Before investing in a new lead source, campaign, or outbound hire, it helps to know roughly what kind of return you’re aiming for. Our free Sales ROI & Pipeline Calculator turns three simple inputs into a clear revenue projection.

How it works: enter your monthly lead volume, your expected conversion rate (the percentage of leads that become paying customers), and your average deal size. The calculator instantly projects the number of deals closed per month, monthly revenue, and annualized revenue based on those inputs.

Who this is for: sales leaders building a pipeline forecast, founders evaluating whether a new lead source or database subscription is worth the cost, and marketing teams justifying budget for a new campaign by showing the expected revenue outcome.

How to use the numbers: this calculator is meant for quick, directional planning — useful for answering questions like “”if we get 200 leads a month at a 5% close rate, is this campaign worth running?”” rather than for precise financial forecasting, which should account for factors like sales cycle length, seasonality, and lead quality variance.

A note on conversion rates: a healthy B2B conversion rate from lead to closed deal varies widely by industry and lead source — typically somewhere between 1% and 10% for cold-sourced leads, and often higher for inbound or referral leads. If you’re unsure of your own rate, look at your last 3–6 months of closed-won data as a starting benchmark.

Adjust the numbers above to model a few different scenarios — a conservative case and an optimistic case — before setting a target for your next campaign.
