Lead to Close Rate Calculator

Background.

A quarter's numbers land on a sales director's desk: 1,200 new leads, 42 new customers. The lead-to-close rate is 42 ÷ 1,200 = 3.5%, and by itself it cannot say what to fix. Marketing might be sending people who were never going to buy, qualified leads might be stalling before anyone opens a deal, or reps might be losing the deals they do open. All three produce the same 3.5%.

So the calculation runs through the stages in between. With 420 of those leads qualified and 168 turned into opportunities, the funnel converts 35% at the first gate, 40% at the second and 25% at the last — and 0.35 × 0.40 × 0.25 is exactly 0.035. Because the overall rate is a product, raising any one stage by a fifth raises the whole by a fifth, wherever that stage sits. Lifting the closing stage from 25% to 30% and lifting qualification from 35% to 42% each take the overall rate to 4.2%. Which one to chase becomes a question of cost, not arithmetic.

Every figure here is a cohort rate: of the leads that arrived in the period, how many have reached each later stage so far. That is a different statistic from the win rate a CRM displays, which in Salesforce's documented report is won ÷ closed and ignores deals still open. Measure a period at least one full sales cycle old, or the later stages will look worse than they are.

Two planning numbers come out of the same inputs. Leads per closed deal, 28.5714 here, tells you how much demand a sales target needs. Revenue per lead, $332.50 at a $9,500 average first-year deal, is the most a lead can be worth before the costs of selling and serving the customer.

What is lead to close rate calculator?

Lead-to-close rate is the percentage of leads entering a sales pipeline that end as won customers. It decomposes into stage rates — lead to qualified, qualified to opportunity, opportunity to closed-won — that multiply to the end-to-end figure. The stage names follow HubSpot's published lifecycle ladder: a Lead has converted or interacted beyond a subscription sign-up, a Marketing Qualified Lead is one marketing has judged ready for sales, a Sales Qualified Lead is one sales has accepted as a potential customer, an Opportunity is associated with a deal, and a Customer has at least one closed deal. Other CRMs use other labels; what matters is mapping them once and never moving the lines.

How to use this calculator.

1. 01Pick a period and treat it as a cohort: every count you enter should describe the leads created in that window, followed to wherever they have got to by now.
2. 02Enter all leads created, including prospects your reps found themselves. If self-sourced deals appear in the wins but not in the leads, the close rate is inflated.
3. 03Enter qualified leads at the gate your team really uses — MQL, SQL or an equivalent — then opportunities created and deals closed won from the same cohort. At least one win is needed.
4. 04Add an average first-year deal value to see revenue per lead, or leave it at 0 if you only want the rates. Keep multi-year contract values out of the average.
5. 05Read the line naming the weakest stage, then check it for data problems before acting: unworked leads and stale open deals both look like poor conversion.

The formula.

With L leads, Q qualified, O opportunities and W wins, the three stage rates are Q ÷ L, O ÷ Q and W ÷ O, each shown as a percentage. The lead-to-close rate is W ÷ L × 100. Multiply the three stage fractions and the middle counts cancel, (Q ÷ L) × (O ÷ Q) × (W ÷ O) = W ÷ L, which is why the product of the stages always reproduces the overall rate.

Leads per closed deal is L ÷ W, the reciprocal of the close rate expressed as a fraction: 100 ÷ 3.5 and 1,200 ÷ 42 both give 28.5714. Revenue per lead is W × deal value ÷ L, the same as deal value multiplied by the close rate.

The weakest stage is simply the lowest of the three stage percentages, quoted to two decimals; if two or all three are equal it says so rather than picking one. The counts must narrow down the funnel — W ≤ O ≤ Q ≤ L — and a set that widens anywhere is rejected, since a stage cannot convert more people than reached it. When reps open opportunities without a formal qualification step, count those leads as qualified so the chain stays intact.

Gives the formula WON:SUM / CLOSED:SUM and states that it "calculates the win rate based only on opportunities that have been closed (either won or lost)" — the basis for this page's warning that its cohort opportunity-to-win rate is not the same statistic as a CRM win rate.
