Estimates based on inputs provided. Actual savings vary by usage patterns, utility rate schedules, and equipment. CO₂ calculations use the EPA national average grid emissions factor (0.386 lbs/kWh). Rate auto-fill uses estimated residential all-in rates sourced from NYSERDA IEDR (iedr.nyserda.ny.gov/rate-plan/) and EIA Electric Power Monthly (April 2026); verify your exact rate on your utility bill. Results do not constitute a professional energy audit.

LED Lighting Savings Calculator — Frequently Asked Questions

How does this LED lighting savings calculator work? +
This LED lighting savings calculator computes the annual watt-hour difference between your current bulbs and LED replacements, multiplies by your electricity rate, and adds lamp replacement cost savings from longer LED lifespan. A typical 60W incandescent replaced with a 9W LED saves roughly 51W per bulb — about $8–12/year per bulb at Northeast electricity rates.
What’s the payback period for switching to LED? +
At current LED prices ($3–8/bulb) and Northeast electricity rates ($0.18–0.24/kWh), payback is typically 6–18 months for bulbs running 4+ hours daily. High-use fixtures — kitchens, living rooms, offices — pay back fastest. Garage and closet lights that run only minutes per day may take several years. The LED lighting savings calculator shows payback for your specific usage profile.
Are there rebates for residential LED lighting? +
Yes — the 25C tax credit covers LED bulbs that meet ENERGY STAR requirements at 30% of cost up to $1,200. Many Northeast utilities also offer instant rebates on ENERGY STAR LEDs at participating retailers — typically $1–5/bulb. Use the Northeast Rebate Finder to see current utility programs in your area.
