To calculate the average of monthly sales, you would need sales data for a period of time such as one year. Then you would add up each month's takings and divide by 12, as there are twelve months in a year.
To calculate monthly sales growth a sales company needs to compare the sales from a previous month with that of the current month. If current sales is divided by a previous month sales, the end result will be the percentage of sales growth.
To calculate sales growth over a 5-year period, subtract the sales from the beginning of the period from the sales at the end of the period. Then, divide this difference by the sales at the beginning of the period and multiply by 100 to get the percentage growth.
you use a scientific calculate
((current month's sales - last month's sales)/last month's sales)x100
Assume you have the growth rates for each month, then you: ....
annual sales*(1/365)
1 week Total sales/7
Rate requires that you calculate the growth over time. I grew 10% (Yippee!) ...after operating 50 years (D'oh!).
You can't have negative net sales.
EI = (100 + Product Growth %) / (100 + Market Growth %) X 100

The formula to calculate average sales per hours is P/T. P is the total number of products sold and T is the amount of time it took to sale the products. For example, 100 items told in fives hours has an average sales per of 20.
