LED Savings Calculator
See what switching to LED really saves. Pick the old bulb (or set the watts), the LED wattage, how many bulbs, hours per day and your tariff — and get the money and units saved, plus the payback. It’s usually one of the fastest paybacks in the home.
931 units/year saved · 51 W less per bulb × 10 bulbs.
The LEDs usually pay for themselves in months, then keep saving for years — and last far longer, so you replace them less often too. Buy quality ISI-marked LEDs.
Indicative. Assumes each bulb runs the set hours daily at the stated wattages and tariff, and a flat LED price; real figures vary with usage, tariff slabs and bulb quality. It ignores the extra saving from LEDs’ far longer life (fewer replacements), so the real benefit is usually larger.
