Pay Per Call vs. Shared Leads: Running the Actual Numbers
A worked comparison of per-call and shared-lead buying, including the costs that never make it onto the spreadsheet.
The comparison between buying calls and buying shared leads usually gets made on unit price, which is the one dimension where it is least informative.
Here is the comparison done properly, with the costs that normally get left out.
The setup
Take a mid-sized insurance agency with twelve licensed agents. Assume the same media budget of $50,000 per month, spent two ways.
Shared leads at $22 each buys roughly 2,270 leads. Assume a 38% contact rate, and a 9% close rate on contacted leads. That is about 78 policies, or $641 in media per policy.
Per-call at $46 buys roughly 1,087 calls. Assume 74% billable — so the agency pays for 804 — and a 27% close on those. That is about 217 policies, or $230 in media per policy.
Those numbers are illustrative, but the shape holds across the agencies we work with.
Where the shared-lead model loses ground
The unit price is genuinely lower. The gap opens up in three places.
Contact rate. A shared lead sold to four buyers gets four calls in the first ten minutes. The first caller gets a conversation; the fourth gets voicemail. You are not buying a lead, you are buying a position in a queue, and the position is not disclosed.
Time decay. Shared-lead value halves within roughly the first hour and is largely gone by day two. That makes speed-to-contact the dominant variable, which in turn means you are really buying a staffing commitment, not a lead.
Agent time. This is the cost that never makes the spreadsheet. Working 2,270 leads at a 38% contact rate consumes far more agent hours than handling 804 inbound calls — and those hours are the constraint on most agencies, not media budget.
Price the agent hours at even a conservative loaded rate and the comparison stops being close.
Where per-call loses
It is not one-sided. Per-call is worse in three real situations.
Volume is lumpy and unpredictable. Calls arrive when consumers dial. If you need a steady, plannable flow to staff against, leads are easier to schedule around.
Your team cannot answer during buying hours. An unanswered call is pure loss, and there is no equivalent of "we'll get to it tomorrow."
You cannot define what disqualifies a caller. Per-call economics depend entirely on qualification rules. Without them, you pay premium prices for the same unqualified traffic.
The hybrid most agencies land on
In practice, most agencies that run both settle on a split: per-call inventory during staffed hours, shared leads to fill agent downtime, worked with the understanding that speed decides everything.
That is a reasonable equilibrium. It uses calls for the high-value hours where agent time is scarce, and leads for the hours where agent time would otherwise be idle.
The question underneath
The real question is not which channel is cheaper. It is which constraint is binding for you.
If media budget is the constraint, shared leads deserve a serious look. If agent capacity is the constraint — which it is for most agencies past a certain size — then anything that consumes agent hours without producing conversations is the expensive option, whatever the unit price says.
