A portable generator typically costs around $500 to $1,800 without installation.

Home standby generators typically cost around around $3500 to $6200 without the extra installation costs.

What size your generator is, what fuel types it can use, and whether your portable generator has a built-in inverter will influence the prices a lot.

Additionally, installing a portable generator at home will cost around $900 to $4,000, and installing a standby generator at home costs around $3,000 to $5,000.

You want to keep the long term costs of generators in mind too. This includes things like maintenance and fuel.

For example, it will cost around $0.35 to $4.8 an hour to run a generator depending on your fuel type choice, machine, and load.

You can find more precise generator costs for different power levels, models, fuel types, and rental prices in the rest of the article.

How much does a portable generator cost?

A portable generator typically costs around 500 USD to 1800 USD depending on its size and features like a built-in inverter or dual fuel capability.

Small portable generators typically cost around 500 USD to 1000 USD.

Medium inverter generators often cost around 900 USD to 1400 USD.

Large non-inverter generators are often around the 900 USD to 1400 USD range too.

In certain categories like large dual fuel inverter generators, you can even expect to invest 1800 USD to 2500 USD in your machine.

How much does a small portable generator cost?

A small portable generator typically costs around $500 to $1000. Machines like this have up to around 3000 peak watts.

The best small generators tend to be inverter generators so you don’t have to worry about the price difference for this feature.

How much does a medium portable generator cost?

A medium portable inverter generator typically costs around $900 to $1400.

Medium non-inverter generators tend to cost around $500 to $1000 so if you don’t need to power sensitive electronics you can save some money.

This range of medium portable generators includes machines with 3500 to 6500 peak watts.

How much does a large portable generator cost?

Large portable generators typically cost around $1100 to $1800 but there are definitely some bigger and more expensive models too.

For generators from 7000 to 12000 peak watts, this range will mostly hold up.

Additionally, keep in mind that this range is for non-inverter machines since the best large portable generators tend to be in this category.

Large inverter generators will often be around $2000 to $2500 although there are exceptions too.

For large non-inverter generators of 15000 peak watts, you can expect to invest $2000 to $3000.

How much does a generator cost for a house?

A home standby generator will typically cost around 3500 USD to 6200 USD depending on how much power you want.

Portable generators for a house tend to cost around 1100 USD to 2200 USD but these generally offer fewer watts than standby machines too.

The cost of a generator for a house will ultimately vary a lot due to what appliances you want to power during an outage and details like your fuel preferences.

How much does a portable generator cost for a house?

A portable generator for a house typically costs around $1100 to $2200 depending on how big you want to go.

You may find a 4500 peak watt generator enough to run your most essential home appliances. In that case, the cost would be around $800 to $1000.

How much does a standby generator cost for a house?

A standby generator for a house typically costs around 3500 USD to 6200 USD.

The size of your house and what appliances you plan to run will influence the actual price a lot.

It can be worth getting a relatively small standby generator if you only have to deal with a few short power outages a year.

How much is a generator for a 1,500 sq ft house?

A standby generator for a 1,500 sq ft house is around $3700 to $5000 assuming you will need about 12,000 to 15,000 peak watts.

Keep in mind that you will have additional installation costs too.

Additionally, you may prefer the lower cost of a smaller generator and run fewer appliances during an outage.

How much is a generator for a 2,000 sq ft house?

A standby generator for a 2,000 sq ft house is around $4700 to $5700 assuming you will need about 14,000 to 18,000 peak watts.

Again, your exact home appliance setup will decide whether you actually need this size of standby generator.

You could be able to get a more budget-friendly generator and survive the power outages anyway.

How much is a generator for a 3,000 sq ft house?

A standby generator for a 3,000 sq ft house is around $5700 to $6200 assuming you will need about 18,000 to 25,000 peak watts.

The stronger standby generators generally vary less in terms of price.

How much does a generator cost to run?

At the time of writing, it costs around $0.35 to $4.8 an hour to run a generator depending on your fuel type choice, machine, and load.

A gasoline portable generator will cost around $0.5 to $1.6 an hour to run at 25% load.

Running a portable propane generator at 25% load will cost around $0.5 to $1.3 an hour at the time of writing.

Propane standby generators will cost around $2.4 to $4.8 an hour to run at 50% load.

Running natural gas standby generators will typically cost around $0.35 to $0.7 an hour at 50% load.

How much fuel a generator uses still varies a lot between different models but these general numbers do give you an idea of the cost to run a generator.

How much does it cost to run a generator per day?

Running a generator costs around $8.4 to $115.2 a day depending on what fuel types, machines, and engine loads you choose.

A portable gasoline generator will cost around $12 to $38.4 to run for a day at 25% load.

Running a portable propane generator at 25% load for a day will cost about $12 to $31.2.

A standby propane generator will cost around $57.6 to $115.2 to run for a day at 50% load.

Running a natural gas standby generator at 50% load for a day will cost around $8.4 to $16.8.

You do want to keep the limits of how long a generator can run continuously in mind. Running a portable generator for 24 hours is often too much.

How much does it cost to install a generator at your house?

How much does a generator cost for an RV?

A generator for an RV costs around $550 to $1300 depending on the size of your home on wheels and the devices in them.

You typically want a good inverter generator for RVs since you will likely want to power sensitive electronics like a fridge, an RV AC, and a phone.
