The Google AdWords Price Calculator allows marketers to gauge an estimate of their Google AdWords cost. This calculator takes into account two input values: the estimated number of clicks per day and the cost per click.

To use the calculator, follow these steps:

1. Input the estimated number of clicks you expect your ad to receive each day in the ‘Estimated Clicks Per Day’ field. This estimate could be based on your keyword reach, targeting options, and overall budget.
2. Next input the cost per click into the ‘Cost Per Click’ field. This value is the amount you are willing to pay for each click on your ad, and is often determined by factors such as keyword competition and relevancy.
3. Click the ‘Calculate AdWords Spend’ button. The calculator will then multiply the estimated number of clicks by the cost per click to give you a total estimated Google AdWords spend.
4. The result will be displayed under the ‘Calculate AdWords Spend’ button.

Remember, while this tool provides a basic estimate, actual costs can vary. Google AdWords operates in a live auction environment, so costs can fluctuate based on factors such as competition, changes in advertising budgets, and changing market conditions.
