Every plan computes the whole grid. The plans differ in who can edit, where data comes from, and how many cells one run may produce.

A company with its own security review and its own warehouse.
Every plan runs the same engine. A model computes every driver at every slice at every step, every roll-up is in the answer, and every value says where it came from. No plan turns off a feature of a formula.
A grid is drivers times slices times steps. A model with 20 drivers, 12 slices, and 36 monthly steps produces 8,640 cells in one run. A run that would produce more cells than your plan allows does not start, and it reports the counts that made it too big.
Cells are counted per run, not per month. Running a model again does not use up anything.
Move between Personal and Team at any time. Your projects, tables, and models stay as they are, and a project over the Personal limits stays readable when you move down.
