About this tool
CPC Calculator is a free, in-browser tool for cost-per-click advertising. Choose whether to solve for CPC, total cost, or clicks; the selected field is hidden and the remaining two are used to compute the answer. Add an optional impressions figure and the tool also derives your click-through rate and CPM. Everything runs locally — nothing is uploaded.
The core relationship is CPC = cost ÷ clicks, which rearranges to cost = CPC × clicks and clicks = cost ÷ CPC. When impressions are supplied, CTR = clicks ÷ impressions × 100 and CPM = cost ÷ impressions × 1,000 are shown as extra tiles so you can see click efficiency and reach cost together.
Use it to check a PPC bid, to work out how many clicks a budget buys at a target CPC, or to convert between the click and impression views of the same campaign. Money values are formatted as currency and rates carry a percent sign.
