LED Savings Calculator

Why Switch to LED Bulbs?

LED bulbs use far less electricity than incandescent, halogen, and many fluorescent bulbs. They also last much longer, which means fewer replacements over time. Our LED Savings Calculator compares total cost of ownership, including bulb purchases and electricity, so you can see real savings.

How Total Bulb Cost Is Calculated

The total cost over a period includes both electricity and replacement bulbs:

$$Total\ Cost = Electricity\ Cost + Bulb\ Replacement\ Cost$$

Electricity cost depends on wattage, daily usage hours, energy price per kWh, and the number of years. Replacement cost depends on bulb price and how many bulbs you need before they burn out.

For a fair comparison, pick bulbs that produce similar brightness. A 10 W LED often replaces a 60 W incandescent. Use our Electricity Cost Calculator to estimate running costs for other appliances too.

Understanding the Break-Even Point

LED bulbs usually cost more upfront but save money on electricity. The break-even point shows roughly how many months until the LED option becomes the cheaper choice compared to a traditional bulb over the same period.
