How do you calculate CPC?

Divide the spend by the clicks. A spend of 120 across 60 clicks is $120.00 / 60 = $2.00 a click, and the page prints that substituted division under the figure so the answer can be checked rather than trusted. Where the division does not land on a round number of cents, the cents are shown with the longer figure beside them: 100 across 3 clicks is $33.33, printed next to the 33.3333333333333 the division actually gives.

How many clicks will a budget buy, and what will a number of clicks cost?

Set Solving to Clicks and the page divides the budget by the price: $1,440.00 at $2.25 a click is 640 clicks. Set it to Spend and it multiplies instead: 640 clicks at $2.25 each is a spend of $1,440.00. Switching between the three hands the answer you just solved back into the box it came from, so the campaign you were describing stays intact: the one exception is an estimated click count, which is not a whole count the box can hold.

Why is a solved click count sometimes labelled an estimate?

Because a click is a counted event and the division does not always land on one. $100.00 at $2.25 a click divides into 44.44 clicks, which is not a count anyone delivered, so the page labels it an estimate and prices the whole count either side: 44 clicks cost $99.00 and 45 clicks cost $101.25. Rounding it to 44 in silence would hand you back a count at a price nobody paid, which is the quiet error this page is built to avoid.

Which currency is the answer in?

Whichever one you label it with. The Currency box takes a symbol or a code of up to six characters and prints it in front of every money figure, so a label of $ gives $2.25 and a three-letter code gives USD 2.25, printed in capitals. Empty the box and the figures print with no label at all. Nothing here is converted: the spend and the cost per click are read as the same currency, which is why changing the label never changes the answer.

Why does it refuse a click count with a decimal point in it?

A click count is a whole number of counted events, so 60.5 is refused with both neighbours named: enter 60 or 61. The one place a part of a click appears is in an answer, when the page has solved for the count itself, and there it is labelled an estimate with the whole counts either side priced for you. What you typed stays in the boxes while you fix it.

Is CPC the same as CPM, CTR, RPM or eCPM?

No, and this page does not convert between them. CPC prices one click, spend divided by clicks. CPM prices a thousand impressions, so it is paid whether or not anyone clicks. CTR is the share of impressions that were clicked, a rate rather than money. RPM and eCPM describe money a publisher receives for a thousand impressions, which takes figures this page never asks for, so it makes no claim about what a campaign will bring in.

Does the page say what a click ought to cost?

No, and that is on purpose. A cost per click only means something beside the auction, the keyword, the placement and the audience it came from, so a single figure published as a target would be wrong for most of the people reading it. What you get here is the arithmetic: the cost per click, the division that produced it, and the two figures you entered, all printed together.

Do my numbers leave the browser?

No. The division happens in the page itself, with no upload, no account and no sign-up. What you last typed is kept in this browser so the page opens where you left it, and the Start over button at the top of the page forgets it. The site counts that this tool was opened and nothing else: not your spend, not your clicks, and not any figure on the page.

CPC Calculator

Cost per click is one division: the spend divided by the clicks. This page does that division and prints the substituted arithmetic beside the answer, so 120 of spend across 60 clicks reads $2.00 with $120.00 / 60 = $2.00 under it. Enter any two of the three figures and it solves the third, so $1,440.00 at $2.25 a click is 640 clicks, and 640 clicks at $2.25 is a spend of $1,440.00. The currency is a label you type rather than one the page guesses: a symbol sits in front of the figure, a three-letter code sits in front with a space, and nothing is converted between two currencies. Clicks are counted events, so the box takes whole ones, and a count the page solves for that lands between two whole clicks comes back as an estimate: $100.00 at $2.25 is 44.44 clicks, printed with 44 clicks at $99.00 and 45 clicks at $101.25 beside it rather than rounded to one of them. No account, nothing gated, and the figures stay in your browser.

Fill in any two boxes and the third is the answer. A k, m or b ending is read, so 12k clicks is 12,000, and the label beside the money is whatever you type: a symbol sits in front of the figure, a three-letter code sits in front with a space, and an empty box prints the figures bare.

One click, not a thousand impressions. Cost per click divides the spend by the clicks, so 1,440 across 640 clicks is 2.25 a click. That is a different figure from CPM, which divides by impressions and then multiplies by a thousand, and from click-through rate, which is the share of impressions that were clicked. Nothing here turns a cost into a publisher payout: RPM and eCPM describe money coming in for a thousand impressions, and no arithmetic on this page converts between the two.

What a click count can and cannot be. Clicks are counted events, so the box takes whole ones, and a count this page solves for that lands between two whole clicks is labelled an estimate with both counts priced beside it. Exact arithmetic: cost per click is spend divided by clicks, in the currency you label it with. Enter any two and the third is solved, and a solved click count that lands between whole numbers is shown as an estimate rather than quietly rounded. It computes the stated formula, converts to no publisher metric and forecasts no earnings.
