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 75000-watt generator in terms of both upfront and running costs. For our analysis, we chose the best 7500-watt generator available in the market.
The upfront cost of a 7500-watt generator, which includes the generator, transfer switch, inlet box, cord, and labor installation, will cost you around $3485 for a single fuel, $3569 for dual fuel, $3844 for an inverter generator, and $4619 for a standby generator. The running cost will be $6.7 per day and $203 per month if you run it daily for three hours at half load.

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|
|ProMax 7500EA portable||1.6 hrs/gal at half load|
|WGen 60000 Westinghouse||1.96 hrs/g at half load|
|Powermate P0081400 PM7500||1.25 hrs/gallon at half load|
|Generac 7681 GP6500||1 hrs/g at half load|
|Ford 7,750W Portable Switch||1.6 hrs/g at half load|
|Pulsar PG7750B Dual Fuel||2 hrs/g at half load||0.65 hrs/pound at half load|
|DuroMax XP7500DX||1.8 hrs/g at half load||0.5 hrs/pound at half load|
|Champion Power Equipment 100520||2.5 hrs/gallon at half load|
According to the table above, on average, a generator will consume 1.7 hrs/gallon at half load. Therefore, the generator will consume 1.7 gallons of fuel per day, which will cost you $6.7 per day and $203 per month if you run the generator for 3 hours daily at half load.
|Generator||Air Filter Cost||Oil Capacity|
|ProMax 7500EA portable||$15||37 fl oz|
