Labor Productivity Calculator

Calculate labor productivity (output per labor hour), productivity index, and unit labor cost to measure workforce efficiency.

Total Output (units, $, or items produced)

Number of Workers

Hours Worked per Worker

Hourly Wage Rate ($) (optional — for unit labor cost)

Baseline / Standard Productivity (units per hour) (optional — for productivity index)

Calculate

function labCalc() { const resultDiv = document.getElementById('lab-result');

const totalOutput = parseFloat(document.getElementById('lab-total-output').value); const numWorkers = parseFloat(document.getElementById('lab-num-workers').value); const hoursPerWorker = parseFloat(document.getElementById('lab-hours-per-worker').value); const wageRate = parseFloat(document.getElementById('lab-wage-rate').value); const baselineProductivity = parseFloat(document.getElementById('lab-baseline-productivity').value);

// --- Validation --- const errors = []; if (isNaN(totalOutput) || totalOutput 0) { resultDiv.style.display = 'block'; resultDiv.innerHTML = 'Please fix the following:' + errors.map(e => '').join('') + ''; return; }

// --- Core Calculations --- const totalLaborHours = numWorkers * hoursPerWorker; const laborProductivity = totalOutput / totalLaborHours; // units per labor-hour const outputPerWorker = totalOutput / numWorkers; // units per worker

// Optional: Unit Labor Cost let ulcHTML = ''; if (!isNaN(wageRate) && wageRate >= 0) { const totalLaborCost = wageRate * totalLaborHours; const unitLaborCost = totalLaborCost / totalOutput; // $ per unit of output ulcHTML = Total Labor Cost$${totalLaborCost.toLocaleString('en-US', {minimumFractionDigits:2, maximumFractionDigits:2})} Unit Labor Cost$${unitLaborCost.toFixed(4)} per unit; }

// Optional: Productivity Index
let piHTML = '';
if (!isNaN(baselineProductivity) && baselineProductivity > 0) {
const productivityIndex = (laborProductivity / baselineProductivity) * 100;
const piLabel = productivityIndex >= 100
? '▲ Above baseline': '▼ Below baseline'; piHTML = Productivity Index${productivityIndex.toFixed(2)}% ${piLabel}; }

// --- Efficiency Rating --- let efficiencyLabel = ''; if (laborProductivity === 0) efficiencyLabel = 'No Output'; else if (laborProductivity MetricValue Total Labor Hours${totalLaborHours.toLocaleString('en-US', {minimumFractionDigits:2, maximumFractionDigits:2})} hrs Labor Productivity${laborProductivity.toFixed(4)} units / labor-hour Output per Worker${outputPerWorker.toFixed(4)} units / worker ${ulcHTML} ${piHTML} Efficiency Rating${efficiencyLabel} `; }

#### Formulas Used

Labor Productivity

Labor Productivity = Total Output ÷ Total Labor Hours

Total Labor Hours = Number of Workers × Hours Worked per Worker

Output per Worker

Output per Worker = Total Output ÷ Number of Workers

Unit Labor Cost (ULC) — requires wage rate:

Total Labor Cost = Hourly Wage Rate × Total Labor Hours

Unit Labor Cost = Total Labor Cost ÷ Total Output

Productivity Index — requires baseline productivity:

Productivity Index (%) = (Labor Productivity ÷ Baseline Productivity) × 100

A value above 100% means the workforce is outperforming the baseline standard.

#### Assumptions & References

Labor productivity is measured as partial factor productivity — output relative to labor input only; it does not account for capital, materials, or technology inputs.
