How to Pay for a Standby Generator

Keep your lights on and your fridge running during storm season with an 18-month interest-free plan.

Typical cost $7,000 before anything else
Across the 0% window $388.89/mo 18 months, no interest

How we got that: $7,000 spread evenly across the 18-month introductory window on the Citi Simplicity® Credit Card. Checked · at the bank Carry a balance past the window and the standard APR applies to what is left.

When the power goes out, your life usually stops. A whole-home standby generator kicks in automatically within seconds, keeping your AC, fridge, and Wi-Fi running like nothing happened. Fall is the sweet spot to get this done because contractors are less busy than in the summer heat, and you want the work finished before winter storms hit. The installation takes about one to two days, but you need to start early and get at least three quotes from local pros to ensure you get a fair price.

A solid system runs about $7,000 once you factor in the unit and the professional installation. Instead of draining your savings all at once, we can split this into manageable monthly chunks. By using a specific credit card, you can pay it off over a year and a half without paying a penny of interest.

Here is the catch: that 0% for 18 months on purchases and balance transfers from date of account opening is a hard deadline, not a gift. If you still have a balance left when the 18 months are up, the remaining amount will start racking up interest at the standard variable rate. Pay it off on time, or the deal turns expensive.

The steps

  1. 01

    Get three quotes

    Do not settle for the first estimate you get. Call at least three local installers in late summer or early fall. Ask them to detail the permits, trenching, and hookup fees in their bids so you can compare them apples-to-apples.

  2. 02

    Choose your fuel source

    Most standby generators run on natural gas or liquid propane. If you already have a natural gas line, hooking into it is usually the cheapest and easiest route. If not, you will need to budget for a propane tank installation on your property.

  3. 03

    Secure the card

    Apply for the Citi Simplicity® Credit Card to help carry the cost. This card gives you 0% for 18 months on purchases and balance transfers from date of account opening. That is your interest-free runway to pay off the project.

  4. 04

    Do the math

    If your total installation cost comes out to $7,000, you need to pay $388.89 per month to hit zero before your time is up. Set up autopay for this exact amount immediately so you do not have to think about it.

  5. 05

    Schedule the install

    Once your card arrives, book the contractor for early fall. The installation takes a couple of days and involves some noisy drilling and brief power outages. Doing this before storm season means you will be ready when the weather turns.

  6. 06

    Check the card terms before you commit

    Every figure we publish for the Citi Simplicity® Credit Card carries the date a person verified it against Citi and a link to where they checked. Intro windows and APRs change without notice, so confirm the current terms before applying.

Common questions

Does a standby generator add value to my home?

Yes, it usually does. Buyers love seeing a professional backup system, especially in areas prone to storms or rolling blackouts. You will likely recoup a good chunk of the cost when you sell.

What size generator do I actually need?

It depends on what you want to run. A 20kW to 22kW generator can power a typical medium-sized home, including the central air conditioning. Your installer will calculate your peak electrical load to find the right size.

How long does a standby generator last?

With regular maintenance, a good standby generator lasts about 20 to 30 years. You will need to have it serviced annually, similar to your home HVAC system.

Can I install a standby generator myself?

No, this is not a weekend DIY project. It requires permits, professional gas line plumbing, and advanced electrical work to connect a transfer switch to your main panel. Leave this one to the pros.
