How to Calculate IRA Clean Energy Credit
What is IRA Clean Energy Credit?
The IRA Clean Energy Credit Calculator helps homeowners and businesses determine which Inflation Reduction Act tax credits and rebates they qualify for across solar, heat pumps, EVs, batteries, and energy efficiency improvements.
Formula
Total Available Credits = Solar ITC (30%) + Heat Pump Credit ($2,000) + EV Credit ($7,500) + Efficiency Credits ($1,200/yr) + Electrification Rebates
- ITC
- Investment Tax Credit (%) — Percentage credit for solar, battery, and other clean energy investments
- Cap
- Annual Credit Cap ($) — Maximum credit claimable per tax year per category
- MAGI
- Modified Adjusted Gross Income ($) — Income used to determine eligibility for income-limited rebates

Worked Examples
Input
Solar system $24,000 + heat pump $8,000 + EV $45,000 + insulation $2,000
Result
Solar ITC: $7,200 + Heat pump: $2,000 + EV: $7,500 + Insulation: $1,200 = $17,900 total credits
Input
Heat pump water heater $2,500 + electrical panel upgrade $4,000
Result
HP water heater: $2,000 credit + panel: $600 credit = $2,600 (within $3,200 electrification cap)
Common Mistakes to Avoid
- ✕Not realizing the $1,200 annual cap on 25C efficiency credits resets each year — spread improvements across tax years
- ✕Confusing the heat pump $2,000 credit (separate from the $1,200 efficiency cap) with the general efficiency credits
- ✕Missing that low-to-moderate income households qualify for separate HOMES and HEAR rebate programs up to $14,000
Frequently Asked Questions
How much can I save total with IRA clean energy credits?
