CALCULATION PRINCIPLES

How MARKMA calculates

We document calculation formulas, assumptions and limits. Editorial material shows when it was last reviewed.

Methodology and limits
  1. 01The calculation horizon is explicit: first purchase and repeat purchases are separate.
  2. 02Money is calculated precisely; rounding happens only when a result is displayed.
  3. 03When division is undefined, the result is reported as unavailable, never as Infinity or NaN.
