HR Metrics Calculators

Fifteen of the numbers people leaders report on most — worked out for you as you type.

How to use these calculators

  1. Pick your metric

    Every card shows the formula it uses, so you can see exactly how the number is worked out — and check it against your own reporting.

  2. Type your figures in

    Results appear as you type — there is no submit button. Paste straight from a spreadsheet if you like; dollar signs and commas are handled.

  3. Not sure? Try an example

    Each card has a Try an example button that fills in realistic numbers so you can see it work, and a Clear button to start again.

Turnover & Retention

3 calculators

How many people are leaving, how many are staying, and how much time is lost to unplanned absence.

Employee Turnover Rate

Employees who left ÷ Average headcount × 100

Turnover rate

The share of your workforce that left during the period.

Retention Rate

Employees who stayed ÷ Headcount at start × 100

Retention rate

The share of your starting workforce still with you at the end.

Absenteeism Rate

Unplanned absence days ÷ Scheduled workdays × 100

Absenteeism rate

Unplanned absence days divided by scheduled workdays across all employees. Excludes approved annual leave, public holidays and workers compensation.

Recruitment

5 calculators

What hiring costs you, how long it takes, and how well your offers land.

Cost per Hire

Total recruitment costs ÷ Number of hires

Cost per hire

Average spend to fill one role, including advertising, agency fees and referral bonuses.

Time to Fill

Date offer accepted − Date vacancy opened

Time to fill

Days from requisition approval to offer acceptance. Business days exclude weekends only — public holidays vary by state and are not deducted. Measuring to the start date instead gives a different metric, time to start.

Time to Hire

Date offer accepted − Date candidate applied

Time to hire

Measured from the candidate’s side: how long they waited from applying to accepting. Business days exclude weekends only — public holidays vary by state and are not deducted. Distinct from Time to Fill, which starts when the vacancy opened.

Offer Acceptance Rate

Offers accepted ÷ Offers extended × 100

Acceptance rate

The share of your offers that candidates accept.

Selection Ratio

Candidates hired ÷ Total applicants × 100

Selection ratio

How selective the process is. Shown as a percentage and as a one-in-N ratio.

Productivity, Cost & Investment

7 calculators

What your people cost, what they generate, and what your investment in them returns.

Revenue per Employee

Total revenue ÷ Average headcount

Revenue per employee

Revenue generated per head. Useful for tracking productivity as you grow.

Overtime as % of Regular Hours

Overtime hours ÷ Regular hours × 100

Overtime

Overtime measured against regular hours. Some dashboards divide by total hours instead, which gives a different figure from the same data.

Benefit Cost per Employee

Total benefits expense ÷ Number of employees

Benefit cost per employee

Average annual benefits spend per employee.

Labour Cost as % of Revenue

Total labour cost ÷ Total revenue × 100

Labour cost

The share of revenue going to wages, on-costs and benefits.

Salary Increase Rate

Total salary increase ÷ Total payroll before increase × 100

Salary increase rate

The aggregate cost of a pay review as a share of the payroll it applied to.

Training Cost per Employee

Total training cost ÷ Number of employees trained

Cost per trained employee

Spend per person trained, not per head of workforce — divide by everyone and you understate what the training actually cost to deliver.

Training ROI

(Financial benefit − Training cost) ÷ Training cost × 100

Training ROI

Return on a training investment. A negative result means the programme cost more than it returned.
