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.

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.
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.

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.
|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|
|GENMAX 5500 Inverter||3.5 hrs/gallon at half load|
According to the table above, on average, a traditional generator will consume 2.71 hrs/gallon at half load, and an inverter generator will consume 4.6 hrs/gallon.
Therefore, the traditional 5000-watt generator will consume 1.1 gallons of fuel per day, which will cost you $4.2 per day and $127 per month if you run the generator for 3 hours daily at half load.
The inverter 5000-watt generator will consume 0.65 gallons of fuel per day, which will cost you $2.5 per day and $75 per month if you run the generator for 3 hours daily at half load.
