Cost-per-click formulas
CPC = cost ÷ clicks. Reverse modes use cost = CPC × clicks and clicks = cost ÷ CPC.
Worked example
$500 divided by 1,000 clicks gives a $0.50 CPC.
Interpretation boundary
Theoretical reverse-solved counts are not silently rounded; a nearest whole count is labeled separately. This calculator does not predict bids, auctions, keyword prices, or whether a CPC is good or bad.
