Which software development expenses are fixed, semi-fixed, or variable for break-even?

Cost classification

Break-even is only reliable when each expense follows the right behavior. Here, payroll capacity and rent create the monthly hurdle, while cloud, project licenses, marketing, and travel move with revenue.

Expense	Cost	Break-Even Treatment	Common Mistake
CEO Lead Architect payroll	Fixed	Include the full $180,000 annual salary as a recurring monthly operating expense.	Spreading it only across billable projects and understating the monthly hurdle.
Senior Software Engineer payroll	Semi-fixed	Add salary in staffing steps as headcount rises from 1.0 FTE to 5.0 FTE.	Treating idle developer capacity as Variable when payroll keeps running.
Project Manager payroll	Semi-fixed	Increase payroll in FTE steps as delivery volume grows from 0.5 FTE to 2.5 FTE.	Modeling project management as a percentage of sales instead of staffed capacity.
Project Specific Cloud Hosting	Variable	Apply 3.0% of revenue in each forecast year before calculating contribution margin.	Putting usage hosting in fixed overhead and overstating margin at low sales.
Specialized Project Software Licenses	Variable	Apply 2.0% of revenue because the model ties these licenses to project activity.	Using the general subscription treatment for client-specific license usage.
Sales Marketing Campaigns	Variable	Use 8.0% of revenue in the first year, falling to 4.0% by the mature year.	Leaving the rate flat and missing improving sales efficiency over time.
Client Project Travel Expenses	Variable	Use 3.0% of revenue in the first year, falling to 1.0% by the mature year.	Forecasting travel as fixed even though it follows client project volume.
Office Rent	Fixed	Include $7,000 per month as fixed overhead across the relevant planning range.	Reducing rent when revenue drops, even though the lease still has to be paid.

How does break-even change from a lean software launch to a full-scale delivery model?

Scenario table

Lean plans sit closer to break-even because fixed staffing and office costs are heavy while revenue is still small. By Year 5, maintenance retainer revenue reaches $2M and the mix supports a much wider cushion.

Planning cases only; actual results will move with sales mix, delivery speed, and staffing.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch plan	$90K	$14K	$492K	84%	-$416K	Still below break-even; fixed costs outweigh coverage.
Base Year 3 scale plan	$3.88M	$504K	$976K	87%	$2.40M	Break-even is covered, with a solid buffer if mix holds.
Full Year 5 scale plan	$8.46M	$846K	$1.48M	90%	$6.14M	Strong cushion, but unbilled subcontracting would cut margin fast.

What pushes this software development plan below break-even?

Stress test

The base plan clears break-even, but the cushion depends on projects starting on time and staying close to scope. Delays, rework, or higher cloud spend can shrink that buffer fast.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$586K	$494K cushion	Base case clears break-even, so delivery needs to stay on schedule.
Revenue shortfall	Annual revenue falls 20% to $864K.	$586K	$278K cushion	Delayed client starts cut the buffer, but the plan still stays above break-even.
Fixed-cost pressure	Fixed costs rise 10% to about $541K.	$645K	$435K cushion	Overhead creep lifts the break-even line fast, so staffing and rent need control.
Margin pressure	Variable expenses rise from 16% to 21%.	$623K	$457K cushion	Underutilization, rework, or cloud spend can shave contribution margin.
Combined pressure	Revenue drops 20%, fixed costs rise 10%, and variable burden rises to 21%.	$686K	$178K cushion	One weak quarter can narrow the buffer quickly, so backlog quality matters.

What should a software development founder verify before signing a lease and hiring developers?

Founder checklist

Before you lock in developers, rent, or equipment, make sure the model can clear its $586K monthly break-even revenue target with signed work and enough cash to cover the Month 2 low point. If the current plan is only $90K a month, keep fixed commitments light.

1Signed Work$586K/mo

Do not add fixed staff until signed contracts or committed pipeline can support the $586K monthly break-even target, even if the first plan is only $90K a month.

2Base Burn$49.2K/mo

Your Year 1 salary load is about $35.8K/month and fixed overhead is $13.4K/month, so verify the pipeline covers roughly $49.2K/month before project costs.

3Cash Buffer$864K

Keep at least the $864K minimum cash cushion through Month 2, because the cash trough hits early while capex and payroll are both ramping.

4Margin Mix84% CM

The model keeps about 84% contribution margin after 5% COGS and 11% variable spend, so protect pricing and scope or break-even gets pushed out.

5Core Capacity3.0 FTE

Confirm the CEO Lead Architect, Senior Software Engineer, 0.5 Project Manager, and 0.5 Business Development Manager can cover delivery and sales before you add more senior payroll.

6Build Spend$142K

Stage the $142K equipment build and map maintenance support load before promising retainers, because furniture, workstations, infrastructure, security, and testing hardware all hit cash before revenue does.
