How to Budget for a Standby Generator

Keep the lights on during outages without draining your savings by timing the install right and spreading out the cost.

Typical cost $6,000 before anything else
Across the 0% window $400.00/mo 15 months, no interest

How we got that: $6,000 spread evenly across the 15-month introductory window on the Discover it® Cash Back. Checked · at the bank Carry a balance past the window and the standard APR applies to what is left.

When the grid goes down, your house stays warm, the fridge keeps running, and you don't have to lift a heavy portable unit in the dark. The actual install takes about one to three days, usually involving a concrete pad, a gas line hookup, and an electrical transfer switch. Doing this outside of storm season means contractors have open schedules and you might avoid peak-demand pricing.

Before you commit, get at least three quotes from licensed local electricians. Prices swing wildly for whole-house systems, and you want to compare how they handle permits and gas lines.

The 0% intro APR for 15 months on purchases and balance transfers is a deadline, not free money, so any balance left when that window ends will start accruing standard interest.

The steps

  1. 01

    Get multiple quotes

    Call three local contractors to price out the unit, pad, and permits. Make sure each quote includes the electrical transfer switch so you aren't hit with surprise add-ons later.

  2. 02

    Time the install

    Book the work during the off-season when storms aren't threatening your area. Contractors are slower right now, which gives you more leverage on labor costs.

  3. 03

    Line up the payments

    Spreading the typical $6000 cost across the 15-month intro window on your Discover it® Cash Back card works out to about $400.00 per month.

  4. 04

    Schedule the inspections

    Your city will need to sign off on the electrical and gas hookups. Make sure your contractor includes pulling those permits in their final price.

  5. 05

    Test the system

    Set the generator to run a weekly self-test cycle. Catching any issues early means it will actually turn on when the power cuts out.

  6. 06

    Check the card terms before you commit

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

Common questions

How long does a whole-house generator last?

Most units last between 20 and 30 years if you keep up with routine maintenance like oil and filter changes. They run a short weekly self-test to make sure the engine stays healthy.

Does a standby generator run on natural gas or propane?

It can run on either, depending on what is already hooked up to your house. Natural gas is usually cheaper to run continuously, while propane tanks require manual refills.

Do I need a permit for the installation?

Yes, almost every city requires electrical and plumbing permits for a permanent generator. Your contractor should handle pulling these as part of the job.

Will it power my whole house at once?

That depends on the wattage you buy and whether you use a load-shedding module. Smaller units power essential circuits, while larger ones run central air and everything else.
