The cost of the generator is a very important component in the buying process of a generator. The cost depends on various factors such as the brand, performance and build quality, type of generator, and advanced features such as remote start, CO sensor, and economy mode.

In this article, we have done our best to estimate the cost of a 3000-watt generator in terms of both upfront and running costs. For our analysis, we chose the best 3000-watt generator available in the market.

**The upfront cost of a 3000-watt generator, which includes the generator, transfer switch, inlet box, cord, and labor installation, will cost you around $2951 for a traditional single fuel, $3388 for a single fuel inverter, $3728 for a dual fuel inverter generator, and $4690 for a power station. The running cost will be $2.74 per day and $82 per month if you run it daily for three hours at half load.**
