Labor, mobile bar, setup, and tip — priced by your guest count and bar style
| Guests | Beer & wine only | Beer, wine + signature | Full cocktail bar |
|---|---|---|---|
| 25 | 1 | 1 | 1 |
| 50 | 1 | 1 | 1 |
| 75 | 1 | 2 | 2 |
| 100 | 2 | 2 | 2 |
| 150 | 2 | 3 | 3 |
| 200 | 3 | 4 | 4 |
Counts follow the staffing rule of thumb of one bartender per 50-75 guests (Premier Staff, Insurance Canopy): one per 75 when guests open cans and bottles themselves, one per 50 when every drink is mixed. Peak-hour bursts — the 30 minutes after the toast — are what the extra bartender is really for.
| Line | Typical | Range | Notes |
|---|---|---|---|
| Bartender labor | $50/hr | $30-$70/hr | Agency professionals; Thumbtack's band runs $40-$60 |
| Two-hour minimum | — | Standard | Short events still bill two hours of service |
| Setup/teardown | 0.5 hr | 0-1 hr | Billed at the same rate, per bartender |
| Mobile bar package | $500 | $300-$800 | Bar, ice, mixers, garnish, cups — you supply alcohol |
| Gratuity | 18% | 15-20% | Of labor, unless a tip jar or auto service charge applies |
| Flat event fee alternative | — | $200-$700 | Some staffing companies bill a flat fee instead of hourly |
What's not here: the alcohol itself. For bottles and cans, use the wedding alcohol calculator — it converts guests and hours into actual bottles to buy. This tool prices the people and equipment line only.
Bartender pricing is a headcount-times-hours business with a staffing rule stapled to it. This calculator sizes the crew from your guest count and bar style, bills their hours plus setup, and layers on the two add-ons that surprise hosts: the mobile bar package and gratuity.
Bartenders = guests ÷ 50 for a full cocktail bar, ÷ 60 with a signature cocktail, ÷ 75 for beer and wine only, always rounded up. Billed hours = service hours (two-hour minimum) + setup hours. Labor = bartenders × billed hours × hourly rate. Total = labor + mobile bar package (if the venue has no bar) + gratuity percentage on labor. The default $50 rate sits mid-band of the national $30-$70 range.
Set guests and hours first, then pick the bar style honestly — the difference between "beer and wine" and "full bar" is often a second bartender, which is the single biggest line. If your venue or caterer provides the physical bar, untick the mobile bar package. Enter the actual quoted rate if you have one; $40-$60 is the common Thumbtack band, and major-metro specialists quote above it.
Wedding, 100 guests, full bar, 4 hours + 0.5 setup: 100 ÷ 50 = 2 bartenders, each billing 4.5 hours. At $50 an hour, labor = 2 × 4.5 × $50 = $450. No bar at the venue, so add the mobile bar package at $500. Gratuity at 18% of labor = $81. Typical total: $1,031, with the range running $619-$1,543. That lands inside Insurance Canopy's published $480-$1,200 band for 100-150-guest events where you supply the alcohol.
Casual party, 40 guests, beer and wine, 3 hours: 40 ÷ 75 = 1 bartender. Labor = 3.5 × $50 = $175 typical ($105-$245 range), package skipped because the kitchen island is the bar, tip jar instead of prepaid gratuity. One invoice line, under $200 — which is why the "should we just hire someone?" question usually answers itself.
Bartenders charge $30-$70 an hour, with $50 typical for a professional through a staffing agency or mobile bar company. A three-hour party for 40 guests needs one bartender, so labor runs about $175 (range $105-$245). Add a mobile bar package at $300-$800 if your venue has no bar, and gratuity at 15-20% if it's not already on the invoice.
Two for a full cocktail bar, one for a beer-and-wine-only bar at that count. The staffing rule of thumb is one bartender per 50-75 guests — closer to one per 50 when the menu includes mixed drinks, one per 75 when it's open cans and bottles. For 150 guests on a full bar, plan on three.
A mobile bar package (typically $300-$800) brings the physical bar, ice, mixers, garnishes, cups, and sometimes small equipment — you supply the alcohol, which is what keeps it cheaper than a full open-bar package. Labor may be bundled or billed separately at $30-$70 an hour per bartender, so compare quotes on the all-in number, not the headline rate.
Usually yes — expect 30 minutes to an hour of setup and breakdown billed at the same hourly rate, and a two-hour minimum on the event itself. A four-hour reception realistically bills 4.5 hours per bartender. Some agencies fold it into a flat event fee of $200-$700 instead; both structures are normal.
Yes — 15-20% of the labor bill is standard when you're paying the bartender directly, and many contracts auto-add it as a service charge (read the line items before double-tipping). The tip jar is the other accepted norm at casual events; $1-$2 a drink adds up to roughly the same place, and hosts who want no jar in photos can pre-pay the gratuity instead.
Often yes. Many states require alcohol server training or licensing, venues commonly demand proof of liquor liability insurance, and caterers may insist on TIPS-certified staff. That's a real reason to hire through a staffing agency or mobile bar company rather than a talented friend: their certification and insurance are part of what the hourly rate buys. Requirements vary by state and venue, so ask yours directly.
