Cost per lead (CPL) is the total amount spent on marketing or lead generation divided by the number of leads generated. It is one of the most fundamental metrics in lead generation, used by both firms generating their own leads and those buying leads from a provider.
How to Calculate Cost Per Lead
The formula is straightforward: divide your total spend by the number of leads received. If you spend £1,000 on a Facebook advertising campaign and generate 40 leads, your CPL is £25. If you buy 50 leads from a provider at £20 each, your CPL is £20.
However, the raw CPL figure only tells part of the story. A more useful calculation is the cost per qualified lead — your total spend divided by the number of leads that actually resulted in a meaningful conversation. If half your leads do not answer the phone, your effective cost per contacted lead is double your headline CPL.
Going further, the metric that matters most for your bottom line is cost per acquisition (CPA) — the total spend required to generate one completed client. If you buy 20 leads at £25 each (£500 total) and convert 2 into completed mortgage cases, your CPA is £250 per case. If your average revenue per case is £700, the return on investment is clear and positive.
What Affects CPL?
Several factors influence cost per lead in financial services:
Lead type — Different financial products have different CPLs. General mortgage leads might cost £10-£30, while specialist leads like equity release or commercial finance can cost £30-£70. The price reflects the difficulty and cost of reaching the right consumer audience.
Exclusivity — Exclusive leads cost more than shared leads because the generation company can only sell each lead once. However, the higher conversion rate from exclusive leads usually makes them more cost-effective on a per-acquisition basis.
Verification level — SMS-verified leads cost more than unverified leads because the verification process filters out a proportion of submissions. You pay more per lead, but you waste less money on dead numbers.
Geographic targeting — Leads in high-population areas like London and Manchester are typically cheaper because the audience pool is larger and advertising costs per impression are lower. Targeting specific rural areas or small towns costs more because the audience is smaller.
Competition — In highly competitive lead markets, the cost of advertising increases, which drives up CPL. Mortgage leads tend to be competitively priced because of high demand from brokers.
CPL Benchmarks for UK Financial Services
While every campaign and provider is different, here are broad CPL ranges for common UK financial services lead types. These figures assume exclusive, verified leads delivered in real-time:
Mortgage leads: £10-£45. Insurance leads: £10-£80. Equity release leads: £30-£70. Pension leads: £30-£60. Secured loan leads: £30-£60. Life insurance leads: £40-£80.
If a provider is quoting CPLs significantly below these ranges, it is worth asking about exclusivity, verification, and data freshness. Very cheap leads are often shared, unverified, or aged — all of which reduce conversion rates and can make the apparently cheap lead more expensive per acquisition.
CPL vs ROI: The Bigger Picture
Focusing too narrowly on CPL can lead to poor decisions. A £15 lead that converts at 5% costs you £300 per acquisition. A £35 lead that converts at 15% costs you £233 per acquisition. The cheaper lead is actually more expensive when measured against the metric that matters — cost per client.
This is why we encourage brokers and advisers to track the full pipeline: leads received, leads contacted, appointments booked, and cases completed. With this data, you can calculate your true cost per acquisition and make informed decisions about lead spend rather than optimising for the wrong metric.
