Recruitment Agency Fee vs In House Calculator NZ 2026
This calculator compares what a recruitment agency would charge against what it costs to run the hire yourself, and gives you the break-even percentage where the two meet. You enter the salary of the role, the agency percentage you have been quoted, and then the pieces of doing it in house: advertising, any assessment or checking costs, and the hours your HR people and the hiring manager will actually spend, at their own hourly cost. The hours are the part that decides the answer and the part almost every comparison leaves out. Writing the ad, shortlisting, running interviews, checking references and holding internal debriefs adds up fast, and manager time is expensive, so a process that feels free because nobody invoices for it can quietly cost several thousand dollars. Cost those hours at the loaded rate of the people spending them rather than their base salary, because employer KiwiSaver and the ACC levy ride on their time too. On pure money an agency is rarely cheaper for a straightforward role that attracts good applicants, and the break-even figure here usually lands in the low single digits as a percentage of salary, well below what any agency charges. Where an agency earns its fee is a thin market, a confidential search, a team with no hours to spare, or a role where a bad hire would be very expensive and proper screening genuinely reduces that risk. Treat this as the money side of the decision rather than the whole of it.
An agency would have to charge under 4.1% of salary to match doing this in house. Money is one input: a thin market, a confidential search or no hours to spare can all justify a fee well above the break-even.
How it works
The agency cost is the salary multiplied by the fee percentage. The in house cost adds advertising, assessment and checking costs, and the hours your own people spend valued at their loaded hourly cost. The difference between the two is the saving, reported in whichever direction it falls. The break-even agency fee divides the in house cost by the salary and expresses it as a percentage: that is the fee at which an agency would cost exactly what doing it yourself costs, and anything above it means the agency is more expensive on pure money. Your own hours are totalled separately, because a comparison that looks good on cost can still be the wrong call when the hours do not exist.
Worked example
A role paying $75,000 has been quoted at an 18 percent agency fee, which is $13,500. Doing it in house means $800 of advertising, $500 of assessment and checks, 20 hours of HR time at a loaded $45 an hour, which is $900, and 12 hours of the hiring manager's time at a loaded $70 an hour, which is $840. That comes to $3,040 and 32 hours of internal time. Running the hire yourself is therefore about $10,460 cheaper, and an agency would need to charge under 4.1 percent of salary to match it. Very few do, which is why the money almost always favours in house and why the decision usually turns on capacity and market rather than cost.
