Cost classification

Break-even in Month 17 is only useful if contractor pay, processing fees, and commissions move with revenue while rent, insurance, and compliance stay in fixed overhead. Misclassifying these costs can make the revenue target look safer than it is.

Expense	Cost	Break-Even Treatment	Common Mistake
Interpreter Contractor Fees	Variable	Model at 18.0% of first-year revenue, declining to 16.0% by the mature year.	Treating contractor pay as fixed overhead instead of tying it to billable interpretation volume.
Cloud Infrastructure and API Usage	Variable	Model at 4.0% of first-year revenue, declining to 2.0% as usage efficiency improves.	Leaving usage charges in fixed software spend and overstating contribution margin.
Sales Commission	Variable	Deduct 5.0% of first-year revenue, then apply the lower forecast rates in later years.	Counting commissions only in payroll and missing the revenue-linked payout.
Payment Processing Fees	Variable	Deduct 2.9% of first-year revenue, falling to 2.5% in the mature year.	Treating card and invoice fees as fixed bank charges.
Professional Liability Insurance	Fixed	Include $2,500 per month in fixed overhead from Month 1 through Month 60.	Spreading it as a percent of sales and understating early losses.
Office Rent and Utilities	Fixed	Include $6,500 per month in fixed overhead for the relevant planning range.	Assuming rent falls when interpretation hours drop.
Legal and Health Insurance Portability and Accountability Act Compliance Audit	Fixed	Include $1,800 per month as fixed compliance overhead.	Leaving compliance out of break-even because it is not tied to each appointment.
Sales, Customer Success, and Interpreter Network Management Headcount	Semi-fixed	Add salary capacity in hiring steps as full-time equivalents rise across the forecast.	Averaging step-up hires into a smooth percent of revenue.

How does break-even change from a lean launch mix to a full interpretation-services build?

Scenario table

Break-even improves as the mix shifts toward higher revenue and lower variable cost. Remote-heavy hours help most, while onsite work keeps pressure on the margin and makes fixed costs harder to cover.

Planning assumptions only; actual break-even will move with volume, service mix, and staffing.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch mix	$71.9k	$21.5k	$63.6k	70.1%	-$13.2k	Still below break-even; monthly loss remains.
Base operating mix	$171.9k	$49.5k	$82.7k	71.2%	$39.6k	Above break-even; this mix carries a solid monthly cushion.
Full scale mix	$309.4k	$85.0k	$95.7k	72.8%	$128.8k	Well above break-even; the cushion is strong if onsite costs stay controlled.

What breaks the break-even plan for interpretation services?

Stress test

This break-even plan is fragile until demand proves out. Year 1 revenue is still below break-even, so a small booking miss, higher interpreter pay, or a few extra fixed costs can push cash pressure past Month 16.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	Year 1 revenue is $863k, with 29.9% variable expenses and $762.8k fixed costs.	$1.09M	$226k gap	Base case is still below breakeven.
Revenue shortfall	Year 1 revenue falls 10% to $777k.	$1.09M	$312k gap	A modest booking miss widens the cash gap fast.
Fixed-cost increase	Fixed costs rise 10% to about $839k a year.	$1.20M	$334k gap	Payroll, rent, and compliance creep move breakeven out.
Margin pressure	Variable expenses rise from 29.9% to 34.9%, cutting contribution margin to 65.1%.	$1.17M	$309k gap	Higher payouts, travel, and payment fees take the cushion.
Combined pressure	Revenue falls 10%, fixed costs rise 10%, and margin drops to 65.1%.	$1.29M	$512k gap	That mix leaves a large funding hole before Month 17.

Can this interpretation business clear break-even before you lock in overhead?

Founder checklist

Do not lock in rent, hires, or platform spend until you can point to signed work that covers about $105k a month and the staffing needed to deliver it. The model breaks even in Month 17, so the real test is whether pipeline and cash can bridge that gap.

1Pipeline cover$105k/mo

Verify signed leads or near-term bookings can support this run rate, or break-even moves out fast.

2Overhead load$63.6k/mo

Verify fixed costs stay at this level before you add rent, support, sales, hardware, or platform spend.

3Margin mix~70% CM

Verify contractor fees, cloud, commission, and processing stay near 29.9% of revenue so contribution margin (what's left after variable costs) keeps Month 17 realistic.

4Coverage depth1,150 hrs

Verify contractor agreements, backup interpreters, scheduling workflow, phone quality, and onsite dispatch can cover this load without service gaps.

5Cash floor$275k

Verify you can hold this reserve through Month 16, because the cash low lands before breakeven in Month 17.

6Acquisition pace100 customers/yr

Verify $120k of Year 1 marketing at $1,200 CAC really buys about 100 customers a year, or the revenue ramp will miss.
