What Is 90-Day Retention?

90-day retention is the percentage of new hires still employed 90 days after their start date. It's a standard benchmark for hourly and shift-based roles because most turnover in these roles happens early — often in the first few weeks, before a worker has fully settled into the job.

Tracking retention at the 90-day mark gives operations leaders an early read on whether new hires are sticking, without waiting a full year to find out.

Why the First 90 Days Matter

The early weeks of a new hourly role are when a worker forms their opinion of the job — whether the schedule works for their life, whether the work matches what they expected, and whether the workplace feels worth staying for. If those first impressions are negative, workers tend to leave quickly, often before an employer has recouped the cost of hiring and training them.

That makes 90-day retention a more useful signal than overall annual turnover for hourly workforces — it isolates the window where the most preventable losses happen.

What Affects 90-Day Retention

• Onboarding quality — How clearly a new hire understands expectations, schedule, and pay in their first days on the job.
• Schedule fit — Whether the shifts they're assigned match the availability they were hired for.
• Workload consistency — Predictable, manageable workloads versus chaotic first weeks.
• Communication — Whether a new hire has a clear point of contact for questions or issues.
• Pay and shift reliability — Whether the hours and pay match what was promised at hire.

How to Calculate It

90-day retention rate is calculated by dividing the number of hires from a given period still working at the 90-day mark by the total number of hires from that period, then multiplying by 100. Tracking this consistently, cohort by cohort, makes it possible to spot whether a change in onboarding, scheduling, or pay is helping or hurting.

How GigSmart Helps

A big driver of early turnover in hourly roles is a mismatched schedule — new hires taking shifts that don't actually fit their availability. G-Force gives operations leaders the scheduling and time tracking tools to build schedules the core team can actually work, reducing the early friction that drives early exits.

When the core team is stretched thin covering gaps left by recent turnover, G-Flex lets you bring in flex workers to cover shifts without pressuring new hires into unsustainable schedules while they're still ramping up. And for operations building out permanent roles, G-Board supports hiring for those positions from the start.
