New Hire Retention Rate: Formula and Example

New hire retention rate is the percentage of employees who joined in a given period and are still employed after a set time, usually 6 or 12 months from joining. It mirrors early attrition over a longer window and shows whether hiring and the whole first year of employment are working.

Formula

New hire retention rate (%) = Joiners in the cohort still employed at the checkpoint / Total joiners in the cohort x 100

Term	Meaning
Cohort	All employees who joined in a defined period, such as calendar year 2025.
Checkpoint	A fixed length of service, such as 12 months, measured from each person's own joining date.
Still employed	Cohort members on the rolls on the day they complete the checkpoint.

Worked example

A logistics company in Nagpur hired 80 people in calendar year 2025: 30 drivers, 40 warehouse associates and 10 supervisors. HR checks each person on the first anniversary of their own joining date. By 31 December 2026 all had passed it, and 62 were still employed: 20 drivers, 34 warehouse associates and 8 supervisors.

Cohort = 30 + 40 + 10 = 80 joiners
Still employed at 12 months = 20 + 34 + 8 = 62
New hire retention = 62 / 80 x 100 = 77.5%
Lost within 12 months = 80 minus 62 = 18, which is 18 / 80 x 100 = 22.5%
By role: drivers 20 / 30 x 100 = 66.67% (rounded to 2 decimals), warehouse 34 / 40 x 100 = 85%, supervisors 8 / 10 x 100 = 80%

Result: 77.5 percent of 2025 joiners stayed a full year. Drivers are the weak spot at 66.67 percent, so the company should look first at driver onboarding, routes and pay.

Measuring from each person's joining date

A common shortcut is to take everyone who joined in 2025 and check who is still employed on 31 December 2025. That gives a December joiner one month and a January joiner eleven, so the result means little. Measure each person at their own 12-month anniversary, and publish the cohort figure only after the last joiner has reached it. The same logic applies to a 6-month checkpoint.

Reading the result by role and source

Compare each cohort with the previous year's cohort, and split it by role, location, source of hire and hiring manager. The overall figure moves slowly; the splits show where to act. Pair it with the probation confirmation rate. Joiners who were confirmed but still left before 12 months point to problems after onboarding, such as the manager, the roster or pay progression, rather than to hiring mistakes.

6-month retention: early fit and onboarding.
12-month retention: the full first-year experience.
Retention by source: whether referrals, job portals or consultants bring people who stay.

Pitfalls when building cohorts

Leaving out joiners who quit in the first week, on the grounds that they never really started, hides the weakest part of your hiring. Counting internal transfers as new hires is the opposite error and inflates the cohort. Rehires need a rule too: decide whether a returning employee enters a new cohort, and apply the same rule every year.

How to improve it

Make job advertisements match the real job: shift pattern, travel, targets and pay dates.
Run a structured induction in the first week, including who to ask for help with what.
Check in at 30, 90 and 180 days through a short conversation, not a form.
Explain the first payslip line by line, including PF, ESI and professional tax.
Mark the first work anniversary personally and share a plan for the second year.

Tracking it in ZeniaHR

Joining dates, last working days and exit reasons come from ZeniaHR employee records, so each joiner's status at the 12-month checkpoint can be checked. The Dashboard shows joiners and onboarding status, and Celebrations and Praise marks each work anniversary on the Company Wall. Without a cohort report, match each joiner's first anniversary against the previous employee list in a spreadsheet to get the rate.

Frequently asked questions

How do you calculate new hire retention rate?

Take all employees who joined in a period, check which of them are still employed on their own 6-month or 12-month anniversary, and divide that number by the total joiners. Multiply by 100. For example, 62 of 80 joiners still employed after 12 months gives a new hire retention rate of 77.5 percent.

What is the difference between new hire retention and early attrition?

They look at the same group from opposite sides, usually over different windows. Early attrition counts joiners who left within a short window, such as 90 days. New hire retention counts joiners still employed at a later checkpoint, such as 12 months. Tracking both shows whether exits happen in the first weeks or later in the year.

Should rehired employees be counted as new hires?

Decide once and apply the rule every year. Many companies count a rehire as a new hire when there was a break in service, because the person goes through hiring and onboarding again. Mark rehires in your data so you can also report each cohort without them.
