Budgets and net proceeds.
Cost per attendee, break-even, and reporting net to the board.
Three numbers the board actually reads.
A gala budget is a normal event budget with three extra lines the board will go straight to: gross revenue, total cost, and net proceeds.
If you have ever presented a beautifully itemized event budget and watched a treasurer flip to the last page, you know why.
Building the cost side.
Cost lines for a hotel gala fall into fixed and per-head.
Fixed costs do not change if you sell 150 or 200 seats: room rental (often waived against an food and beverage minimum), production, entertainment, planner fee, design, printing, insurance, mobile bidding software.
Cost per attendee and break-even.
Cost per attendee is total cost divided by seats.
It tells you what a ticket must cost just to stand still.
Worked example: the Harbour Gala net.
Gross revenue from lesson 2 was roughly 95,000 dollars in tables and sponsorship.
Add the paddle raise, which the foundation budgeted conservatively at 40,000 dollars based on last year, a live auction at 12,000 dollars for two lots, and a silent auction at 8,000. dollars
Numbers to remember.
Add it as a separate line on every vendor estimate.
Hotel service charge is commonly 18 percent on food and beverage, and it is taxable. Ask whether it reaches staff; if it does not, budget a separate gratuity.
That is the lesson. The worksheet and the quiz are just below this video.
Three numbers the board actually reads
A gala budget is a normal event budget with three extra lines the board will go straight to: gross revenue, total cost, and net proceeds. If you have ever presented a beautifully itemized event budget and watched a treasurer flip to the last page, you know why. Build the document so those three numbers are at the top, with the detail underneath.
The fourth number people ask about is cost per attendee, and the fifth is break-even. Have both ready before the first committee meeting, because the committee will ask what the event has to sell before it makes anything.
Building the cost side
Cost lines for a hotel gala fall into fixed and per-head. Fixed costs do not change if you sell 150 or 200 seats: room rental (often waived against an F&B minimum), production, entertainment, planner fee, design, printing, insurance, mobile bidding software. Per-head costs move with the count: food and beverage per plate, service charge and HST on that, favours, name cards.

| Line | Type | Harbour Gala estimate |
|---|---|---|
| Hotel food and beverage, 200 plates (F&B minimum $18,000) | Per-head, with a minimum | $18,000 before 18% service charge and 13% HST; about $24,000 all-in |
| Audio, lighting, screens, technician | Fixed | Typical GTA range, 2026: uplighting 20 fixtures $600 to $1,200; full AV with screens and a tech is a separate quote, usually several thousand |
| Mentalist, 25-minute set | Fixed | Typical GTA range, 2026: $1,500 to $5,000 |
| Two strolling magicians, cocktails plus the pre-dinner gap | Fixed | Typical GTA range, 2026: $600 to $1,500 each for 2 hours |
| Auctioneer | Fixed | Quote; some charge a flat fee, some a percentage of the live auction |
| Planner flat fee | Fixed | $4,500 |
| Design, print, signage, mobile bidding licence, insurance | Fixed | Quote; one-day liability cover typically $150 to $400 |
Two habits save you at reconciliation. Enter every vendor quote before HST and add HST as its own line, because vendors quote before tax and the board compares your estimate to the invoice. And treat the hotel service charge as taxable, because it is; the event budget calculator has a field for exactly this.
Cost per attendee and break-even
Cost per attendee is total cost divided by seats. It tells you what a ticket must cost just to stand still. For the Harbour Gala, if total cost lands around $40,000 across 200 seats, cost per attendee is $200. A $300 ticket then contributes $100 to the cause; a $250 ticket contributes $50. That is why ticket sales alone never make a gala.
Break-even is the revenue needed to cover total cost. Work it as a short procedure:
- Add up the fixed costs. Say $22,000 (production, entertainment, auctioneer, planner, print, software, insurance).
- Work out the all-in per-head cost from the hotel. The $18,000 minimum across 200 plates is $90 per plate before service and tax, or roughly $120 all-in.
- Decide the average revenue per seat. If sponsorship and tables average $475 a seat ($95,000 across 200 seats), contribution per seat is $475 minus $120, or $355.
- Divide fixed costs by contribution per seat: $22,000 divided by $355 is about 62 seats. Everything after the 62nd seat is net.
Note the F&B minimum changes this. The hotel will charge $18,000 whether you serve 150 or 200, so below 150 seats the per-head cost stops falling and the minimum behaves like a fixed cost. Run the calculator both ways.
Worked example: the Harbour Gala net
Gross revenue from lesson 2 was roughly $95,000 in tables and sponsorship. Add the paddle raise, which the foundation budgeted conservatively at $40,000 based on last year, a live auction at $12,000 for two lots, and a silent auction at $8,000. Gross for the night comes to about $155,000.

Total cost: hotel $24,000 all-in, entertainment and auctioneer roughly $8,000, AV roughly $6,000, planner $4,500, print, design, software, insurance and contingency roughly $5,000. Call it $47,500. Net proceeds to the foundation: about $107,500, or 69 cents of every gross dollar.
The board report shows those three numbers first. Then a short table of revenue by engine (sponsorship, tickets, paddle, live, silent). Then cost by category. Then a two-line note on what changed from budget: the entertainment sponsor covered the mentalist and magicians in full, and the hotel came in $1,100 over because dinner ran 25 minutes long and bar staff went into overtime. That last line is the one the board remembers, and it is the one that fixes next year’s run of show.
Use the event budget sheet for the working file and the event ROI calculator for the net-to-gross ratio the board will compare to other events.
Numbers to remember
- HST is 13%. Add it as a separate line on every vendor estimate.
- Hotel service charge is commonly 18% on food and beverage, and it is taxable. Ask whether it reaches staff; if it does not, budget a separate gratuity.
- A $300 ticket against a $200 cost per attendee nets $100. Tickets fill the room; sponsors fund the cause.
- Below the F&B minimum your per-plate cost stops falling. Know the seat count where that happens.
- Net-to-gross is the ratio boards compare across events. Put it in the report whether or not they ask.
- Contingency of roughly 5 to 10 percent of cost is normal for a first-year event; a repeat event with clean history can run tighter.
