Cold Email ROI Calculator
Estimate replies, meetings, customers, revenue and return on investment before you launch. Adjust every assumption and use your own numbers.
Campaign assumptions
Percentages should reflect your own recent campaigns where possible.
ROI = (estimated revenue − campaign cost) ÷ campaign cost × 100.
Estimated result
A planning estimate—not a performance promise.
How to use this calculator
- Enter the number of relevant, permissioned prospects—not the size of a raw database.
- Use positive replies, excluding unsubscribe requests and automatic responses.
- Set meeting and close rates from your own funnel, or start conservatively.
- Include data, software and labour in campaign cost.
- Run a downside case before approving spend.
What the model leaves out
Timing, sales-cycle length, repeat purchases, gross margin, refunds and team capacity all affect real return. Treat the output as a transparent planning model. It does not make sending an email lawful or appropriate.
Responsible outreach: follow the rules that apply to your sender, recipient and location. Use a clear identity, relevant message and functional opt-out. In Australia, review current ACMA Spam Act guidance before sending commercial electronic messages.
