Attrition is one of those costs that never gets a single invoice, so it is easy to underestimate. But every departure sets off the same expensive chain: recruit, hire, onboard, and wait for the new person to get up to speed. Multiply that across a year and the number gets your attention.
Estimates from HR research, including figures often cited by SHRM, commonly put the cost of replacing an employee at roughly half to two times their annual salary, depending on the role's seniority and specialization. Senior and hard-to-fill roles sit at the high end. Even at the low end, replacing a $50,000 employee can cost $25,000 or more. Size it for your team in the employee turnover cost calculator.
The two overlap but are not the same. A bad hire is a single mismatch that ends quickly. Attrition is the ongoing rate at which people leave, including good employees you wanted to keep. High attrition is the more strategic problem, because it points at something about pay, management, or culture rather than one hiring miss. We cover the one-off case in the cost of a bad hire.
Turnover responds to the obvious levers: competitive pay, decent management, a clear path to grow, and reasonable workload. Exit interviews tell you why people actually leave, which is often different from what you assume. Because replacement is so expensive, even modest improvements in retention usually pay for themselves quickly.
You cannot manage what you do not measure. Calculating your turnover rate, the number of departures over a period divided by your average headcount, gives you a baseline to watch and to compare against your industry. Not all turnover is bad; some is healthy renewal. But a rate that is climbing, or far above your peers, is a signal worth chasing down before the replacement costs pile up.
Replacing an employee commonly costs about half to two times their annual salary, per HR research often cited by SHRM, with senior and specialized roles at the high end. Even replacing a $50,000 employee can cost $25,000 or more once everything is counted.
Recruiting and hiring, onboarding and training, lost productivity while the role is empty and the replacement ramps up, and the knowledge and relationships that leave with the departing employee. Most of it is indirect and easy to overlook.
A bad hire is a single mismatch that ends quickly. Attrition is the ongoing rate at which employees leave, including ones you wanted to keep. High attrition usually points to pay, management, or culture, not a one-time hiring mistake.
Competitive pay, good management, clear growth paths, and reasonable workloads are the main levers. Exit interviews reveal why people actually leave. Because replacing people is so costly, even small gains in retention tend to pay for themselves.
