or move them to covered locations. Indoor activations are weather-independent.
4. Product complexity. An energy drink is handed over in 5 seconds. A new skincare product needs 2 minutes of explanation. The longer the conversation, the fewer contacts per hour, the more promoters you need.
5. Activation goal. Is distributing the product enough (awareness)? Or do you want leads (sign-ups, QR scans)? Lead generation takes 3 to 5 times longer than pure sampling. Adjust the calculation accordingly.
Worked example: 3-day sampling in Zurich
Brief: a beverage producer wants to sample a new product in Zurich. 15'000 samples, 3 days, 3 locations (HB, Bellevue, Langstrasse).
Calculation:
- 15'000 samples / 3 days = 5'000 samples per day
- 5'000 samples / 3 locations = 1'667 samples per location per day
- Shift time: 8 hours (10 a.m.-6 p.m.)
- Contacts per hour per promoter: 80 (product sampling with conversation, outdoor)
- 1'667 / (80 x 8) = 2.6 promoters per location
- Round up: 3 promoters per location
- Total: 3 x 3 = 9 promoters
Cost calculation:
- 9 promoters x 3 days x CHF 380 (day rate) = CHF 10'260
- 1 team lead x 3 days x CHF 480 = CHF 1'440
- Material, logistics, cooling: CHF 2'500
- Samples (15'000 x CHF 0.80): CHF 12'000
- Total: CHF 26'200
- Cost per Contact: CHF 1.75
With real-time reporting with kyoX you track actual contacts live and can adjust the distribution on day two if one location over- or underperforms.
Quality beats quantity
The temptation is big: take cheap people, take a lot of them. Doesn't work. An experienced promoter at CHF 35 per hour generates 40 to 60% more qualified contacts than a newcomer at CHF 27 per hour. Run the maths: the more expensive promoter costs you CHF 3.00 per contact, the cheap one CHF 3.80. Because they're slower, lose more contacts and come across less convincingly.
At PROMOKANT we rely on a fixed pool of over 600 trained promoters. Each has completed at least 5 shifts before going into a demanding project. That makes planning more predictable and results more consistent.
Our advice: invest the budget in fewer but better people. Three strong promoters beat five mediocre ones. Always.
Plan reserves and absences
Reality: on every activation, someone drops out. Illness, public transport delays, personal reasons. Plan for a drop-out rate of 5 to 10%. With 10 promoters that means: 1 reserve on standby.
For multi-day activations or roadshows you need more reserve. At 5 days or longer: 15% reserve. That doesn't mean you pay 15% more. Reserves are only activated if someone drops out. But the people must be briefed and ready to go.
Checklist for staff planning:
- Calculate base needs (formula above)
- Apply efficiency discount (15-20% for long shifts)
- Account for peak times (more staff at peak)
- Plan reserves (5-10% for short shifts, 15% for multi-day activations)
- Don't forget the team lead (1 per 5-8 promoters)
- Define experience levels (senior for complex products, standard for simple sampling)
