Contractor Contract Value Calculator
Estimate the total contract value for a contractor engagement by factoring in hourly rate, hours worked, overhead, profit margin, and reimbursable expenses.
Hourly Rate ($/hr)
Hours per Week
Contract Duration (weeks)
Overhead Rate (%)
Profit Margin (%)
Reimbursable Expenses ($)

function conCalc() { var resultDiv = document.getElementById('con-result');
var hourlyRate = parseFloat(document.getElementById('con-hourly-rate').value); var hoursPerWeek = parseFloat(document.getElementById('con-hours-per-week').value); var weeks = parseFloat(document.getElementById('con-weeks').value); var overheadPct = parseFloat(document.getElementById('con-overhead').value); var profitPct = parseFloat(document.getElementById('con-profit').value); var expenses = parseFloat(document.getElementById('con-expenses').value);
// Validation var errors = []; if (isNaN(hourlyRate) || hourlyRate 200) errors.push("Overhead Rate seems unusually high (max 200%)."); if (profitPct > 100) errors.push("Profit Margin cannot exceed 100%.");
if (errors.length > 0) { resultDiv.innerHTML = '' + errors.join('') + ''; return; }
// Core calculations var totalHours = hoursPerWeek * weeks; var baseLaborCost = hourlyRate * totalHours; var overheadCost = baseLaborCost * (overheadPct / 100); var subtotal = baseLaborCost + overheadCost; var profitAmount = subtotal * (profitPct / 100); var contractValue = subtotal + profitAmount + expenses;
// Derived metrics var effectiveRate = contractValue / totalHours; var laborPct = (baseLaborCost / contractValue) * 100;
var fmt = function(n) { return n.toLocaleString('en-US', {minimumFractionDigits: 2, maximumFractionDigits: 2}); };
resultDiv.innerHTML = 'Contract Value Breakdown' + '' + 'Total Hours' + fmt(totalHours) + ' hrs' + 'Base Labor Cost$' + fmt(baseLaborCost) + '' + 'Overhead (' + overheadPct + '%)$' + fmt(overheadCost) + '' + 'Subtotal (Labor + Overhead)$' + fmt(subtotal) + '' + 'Profit (' + profitPct + '%)$' + fmt(profitAmount) + '' + 'Reimbursable Expenses$' + fmt(expenses) + '' + '' + 'Total Contract Value$' + fmt(contractValue) + '' + 'Effective Billing Rate$' + fmt(effectiveRate) + '/hr' + 'Labor as % of Contract' + laborPct.toFixed(1) + '%' + ''; }
#### Formula
Total Hours = Hours per Week × Contract Duration (weeks) Base Labor Cost = Hourly Rate × Total Hours Overhead Cost = Base Labor Cost × (Overhead Rate / 100) Subtotal = Base Labor Cost + Overhead Cost Profit Amount = Subtotal × (Profit Margin / 100) Total Contract Value = Subtotal + Profit Amount + Reimbursable Expenses Effective Billing Rate = Total Contract Value / Total Hours
