Help > Adwords - Cost Per Day
This is the estimated total daily cost of running your ad, based on the maximum CPC you have set.
The quick formula for daily cost is: estimated clicks per day multiplied by the average CPC.
These values are rounded to the nearest cent for your convenience, and may not match exactly.
Remember the daily cost figure when setting your daily budget.
If you set your daily budget lower than this estimated daily budget, your ads may not receive maximum exposure.
