Want to see the six biggest income drivers?
1
Study Volume
18 cust
More completed studies lift revenue fastest, and the model starts with 18 Year 1 customers at a $2,500 CAC.
2
Study Fee
$195/hr
A higher fault current study rate raises revenue on every hour sold, so price discipline feeds straight into owner take-home.
3
Billable Hours
185 hrs/mo
More billable hours spread payroll and other fixed costs across more work, which is what moves EBITDA first.
4
Labor Mix
28%
Travel, commissions, software, and drafting costs pull down margin, so lean delivery keeps more revenue in the business.
5
Specialized Overhead
$129.6K
This annual base cost has to be covered before profit starts, so every extra study helps absorb it.
6
Reserve Policy
$544K
The model bottoms near $544K cash in Month 20, so the reserve and the $175K owner salary need tight control while growth ramps.
Can a solo engineer make money with short circuit analysis?
Yes, a solo engineer can make money with a Short Circuit Analysis Service, but the current model is not a pure solo shop; it assumes a Principal Professional Engineer at $175,000 plus engineering support. For setup details, see How To Write A Business Plan For Short Circuit Analysis Service?, because Year 1 shows 280% variable delivery costs and $129,600 fixed overhead, so owner income depends on billable capacity, turnaround, software cost, sales time, and review load.

Launch model
This is a Year 1 ramp with about $663,000 revenue and negative EBITDA, so the owner salary is modeled but draws are thin.
This is a Year 3 scale case with about $1.938 million revenue and about $316,000 EBITDA, so salary and some distributions can start to fit.
This is a Year 5 scale case with about $3.691 million revenue and about $1.289 million EBITDA, so the owner can take salary plus meaningful distributions.
Typical setup
The model carries a full technical bench, half-time business development, $45,000 marketing, and $129,600 fixed overhead, but project volume still leaves EBITDA negative.
The firm runs with a larger engineering team, a full-time sales lead and coordinator, $75,000 marketing, and stronger billable hours across the main study mix.

