Cost per lead is the wrong number. Judge your mortgage ads by funded files.
The cheapest leads are often the most expensive ones. How to follow each ad campaign from spend to funded file, and what to watch in the 30–90 days before files fund.
Judge mortgage ads by cost per funded file, not cost per lead: total campaign spend divided by the files that campaign funded. Ad platforms only see leads, so you have to tag each lead with its campaign and record whether it funded. Until files fund (30–90 days), watch cost per lead together with how many leads score Hot or Warm.
Why is cost per lead misleading for mortgage ads?
Every ad platform tells you what a lead cost. None of them can tell you what a funded loan cost, because they never see the file fund. In our demo brokerage, one campaign brings leads in at $77 each and has funded nothing in 90 days. Another costs twice as much per lead, $157, and funds a file for every $1,805 spent. Judged by cost per lead, you would cut the one that funds and keep the one that doesn’t.
Demo numbers, from a fictional brokerage. The point is the shape: cost per lead and cost per funded file can rank the same campaigns in opposite order.
How do you calculate cost per funded file?
- Read the spend. Connect Google Ads or Meta. Broker AI reads spend and leads campaign by campaign, every day. Reading never changes anything in your account.
- Tag the lead. When a lead comes in, tell your AI where it came from: “This lead came from my Spring Renewals campaign on Facebook.” That sentence ties the file back to the money that produced it.
- Log the outcome. When the file funds, or doesn’t, your AI records it. No client names, just the stage and a revenue range.
- Divide. Spend on the campaign over the period, divided by files from that campaign that funded. The Ads page shows it by campaign, next to cost per lead.
What should you watch before files fund?
Funded files take 30 to 90 days to show up. Until then, two numbers carry the weight: cost per platform lead, which you have on day one, and how many leads came in Hot or Warm when your AI scored them against your own rubric. If you have last year’s leads in a spreadsheet, import them and the funded numbers start from your history.
Does Broker AI change my ads?
It suggests changes from your own numbers: pause a campaign that spends without funding, stop paying for Google searches that never turn into leads, move budget toward what funds. Nothing changes in your ad account until you approve that specific change. It never spends a dollar on its own.
Questions people ask
- What is a good cost per funded loan for mortgage ads?
- It depends on your market, loan size and compensation, so compare campaigns against each other and against your own referral channels rather than a published benchmark. A campaign is worth keeping when its cost per funded file is comfortably below what a funded file earns you.
- Why don’t Google or Meta report funded loans?
- They only see the click and the form fill. Whether the file funds lives in your CRM or loan system, so someone has to connect the lead to its campaign and record the outcome. Broker AI does that without storing client details.
- How long until I can see cost per funded file?
- Usually 30–90 days from the first tagged lead, because that is how long files take to fund. Importing past leads with their campaigns gives you the number on day one.
