Formula
Copy the exact expression or work through it step by step below.
Forecast Revenue = Lead Volume x Conversion Rate x Average Deal Size Variables
FR
Forecast Revenue
The incoming amount used to size the sales forecast outcome.
LV
Lead Volume
The lead volume value plugged into the sales forecast calculation.
CR
Conversion Rate
The conversion rate assumption used in the sales forecast calculation.
ADS
Average Deal Size
The average deal size value plugged into the sales forecast calculation.
Step By Step
- 1
Set the baseline case with the real calculator inputs.
Starting Mrr = 80,000, Monthly Growth Percent = 5.00%, Pipeline Conversion Percent = 22.0%, Avg Deal Size = 1,200
- 2
Translate rates, periods, and cash values onto the same footing before combining them.
Keep the sales forecast assumptions consistent instead of mixing monthly and annual views.
- 3
Apply the formula and read the first calculator outputs, not just the headline assumption.
The calculator lands with projected mrr at horizon at $311,753 and cumulative forecast revenue at $2,332,421.
- 4
Run one changed scenario so the formula is stress-tested before it is trusted.
The sales forecast calculator page is the fastest way to compare that second case.
