Example Data Table
| Scenario | Total Leads | Qualified Leads | Closed-Won | Months | Closed-Won Per Month |
|---|---|---|---|---|---|
| Starter funnel | 600 | 210 | 36 | 3 | 12.00 |

Formula Used
Closed-won leads per month = Closed-won leads ÷ Period months
Lead-to-won rate = Closed-won leads ÷ Total leads × 100
Qualified-to-won rate = Closed-won leads ÷ Qualified leads × 100
Monthly revenue = Closed-won leads per month × Average deal value
Target attainment = Closed-won leads per month ÷ Monthly target × 100
Sales velocity per day = Monthly qualified leads × Qualified-to-won rate × Deal value ÷ Sales cycle days
Next month forecast = Monthly leads × (1 + Growth rate) × Forecast close rate
How to Use This Calculator
Enter your total leads for the selected period. Add the qualified leads and closed-won leads from the same period. Enter the number of months covered by the data. Add your monthly target and average deal value. Use sales cycle days to estimate velocity. Add growth and forecast close rate for next month planning. Leave forecast close rate empty when you want the calculator to use your actual close rate. Press calculate. The results appear above the form. Use CSV or PDF buttons to save the report.
Why monthly closed-won tracking matters
Closed-won leads show how many real opportunities became paying customers during a chosen period. A monthly view makes this number easier to compare. It removes noise from long campaigns, seasonal spikes, and delayed follow-ups. Sales managers can see whether the team is improving or slipping. Founders can also connect demand, staffing, and cash flow.
The metric is simple, but the context matters. A team may close ten leads in one month. That result is stronger when lead volume is low. It is weaker when hundreds of qualified leads were available. This calculator compares closed-won count with total leads, qualified leads, targets, deal value, team size, and cycle time.
What the results reveal
The main output is closed-won leads per month. The calculator also estimates lead-to-won rate, qualified-to-won rate, monthly revenue, target gap, attainment, wins per rep, and wins per working day. These views help diagnose the funnel. Low lead-to-won rate can signal weak fit. Low qualified-to-won rate can show pricing, timing, or proposal problems.
Sales velocity adds another layer. It estimates how much value the pipeline can produce each day. A shorter sales cycle improves velocity. Better qualification also improves it, because the team spends time on leads more likely to buy.
Forecasting future wins
Forecasting is included for planning. You can add a monthly lead growth rate and a forecast close rate. The calculator then projects next month closed-won leads and revenue. This is not a guarantee. It is a planning estimate. Use it with recent data and realistic assumptions.
How to improve the number
To raise closed-won leads per month, improve the quality of lead sources first. Then shorten response times. Keep notes on reasons for lost deals. Review calls, proposals, and pricing objections. A small gain in close rate can have a large monthly impact.
Use the same measurement window each time. Compare month with month, not scattered date ranges. Update targets when team size or market conditions change. Over time, this creates a cleaner picture of growth and sales execution.
Share the report with marketing and finance teams. Marketing can adjust channel spending. Finance can model cash timing. Leaders can set coaching priorities with evidence. Everyone sees the same monthly truth.
FAQs
What are closed-won leads?
Closed-won leads are leads that became paying customers or signed deals. They represent successful sales outcomes, not just interested prospects or open opportunities.
How do I calculate closed-won leads per month?
Divide total closed-won leads by the number of months in your reporting period. For example, 60 closed-won leads over 5 months equals 12 per month.
Should I use total leads or qualified leads?
Use both when possible. Total leads show overall funnel quality. Qualified leads show how well sales converts serious opportunities into customers.
What is a good closed-won rate?
A good rate depends on industry, offer, pricing, and lead source. Compare your rate against your past months first. Internal trend data is often more useful.
Why is sales cycle length included?
Sales cycle length helps estimate sales velocity. A shorter cycle can create faster revenue even when monthly win count stays the same.
Can this calculator forecast next month?
Yes. Enter lead growth and forecast close rate. The calculator estimates next month wins and revenue using your current monthly lead volume.
What if my monthly target is zero?
The calculator still shows closed-won results. Target attainment will show as zero because a target is needed for a meaningful percentage comparison.
Can I export the result?
Yes. After calculation, use the CSV or PDF buttons above the form. The exports include key performance metrics from your entered data.
