Comparing a salary to a monthly fee is a lot like comparing the sticker price of a car to a rideshare budget. The sticker is only the beginning. There's insurance, gas, parking, that one weird noise, and the fact that the car sits in the driveway most of the day.
The cost of hiring a full-time controller works the same way. The salary is the number everyone looks at, and it's the smallest part of the surprise.
This article gives you a worksheet to calculate the full cost of an in-house controller, explains what drives fractional controller cost, and covers the non-money differences that often decide it.
What goes into the cost of hiring a full-time controller?
Salary first. Controller salaries vary a lot by region, industry and experience, so pull current data for your market (job boards and recruiter salary guides are a reasonable start) instead of trusting a national figure.
Then add the parts that don't appear in the job posting:
- Employer payroll taxes: Social Security at 6.2% (up to the annual wage base) and Medicare at 1.45%, plus federal and state unemployment taxes
- Benefits: health insurance, retirement contributions, paid time off
- Recruiting: agency fees for senior finance roles can be significant, or your own time if you hire directly
- Software, hardware and training
- Bonus or profit-sharing, if offered
- Your time managing and reviewing the role
The same list applies to in house accountant cost at any level, just with a smaller salary line.
A worked example: the full-cost worksheet
To keep the math readable, say the base salary is a round $100,000. That's a placeholder for the arithmetic, not a market rate. Swap in the number from your own research.
- Base salary: $100,000
- Employer Social Security and Medicare (7.65%): $7,650
- Unemployment taxes (varies by state): say $500
- Health insurance and other benefits (hypothetical): $14,000
- Retirement match at 3%: $3,000
- Software licenses, laptop and training: $3,000
- Recruiting cost, spread over an expected three-year tenure: say $8,000 a year
Annual total: $136,150, or about $11,350 a month. That's roughly 36% above the salary alone, and it still doesn't include your management time or a bonus.
It also doesn't include a bookkeeper. A full-time controller in a small business either does the bookkeeping too (an expensive way to categorize credit card charges) or needs someone doing it underneath them. Add that person's full cost if so.
What drives fractional controller cost?
An outsourced controller is usually priced as a monthly fee for a defined scope. The main drivers:
- Transaction volume and the number of bank, card and loan accounts
- Number of entities and locations
- Complexity: inventory, job costing, deferred revenue, multiple revenue streams
- Close deadline and reporting requirements (lenders and investors often want more)
- The current state of the books, since cleanup and catch-up are separate work
Our article on outsourced accounting cost goes line by line through what each part of an outside accounting team costs and why.
At ABFI, controller oversight is part of a fractional accounting department, so the fee covers a team. Monthly starting points on our pricing page run from $850/month for Core Accounting to $2,750/month for the Fractional Department tier, with cleanup and catch-up scoped separately. The Scope & Investment Estimator there gives a planning range for your situation.
The differences that don't show up in the math
Cost is one column. These are the others:
Coverage. A single in-house controller takes vacations, gets sick and sometimes leaves. When they do, the close stops. An outsourced team has backup built in.
Review. A solo controller has nobody reviewing their work unless you do. An outsourced department usually builds review into the process.
Daily presence. A full-time controller is in the building, knows the operations staff, and can answer questions in minutes. For businesses with heavy daily accounting activity, that matters.
Fit for stage. Before the workload fills a full week, a full-time hire tends to drift into bookkeeping or sit underused. After it fills the week, outsourcing can start to feel stretched.
If you're still weighing whether you need the role at all, our list of signs for when to hire a controller is the place to start.
When does full-time win?
Full-time usually makes sense when the controller workload fills the week on its own, you have an accounting team that needs daily supervision, or you need someone on site for operations like inventory counts. The same stage logic applies one level up, which our guide on fractional CFO vs full-time CFO walks through.
Until then, ABFI's controller services give you controller oversight, a monthly close and a Client Accounting Manager coordinating the handoffs, without the full-time cost structure.
Questions owners ask
How much more than salary does an employee really cost?
It depends on benefits, location and recruiting, but payroll taxes, benefits and overhead commonly add a meaningful percentage on top of base pay. Build your own estimate with a worksheet like the one above.
Is an outsourced controller cheaper than an in-house accountant?
It can be, depending on scope. Compare the full annual cost of the in-house role, including benefits and the bookkeeping beneath it, with the outsourced fee for the same work.
Can I start outsourced and hire full-time later?
Yes, and it's a common path. An outsourced controller can build the close process and controls, then help you define and hand off to an in-house hire when the workload justifies it.
