Calculation

First-Year Resignation Rate formula

(First-Year Resignations ÷ Total New Hires) × 100

Formula components

First: The consistently counted first included in the metric’s documented population and period.
Year Resignations: The consistently counted year resignations included in the metric’s documented population and period.
New Hires: The consistently counted new hires included in the metric’s documented population and period.

How to calculate First-Year Resignation Rate

Define the business scope, reporting period, and the event or status that qualifies for First-Year Resignation Rate.
Remove duplicates and exclusions according to the documented rule, while retaining a reconciliation count.
Collect each input in the workbook formula from systems that use the same cut-off and unit.
Apply (First-Year Resignations ÷ Total New Hires) × 100 and label the result with its period, unit, and relevant segment.

Worked example

First-Year Resignation Rate example

A fictional hr analytics team calculates First-Year Resignation Rate for one agreed reporting period.

First = 78.
Year Resignations = 800.
First-Year Resignation Rate = 78 ÷ 800 × 100 = 9.8%.

First-Year Resignation Rate is 9.8%.

About 9.8 in every 100 eligible units meet the metric’s stated condition.

How to interpret the result

Compare First-Year Resignation Rate over a consistent cadence and break it down only by segments large enough to support a decision. Review the formula inputs beside the result so teams can distinguish a real operating shift from a denominator or mix effect.

There is no single target that fits every organisation. Interpretation depends on role family, location, tenure, workforce mix, company size, policy, and measurement period. Document the comparison group before labelling a result strong or weak.

Common mistakes and limitations

Inconsistent scope: Changing the included business units, products, channels, or populations makes the trend look different even when underlying performance is unchanged.
Mismatched periods: Formula inputs from different cut-off dates or time windows do not describe one coherent result.
Reading the headline alone: A single value can hide offsetting movement across segments, volumes, or contributing formula components.
Assuming one universal target: A useful comparison depends on role family, location, tenure, workforce mix, company size, policy, and measurement period; use like-for-like internal trends and clearly documented peer groups.
