Normalize the quotation
Choose a single currency and enter the rate per unit per billing period. Multiply by the quantity and number of periods, then include supplier discounts and additional charges. Convert currencies independently before entering values; this tool does not fetch exchange rates.
Use like-for-like audience data
Optional impressions must cover the entire quoted quantity and campaign period. Effective CPM divides the net cost including extras by those impressions and multiplies by one thousand. Leave impressions blank when they are unavailable instead of inventing an audience estimate.
Compare beyond cost
A lower CPM does not mean better reach, viewability, targeting or business results. Check inventory quality, location, frequency, make-goods, cancellation rules, measurement and tax treatment. Quotes are alternatives rather than a combined campaign budget; the comparator deliberately avoids summing them into a recommended purchase.
