Click-through rate (CTR) is the percentage of people who click your ad or link after seeing it. The CTR formula is:
CTR = (Clicks ÷ Impressions) × 100
Example: 50 clicks from 5,000 impressions is a 1% CTR. The calculator above gives you CTR, CPM, and CPC together.
What is CPM?
CPM is the cost per 1,000 impressions — how much you pay for visibility:
CPM = (Cost ÷ Impressions) × 1,000
What is CPC?
CPC is the cost per click — how much each click costs you:
CPC = Cost ÷ Clicks
What is a good CTR, CPM, and CPC?
Benchmarks vary by platform and industry, but a search-ad CTR around 2 to 5% and a display CTR near 0.5% are common. CPM and CPC depend heavily on competition and targeting, so track them over time and compare against your own baseline rather than a generic number.
How CTR, CPM, and CPC relate
They are three views of the same campaign: CTR measures engagement, CPM measures the cost of reach, and CPC measures the cost of action. A high CTR usually lowers your CPC, because ad platforms reward relevant ads with cheaper clicks.
