## Why blended sales cycles mislead
A blended average hides the reality that small deals close quickly while large deals take months.
## Calculate median and 75th percentile days
For each deal size band, find the median and 75th percentile days from opportunity created to contract signed.
## Band minimums for accuracy
Each deal size band needs at least 15 closed deals to be meaningful for forecasting.
## The blended average problem
The blended average across all deals is 45 days but the dollar-weighted cycle is 76 days for revenue impact.
## Top band cycle length
The top band takes 121 days to close while the bottom band takes 24 days.
## Cash timing vs cycle length
Cash timing is separate from cycle length and includes payment terms after contract signing.
## Runway check before chasing bands
Runway in months minus band's median cycle minus payment terms must be positive to avoid cash shortages.
## Pipeline coverage issue
Top-band pipeline created in last 30 days of a quarter can't close within the same quarter's coverage.
## Rebuild forecast by segments
Multiply opportunities opened by win rate and ACV, then shift results by median cycle for accurate forecasting.
## Shorten enterprise cycles
Identify the stage holding the wait and fix it for faster enterprise deals.
## Security review fix
Send answers before security review requests to reduce wait time for enterprise deals.
## Legal process improvement
Send contracts with proposals rather than after verbal agreement to speed up legal review.
## Procurement process fix
Ask in first meeting who signs and walk through buying process step by step.
## Mutual action plan
Create a shared document listing steps, owners, and dates to track progress.
## Band-specific forecasting
Forecast each band separately using median cycle to avoid cash shortages.
## Hiring impact of cycle length
A 76-day dollar-weighted cycle means two and a half months of unplanned salary for new reps.
## Key takeaway

Calculating sales cycle length by deal size using median and 75th percentile days improves cash planning and hiring decisions.
