Load the Baseline you are measuring against: the plan, or a forecast you saved. Every bridge in this report runs from it.
Month by month since launch. Month 1 is your launch month. Close each month once it is complete. A closed month locks, and any figure changed after it was saved is flagged. Enter units sold and net revenue. Net revenue per unit is worked out from them. The grey figure under each entry is the Baseline it is measured against.
Where the plan said you would be by now, against where you actually are.
Each line is one driver of the variance, in dollars. The lines add up to the total.
Is the miss steady from month to month, or concentrated in one month?
Where we land, how much of the gap comes back, and which months carry it.
The forecast against the baseline, month by month. Lock it to use it for what is left.
Set a lever to see what it is worth at year end, and what gap it leaves.
What changed since the last forecast, and how far this now sits from the original plan.
Which numbers exist, which one is on record, and how the view has moved since.
