How results are calculated

We estimate annual lost revenue using your stores, average SKUs, units/day and current OOS + distribution. We combine OOS and distribution using a non-overlap method and apply the Navimate recovery % to show likely recovered revenue.

How accurate is the calculation?

The model uses your inputs (units/day, OOS %, distribution gaps, margin) to calculate lost revenue using industry-standard formulas.

How does Navimate reduce OOS?

Through photo verification, real-time issue alerts, improved visit frequency, and better task compliance — reducing OOS events by 30–40%.

Is this calculator for CPG, FMCG, and retail teams?

Yes. It’s built specifically for trade marketing, field sales, and merchandising organizations.

Does it include distribution gaps?

Yes. The calculator adds distribution void losses to OOS losses for a complete view.
