Best for farms selling weekly produce boxes, market bundles, holiday boxes, or mixed farm-share bags. Updated .
What goes in the box
Retail is what the item sells for on its own at your stand or market. Cost is what it costs you to grow or buy it.
Packing and pricing
Box price and margin
Box price = retail value × (1 − discount). Margin = (price − cost) ÷ price. Max discount = 1 − (cost ÷ (1 − minimum margin)) ÷ retail value. Retail values are your own list prices; the tool does not check what a competitor charges.
About the produce box price calculator
A produce box is a bundle, and bundles are priced two ways at once: against what the items would cost separately, and against what the box costs you to fill. This calculator does both. Enter up to ten items with quantity, retail value each, and cost each, add packing minutes at your labor rate and the cost of the box or bag, and it returns the retail value, the box price at the discount you want to advertise, the margin at that price, and the largest discount that still meets your minimum margin. Weekly and season totals follow from the boxes you plan to sell.
It suits weekly market boxes, one-off holiday boxes, farm-share bags sold week to week, and bundles listed in an online farm store.
Retail value, cost, and the discount
Retail value is the sum of quantity x retail each for every item, using your own stand or market prices. Box cost is item cost + packing labor + packaging. The box price is retail value less your target discount, and the customer saving is the difference, which is the line to put in the listing. Penn State Extension describes bundle and multiple-unit pricing as standard tools for farm markets; the discount is what makes the bundle attractive, and the margin check is what keeps it from being a giveaway.
The maximum discount your margin allows
Margin is profit as a share of the box price: (price - cost) / price. The floor price that meets your minimum margin is cost / (1 - minimum margin), and the maximum discount is one minus that floor divided by retail value. If your target discount is larger than the maximum, the card turns red and shows both the floor price and the discount that would work. Fix it by trimming an expensive item, adding a high-margin one, or reducing the discount.
Weekly and season totals
Multiply by boxes per week and weeks in the season to see revenue and profit for the program. If the box is a recurring subscription, the farm subscription revenue calculator adds churn and signups; if it is part of a CSA, the CSA share price calculator prices the whole season from a budget instead of item by item.
Worked example
A box with 2 heads of lettuce ($3.75 retail, $1.20 cost), 3 lb of tomatoes ($4.00, $1.50), a bunch of carrots ($3.00, $1.00), a bunch of kale ($3.50, $1.10), 2 zucchini ($2.00, $0.60), and a dozen eggs ($6.00, $3.00) has a retail value of $36.00 and an item cost of $13.20. Six minutes of packing at $18 an hour adds $1.80 and the box costs $1.25, so the box cost is $16.25. At a 15% discount the box sells for $30.60, saving the customer $5.40, with $14.35 profit and a 46.9% margin. A 40% minimum margin sets a floor price of $27.08 and a maximum discount of 24.8%. Selling 25 boxes a week for 20 weeks brings $765 a week and $358.75 profit, or $15,300 and $7,175 for the season.

Frequently asked questions
How do I price a produce box?
Add up the retail value of the items, take off the discount you want to advertise (10 to 20% is common), then check that the price still covers item cost, packing labor, and packaging with your minimum margin. If it does not, change the contents or the discount, not the margin.
What margin should a farm produce box make?
Most farms want the same margin on a box as on the items sold separately, less a small allowance for the volume and predictability a box brings. Many land between 35 and 50% after packing labor and packaging; the calculator shows yours at any discount.
How big a discount can I offer on a bundle?
The maximum discount is 1 - (cost / (1 - minimum margin)) / retail value. A $36 box that costs $16.25 to fill can be discounted up to about 25% and still hold a 40% margin. Past that point the bundle sells the farm's work below what it is worth.
Should I count my packing time?
Yes. Six minutes a box at $18 an hour is $1.80, which on 25 boxes a week for 20 weeks is $900 of labor the price should recover. Time the packing of a few boxes and enter the average.
