Wholesale Jam Jars: Case Price, Jar Size, and Margin
A clear way to price a case of jam jars so your homemade jam still makes money.

What to remember
- Cost per jar is the delivered case price divided by the number of jars.
- Lids and seals can be sold separately. Check before you buy.
- A sample jar tells you more than a photo on a website.
- Buy a small case first. You can always order more.
If you sell jam from home, the jar is often the second biggest cost after the fruit. Buying wholesale jam jars in the right size and quantity keeps that cost down. This guide walks through the numbers and the checks that save you money.
Buying wholesale jam jars means you pay less per jar than at a grocery store. But the lowest case price is not always the best deal. Shipping, lid cost, and minimum order can change the real cost. Always compare the delivered cost per jar.
What does a wholesale jam jar cost you?
The cost per jar is not just the case price. Add the shipping and any tax, then divide by the number of jars in the case. If lids are not included, add the lid cost per jar. That number is your true cost for one empty jar.
How to compare jar sizes and lid types
Jam jars come in many sizes, from 4 ounces to 16 ounces. The size you pick changes your label, your price, and how many jars you need per case. A smaller jar can sell for more per ounce, but it takes more time to fill. Check the lid type too. A two piece lid and a one piece lid need different sealing methods.
How to calculate your overhead per jar
Overhead is every business cost that is not ingredients or labor. That includes your Brevl subscription, your phone, your market fees, and your car mileage. Add those up for a month. Divide by the number of jars you sell in that month. That is your overhead per jar. If your Brevl cost is $20 and you sell 20 jars, that is $1 per jar.
Work out your cost per jar and your margin
Get the delivered case price
Ask the supplier for the total price including shipping and tax to your address.
Count the jars in the case
Check if lids are included. If not, add the lid cost per jar.
Divide the delivered price by the jar count
That is your cost per empty jar.
Add your jam ingredients per jar
Fruit, sugar, pectin, lemon juice, and any other ingredient you use.
Add your labor per jar
Decide an hourly rate for yourself and divide it by the jars you fill in an hour.
Add your overhead per jar
This includes your Brevl subscription, utilities, and any other business cost. Divide your monthly overhead by the jars you sell in a month.
Set your price and check the margin
Your price minus all three costs is your margin. If the margin is too thin, change the jar size or the price.
For example, say a case of 12 jars costs $15 delivered. That is $1.25 per jar. Your fruit and sugar cost $2.00 per jar. Your labor is $0.50 per jar. Your Brevl cost is $20 a month, and you sell 20 jars, so $1.00 per jar. Your total cost is $4.75. If you sell at $8.00, your margin is $3.25 per jar. These are example numbers. Use your own.
Mistakes that cost you money on wholesale jam jars
What to check before you commit to a case
Ask for a sample jar before you buy a full case. Check the return policy and the lead time. If you sell at a farmers market, make sure the jar size fits your label and your state cottage food rules. The laws about selling homemade jam guide covers label rules. For a full cost per jar example, see As Ever Jam Price.
Ask the supplier for the delivered price, the jar count, the lid type, the minimum order, and the lead time. Ask if they will send a sample. Ask about the return policy. Write down the answers so you can compare suppliers.
The jar size decides your label size. A small jar has less room for your ingredients and your business name. Check your state label rules before you print. The laws about selling homemade jam guide has the details.
Glass jars take up space. Store them in a dry place away from sunlight. Keep the lids on to keep the inside clean. If you buy a large case, make sure you have room before it arrives.
Once you know your best selling jar, set a reorder point. When you have two cases left, order more. That gives you time for shipping. It also keeps you from running out at a market.
Some home bakers split a large case with a friend. That can lower the cost per jar without a big cash outlay. Just agree on how you will divide the jars and the shipping.
Your price must cover the jar, the ingredients, your labor, and your overhead. Then add a profit margin. A common starting point is to double your cost. But check what your market will pay. If the price is too high, change the jar size or the recipe.
There is no fixed margin. A margin that pays you for your time and leaves money for growth is the goal. Use the worked example above to see how the margin changes when you change the jar size or the price.

Common questions
How many jars should I buy at once?
Start with a small case, enough for one or two market days. That lets you test the jar and the lid before you spend more. Once you know your sell through, order a larger case to get a lower cost per jar.
Do wholesale jam jars come with lids?
Not always. Some suppliers sell jars and lids together. Others sell them separately. Always check the product description or ask the supplier. If lids are separate, add that cost to your cost per jar.
What size jar sells best for homemade jam?
There is no single best size. A 4 ounce jar is good for gifts and samples. An 8 ounce jar is a common size for market sales. A 16 ounce jar gives a lower cost per ounce but a higher price at the table. Test what your customers buy.
Can I use wholesale jam jars for cottage food sales?
Yes, as long as the jar and lid meet your state cottage food rules. Some states require new lids and a specific seal. Check your state rules before you buy a large case. The label rules guide on this site has more.
How do I compare the cost per jar from two suppliers?
Ask both for the delivered price to your address. Divide that by the number of jars. If lids are separate, add the lid cost. Then compare the total cost per filled jar, not just the empty jar price.
Should I buy jars online or from a local store?
Online often has a lower case price but higher shipping. A local restaurant supply store may let you pick up and avoid shipping. Compare the delivered cost per jar for both. Also check the lead time if you need jars soon.
