How to Use This Calculator

Enter your field size in acres, then enter costs and application counts for bio-insecticides, beneficial insect releases, row covers, and pheromone traps.
Enter your weekly IPM scouting hours, season length in weeks, and scouting labor rate to estimate monitoring labor cost.
Enter the conventional pesticide cost per application and number of applications for comparison.
Review the Total Organic Pest Cost and Organic Cost Per Acre alongside the Conventional Pest Cost to see the season totals.
Check the Cost Difference Per Acre and Organic Premium (%) to see how much more (or less) the organic program costs versus conventional pest control.

How the result changes with Acres

Acres	Total Organic Pest Cost	Cost Difference Per Acre
5,000	$801,728.00	$110.35
17,500	$2,801,728.00	$110.10
32,500	$5,201,728.00	$110.05
45,000	$7,201,728.00	$110.04

What each input means

Acres: Total crop acreage to protect.
Bio-Insecticide Cost ($/acre/app): Cost per acre per application for Bt, neem, spinosad, etc.
Bio-Insecticide Applications: Number of spray applications per season.
Beneficial Insect Cost ($/acre): Cost per acre for beneficial insect releases (ladybugs, lacewings, etc.).
Beneficial Releases/Season: Number of beneficial insect releases per season.
Row Cover Cost ($/acre): Cost per acre for row cover material (0 if not used).
Row Cover Lifespan (seasons): Number of seasons row covers last before replacement.
Pheromone Trap Cost ($/acre): Pheromone trap and lure cost per acre.
Conventional Pesticide ($/acre/app): Cost per acre per application for synthetic pesticides.
Conventional Applications: Typical number of conventional spray applications.
Scouting Hours/Week: Weekly pest scouting time (organic relies heavily on IPM scouting).
Growing Season (weeks): Length of active pest management season.
Scouting Labor Rate ($/hr): Hourly rate for pest scouting labor.

What each result means

Total Organic Pest Cost: Season total for all organic pest management strategies.
Organic Cost Per Acre: Organic pest management cost per acre.
Conventional Pest Cost: Season total for conventional pesticide program.
Cost Difference Per Acre: Organic minus conventional cost per acre (positive = organic costs more).
Scouting Labor Cost: Total cost of IPM scouting labor for the season.
Organic Premium (%): How much more (or less) organic pest control costs vs conventional.

How this is calculated

Worked example, using the default values

Identify Input Parameters
4 parameters
Acres = 20, Bio-Insecticide Cost ($/acre/app) = 15, Bio-Insecticide Applications = 4, Beneficial Insect Cost ($/acre) = 40 = 13 input(s) provided
Calculate Total Organic Pest Cost
Total Organic Pest Cost = bioInsecticideTotal + beneficialTotal + rowCoverAnnualized + trapTotal + scou...
4928 = $4,928
Calculate Cost Difference Per Acre
Cost Difference Per Acre = organicCostPerAcre - conventionalCostPerAcre
196.4 = $196.4
Calculate Organic Cost Per Acre
Organic Cost Per Acre = totalOrganicCost / acres
246.4 = $246.4
Calculate Conventional Pest Cost
Conventional Pest Cost = conventionalCostPerApp * conventionalApps * acres
1000 = $1,000
