Call Centers & BPO
How much does a bad-quality lead list cost your call center?
Every dead number on a list isn't free — it's agent time that gets paid the same, but produces zero conversations. The calculator below estimates that monthly cost with your own numbers; the example that follows shows how the math works.

How the cost of a bad-quality list is calculated
The formula is simple: number of agents × calls per day × % invalid numbers × agent cost per hour ÷ calls per hour gives you the daily cost of dialing numbers that never should have been there. Multiplied by the month's business days, that's the real monthly cost.
[On the website, this section includes an interactive calculator: number of agents × calls per agent per day × % invalid numbers × agent cost per hour ÷ calls per hour = daily cost of wasted time, multiplied by 21 business days for the monthly estimate. Example with 10 agents, 60 calls/day, 30% invalid, $4/hour, 12 calls/hour: ≈ $1,260 USD/month in wasted time.]
What do you do with this number?
It isn't meant to generate guilt — it's meant to give you a concrete figure to compare against the premium of switching to a verified list. If the monthly cost of bad quality is higher than the premium for verified, exclusive data, the switch pays for itself.

Frequently asked questions
Does this calculator use Qurada data or is it generic?
It's a generic opportunity-cost formula — apply it with your operation's real numbers, not ours.
How much does this cost drop with a verified list?
It depends on your current list's invalid-number rate — the higher it is, the greater the potential savings from switching to one-by-one verified data.
