CTR & CPC Calculator

Your click-through rate and cost per click from the numbers in your ad manager, with what Pinterest clicks are reported to cost.

Click-through rate and cost per click

1.5% CTR

$0.50 per click

300 clicks ÷ 20,000 impressions = 1.5%
$150.00 ÷ 300 clicks = $0.50 per click
$150.00 ÷ 20,000 impressions × 1,000 = $7.50 CPM

Google Ads Help: “CTR is the number of clicks that your ad receives divided by the number of times your ad is shown: clicks ÷ impressions = CTR.”

What a Pinterest click is reported to cost

WebFX (a survey of 270 marketers): 43% paid under $0.10 per click. Yours is above that range. How Much Does Pinterest Advertising Cost in 2026?
Admetrics (an ad-analytics company's guide for e-commerce brands): $0.10–$1.50 per click. Yours is inside that range. How Much Do Pinterest Ads Cost? (Silvana Chirita, 23 October 2025)

Definition: Google Ads Help, "Clickthrough rate (CTR): Definition". Checked 29 September 2026. Two published Pinterest ranges are shown side by side, never averaged. No “good” CTR is given: compare your own campaigns.

Quick answer: click-through rate (CTR) is clicks ÷ impressions, shown as a percentage: 300 clicks on 20,000 impressions is 1.5%. Cost per click (CPC) is cost ÷ clicks: $150 for 300 clicks is $0.50. Type your own numbers above for both, with the sum behind each. On Pinterest you can count Pin clicks or outbound clicks, and each gives its own rate.

How to use it

Choose what counts as a click: any ad, or on Pinterest a Pin click or an outbound click.
Type the impressions and the clicks for the CTR, and the cost for the CPC. Numbers can be typed as ad managers show them: 12.5k, $1,250 or 2.5m.
The rate, the cost per click and the CPM appear with their sums. Copy link keeps the numbers, so you can compare campaigns.

The two formulas, in Google's words

CTR: "CTR is the number of clicks that your ad receives divided by the number of times your ad is shown: clicks ÷ impressions = CTR." Google's own example: "For example, if you had 5 clicks and 100 impressions, then your CTR would be 5%." (Google Ads Help, "Clickthrough rate (CTR): Definition".)
CPC: "Average cost-per-click (avg. CPC) is calculated by dividing the total cost of your clicks by the total number of clicks." (Google Ads Help, "Average cost-per-click (Avg. CPC): Definition".)

The same two divisions work for any network. What changes from one network to the next is what it counts as a click.

On Pinterest, a click is one of two things

Pinterest's analytics reports two click rates, and it defines both (Pinterest Business Help, "Pinterest Analytics"):

Pin click rate: "The total number of clicks from your Pin or ad to content on or off Pinterest, divided by the total number of times your Pins or ads were on screen."
Outbound click rate: "The total number of clicks to the destination URL associated with your Pin divided by the total number of times your Pins were on screen."

A Pin click includes people opening the Pin to look closer; an outbound click is someone leaving Pinterest for your website. If the goal is visitors, the outbound click rate is the one to watch, and your cost per outbound click is what a visitor really costs you.

What a Pinterest click costs

Pinterest does not publish a typical cost per click. Two sources do, and they disagree:

WebFX, from a survey of 270 marketers: 43% paid under $0.10 per click (How Much Does Pinterest Advertising Cost in 2026?).
Admetrics, an ad-analytics company writing for e-commerce brands: a CPC that "typically ranges between $0.10 and $1.50" (How Much Do Pinterest Ads Cost?, Silvana Chirita, 23 October 2025).

The calculator tells you where your own CPC sits against each, side by side. It never averages them: an average of two ranges that disagree is a number nobody measured.

Is my CTR good?

This page does not print a "good" CTR, because a rate means little without the ad, the audience and the goal around it. The useful comparison is your campaign against your own earlier campaigns, worked out the same way. For impressions and budget, the CPM calculator works out what a budget buys; for organic Pins, the engagement rate calculator adds saves to the clicks, the way Pinterest's engagement rate does.

FAQ

How do you calculate CTR?

Divide clicks by impressions and multiply by 100. 300 clicks on 20,000 impressions: 300 ÷ 20,000 × 100 = 1.5%.

How do you calculate cost per click?

Divide what you spent by the number of clicks. $150 for 300 clicks: $150 ÷ 300 = $0.50 per click.

What is the difference between CPC and CPM?

CPC is what you pay per click; CPM is what you pay per 1,000 impressions. With both the cost and the impressions typed, this page shows the CPM too: $150 on 20,000 impressions is a $7.50 CPM.

Is Pinterest's Pin click rate the same as CTR?

It is Pinterest's click rate for any click on a Pin, including one that opens the Pin on Pinterest. Its outbound click rate counts only clicks to your website. Both are clicks divided by impressions; they count different clicks.

Why can't clicks be more than impressions?

A click needs the ad on screen first, so every click comes with an impression. More clicks than impressions usually means a digit is missing from one of the numbers, and the page says so instead of printing a rate over 100%.
