Cost = per-user price × users (or the plan's flat price / base price plus extra users), at the monthly price or the per-month price of annual billing (yearly cost = 12 × that). Each vendor counts usage in its own unit and units are never converted. A plan marked free is priced as one free account per person. Taxes, add-ons and trials are not included. Ties are broken by vendor name. Affiliate status is never used.
