How this calculator works

This tool estimates the 12-month return created by the customers you win from one month of lead gen spend. It does not assume you repeat the same performance every month for a year.

If you want an annual run-rate view, rerun the numbers using your expected monthly averages and multiply the outcomes yourself.

Big levers: cost per meeting, close rate, deal size, and margin. Small improvements compound quickly.

Sanity checks

If your output feels unrealistic, check these inputs first:

  • Cost per booked meeting: is it fully loaded (media, tools, labour)?
  • Close rate: are you measuring from first meeting to signed?
  • Deal size: is it first-12-months value, not just first invoice?
  • Margin: is it gross margin (delivery costs only), not net margin?

Want to improve these numbers?

Reduce cost per meeting, increase close rate, or increase deal value, you don’t just improve ROI, you make your pipeline more predictable.

We’ll show you where your pipeline leaks and what to change first to lift ROI without increasing spend.
