"Floor Price" refers to the lowest acceptable price a sales person can go to. It can relate to different elements of the price waterfall, from the Pocket Price to adjusted pocket prices, to net invoice price or a multitude of other elements from the price waterfall. The floor price can visually be illustrated also with its counterpart, the maximum price, in a pricing corridor:

While the duality of a minimum floor price and a maximum price can be useful in certain international/channel scenarios, the most important is the Floor Price, as this helps secure minimum profitability.
So how do you establish what the right floor price should be? Different approaches include:
- The current, average pocket price plus some sort of nice-to-have increase in this budget year. This approach is typically used when Floor Prices are used to drive financial performance of the overall company.
- A target price based on estimates or actual research about the customer's willingness-to-pay.
- A specific price for one or more customers/channels to avoid commercial problems when those customers compare pocket prices, either between channels, countries or other comparison bases.
- Costs plus an acceptable target margin: typically called "cost plus pricing".
While the purpose of Floor Prices is to drive net prices higher, by avoiding profit leakage below the floor, a world-class Floor Price system should have some variation to take into account channels and countries (it is implicitly understood that floor prices of course vary by product), so that differences in competitive levels, market attractiveness or other strategic reasons can be followed.
