Cold Email ROI Calculator

Cold email economics live or die on the funnel: volume times reply rate times meeting rate times close rate. Small changes compound, so it pays to model it before you scale spend.

Revenue versus cost. Use conservative rates.

How it works

The calculator walks volume through each conversion step to estimate meetings, closed deals, and revenue, then compares revenue to your monthly cost for an ROI multiple. Use conservative rates; inflated assumptions produce a number that feels good and predicts nothing.

Make these numbers real.

Scheduler Zero handles warmup, authentication, and reputation so your deliverability stays high and your funnel math actually holds up.
