Sizing your dialer spend against revenue per agent

Sizing your dialer spend against revenue per agent is the only cost test that matters: if each agent earns far more than they cost to keep dialing, the dialer line is rounding error. The trick is to put both numbers on the same page.

For the cost side of that page, our pillar on what VICIdial really costs lays out the server, carrier, and labor model. Here we set it beside what agents bring in.

Define revenue per agent first

Revenue per agent is the gross revenue an agent produces in a period divided by the number of agents. Drive it from your Close rate, the share of contacted leads that convert, and your Conversion rate, the share of dials that turn into a sale or qualified outcome. If ten agents close enough deals to cover their own wages and a margin on top, you already know the business works. The question is how much the tooling underneath them eats into that margin.

Put cost per agent next to it

Your dialer cost per agent is total monthly dialer spend divided by seat count. Because VICIdial has no per-seat license, that figure is mostly the server, your carrier minutes, and either labor or a Managed hosting fee spread across the team. The more agents you put on one box, the smaller the fixed-cost slice each one carries. We dig into that arithmetic in VICIdial cost per agent.

The ratio that tells the story

Divide Revenue per agent by cost-per-agent and you get a ratio. For most outbound shops that ratio is large, because the dialer is a small flat cost and the revenue is the whole point of the operation. When the ratio is healthy, do not waste a week shaving dollars off the server line. Spend that week raising Contact rate, the share of dials that reach a person, because more contacts feed more closes feed more revenue per agent.

Where the dial mode comes in

How you dial changes both halves of the ratio. Predictive dialing places multiple calls ahead of available agents to keep them on the phone, which raises Occupancy, the share of paid time spent in productive call work. Higher occupancy lifts revenue per agent. But push the Dial level, the multiplier of calls per agent, too high and your Drop rate, the share of answered calls with no agent ready, climbs and burns minutes for nothing. The dial mode you choose is a revenue lever, not just a cost lever.

When the ratio is tight

If your ratio is uncomfortably close to one, look at the cost side last. First check whether agents are sitting idle, whether your lead quality is weak, and whether dropped calls are eating carrier minutes. Only after those are clean does trimming infrastructure matter, and even then the savings are small relative to wages. The agents are the expensive resource; the dialer just keeps them busy.

Keeping the cost side predictable

A predictable cost denominator makes this ratio easy to track month to month. We charge a flat fee per server with no per-agent licensing and no markup on your carrier minutes, so the cost line does not jump when you add seats. You bring your own Carrier and your own DID (direct inward dialing) numbers, the phone numbers your agents dial from. For current numbers to plug into your ratio, see our pricing page.

Run the ratio once a month. If it stays wide, your dialer spend is doing its job.