Short Circuit Analysis Service Core Six Income Drivers
Completed Study Volume
Completed Study Volume
Completed study volume is the number of short circuit analysis projects that make it from lead to signed scope to delivered report. It only lifts owner income when qualified leads convert and reports ship on time; otherwise, marketing spend turns into idle engineering time and slow cash.
Here’s the quick math: $45,000 ÷ $2,500 CAC ≈ 18 customers in Year 1, and $110,000 ÷ $2,100 CAC ≈ 52 customers in Year 5. More completed studies should raise revenue and spread the $10,800/month fixed overhead, but weak lead quality, delayed site data, and review bottlenecks can cut profit fast.
Track lead-to-report throughput
Measure qualified lead rate, win rate, and on-time delivery together. A full pipeline does not help if site data comes in late or licensed review becomes the bottleneck.
Before adding more marketing, test whether the team can handle about 52 customers a year without slipping on quality. If turnaround slips, cash arrives later, rework rises, and owner pay gets squeezed even when bookings look strong.
Track leads, wins, and shipped reports.
Reject bad site data early.
Match sales to review capacity.
Delivery Labor Mix
Delivery Labor Mix
This driver is the split between subcontracted drafting, staff payroll, and the licensed engineer time needed to review and sign off on each study. In Year 1, subcontracted drafting is 60% of revenue; by Year 5 it falls to 40%. That shift can lift gross margin, but only if staff leverage rises faster than review time and coordination overhead.
Here’s the quick math: less outsourced work usually means more value stays in-house, yet the firm still needs licensed engineering leadership for quality control. If support labor adds capacity but review hours stay high, project profit can look fine on paper and still leave less cash for owner pay.
Measure Labor by Job, Not by Payroll Total
Track direct delivery labor separately from fixed overhead so you can see true project margin. For each job, compare subcontractor cost, staff engineer hours, and licensed review hours against fee. A job is stronger when drafting and coordination hours fall faster than revenue, not just when the team gets bigger.
Watch three ratios: subcontractor cost as % of revenue, licensed review hours per study, and staff hours per completed report. If subcontracting drops from 60% to 40% but review time creeps up, the margin gain shrinks. One clean rule: pay for capacity, but keep the signer’s time scarce and priced into the fee.
Track labor by project.
Price review time into scope.
Separate overhead from delivery.
Cut rework before hiring more.
Average Study Fee
Average Study Fee
Average study fee is the main pricing lever here because each job is expert-heavy and rework is expensive. In this model, fault current study rates rise from $195/hour in Year 1 to $230/hour in Year 5, while protective coordination moves from $210/hour to $245/hour. If pricing misses complexity, number of buses, site data gaps, or turnaround pressure, revenue can look fine while margin and owner pay slip.
Here’s the quick math: a higher fee raises cash per study, but under-scoping cuts profit fast because engineering time, review time, and correction time all sit inside the job. What this estimate hides: projects with poor document quality or missing site data usually take longer than planned, so the owner needs a pricing floor that protects gross margin, not just booked revenue.
Price by complexity, not just hours
Track study type, number of buses, missing one-line data, and requested turnaround before quoting. Use those inputs to separate simple jobs from high-risk jobs, then price review-heavy work higher. A strong fee structure supports owner take-home because it keeps expert labor from getting buried inside fixed-price work that should have been billed at a higher hourly rate.
Charge more for data gaps.
Charge more for rush deadlines.
Charge more for complex systems.
Review estimate hours against actuals.
Raise rates when rework repeats.
Protective coordination should usually price above basic fault current work, since it adds analysis depth and more client revisions. If a study is likely to need extra modeling or multiple sign-off rounds, build that into the fee up front so revenue turns into real profit instead of unpaid engineering time.
Billable Utilization
Billable Utilization
Billable utilization is the share of paid time spent on analysis, modeling, review, and client delivery. In this service, average billable hours per active customer rise from 185 per month in Year 1 to 225 per month in Year 5. That helps owner income because more paid work spreads the same fixed overhead across more revenue and lifts profit available for draw.
The drain is time spent on admin, quoting, rework, and collections. If those tasks crowd out billable work, take-home pay falls even when demand is solid. But if utilization gets pushed too hard, report quality or turnaround can slip, and that can trigger rework, delays, and slower cash collection.
Raise Paid Time Share
Track billable hours by engineer, by client, and by project stage. The key inputs are hours sold, hours delivered, and hours lost to cleanup. When billable hours per active customer move from 185 to 225, the same team can support more owner pay without adding as much overhead.
Protect utilization with tighter scope notes, faster site-data requests, and a required final review before issue. If turnaround slips or report quality drops, collections risk rises and the utilization gain can vanish. One clean report beats two rushed revisions.
Reserves And Reinvestment
Keep a cash reserve before owner draws
Reserves are the cash buffer that pays for slow months, software renewals, insurance renewals, hiring, equipment, and taxes. In this business, fixed overhead is $10,800 per month, so a 3-month reserve starts at $32,400 before any renewal spikes. Owner draw is not the same as profit, so a profitable month can still be a bad month for cash.
That matters more when setup cash was heavy: $123,500 in initial capital expenses, including $25,000 workstations, $45,000 software licenses, and $18,000 measurement equipment. If those costs were funded from operating cash, distributions should stay conservative until reserves are rebuilt. This is planning logic, not tax advice.
Build a reserve rule tied to overhead
Track months of fixed overhead covered, renewal dates, and expected collections. If software subscriptions run at 120% of revenue in Year 1 and insurance is $2,500 per month, the reserve has to cover more than just rent and payroll. The goal is simple: protect pay from cash dips, not just from losses.
Use a clear floor for distributions. For example, if reserve cash falls below 3 months of overhead, pause owner draws and rebuild cash first. Watch the gap between profit and cash each month, because a short-circuit analysis firm can show paper profit while still needing money for renewals, hiring, or a new instrument replacement.

Collections lag in days
Owner draw versus profit
Specialized Overhead
Specialized Overhead
Specialized overhead is the fixed cost of running this analysis practice: software subscriptions, professional liability insurance, IT security, dues, admin, and office costs. Here’s the quick math: fixed overhead is $10,800 per month, or $129,600 per year, and insurance alone is $2,500 monthly. That load cuts distributable cash before the owner sees pay, so early revenue growth matters more than in a low-overhead service.
The pressure is worst in ramp-up, when software subscriptions run at 120% of revenue in Year 1 and still 80% in Year 5. If revenue lags payroll and sales costs, owner draw gets squeezed fast. The key inputs are monthly revenue, subscription cost, insurance, and office/admin spend; this driver tells you how much of each project fee is left for profit.
Cut the Fixed Load
Track overhead as a % of revenue and as cash per month. If software, insurance, and admin are rising faster than billings, delay nonessential spend and recheck pricing before adding staff. Watch the gap between revenue and $10,800 monthly fixed overhead; that gap is the cash available for owner pay, taxes, and reinvestment.
