You’re spending money on leads. The question is whether that spend is making you money — and how much. Most mortgage teams track cost per lead. The ones who actually grow track cost per funded loan, return on ad spend, and lifetime value per lead source. Here’s how to build a measurement framework that tells you exactly which lead sources deserve more budget and which ones to cut.
The Four Metrics That Matter
1. Cost Per Lead (CPL)
What you pay for each lead. This is the starting point but not the finish line. A $25 CPL means nothing if none of those leads fund. A $150 CPL is a bargain if 8% fund into $4,000 revenue loans. CPL is a cost metric, not a performance metric. Track it, but don’t optimize for it alone.
2. Cost Per Funded Loan (CPFL)
Total lead spend ÷ number of funded loans from that source. This is the metric that determines profitability. If you spent $10,000 on leads from Vendor A and funded 4 loans, your CPFL is $2,500. If Vendor B cost $5,000 and funded 1 loan, their CPFL is $5,000 — twice as expensive despite lower CPL.
Benchmark: for refinance leads, a CPFL under $3,000 is solid. Top-performing teams with strong speed-to-contact and follow-up processes achieve $1,500-$2,000.
3. Return on Ad Spend (ROAS)
Revenue generated ÷ total lead spend. If $10,000 in leads generated $16,000 in origination fees, your ROAS is 1.6x. Anything above 1.0x means you’re profitable on the lead spend alone (before accounting for overhead). A 2x-3x ROAS is a strong lead channel worth scaling.
4. Lifetime Value (LTV) Per Source
Beyond the initial funded loan, consider: does this borrower refinance again? Do they refer others? Do they come back for a purchase loan? Leads from organic search and content tend to have higher LTV because the borrower found you through trust-building content. Purchased leads with no brand connection may fund once but are less likely to return.
Building Your Tracking System
Step 1: Tag every lead at the source. Your CRM should capture which vendor, campaign, and lead type generated each lead. If your CRM can’t track lead source through to funding, that’s the first problem to solve. Most modern mortgage CRMs (Velocify, Encompass, Shape, Jungo) support source tracking.
Step 2: Define your funnel stages. Lead received → contacted → application submitted → in processing → clear to close → funded. Track conversion rates between each stage, by source.
Step 3: Run the math monthly. Pull a monthly report per lead source showing total leads, contact rate, application rate, funded count, total spend, CPL, and CPFL. This takes 30 minutes per month and gives you the data to make smart allocation decisions.
Step 4: Give it time. A refinance lead can take 30-60 days from submission to funded loan. Don’t evaluate a lead source on 2 weeks of data — you need at least 60-90 days to see the full pipeline play out. First-month data tells you about contact rates. Third-month data tells you about funded loans.
When to Scale, Hold, or Cut a Lead Source
Scale (increase budget): CPFL under $2,500 AND consistent month-over-month. The source is profitable and predictable. Increase volume incrementally (20-30% per month) and verify that quality holds as volume grows.
Hold (maintain current spend): CPFL between $2,500-$3,500. Profitable but not exceptional. Look for optimization opportunities — can you negotiate better pricing, improve speed-to-contact, or tighten geographic filters?
Cut (reduce or eliminate): CPFL above $4,000 after 90 days of data. The economics don’t work. Before cutting, confirm that the issue is lead quality (not your team’s follow-up). If contact rates are strong but applications and funded loans are weak, the leads are low quality. If contact rates are the problem, the issue might be your speed-to-contact, not the vendor.
For teams looking to build or optimize their refinance lead pipeline, schedule a strategy call to discuss your current metrics and where the opportunities are.
Frequently Asked Questions
How long should I test a new lead source before deciding?
Minimum 60-90 days with at least 50-100 leads. Refinance loans take 30-60 days to close, so you need enough time for the pipeline to mature. Judging a source on 2 weeks of contact-rate data misses the conversion picture entirely.
What’s a good ROAS for mortgage lead buying?
2x-3x ROAS is strong for purchased leads. That means for every $1 spent on leads, you’re generating $2-$3 in origination revenue. Above 3x is exceptional and signals a source worth aggressive scaling.
Should I track organic leads the same way?
Yes. Organic leads from your website, blog, or SEO have a cost too — the time and money spent creating content and optimizing pages. Track them through the same funnel to compare true performance across all channels. Organic leads typically show lower CPL and higher LTV than purchased leads.
