Your own result may differ because it uses the exact values you enter. For comparisons, keep the method and units consistent from one calculation to the next.
Important assumptions and limitations
Impressions are ad displays, not unique people. CPM alone does not measure clicks, conversions or profitability.
Calculator outputs are estimates unless the underlying arithmetic is exact by definition. For decisions involving tax filing, lending, health, contracts or institutional grading rules, use the calculator as a first check and confirm the final decision with the relevant authoritative source.
