The sales conversion rate tracks how efficiently prospects flow through key deal stages, from marketing qualification to sales qualification, and finally to closed sales. Evaluating conversion rates at individual stages helps business leaders isolate bottlenecks. For example, if Lead-to-MQL conversion is high but SQL-to-Close is low, it suggests that the marketing team is generating volume that does not meet sales criteria or the sales team is failing to close qualified prospects. ## Sales Funnel Stage Formulas Funnel efficiency is calculated using stage-to-stage percentage conversion rates: 1. **Lead to MQL Conversion (\%):** $$\text{Lead-to-MQL} = \left( \frac{\text{Marketing Qualified Leads (MQL)}}{\text{Total Leads}} \right) \times 100$$ 2. **MQL to SQL Conversion (\%):** $$\text{MQL-to-SQL} = \left( \frac{\text{Sales Qualified Leads (SQL)}}{\text{Marketing Qualified Leads (MQL)}} \right) \times 100$$ 3. **SQL to Closed Won Conversion (\%):** $$\text{SQL-to-Closed} = \left( \frac{\text{Closed Won Deals}}{\text{Sales Qualified Leads (SQL)}} \right) \times 100$$ 4. **Overall Sales Conversion Rate (\%):** $$\text{Overall Conversion} = \left( \frac{\text{Closed Won Deals}}{\text{Total Leads}} \right) \times 100$$ ## How to Use This Calculator Enter your total leads for the period, then how many became Marketing Qualified Leads (MQL), how many of those were accepted as Sales Qualified Leads (SQL), and how many SQLs closed as paying customers (Closed Won). The calculator divides each stage by the one before it to show where prospects drop off — Lead-to-MQL, MQL-to-SQL, and SQL-to-Closed — plus one overall Closed Won ÷ Total Leads rate so you can compare funnel health period over period. ## Worked Example: B2B SaaS Quarter A B2B team generates 5,000 leads in a quarter. 1,500 become MQLs, 600 of those are accepted as SQLs, and 120 close as paying customers. Lead-to-MQL = (1,500 / 5,000) × 100 = 30%. MQL-to-SQL = (600 / 1,500) × 100 = 40%. SQL-to-Closed = (120 / 600) × 100 = 20%. Overall conversion = (120 / 5,000) × 100 = 2.4%, which sits within the typical 1%-3% B2B benchmark. ## Related Calculators Trace conversions further with the [lead-to-customer calculator](/calculators/lead-to-customer-calculator), size the leads you need to hit a revenue goal with the [leads needed calculator](/calculators/leads-needed-calculator), or check what each closed deal costs with the [marketing CPA calculator](/calculators/marketing-cpa-calculator). ## Frequently asked questions ### What is a sales conversion rate? The percentage of prospective leads that complete a purchase or sign up to become paying customers. ### What is a good sales conversion rate? For B2B software, a good overall lead-to-close conversion rate is 1% to 3%. For e-commerce store checkouts, target 2% to 4%. ### How is a Lead converted to an MQL? Leads qualify as MQLs when they interact with key content, download resources, or meet defined buyer profile criteria. ### What is the difference between MQL and SQL? MQLs are qualified by marketing interactions. SQLs are vetted by sales reps as having direct buying intent and budget. ### How can I improve my SQL-to-Close rate? Improve it by training sales reps, providing clear case studies, streamlining pricing proposals, and addressing objections quickly. ### What is funnel leakage? Funnel leakage occurs when prospects drop out of the sales pipeline between stages, indicating friction or poor qualification. ### Does email automation improve conversion rates? Yes, automated nurture sequences keep leads engaged, helping them qualify and progress through the funnel. ### How does lead source affect conversion rates? Organic search and inbound referral leads convert at significantly higher rates than outbound cold outreach lists. ### What is the conversion rate of a landing page? The percentage of page visitors who complete the form/action to become a lead. ### How do I handle low MQL-to-SQL rates? Align marketing and sales teams on qualified criteria to ensure marketing targets the correct customer profile. ## Related guides - [Paid Media Metrics Guide: CPC, CPM, CTR, CPA, ROAS, and ROI in Plain English](https://dothecalculation.com/blog/marketing/paid-media-metrics-guide) — Understand the paid media metrics that actually matter.
