Lead-to-Close Rate Calculator
72 of 480 leads closed, a 15.0% close rate.
What is Lead-to-close rate?
Lead-to-close rate is the share of leads that become paying customers, calculated as closed deals divided by leads, times 100. Close 72 of 480 leads and the rate is 15.0%.
It is a bottom-of-funnel measure of sales efficiency: of the interest you generated, how much turned into revenue. The flip side is leads per close, which here is about 7, meaning roughly 7 leads for every deal won.
The figure only means something next to your lead definition. A rate built on raw inbound leads is not comparable to one built on sales-qualified leads, so always note which you are counting.
How to calculate Lead-to-close rate
Lead-to-close = Closed ÷ Leads × 100
- Count the leads. Count leads generated in the period, and be clear about the stage: all inbound, marketing-qualified, or sales-qualified.
- Count the closed deals. Count the leads from that same set that became paying customers.
- Divide and multiply by 100. Closed deals divided by leads, times 100, is the rate. 72 divided by 480 is 0.15, or 15.0%.
- Read it as leads per close. Invert it for a planning figure: a 15.0% rate is about 7 leads per close, so you know how many leads a revenue target needs.
Worked example
A sales team works 480 leads over a quarter and closes 72 of them into paying customers.
| Leads | 480 |
|---|---|
| Closed deals | 72 |
| Result | 15.0% lead-to-close rate |
About 1 in every 7 leads became a customer. Whether 15% is good depends on how qualified those 480 leads were: strong for broad inbound, less so if sales had already filtered them.
How to improve Lead-to-close rate
- Tighten lead qualification so sales spends time on leads that can actually close, which lifts the rate at the source.
- Speed up follow-up: contacting a fresh lead quickly closes far more than a delayed first touch.
- Fix the handoff between marketing and sales so context and intent are not lost when a lead is passed over.
- Track the rate by lead source, since the channels that convert best are rarely the ones that deliver the most volume.
Frequently asked questions
- What is lead-to-close rate and how do you calculate it?
- Lead-to-close rate is the share of leads that become paying customers, calculated as closed deals divided by leads, times 100. Close 72 deals from 480 leads and the rate is 15.0%. It measures how efficiently the sales process turns interest into revenue.
- What is a good lead-to-close rate?
- There is no universal number, because it depends almost entirely on what you count as a lead. A rate built on raw, unscored leads will look low, while one built on sales-qualified leads will look far higher for the same business. What drives it is lead quality, sales follow-up speed, deal complexity and price. The honest benchmark is your own rate over time and how it moves when you change one of those things.
- Is a 15% lead-to-close rate good?
- It can be strong or weak depending on the lead definition behind it. 15% off broad, top-of-funnel leads would be a healthy result, while 15% off tightly qualified leads that sales hand-picked might signal a follow-up or fit problem. Always read the rate next to the stage at which you count a lead.
- What is the difference between conversion rate and lead-to-close rate?
- Conversion rate usually measures an early action like a signup or form fill against visitors, while lead-to-close measures the final step: leads that turn into paying customers. They sit at opposite ends of the funnel. A site can have a high conversion rate to leads and still close few of them, which is exactly the gap this metric exposes.
- Why does lead quality matter more than the raw rate?
- Because a higher rate is not always better. Tightening your lead definition raises the close rate but can shrink total revenue if you turn away winnable deals; loosening it lowers the rate but may add closed business. Read lead-to-close alongside the number of deals closed, not on its own, so you optimize for revenue rather than a flattering percentage.
