Which Indonesian restaurant expenses stay fixed, and which move with sales?

Cost classification

Break-even is only useful if each expense sits in the right bucket. Keep one-time buildout out of operating break-even, and tie sales-driven items to revenue or event volume.

Expense	Cost	Break-Even Treatment	Common Mistake
Commercial Kitchen Rent	Fixed	Use $4,000 per month in fixed overhead from Month 1 through Month 60.	Treating rent as lower on slow weeks, which understates the sales needed to break even.
Business Insurance	Fixed	Use $350 per month as fixed overhead across the planning range.	Spreading insurance by event and making margins look too strong at low volume.
Software Subscriptions	Fixed	Use $300 per month as recurring fixed overhead.	Putting recurring subscriptions into startup setup and leaving them out of monthly break-even.
Head Chef	Semi-fixed	Use the $75,000 annual salary at 1.0 FTE as a capacity-based staffing commitment.	Modeling the chef like hourly labor even though the salary does not move with each event.
Event Manager	Semi-fixed	Use the $60,000 annual salary adjusted by FTE as event volume requires more management capacity.	Keeping the role fixed forever and missing the jump from 0.5 FTE to 1.0 FTE.
Food Ingredients	Variable	Use 9.0% of revenue in the first year, declining to 7.0% by the mature year.	Using a flat dollar amount and hiding the food spend tied to higher sales.
Hourly Event Staff Wages	Variable	Use 5.0% of revenue in the first year, declining to 4.0% by the mature year.	Putting event labor into fixed payroll and overstating profit on small events.
Utilities	Semi-variable	Start with the $900 monthly base, then review usage as kitchen hours and event volume rise.	Treating utilities as fully fixed when longer prep days can push bills higher.

How does break-even change from lean launch to base scale to full volume for this Indonesian restaurant?

Scenario table

Ticket size rises from $75 midweek and $150 on weekends in Year 1 to $95 and $180 in Year 5, so fixed payroll gets spread over more sales and break-even gets safer. CM ratio is the share left after variable costs.

Scenario figures are planning assumptions, not guarantees; actual break-even will move with traffic, staffing, and event mix.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch case	$56.9k	$10.8k	$22.0k	81%	$24.0k	Above break-even, but weekday softness would cut the cushion fast.
Base scale case	$232.1k	$38.3k	$32.3k	83.5%	$161.4k	Comfortable cushion; higher ticket size covers the added payroll.
Full volume case	$570.4k	$79.9k	$33.9k	86%	$456.7k	Strong cushion; sales density outpaces the larger fixed cost load.

What breaks the break-even plan for this Indonesian restaurant?

Stress test

The plan stays above break-even in the base case, but a 20% sales drop, 10% higher fixed costs, or a move to 24% variable expenses quickly shrinks the cushion. The warning line is when weekly sales get close to $63k.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	Monthly revenue holds at $569k, fixed costs stay at $220k, and variable expenses stay at 19%.	$272k	$297k cushion	Solid cushion, but not endless room for misses.
Revenue shortfall	Monthly revenue drops 20% to $455k.	$272k	$183k cushion	Still above break-even, but sales softness cuts room fast.
Fixed-cost pressure	Fixed costs rise 10% to $243k a month.	$300k	$269k cushion	Higher rent, labor, or overhead lifts the floor.
Margin pressure	Variable expenses rise to 24%, cutting contribution margin to 76%.	$290k	$279k cushion	Food, staff, or event promo costs push break-even up.
Combined pressure	Revenue falls 20%, fixed costs rise 10%, and variable expenses rise to 24%.	$320k	$135k cushion	Still viable, but the margin gets thin fast.

What should you verify before signing the lease and opening an Indonesian restaurant?

Founder checklist

Before you sign, test the full cost stack against break-even, not just the rent. If the model can’t carry about $22.0K a month in fixed load and the Month 2 cash dip, wait.

1Lease Load$22.0K/mo

Sign the lease only if rent, overhead, and base payroll still fit about $22.0K a month; $4,000 rent is safe only when the full fixed stack clears break-even.

2Core Payroll$179K/yr

Hire the head chef and kitchen manager only when the Year 1 salaried payroll, about $179K, is funded through launch.

3Staffing Ramp0.5 FTE

Keep the event manager and delivery driver at 0.5 FTE in Year 1, then scale only as Friday-to-Sunday bookings grow.

4Setup Spend$144K

Stage the first build across kitchen equipment $45K, vehicles $60K, serving equipment $15K, office and IT $8K, inventory $5K, website and branding $7K, and software setup $4K before opening fully.

5Margin Guard12% inputs

Confirm suppliers can hold food and beverage ingredients at 12% of revenue, and simplify the menu if total variable costs move above 19%.

6Cash Runway$827K

Keep the Month 2 cash cushion intact at $827K, and don’t treat Month 3 breakeven as real until weekly demand is near 105 covers.
