Which indoor rowing studio expenses stay fixed and which move with sales?

Cost classification

Break-even gets unreliable when fixed payroll, rent, and usage-linked items are mixed together. Bad labels make the studio look safer than it is.

Expense	Cost	Break-Even Treatment	Common Mistake
Studio Rent	Fixed	Use $8,000 per month across the planning range.	Tying rent to class fill rate.
Studio Manager	Fixed	Use $5,000 per month from Month 1 through Month 60.	Treating manager pay as per-class labor.
Lead Instructor	Semi-fixed	Use $4,167 per month, then step up only if the schedule expands.	Making the full salary vary with attendance.
Part-time Instructors	Semi-fixed	Use $5,833 per month in the first year, with planned FTE increases later.	Modeling all instructor pay as purely variable.
Credit Card Processing Fees	Variable	Apply 2.5% of revenue in the first year.	Forgetting fees rise with membership sales.
Digital Marketing Spend	Variable	Apply 5.0% of revenue in the first year if modeled as revenue-based spend.	Locking ad spend as fixed while revenue scales.
Utilities	Semi-variable	Start with $1,200 per month and review usage as class volume grows.	Assuming utilities never move with studio traffic.
Cleaning Staff	Semi-variable	Use $1,042 per month in the first year, with hours rising as traffic increases.	Ignoring added cleaning needs at higher occupancy.

How does break-even shift from a lean opening to a full rowing studio?

Scenario table

As membership and occupancy rise, revenue spreads the fixed rent and payroll across more sales. The lean case still runs a loss, the base case sits near break-even, and the full case creates a clear cushion.

Planning cases only: these figures are model-based assumptions, not guarantees.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean opening case	$22,350	$2,235	$29,442	90.0%	-$9,327	Fixed costs outrun sales, so break-even is not reached.
Base case	$35,000	$3,220	$30,900	90.8%	$880	Near break-even, so small swings in enrollment matter.
Full studio case	$71,700	$4,935	$38,817	93.1%	$27,948	Strong cushion; fixed costs are well absorbed.

What breaks first if bookings, rent, or instructor pay slip?

Stress test

Year 1 revenue of $22,350 is already below the $32,713 break-even line, so the studio starts with a $10,363 gap. A 10% sales miss, higher rent or wages, and fee creep can widen that hole fast.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$32,713	$10,363 gap	Year 1 sales sit below break-even.
Revenue shortfall	Monthly sales fall 10% to $20,115.	$32,713	$12,598 gap	A small booking miss widens the hole.
Fixed-cost increase	Studio overhead rises 10% to $32,386.	$35,984	$13,634 gap	Higher rent or staffing pushes break-even up fast.
Margin pressure	Variable expenses rise to 15% of revenue, cutting margin to 85%.	$34,637	$12,287 gap	Fee creep and discounting eat the cushion.
Combined pressure	Sales fall 10%, overhead rises 10%, and variable expenses reach 15% of revenue.	$38,101	$17,986 gap	This mix can burn cash very quickly.

Can this indoor rowing studio clear break-even before you sign the lease?

Founder checklist

Do not lock the lease or buy the machines until pre-sales can get close to the model’s $32,713 monthly break-even target. Year 1’s 150 members only model about $22,350 in monthly revenue, so the opening plan still has a gap.

1Pre-sales$32.7K/mo

Verify signed pre-sales can get near the $32,713 monthly break-even target before you commit to the lease, because Year 1’s 150 members model only about $22,350 in monthly revenue.

2Startup Capex$160K

Confirm you can fund the $60,000 rowing machines and the $100,000 build-out without touching operating cash, because that spend hits before memberships scale.

3Rent Load$8,000/mo

Keep rent near the modeled $8,000 a month unless pricing can support more, because a higher base cost makes the break-even gap much harder to close.

4Variable Load10.0%

Check that processing, amenities, retail goods, and marketing stay near the Year 1 rates, because the 10.0% variable load is what protects contribution after each class sale.

5Member Ramp225 members

Test whether the site can reach Year 2’s 225 members and about $35,000 in monthly revenue with the instructor coverage you can actually staff.

6Cash Cushion$807K

Hold cash for the model’s $807,000 minimum cash need, because the tightest point lands in Month 2 and a thin reserve can stall the launch.
