Jam Profit Margin: Jar by Jar, Market and Wholesale

A small jam maker can earn a gross margin around 50% on jars sold at a market, once the cook's time is counted, and much less wholesale. Margin = (price − cost) ÷ price, where cost is the fruit, sugar and pectin, the jar, lid and label, the labor and the card fees. In the example below, an 8-ounce jar costs $5.76 to make and sell at the market and goes for $11.00, a 47.6% margin. A month of four ways of selling brings $4,440 of sales and about $1,930 of gross profit. The margin leaks through fruit bought out of season, and through jars that ship and break.

The short version

• Margin = (price − cost) ÷ price; markup = (price − cost) ÷ cost.
• Count the cook's time as a cost.
• An 8-ounce jar: $5.76 at the market, $11.00, 47.6%.
• The jar, lid and label cost almost as much as the fruit.
• Online sales carry shipping that has to be priced in.
• Wholesale earns less; check it against full cost.
• TaroStack costs each jar from what each batch used. More below.

A jar, costed

Rappahannock Pantry, the made-up home food maker in Fredericksburg, Virginia, cooks peach jam 24 jars at a time:

Margins by channel

Shipped jars earn the least: the box and padding add $1.10 a jar. The gift set earns the most per sale.

A month's numbers

A September month for Rappahannock Pantry:

The market jars carry the month; the online orders, with shipping supplies, earn 41.6% against 47.6% at the market. Virginia's home food exemption doesn't allow wholesale to shops, so that channel waits for a licensed kitchen, and the step after that is in jam co-packer.

Get the calculator

Download the jam margin calculator. One sheet: one line for each product and channel, with its price, materials, packaging, labor and fee rate; the cost, gross profit, margin, markup and the price your target margin needs 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 holds one cost a jar. Strawberries in June and peaches in August cost different amounts, and the shelf holds both.

How TaroStack does it

TaroStack costs each jar from what each batch used, so margins sit on real cost.

True cost from the batch. Each batch takes fruit and sugar at the price of the deliveries they came from, so a price rise shows in the next batch's cost.

Labor on the batch. The minutes a batch took are recorded on it, so the hours behind each product are on record.

Margins by product. Margins are reported per product on that actual cost, and a price-creep report per supplier shows whose prices moved.

Recipes, batches, costing and margin reports 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.

Questions people also ask

What is a good profit margin for a jam business?

In the example, 47.6% on direct sales before overhead; wholesale earns less, so a business that sells both should know its mix.

Is a jam business profitable?

It can be: the example's month of $4,440 in sales leaves about $1,930 of gross profit, before rent, insurance and the owner's pay.

What is the markup on jam?

In the example, a market jar marks up 91% on its cost.

Should I sell jam wholesale?

Only at a price that leaves something after full cost, and only where your license allows it; the example's home food exemption doesn't.
