There's a number that doesn't appear in most sales capacity models: the hours your SDRs spend on research before they can make a call worth making. It's not tracked in your CRM. It doesn't show up in your activity reports. But for most outbound-led teams, it represents somewhere between 20% and 30% of each rep's working week — and it scales directly with headcount.
The calculation is straightforward. A rep researching 40 leads per month, spending an average of 60 minutes per company on LinkedIn, Google, and your CRM, is spending 40 hours a month on research alone. At a UK mid-market SDR salary of around £35,000–£40,000, that's roughly £700–£800 of direct employment cost per month being consumed before a single call is made. For a team of 8, that's north of £80,000 a year — and it compounds as you scale.
The more interesting question isn't the cost. It's what's not happening because of it. When a rep runs out of prep time, calls don't get made. When calls don't get made, pipeline doesn't get built. The research tax isn't just a cost item — it's a pipeline constraint. The full article will walk through how to calculate this precisely for your team size, what good looks like for different outbound motions, and the infrastructure decisions that determine whether this problem gets solved or just managed.
