Find out how many of your people are leaving and what it’s costing you. This free calculator works out your employee turnover rate from a few simple inputs: the number of employees who left over a period and your average headcount for that same period. The result is a clear percentage you can track over time, compare between teams or departments, and benchmark against your industry. Turnover is one of the most telling signals of organisational health: a rising rate often points to issues with pay, management, workload or engagement, while a stable, healthy rate reflects a workplace people want to stay in. Built for HR teams, people managers and business owners, this tool turns raw leaver numbers into a metric you can actually act on, it’s the first step toward understanding your retention, estimating the cost of churn, and building a compensation and retention strategy that keeps your best people.
