Separate a cash win from a worthwhile workday.
The calculations
Revenue = session price × booked slots. Payment fees = revenue × percentage rate + booked slots × payments per client × flat fee.
Cash surplus = revenue − setup − location − other fixed costs − (bookings × variable cost) − payment fees. This is before owner labor and income taxes.
Owner hours = available slots × (shooting + buffer minutes) ÷ 60 + bookings × editing minutes ÷ 60 + other owner hours. Unsold slots still reserve time. If you actually shorten the event, reduce the available slots to match.
Profit after owner labor = cash surplus − (owner hours × hourly value)
The hourly result divides cash surplus by all owner hours. It shows what remains for your time before taxes and reserves. It is not employee pay or personal take-home income.
Break-even, with the important costs included
Cash contribution per booking = price × (1 − fee rate) − variable cost − payments per client × flat fee.
Cash break-even is fixed cash costs ÷ cash contribution, rounded up to whole bookings. A nonpositive contribution cannot cover positive fixed costs.
Labor-adjusted contribution also subtracts editing hours per booking × hourly value. For labor-adjusted break-even, add the value of the reserved event hours and other fixed owner hours to fixed cash costs, then divide by labor-adjusted contribution and round up.
If break-even exceeds available slots, a sellout cannot solve this event’s economics. If all fixed costs are zero, zero bookings is technically break-even; a negative contribution still means each additional booking loses money.
A hypothetical 12-slot mini-session day
At the default 10 bookings × $250, revenue is $2,500. Fixed expenses total $650, client costs total $250, and 3% plus two $0.30 transactions per client produces $81 in fees. Cash surplus is $1,519.
The event reserves 6 hours, editing takes 7.5 hours, and other work takes 5 hours: 18.5 owner hours. At $40 per hour, that is $740 of labor value and $779 left after owner labor. Cash break-even is 3 bookings; covering owner labor requires 6. No bookings would still cost $650 in cash and commit $440 of owner time.
Choose the event you can deliver well.
These estimates assume one fixed price, the same deliverables for every booking, and all expected clients paying in full. Add costs for reshoots, travel, products, assistants, and weather contingencies where relevant. Refunds, sales tax collected, income tax, incremental upsells, and timing of deposits are not modeled. Allocate a fair share of ongoing overhead in “other fixed” if you want the event to support the wider business.
