Which ramen restaurant expenses are fixed, and which move with sales?

Cost classification

Break-even is only reliable if each expense behaves the right way in the model. Here, fixed monthly overhead and semi-fixed payroll set the floor, while ingredients, fees, and supplies move with sales volume.

Expense	Cost	Break-Even Treatment	Common Mistake
Rent	Fixed	Use $10,000 per month from Month 1 through Month 60.	Lowering rent when traffic is slow.
Insurance	Fixed	Use $750 per month regardless of cover count.	Tying insurance to sales volume.
POS and reservation software	Fixed	Use $400 per month as committed operating overhead.	Modeling it as a per-order fee.
Food ingredients	Variable	Apply the modeled percentage of sales, starting at 10.0% in the first year.	Using one flat dollar amount per month.
Beverage ingredients	Variable	Apply the modeled percentage of sales, starting at 4.0% in the first year.	Ignoring the beverage mix shift over time.
Credit card fees	Variable	Apply the modeled fee rate, starting at 2.0% of sales in the first year.	Treating payment fees as fixed overhead.
Utilities	Semi-variable	Model $2,000 monthly, but watch usage if prep volume rises.	Assuming utilities never move with kitchen volume.
Salaried labor	Semi-fixed	Use $36,500 monthly in the first year, then step up with staffing levels.	Treating all payroll as variable before traffic is proven.

How does break-even change as the ramen shop moves from a lean opening case to a full Year 3 build?

Scenario table

Lean Year 1 is close to break-even. By Year 2 and Year 3, higher covers and ticket size widen the cushion faster than fixed payroll rises.

Planning assumptions only; actual results will vary with traffic, labor use, and menu mix.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean Year 1 opening case	$85,042	$14,883	$51,950	82.5%	$18,209	Near break-even, so small traffic dips can cut the cushion fast.
Base Year 2 operating case	$123,738	$20,515	$58,742	83.4%	$44,481	Clearer cushion, but wage hours still need to track cover growth.
Full Year 3 ramp case	$166,725	$25,996	$65,533	84.4%	$75,196	Strong cushion, but added cooks and front-of-house labor must be filled by sales.

What breaks the ramen restaurant’s break-even plan?

Stress test

Year 1 starts about $22,072 above break-even, so it has room. But sales below $63,000 a month, higher labor, or a 1-point margin hit can wipe out that cushion fast.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$62,970	$22,072 cushion	Year 1 stays above water if traffic holds.
Revenue shortfall	Monthly sales fall to $63,000.	$62,970	$30 cushion	Any further drop flips the month into loss.
Fixed-cost pressure	Monthly labor runs $5,000 over plan.	$69,030	$16,012 cushion	Overtime and staffing gaps eat most of the buffer.
Margin pressure	Variable costs rise by 1 point of sales.	$63,742	$21,300 cushion	Broth waste, toppings waste, or card fees push break-even up.
Combined pressure	Monthly labor runs $5,000 over plan and variable costs rise 1 point.	$69,877	$15,165 cushion	Two small misses together cut the buffer hard.

What should you verify before signing the lease and buildout for this ramen restaurant?

Founder checklist

Before you sign the lease, prove the opening can hold these numbers. The ramen shop needs 385 weekly covers in Year 1, $15,450 of fixed overhead before payroll, and $565,000 of cash at the Month 6 low point.

1Launch Demand385/wk

Verify $45 midweek and $55 weekend tickets still produce 385 weekly covers in Year 1, because that is the demand base behind Month 4 break-even.

2Fixed Load$15.45K/mo

Confirm rent stays at or below $10,000 and all non-payroll fixed costs stay at $15,450 a month, or break-even moves out fast.

3Menu Margin82.5% CM

Hold food ingredients at 10.0%, beverage ingredients at 4.0%, and card fees plus supplies at 3.5%, which leaves an 82.5% contribution margin for payroll and rent.

4Staffing Ramp$36.5K/mo

Lock the Year 1 payroll plan at $36,500 a month unless traffic clearly supports more, because labor is the fastest way to erase break-even.

5Cash Cushion$565K min

Hold at least $565,000 of cash through Month 6, since buildout, equipment, and inventory hit before sales catch up.

6Capacity Fit525-665/wk

Verify seating, prep, and service can handle 525 to 665 weekly covers in Year 2 and Year 3, so volume growth does not strain the kitchen.
