To price a 12-ounce jar of peanut butter you add up its full cost first: the peanuts and salt by the batch, your time at an hourly rate, the jar, lid and label, and a share of overhead like rent and power. That's what one jar costs you. Then set the price so that, after card and selling fees, it leaves the margin you want: price = full cost ÷ (1 − margin − fee rate). For a 12-ounce jar that costs $3.67 to make, a 55% margin after 3% fees means $8.73, rounded up to $9.00. The peanuts are the biggest cost; the roaster, mill and kitchen come next, then the jar and label. A grocer pays less and marks it up on its shelf. In the example below, an Arkansas nut butter maker prices its jars for direct sales and grocers.
The short version
- Full cost = peanuts and salt a jar + your time + jar, lid and label + overhead.
- Price = full cost ÷ (1 − margin − fee rate).
- Count your time at a real hourly rate, even if you don't pay yourself yet.
- Price from the peanuts after roasting and grinding loss.
- Count the roaster, mill and kitchen in the overhead.
- Check what wholesale leaves after full cost before saying yes.
- TaroStack costs each jar from its recipe and what each batch used. More below.
What goes into a jar's cost
| Part | How to count it |
|---|---|
| Peanuts and salt | The batch's cost ÷ jars a batch |
| Your time | Hands-on minutes for the batch ÷ jars × your hourly rate |
| Jar, lid and label | Per jar |
| Overhead | Rent, power, tools, spread over the jars you make |
| Fees | Card and market fees as a share of the price |
The business's year is in nut butter business plan, and the run itself in how to make peanut butter in bulk.
An example: a jar of peanut butter
Red Oak Nut Butters, the made-up nut butter maker in Little Rock, Arkansas, I use in these examples, roasts and grinds about 600 12-ounce jars of peanut butter in a day:
| A day of 600 jars | Amount | Cost |
|---|---|---|
| Raw peanuts | 480 lb | $816.00 |
| Salt | 6 lb | $3.00 |
| A batch | $819.00 |
| A jar | Cost |
|---|---|
| Peanuts and salt, $819.00 ÷ 600 | $1.37 |
| Time, 1,440 minutes for the batch at $20 an hour ÷ 600 | $0.80 |
| Jar, lid and label | $0.65 |
| Overhead | $0.85 |
| Full cost | $3.67 |
At a 55% margin after 3% card fees, the price is $3.67 ÷ 0.42 = $8.73, so $9.00. At $9.00 a jar, each leaves $5.07. The market had said $8.00, which leaves $4.10. Grocers at $5.50 leave $1.67 a jar, and take about 2,500 jars a month. When a co-packer would grind for less is in nut butter co-packer.
Get the calculator
Download the peanut butter price calculator. One sheet: type the batch's ingredients, amounts and costs, the jars it makes, the hands-on minutes, the jar and overhead, your hourly rate, card fees and the margin you want; the full cost, the price for your margin rounded up, and what a wholesale price and a test price leave fill in. It's an ordinary Excel file with no macros, and it works in Google Sheets, LibreOffice and Numbers.
Where this stops working
The calculator prices one day. Peanut prices move by the harvest, a roast that runs long loses more weight, and honey or chocolate jars cost differently.
How TaroStack does it
TaroStack costs each jar from its recipe and from what each batch used.
Recipes by weight. Each jar is a recipe, with unit conversion from the case or sack to the gram.
True cost from the batch. Each batch takes ingredients at their real cost, from the deliveries they came from, so a price rise shows up in the next batch.
Price creep. A price-creep report per supplier shows which ingredient is quietly costing more.
| The job | Spreadsheet | In TaroStack |
|---|---|---|
| What a jar costs this week | Last season's sheet | True cost from the batch |
| Jars by roast date | Marker on the case | Lots with dates, oldest first |
| An ingredient creeping up | Noticed at tax time | A price-creep report |
| Whether wholesale still pays | A guess | Margins on real cost |
Recipes, batches and true cost are on every plan, from $49 a month. The first 30 days are free, with no credit card. If you'd like a hand setting up, ask, and we'll do it with you.
