Which interpreter service expenses are fixed, and which move with sales?

Cost classification

Break-even is only reliable when assignment-linked labor and fees reduce contribution margin, while rent and core admin stay below the line as fixed overhead. In this model, Month 28 break-even depends on that split.

Expense	Cost	Break-Even Treatment	Common Mistake
Interpreter Compensation	Variable	Deduct from revenue before contribution margin; Year 1 rate is 22.0% of revenue.	Treating interpreter pay like overhead instead of assignment-linked labor.
Platform Hosting & Direct Tech	Variable	Deduct as delivery expense; Year 1 rate is 3.0% of revenue.	Putting all hosting below the break-even line as fixed software spend.
Sales Commissions	Variable	Deduct from each sale; Year 1 rate is 3.0% of revenue.	Ignoring commissions when estimating gross contribution per session.
Payment Processing Fees	Variable	Deduct from collected revenue; rate stays 1.5% across the model.	Using list price as cash received before card fees.
Office Rent	Fixed	Include in monthly fixed overhead at $2,500 from Month 1 through Month 60.	Spreading rent across sessions and hiding the true monthly hurdle.
Professional Services Accounting Legal	Fixed	Include in fixed overhead at $750 per month across the planning range.	Treating routine accounting and legal support as one-time startup spend.
Travel & Entertainment	Semi-variable	Model the $500 monthly baseline, then add usage-linked spend if sales activity rises.	Assuming every travel dollar scales cleanly with revenue.
Admin Payroll	Semi-fixed	Model in staffing steps because roles start in later periods and expand with capacity.	Forgetting that new hires raise the break-even point in jumps.

How does break-even move from a lean launch to full coverage for this interpreter service?

Scenario table

As the mix shifts from lean launch to full coverage, fixed staffing and admin costs rise faster than margin, so break-even revenue moves up even as the billable-hour rate improves. The real test is scheduling density and interpreter coverage.

Planning scenarios only; these are model assumptions, not guaranteed results.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch coverage	$405K	$120K	$286K	70.5%	$0	Very tight cushion; any idle time pushes break-even higher.
Base year mix	$888K	$235K	$653K	73.5%	$0	Better mix helps, but support load still keeps the model near break-even.
Full coverage scale	$1,049K	$247K	$803K	76.5%	$0	Highest cushion on paper, yet full staffing needs steady volume to hold it.

What breaks first if bookings slip or staffing costs rise?

Stress test

Break-even is thin here: Year 1 keeps 70.5% of revenue after variable costs, so every $1 of lost sales removes about $0.705 of contribution. Once staffing grows, fixed costs jump and the gap widens fast.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No stress; Year 1 costs and mix stay unchanged.	$416,000	$275,000 gap	Current revenue is still far below break-even.
Revenue shortfall	Booked revenue lands 15% below the current plan.	$416,000	$296,000 gap	A small demand miss pushes payback farther out.
Fixed-cost pressure	Year 3 staffing and overhead rise to about $663,000 a year.	$941,000	$800,000 gap	Adding support and sales staff nearly doubles the sales needed.
Margin pressure	Variable costs rise to 33.5% of revenue as pay and fees creep up.	$441,000	$300,000 gap	A 4-point margin hit lifts break-even fast.
Combined pressure	Year 5 overhead reaches about $713,000 and variable costs rise to 33.5%.	$1,072,000	$932,000 gap	Higher headcount and weaker pricing push break-even above $1.0M.

What should a founder verify before committing to the interpreter launch?

Founder checklist

Check demand, CAC, coverage, and cash before you spend. This model only works if pipeline supports the Year 1 budget, billable hours reach the lean case, and hiring waits until bookings can carry the load.

1Pipeline Proof$250 CAC

Validate enough qualified clients to support the $50,000 Year 1 marketing budget and confirm CAC can start near $250, then fall.

2Base Overhead$5.25K/mo

Cover the monthly fixed overhead before payroll, because the rent, tools, and admin spend create a hard floor.

3Margin Check70.5% CM

Keep Year 1 contribution margin near 70.5%, since interpreter pay, hosting, sales commissions, and payment fees already take 29.5% of revenue.

4Billable Load709 hrs/mo

Test scheduling for video remote and over-the-phone jobs, and lock backup interpreters, so the team can reach about 709 billable hours a month in the lean case.

5Hiring RampMonth 13

Delay the Operations Manager and Sales Manager until booking volume can absorb admin work, or payroll will outrun the model before break-even.

6Cash Cushion$364K cash

Hold the modeled minimum cash cushion through Month 28 and trim nonessential launch capex, because startup capex totals $162,000 before the business turns cash positive.
