Lawn Fertilizer Calculator

Calculate lawn fertilizer bags needed per application and per year.

Annual Bags
— bags per year
All applications.

Usage Tip

Follow the bag’s recommended rate and do not double up; over-fertilizing burns the lawn and runs off into waterways.

THE MATH
bags per application = round up( lawn area ÷ coverage )
annual bags = bags per application × applications
Fertilizer bags per application come from the lawn area divided by the bag coverage. Multiply by the number of feedings a year for the annual total.
Enter the lawn area, the coverage per bag, and how many applications you do per year.
Bags per application round up to whole bags.
