Google gives AdSense users 68% of the total earnings from their ad units. Here’s how the calculation would work if you had an ad that received 100 clicks and the advertiser had bid $1.00 on it: 100 * 1.00 *.68 = $68

Currently, AdSense publishers receive 68% of the click cost and Google 32%. This means that if an advertiser pays $1 for each click on his ads, the AdSense publisher will get $0.68 and Google $0.32. The amount of money you can make varies per ad type and format.

For every click a user makes on an Adsense Ad, Google will pay you a certain amount (from a few cents to a few dollars). So, the amount of money you will make from AdSense depends on the number of clicks your ads receive.
