About AutoLoanMath: The Math Behind Going Green

We are the spreadsheet nerds who ruin sales pitches.

If you are looking for a blog that tells you to "save the planet at any cost," you are in the wrong place.

AutoLoanMath exists for one reason: To protect your wallet from bad math.

The "Green Energy" industry is filled with aggressive sales tactics, inflated ROI promises, and "payback periods" that assume electricity prices will triple overnight. We don't play that game. We believe that energy efficiency is a financial decision, not an emotional one.

Our Core Philosophy: ROI First

If a product doesn't pay for itself within its warranty period, we will tell you not to buy it.

  • We Love: Heat Pumps, Smart Plugs, and DIY Insulation. (High ROI).
  • We Hate: $25,000 Window Replacements and "Eco-Friendly" gadgets that save $2 a year. (Negative ROI).

Where We Get Our Data

We do not guess. Every calculator and article on this site is built using verified data from:

  • The IRS: For accurate Tax Credit (Form 5695) limits and loopholes.
  • Energy.gov: For average appliance wattage and efficiency standards.
  • U.S. Bureau of Labor Statistics: For historical electricity inflation rates.
  • Real Contractor Quotes: For actual installation costs in 2025 (not 2010 estimates).

Editorial Policy: Unbiased & Brutal

We are an independent publisher.

  1. No Pay-to-Play: Solar companies cannot pay us to change our math.
  2. Affiliate Disclosure: We may earn a commission if you buy a smart plug we recommend (like the Kasa HS103), but we will never recommend a product that doesn't save you money.
  3. The "Tough Love" Rule: We promise to tell you the truth about costs, even if it hurts. If leaving your Gaming PC on costs $150/year, we’ll say it. If your solar battery is a luxury toy, we’ll say that too.
