Source-backed

Every cost driver is anchored to IRS, ENERGY STAR, DOE, EIA, BLS, NREL, LBNL, NEEP, ACCA, and ASHRAE data. Sources visible on every calculator.

All 200 sources

Planning ranges

Estimates are low / mid / high planning ranges, not contractor quotes. They reflect your state, panel size, install difficulty, and timing.

How we calculate

No funnel

No email gate. No phone form. No referral funnel. Just the numbers and the questions to ask your contractor.

Glossary of terms

How an ElectrifyCost estimate is built

  1. Step 1

    Equipment baseline

    Anchored to DOE / NREL benchmark studies and ENERGY STAR product data, with bands for trim level.

  2. Step 2

    Local labor & permits

    BLS Occupational Wage Statistics scaled by state cost-of-living, plus typical permit fees.

  3. Step 3

    Panel risk & complexity

    Probabilistic adders for panel upgrades, ductwork, condensate, and tight-space installs.

  4. Step 4

    Stack incentives

    Apply the federal 30C EV credit (through 2026-06-30), state programs, DOE Home Energy Rebates where launched, and utility offers. The federal 25C credit ended on 2025-12-31.

Deep dives by state

Two of our calculators have a dedicated page for every state, with local labor multipliers, retail electricity rates, climate zone, and state & utility rebates pre-applied. More modules are getting state pages over the coming months.
