NC Licensed Contractor Verification Cost Savings Calculator

Estimate how much money you save by verifying a contractor's NC license before hiring — factoring in avoided rework costs, fines, legal fees, and project delays.

Total Project Cost ($)

Full contracted value of the construction or renovation project.

Estimated Rework Cost if Unlicensed (% of project)

Industry average: 20–35% of project cost for substandard work requiring correction.

Probability of Code Violation Fine (%)

Likelihood of receiving a fine when using an unlicensed contractor. NC NCLBGC data suggests 30–60% risk.

Average NC Code Violation Fine ($)

NC General Statute §87-14 fines range from $500 to $5,000 per violation; defaults to $5,000.

Probability of Legal Dispute (%)

Estimated chance of a legal dispute arising from unlicensed contractor work.

Average Legal/Dispute Resolution Cost ($)

Typical attorney fees + court costs for contractor disputes in NC: $3,000–$15,000.

Expected Project Delay if Issues Arise (days)

Number of additional days lost to rework, inspections, or legal proceedings.

Daily Cost of Project Delay ($/day)

Include carrying costs, lost rent, business interruption, or temporary housing costs.

Cost to Verify Contractor License ($)

NC NCLBGC online verification is free. Third-party background checks may cost $25–$150.

Calculate Savings

function ncCalc() { // --- Grab inputs --- var projectCost = parseFloat(document.getElementById('nc-project-cost').value); var reworkPct = parseFloat(document.getElementById('nc-rework-pct').value); var fineRisk = parseFloat(document.getElementById('nc-fine-risk').value); var avgFine = parseFloat(document.getElementById('nc-avg-fine').value); var legalRisk = parseFloat(document.getElementById('nc-legal-risk').value); var legalCost = parseFloat(document.getElementById('nc-legal-cost').value); var delayDays = parseFloat(document.getElementById('nc-delay-days').value); var dailyCost = parseFloat(document.getElementById('nc-daily-cost').value); var verifyCost = parseFloat(document.getElementById('nc-verify-cost').value);

// --- Core Formulas --- // 1. Expected rework cost (probability-weighted) // Assumption: rework is near-certain (100%) if unlicensed contractor is used and issues arise; // we treat reworkPct as the fraction of project cost lost to substandard work. var reworkCost = projectCost * (reworkPct / 100);

// 2. Expected fine cost = fine_probability * average_fine var expectedFineCost = (fineRisk / 100) * avgFine;

// 3. Expected legal cost = legal_probability * average_legal_cost var expectedLegalCost = (legalRisk / 100) * legalCost;

// 4. Expected delay cost = delay_days * daily_cost var delayCost = delayDays * dailyCost;

// 5. Total expected risk cost (without verification) var totalRiskCost = reworkCost + expectedFineCost + expectedLegalCost + delayCost;

// 6. Net savings from verifying = total risk cost avoided - cost of verification var netSavings = totalRiskCost - verifyCost;

// 7. Return on Investment of verification // ROI = (Net Savings / Verification Cost) * 100 [if verifyCost > 0] var roi = (verifyCost > 0) ? (netSavings / verifyCost) * 100 : Infinity;

// 8. Savings as % of project cost var savingsPct = (netSavings / projectCost) * 100;

// --- Format helpers --- function fmt(n) { return n.toLocaleString('en-US', {style:'currency', currency:'USD', maximumFractionDigits:0}); } function fmtPct(n) { return isFinite(n) ? n.toFixed(1) + '%' : 'N/A (free verification)'; } function fmtRoi(n) { return isFinite(n) ? n.toLocaleString('en-US', {maximumFractionDigits:0}) + '%' : '∞ (free verification)'; }

#### Formulas Used

Rework Cost = Project Cost × (Rework % ÷ 100)

Expected Fine Cost = Fine Probability × Average Fine

Expected Legal Cost = Legal Dispute Probability × Average Legal Cost

Delay Cost = Delay Days × Daily Cost of Delay

Total Risk Cost = Rework Cost + Expected Fine Cost + Expected Legal Cost + Delay Cost

Net Savings = Total Risk Cost − Verification Cost

Verification ROI = (Net Savings ÷ Verification Cost) × 100
