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 5000-watt generator in terms of both upfront and running costs. For our analysis, we chose the best 5000-watt generator available in the market.

**The upfront cost of a 5000-watt generator, which includes the generator, transfer switch, inlet box, cord, and labour installation, will cost you around $3045 for a single fuel, $3044 for dual fuel, and $3655 for an inverter generator. The running cost will be $4.2/day for traditional, and $2.5/day for inverter generators if you run it daily for three hours at half load.**

**Upfront Cost **

The upfront cost is the cost of the generator, related accessories, and installation that you have to bear. We calculated the cost of each component involved in the installation process and then summed it up for a total estimated cost.

**Generator Cost **

The cost of a generator also varies due to various factors, such as single or dual fuel, standby or portable generator, and build quality or extra features such as CO sensor, remote start, etc.

**High Rated Cord **

Cord | Approximate Cost |
---|---|

Best brose 50Ft 50 Amp | $210 |

CircleCord 5pft 50A | $229 |

Rvingpro 50Amp | $219 |

The best cord will cost you around $219, which ranges between $210 and $229.

So, the **total upfront cost of a 5000-watt generator** will be, on average, $3045 for a single-fuel generator, $3044 for a dual-fuel generator, and $3494 for an inverter generator.

**Running Cost **

If we assume that you will run the generator for 3 hours on a daily basis at half load, then what will be the fuel cost? Let’s suppose the price of gasoline is $3.84 per gallon.

**Fuel Cost**

Generator | Gasoline Runtime | Propane Runtime |
---|---|---|

DuroMax XP5500E | 2.5 hrs/gal at half load | |

Champion 200921 | 2.9 hrs/g at half load | |

JEGS 86065 Portable Generator | 2.5 hrs/gallon at half load | |

Green-Power America 5000W | 2.75 hrs/g at half load | |

Pulsar 5250W Dual Fuel | 3 hrs/g at half load | 0.6 hrs/pound at half load |

WEN DF475T Dual Fuel | 2.75 hrs/g at half load | 0.5 hrs/pound at half load |

DuroMax XP5500EH | 2.5 hrs/g at half load | 0.5 hrs/pound at half load |

Westinghouse iGen4500 | 5.2 hrs/gallon at half load | |

Duromax xp4500ih | 6 hrs/gallon at half load | |

Pulsar Products PG4500iSR | 4 hrs/gallon at half load | |
