Best for cottage food producers and farms making jams, baked goods, sauces, soaps, and other value-added products. Updated .
Ingredients in one batch
For each line, enter how much the recipe uses and what you paid for the package it came from, in the same unit (lb, oz, cups, or count).
Batch, packaging, and labor
Cost and price per unit
Ingredient cost = package price ÷ package quantity × quantity used. Batch cost = ingredients + units × (packaging + label) + labor hours × rate + overhead. Cost per unit = batch cost ÷ units; target price = cost ÷ (1 − margin). This is a costing tool, not a cottage food law tool: check your state's rules on allowed products, labeling, and sales limits.
About the value-added batch cost calculator
A jar of jam costs more than the fruit in it. This calculator costs one batch of a value-added product from up to eight ingredient lines (how much the recipe uses against what you paid for the package), packaging and labels per unit, labor hours at your rate, and batch overhead such as kitchen rental and energy. It returns batch cost, cost per unit, the share of cost that is ingredients, a target price at your margin, profit and margin at the price you plan to charge, and how many units of the batch must sell to break even.
It is for cottage food producers and farms turning surplus into shelf-stable products, and it works for anything made in batches: jam, salsa, baked goods, granola, soap, candles.
Costing the ingredients
Each line takes the quantity the recipe uses and the price and size of the package it came from, in the same unit. Ingredient cost is package price ÷ package quantity × quantity used, so a 10 lb bag of sugar at $9 costs $0.90 per pound and a recipe using 4 lb spends $3.60. Farm-grown produce should be entered at what it would sell for, not at zero, or the product will look more profitable than selling the fruit fresh.
Packaging, labor, overhead, and the price
Penn State Extension's Food for Profit series separates variable costs, which rise with every unit (ingredients, labor, packaging, commissions), from fixed costs, which stay the same regardless of volume (rent, insurance, utilities, loan payments). This tool treats packaging and labels as per unit, labor and ingredients as per batch, and lets you spread fixed costs into the overhead line per batch. Cost per unit is batch cost divided by units, and target price is cost per unit divided by one minus your margin.
Break-even units is the number of units from this batch that must sell at your planned price to cover the batch, rounded up. If it is close to the batch size, the price is too low or the batch too small.
Worked example: a dozen half-pints of strawberry jam
Four pounds of strawberries from an 8 lb flat at $24 cost $12.00; 4 lb of sugar from a 10 lb bag at $9 cost $3.60; a $3.50 box of pectin and a quarter cup of lemon juice from a $4 bottle holding 2 cups ($0.50) bring ingredients to $19.60. Twelve jars at $1.10 each ($13.20) and labels at $0.30 ($3.60), 1.5 hours of labor at $20 ($30.00), and $10 of overhead make the batch $76.40, or $6.37 per jar; ingredients are 25.7% of cost and labor 39.3%. A 40% margin gives a $10.61 target price. At a planned $8.00, profit is $1.63 per jar, a 20.4% margin, $19.60 on the batch's $96.00 of revenue, and 10 of the 12 jars must sell to break even.

Frequently asked questions
How do I calculate the cost of a batch of jam?
Add ingredient cost (package price divided by package size, times the amount used), jars and lids, labels, your hours at a real wage, and a share of kitchen and utility costs. Divide by the jars the batch yields. For a typical dozen half-pints, ingredients are often only a quarter of the cost; jars and labor are the rest.
What margin should a cottage food product have?
Many small producers target 30 to 50% of the selling price after all costs including labor, because market fees, samples, and unsold product eat into it. If the target price comes out above what customers will pay, look at batch size, packaging cost, and labor per batch before cutting the margin.
Should I count my own labor?
Yes. Prep, cooking, filling, cleanup, and labeling are hours you could spend elsewhere. Pricing without labor is how a product that sells out every week still loses money once you scale it.
Does this cover cottage food laws?
No. It is a costing tool. Which products you may sell from a home kitchen, how they must be labeled, where you may sell them, and any annual sales cap are set by your state's cottage food law or department of agriculture. Check those before pricing.
