NECA (National Electrical Contractors Association) Manual of Labor Units — industry-standard spine for electrical labor-time estimation
Electrical Service Call Pricing Calculator
Build a defensible flat-rate price for a residential or light-commercial electrical service call from first-principles cost inputs: dispatch fee, journeyman + helper labor minutes anchored to the NECA Manual of Labor Units, loaded labor cost (with payroll tax under 26 USC § 3121, benefits, NCCI class code 5190 workers'-comp), materials at contractor cost with markup, per-call vehicle and overhead allocation, and target net margin applied as a divisor. Computes the recommended flat-rate price, T&M-equivalent hourly rate, dispatch-fee cost-recovery floor, and breakeven calls per electrician per day. Tool, not advice — for binding price-book adoption, commission a NECA or IEC cost-of-doing-business analysis; for tax treatment of vehicle depreciation and payroll-tax components, consult a licensed CPA familiar with construction-services tax practice.
NFPA 70 (National Electrical Code) Article 230 (Services — number of services
Electrical Panel Upgrade Bid Calculator
Build a defensible bid for a residential service panel upgrade (100A to 200A, 200A to 400A, like-for-like panel swap) from first-principles material, labor, and code-compliance inputs. Computes panel material cost (Square D Homeline / QO, Eaton CH / BR, Siemens / Murray), service-entrance conductor cost (SER / SEU sized per NEC 230.42 and 310 ampacity tables), labor hours (NECA Manual of Labor Units anchored), utility and inspection coordination, permit fee, and grounding-electrode-system upgrade per NEC 250.50-66 and 250.94 intersystem bonding. Outputs the recommended bid at target margin (margin as divisor), bid per amp, and NEC 408.36 ground-fault-protection advisory. Tool, not advice — actual bid must be tailored to site conditions; for tax treatment of fully-loaded cost components, consult a licensed CPA.
NFPA 70 (National Electrical Code) Article 625 (Electric Vehicle Power Transfer System) — §625.41 continuous-load sizing (125% of EVSE rated input)
EV Charger Installation Pricing Calculator
Build a defensible bid for a Level 2 EV charger (EVSE) installation at single-family or HOA-common-area locations from first-principles material, labor, and code-compliance inputs. Computes branch-circuit sizing under NEC 625.41 (125% continuous-load multiplier), conductor sizing per NEC 310.16, charger material cost by model (Tesla Wall Connector, ChargePoint Home Flex, Wallbox Pulsar Plus, Emporia, Grizzl-E), branch-circuit material (wire, conduit, breaker, NEMA 14-50 receptacle or hardwired termination), and labor hours from the NECA Manual of Labor Units. Surfaces the NEC 625.42 disconnect advisory, NEC 625.54 GFCI requirement, NEC 220 load-calculation advisory, and a NEMA receptacle vs hardwired comparison. Tool, not advice — actual bid must be tailored to site conditions and a verified NEC 220 load calculation.

Electrical Flat-Rate Pricing Calculator
Builds a flat-rate residential electrical price from NECA labor units — the industry-standard estimating method for electricians. Converts labor units to hours using configurable minutes-per-unit, applies the fully-loaded technician cost, adds materials at markup and overhead per labor hour, then divides by (1 − target margin) to produce the flat-rate price. Returns the recommended price, labor hours, labor cost, materials customer-facing price, break-even price, and realized margin. Benchmarked against NECA (National Electrical Contractors Association) Manual of Labor Units and cost-of-doing-business guides.
Generator Installation Pricing Calculator
Quotes a residential standby generator installation: generator unit + transfer switch + permits + optional gas line coordination + labor. One of the highest-revenue residential electrical jobs at $5,000-$20,000 depending on kW class, transfer switch type, and site conditions. Builds the customer-facing price from materials at contractor cost with markup, labor at the loaded electrician rate, and permit and gas line passthroughs, with a target gross margin applied to the labor component. Benchmarked against NECA (National Electrical Contractors Association) and NFPA 70 (NEC) Article 702/445.
Electrical Service Agreement Pricing Calculator
Prices an annual residential electrical maintenance agreement covering panel inspection, GFCI/AFCI testing, smoke and CO detector check, and arc-fault review — recurring revenue for electrical contractors. Builds the recommended annual price from labor cost per visit (technician loaded rate × visit time), parts and consumables, overhead per visit, and a target gross margin applied as a divisor. Compares the result against a competitor benchmark. Benchmarked against NECA (National Electrical Contractors Association) and IEC (Independent Electrical Contractors) operations benchmarks.
Electrical Estimating Labor Hours Calculator
Estimates total field labor hours for a residential or light-commercial electrical project using simplified labor-unit inputs for six common task categories — receptacle rough-in, switch rough-in, light fixture rough-in, panel circuits, service upgrades, and low-voltage runs — anchored to NECA Manual of Labor Unit defaults. Returns the total estimated hours and labor cost at the fully-loaded electrician rate. Helps electricians build faster, more consistent estimates for new construction and renovation projects.
EV Charger Installation Profitability Calculator
Calculates job profitability for a Level 2 EV charger installation — the fastest-growing residential electrical job category. Presents the job as a product-plus-install sale: charger unit at contractor cost with markup, labor at the fully-loaded electrician rate, optional panel upgrade cost passthrough, and permit fee passthrough, with a target gross margin applied to the labor component. Benchmarked against NECA (National Electrical Contractors Association) guidelines, NFPA 70 Article 625, and DOE AFDC national average installation cost data.
