Los Angeles · KFI AM 640
The station most Los Angeles advertisers ask for by name, and one of the easiest to buy badly. Berk Marketing buys KFI for advertisers and represents no station in this market.

Short answer. KFI is a 50,000 watt clear channel news and talk station on 640 AM, owned by iHeartMedia, and it covers Southern California from a single signal. Because it is a talk station, it takes fewer commercials a day to reach a listener than a music station in the same market does. The practical entry point for a Los Angeles schedule is around five thousand dollars a week, and most advertisers should be buying it on remnant, which is typically 40 to 60% off the published rate card. The thing that decides whether the buy works is not how many spots you run, it is whether the schedule was built for the way people listen to this station.
The argument, made literally
Most people who tell you talk radio works differently are repeating something they read. This is the version where the person saying it sold classical, hip hop, country and talk in Los Angeles, on air and in sales, before ever representing an advertiser.
That matters on a station like KFI for one specific reason. A talk station sells a very different listening state from a music station, and the schedule that suits one will waste money on the other. Knowing which is which is not a theory here, it is a job he did.
The full career, nine formats and a dozen stations, on air and in sales, before ever representing an advertiser.
The idea that changes a schedule
A news and talk listener is engrossed. They are following a topic or a conversation, closer to story time than to background noise. Because they are genuinely listening, fewer commercials a day will do the job, and a commercial written to keep that same conversational delivery gets far more information across than a hard sell will.
The listener is tuned in but only half attending, which is how music radio is used and there is nothing wrong with it. It does mean you need considerably more frequency before a message penetrates. A schedule built for KFI will look thin on a music station, and a schedule built for a music station will overspend on KFI.
This is the single most common way a Los Angeles buy goes wrong. An advertiser is sold the same weight across a talk station and three music stations because the plan was built from a budget rather than from how each station is actually heard.
Before you sign anything
KFI’s rate card is an opening position, not a price. What actually decides what you pay:
Morning and afternoon drive on a Los Angeles talk station are the most contested inventory in the market. What sits either side of your spot matters more on talk than on music, because the listener is paying attention to what is around it.
Demand on a station this size moves week to week. The same schedule quoted in two different weeks is not the same negotiation, and a rate that was unavailable in October can be available in January.
Sixty seconds on a talk station often outperforms thirty, because the format supports a longer conversational read. That is a creative decision that changes the media cost, so it belongs in the conversation before the buy, not after.
This one is not about price at all, and it is the one advertisers do not see coming. See below.
The rule that costs advertisers the most
If you contact KFI directly and a seller quotes you a rate, that quote follows you. Once a station has your name against a number, an agency coming in behind you has very little room to negotiate on your behalf, and in many cases we will not be able to represent you on that station at all.
There is nothing improper about it, it is simply how station credit and account assignment work. It is also completely avoidable, and it costs nothing to avoid. One call before you make any other call is the whole of it.
Berk Marketing represents advertisers. It owns no stations, sells no inventory and is paid by the advertiser, not by iHeartMedia. The station list on any plan starts from who reaches your customer, not from who is paying us.
We will run a competitive monitoring report at no charge and with no obligation. It shows which stations your competitors are on, at what times of day, how many spots, and it includes the actual audio of their commercials.
In many cases nothing shows up at all, and that is worth knowing too. You have to start by knowing what others are doing.
Get the ReportThe way most advertisers should buy this station
A commercial break with an unsold unit in it earns the station nothing. Stations would far rather sell that unit quietly and cheaply than let it run empty, and that unsold inventory is what remnant buying is. It is not a lesser class of airtime. It is the same stations and the same dayparts that full-rate advertisers buy, priced differently because you are flexible about exactly when your spot lands. In practice that is typically 40 to 60% off the published rate card.
The budget is placed before anything airs. That is what buys the access to the discounted inventory in the first place.
We aim at Monday to Friday, 6am to 7pm, which is the part of the day worth having on a station like KFI. Weekends and evenings are available too. Then we track what actually clears.
The station reports back. If a spot was preempted, you do not pay for it. It is refunded or carried into the next flight, your choice.
That last point is the part advertisers usually miss. The exposure on remnant is uncertain, the money is not. You are never billed for a spot that did not run.
You cannot know your exact airtimes in advance. Remnant is placed on the fly, and if the station sells that unit at full rate at the last minute, yours is the one that moves. You get a post log afterwards showing exactly when everything aired, so nothing about it is hidden. What you are trading is certainty of placement, and in return you buy considerably more weight for the same money.
You need fixed dates and times, your offer expires on a specific day, or you are tied to an event. Anything genuinely time-dependent should be bought at rate rather than on remnant, and we will tell you that rather than sell you a schedule that cannot deliver what you need.
Fit
You sell to adults who make decisions and want detail before they buy. Legal, financial, home services, healthcare, automotive and direct response offers all tend to work on this format, because a talk audience will sit through a sixty second explanation that a music audience will not. It also helps if you can handle Southern California volume when the phone rings.
Your offer needs a visual, your product is aimed at a young music audience, or your business cannot serve the whole KFI coverage area. A signal this large is only an advantage if you can actually use the reach. If you cannot, a smaller LA station will do more for the same money and we will say so.
Questions
There is no single answer and anyone who gives you one without asking questions is guessing. The rate depends on daypart, length, how many weeks you run and what inventory is unsold when you buy. The practical entry point for a Los Angeles schedule is around five thousand dollars a week. Below that the frequency is usually too thin to be heard.
KFI is a 50,000 watt clear channel station on 640 AM, which means it covers Southern California from one signal rather than needing several. At night the signal reaches considerably further. For an advertiser this cuts both ways: excellent value if you can serve the whole area, wasted reach if you serve one neighborhood.
It depends far more on your message than your budget. If your offer needs explaining, a talk station gives you a listener who will actually hear the explanation, and it takes fewer spots to do it. If your offer is simple and visual and aimed at a younger audience, a music station with a much heavier schedule will serve you better. The mistake is buying both with the same weight.
You can, and it will not do anything. Radio works on repetition inside a defined window. One spot on a station this size is a rounding error. If the budget only supports one spot, the honest advice is to save it until it supports a week.
No. Berk Marketing represents advertisers only and holds no station or network representation anywhere. That is the reason a plan can recommend against KFI when another station suits you better, and the reason it is worth calling before a station quotes you.
Tell us before anything else. Depending on how far it went we may still be able to work with you, but a direct quote already on record narrows what any agency can negotiate. It is the single most expensive thing an advertiser does without realizing it.
