A $65k Bookkeeper Costs You $5,800 a Month — Here's the Arithmetic
Salary is roughly 70% of what an in-house bookkeeper actually costs. The full build-up, across the US, UK, Australia and New Zealand, plus when hiring is genuinely the right call.
Budget 1.25 to 1.4 times salary for an in-house bookkeeper once payroll taxes, benefits, software, recruitment and cover are counted — before any management time. A $65,000 US bookkeeper lands near $5,800 a month fully loaded. Comparing that salary against an outsourced monthly fee is the single most common error in this decision.
Fully loaded cost is 1.25–1.4× salary. Any comparison against a bare salary figure is understating the in-house option by 25–40%.
The build-up, line by line
Using a $65,000 US bookkeeper as the worked example. Adjust the percentages for your jurisdiction — the structure holds everywhere, only the weightings move.
- Base salary — $65,000
- Employer payroll taxes — roughly 7.65% FICA plus unemployment insurance, around $5,400
- Benefits — health, retirement match, paid leave; commonly 12–18% of salary, around $9,800
- Software seats — accounting, document capture, payroll, expense; $2,000–$4,000 a year
- Recruitment — agency fee or internal time, amortised over expected tenure; around $4,000 a year
- Equipment and workspace — $1,500–$3,000 a year
The two costs nobody puts in the spreadsheet
Management time is the first. A bookkeeper needs direction, review and escalation. If a founder or finance manager spends two hours a week on that, at any realistic hourly value, it is thousands a year that never appears in the comparison.
Key-person risk is the second, and it is larger. One bookkeeper is one point of failure. When they resign, the institutional knowledge of your ledger — why that account is coded that way, which vendor bills in advance, what the reconciliation quirk is — leaves with them. In our experience the handover gap is where most cleanup projects originate.
A single in-house bookkeeper is a single point of failure. The cost of that risk shows up later, as a cleanup project, rather than in the hiring spreadsheet.
How it looks across four markets
Fully loaded monthly cost of an in-house bookkeeper versus a comparable outsourced engagement. Local currency throughout.
- United States — in-house ≈ $5,800/mo; outsourced from $350/mo, typical engagement $1,850/mo
- United Kingdom — in-house ≈ £3,400/mo; typical engagement £1,150/mo
- Australia — in-house ≈ A$7,200/mo including superannuation; typical engagement A$2,100/mo
- New Zealand — in-house finance hire ≈ NZ$8,300/mo; bookkeeping plus virtual CFO layer ≈ NZ$3,200/mo
When hiring in-house is genuinely right
This is not a universal argument against hiring, and any comparison that concludes otherwise is selling something.
Hire in-house when transaction volume is high and heavily process-specific, when finance needs to sit in daily operational decisions, or when finance is effectively part of the product. Past roughly 50 staff, a dedicated internal finance function usually starts to justify itself on coordination alone.
Below that, most companies need senior judgement a few days a month rather than a full-time person — which happens to be the hardest shape to hire for, because nobody good wants a job that is 30% of a role.
The hybrid most people land on
An outsourced team for the transactional layer and monthly close, with an internal finance lead once headcount justifies it. The outsourced team keeps documented process and cover; the internal hire owns relationships, planning and the parts that need to be in the room.
That path is also why the file-ownership question matters. If your books are in your own accounting subscription with documented process, bringing finance in-house later is a handover, not a migration.
