Contact Volume Forecast Calculator
Enter recent contact volumes with weights, then apply growth, seasonal, event, and variance assumptions.
A QUICK WALKTHROUGH
How to use this tool
- Enter up to 24 recent period volumes and matching weights.
- Set the growth rate and seasonal, event, and scenario variance factors.
- Review the baseline, adjusted expected volume, and low/high scenario range.
Weighted recent volume
Baseline = sum(period volume × weight) ÷ sum(weights). Up to 24 finite, non-negative period values and positive weights are accepted.
Scenario arithmetic
Adjusted expected = baseline × (1 + growth rate) × seasonal factor × event factor. Low and high apply your variance percentage to that adjusted value.
Use assumptions carefully
Seasonal and event multipliers can double count the same effect. This forecast is scenario arithmetic only, not a statistical model or confidence interval.
GOOD TO KNOW
Common questions
How many periods can I enter?
Enter one to 24 comma-separated period volumes, with the same number of comma-separated weights.
Can factors double count?
Yes. Review whether your seasonal and event multipliers describe separate effects before using the result.
Does this produce confidence intervals?
No. Low and high are user-scenario bounds from your variance percentage, not confidence intervals.
