Cost per lead is easy to calculate—and easy to misinterpret. Cost per funded deal connects acquisition spend to the outcome that pays the company.
A $75 lead is not cheaper than a $150 lead if the first source requires twice the sales labor and produces one-third as many funded transactions. Business funding buyers need cohort economics, not a headline price.
The basic formula
Lead-only cost per funded deal = net lead spend ÷ funded deals
The more useful version includes operating costs required to convert the cohort:
Fully loaded cost per funded deal = total attributable acquisition cost ÷ funded deals
Total attributable acquisition cost can include net vendor spend, follow-up labor, allocated data and software, and other variable acquisition costs. Use one defined cohort: the same vendor, product, source, delivery period, and acceptance rules.
Define the funnel before calculating cost
- Delivered: records received from the source.
- Accepted: records meeting contracted acceptance criteria.
- Contacted: prospects with whom meaningful contact occurred.
- Qualified: prospects meeting internal sales criteria.
- Application completed: required application submitted.
- Approved: application approved for the relevant product.
- Funded: funds actually disbursed.
Do not combine approved and funded deals. Approval is a useful leading indicator, but it is not the same economic outcome.
Diagnostic rates
- Acceptance rate = accepted leads ÷ delivered leads
- Contact rate = contacted leads ÷ accepted leads
- Qualification rate = qualified leads ÷ contacted leads
- Application rate = completed applications ÷ qualified leads
- Approval rate = approved applications ÷ completed applications
- Funding rate = funded deals ÷ accepted leads
Always label the denominator. A “7% funding rate” is ambiguous unless the reader knows whether it means 7% of delivered, accepted, contacted, or completed applications.
Which costs should be included?
Net vendor spend
Use the actual invoice for the cohort minus attributable refunds or credits. If invalid records are replaced rather than refunded, document how replacements are counted.
Follow-up labor
Include labor that changes with lead volume: attributable hours multiplied by a consistently calculated fully loaded hourly cost.
Data and software
Include costs specifically used to process or contact the cohort, such as allocated CRM, enrichment, dialer usage, messaging, or call tracking. Avoid assigning an arbitrary share of every company subscription.
Other variable acquisition costs
Depending on the model, these may include incremental commissions, outsourced qualification, or per-application processing. Do not count funding principal as acquisition expense; it is capital deployed.
A worked example
The following numbers are entirely illustrative and are not suggested benchmarks.
| Item | Illustrative result |
|---|---|
| Leads delivered / accepted | 100 / 96 |
| Funded deals | 7 |
| Gross vendor invoice | $15,000 |
| Credits | $600 |
| Follow-up labor | $1,680 |
| Data/software + other variable cost | $720 |
Net vendor spend is $14,400. Fully loaded acquisition cost is $16,800. Lead-only cost per funded deal is $2,057.14, while fully loaded cost per funded deal is $2,400. The advertised $150 lead price does not tell that complete story.
Connect cost to contribution
Compare cost per funded deal with pre-acquisition contribution—not funding principal or gross funding volume.
Pre-acquisition contribution per funded deal = buyer revenue − transaction-level fulfillment and servicing costs.
Post-acquisition contribution = total pre-acquisition contribution − total attributable acquisition cost.
Each buyer must use actual revenue, commissions, losses, servicing costs, timing, and capital economics.
Account for conversion lag
Do not compare a cohort delivered last week with one delivered three months ago if transactions take time to close. Wait for a predetermined maturity date or label the result interim and incomplete. Record both lead-delivery and funding dates.
Segment without fooling yourself
Review results by vendor, product, state, requested amount, time in business, industry, lead age at first contact, sales team, and delivery window when sample size permits. Always show lead and funded-deal counts next to the rate; tiny segments are unstable.

Frequently asked questions
What is a good cost per funded deal?
There is no universal answer. It must fit below the risk-adjusted contribution your company can earn while meeting margin and capacity requirements.
What if there are zero funded deals?
Cost per funded deal is not yet available—not zero. Report spend, cohort age, and pipeline stages.
Can approvals substitute for funded deals?
No. Cost per approval is a useful interim metric, but it should remain separate.
