Enter your sending volume and funnel rates to estimate how many replies, meetings, deals, and dollars your cold email program can produce in a month.

A cold email ROI calculator estimates the revenue an outbound program produces by running your send volume through the funnel: emails sent → delivered → replies → positive replies → meetings → closed deals → revenue. Multiply emails per day by sending days for monthly volume, then apply your deliverability, reply rate, positive-reply share, meeting rate, and close rate, and finally your average deal value. For example, 200 emails/day over 22 days at 95% delivery, a 3% reply rate, 25% positive, 60% to a meeting, and a 20% close at $2,000 per deal projects roughly 4 closed deals and about $7,500 in monthly revenue. Adjust each rate to match your own numbers — the tool below recalculates instantly.
Each stage multiplies the one before it. Monthly sends = emails/day × sending days. Delivered = sends × deliverability. Replies = delivered × reply rate. Positive = replies × positive share. Meetings = positive × meeting rate. Deals = meetings × close rate. Revenue = deals × average deal value. Because the stages compound, deliverability and reply rate matter more than they look — a small lift early multiplies all the way down to revenue.
Cold email benchmarks vary widely by list quality, offer, and niche, so use your own data where you have it. As rough starting points many B2B senders see reply rates in the low single digits, with a minority of replies being positive. The single biggest lever is usually deliverability: emails that land in spam never get the chance to reply. That's why dedicated sending domains, warmup, and list hygiene matter before you optimize copy.
This is a planning estimate. Real results depend on your offer, targeting, copy, timing, and follow-up. Treat the output as a model for 'what would it take to hit my number' — for instance, work backwards from a revenue goal to the send volume and reply rate you'd need, then decide whether that's achievable with your current setup.
Run your send volume through the funnel and apply your conversion rates at each stage: emails sent → delivered (× deliverability) → replies (× reply rate) → positive replies (× positive share) → meetings (× meeting rate) → deals (× close rate) → revenue (× average deal value). ROI is the resulting revenue measured against the cost of your tools and time. The calculator on this page does the math for you as you adjust each input.
It varies a lot by list quality, offer, and industry, but many B2B cold email programs see reply rates in the low single digits, with only a portion of those replies being positive. Rather than chase a benchmark, plug your own historical reply rate into the calculator; if you don't have one yet, model a conservative figure and a stretch figure to bracket the outcome.
Because the funnel compounds. If emails land in spam, they can't be opened or replied to, so a drop in deliverability scales down every later stage — replies, meetings, deals, and revenue all fall proportionally. That's why senders invest in dedicated domains, warmup, and clean lists before optimizing subject lines: protecting the inbox rate protects the entire funnel.
