A simple cost sheet for a jar of starter, with a worked example and the mistakes that eat your margin.
On this page
What to remember
- Cost the feedings, the jar, your time, and your monthly shop fee.
- Add a margin after every cost, not before.
- Check your state rules before you take orders.
- Raise the price or shrink the jar if the math does not work.
The number you land on should come from your own jar, not from a copied price list. This guide shows how to work out how much to sell a sourdough starter for with a cost sheet, a worked example, and the checks that keep a low price from costing you money.
What goes into the cost of one jar?
Start with the flour and water you use to feed the starter you sell. Then add the jar, lid, label, and bag. Add the minutes you spend feeding, filling, and labeling. Finally, add a share of your monthly costs, such as your Brevl shop at $20 a month with 0% commission.
If you want the feeding math first, see how much sourdough starter costs. That guide covers the flour and water side. This page covers the price you charge.
Cost the feedings for one jar
Track the flour and water you use from the starter you keep for sales. A small notebook or a spreadsheet is enough.
Add the jar, lid, label, and bag
Use your real receipt. If you deliver, add the box and the drive.
Put a dollar value on your time
Pick an hourly rate and multiply it by the minutes you spend on one jar.
Spread your monthly costs across jars
Add your Brevl fee and any market fees, then divide by the jars you expect to sell.
Add a margin and check the price
A margin is what is left after every cost. Pick a price that leaves a profit and still fits your buyers.
Keep your cost sheet to four lines: ingredients, packaging, labor, and overhead. That is enough to see if a price works. You do not need a complex system to price one jar.
What does a worked example look like?
Say you sell 20 jars a month. Your Brevl shop costs $20 a month with 0% commission, so that is $1 per jar. For this example, use $1.20 of flour and water, $0.80 for the jar, lid, and label, and 12 minutes at $15 an hour, which is $3.00. Your cost is $6.00 per jar. At $12, your margin is $6.00, or 50%.
The same $20 fee changes your cost per jar. If you sell 10 jars, overhead is $2 per jar. At 40 jars, it is $0.50 per jar. More jars spread the fee, but only if you can make and sell them without rushing.
If you take card payments through your own Stripe or Square account, check the fees before you call the margin final. Brevl does not take a cut of your sales, but your payment processor may charge a fee. If you also sell loaves, how much to charge for sourdough uses the same cost method.
What should you check before you set a price?
Check the rules for your state before you sell. Ask your local health department what is allowed for a starter sold from home. Then check your numbers. A price that works on paper can fail if you forget the jar, the label, or the drive to the drop-off.
Which mistakes cost you money?
The first mistake is not paying yourself. If you leave your time out, a $6 jar can look profitable when it is not. The second is giving away too much starter. Every free jar is a jar you paid to make. The third is counting only the flour. The jar, label, and bag can cost more than the flour and water. Check your own receipt.
Do not set a price from one week of sales. Track a few months of jars, costs, and messages. That shows you which price your buyers accept and which costs keep coming back.
How do you raise the price without losing buyers?
Explain what makes your starter worth the price. A clear label, a feeding card, and a jar that is ready to use can justify more than a plain jar with no information. If buyers still push back, offer a smaller jar at a lower price instead of cutting the price on the same jar.
Do not apologize for the price. State what is in the jar and how to feed it. If you sell bagels too, how much to sell sourdough bagels for shows the same math.
For the bread side of your shop, see how much homemade sourdough sells for. It helps you compare a jar of starter with a loaf before you decide where to spend your time.
When is a starter not worth selling?
If your cost per jar is $6 and your buyers will only pay $7, you are working for $1 before fees. That is not a business. Raise the price, shrink the jar, or sell a different item. You can also sell starter as part of a baking bundle if the bundle covers your costs.
A starter can bring buyers who also order bread. Count that when you compare it with other items. If bread is a better fit, use how much to sell sourdough bread for to compare.
How do you keep the math after the first sale?
Update your cost sheet when flour, jars, or labels change. Check your monthly shop fee against the number of jars you sell. If you sell fewer jars, your cost per jar goes up. Brevl has recipes with real costing, ingredient inventory, and a weekly planner, so you can price and plan. One flat $20 a month, no cut of your sales.

Common questions
Can I sell a sourdough starter from home?
Check the rules for your state before you take money. Ask your local health department what is allowed for a starter sold from home. Keep records of what you sell and where you sell it. A clear answer from your state is worth more than a guess.
Should I sell active starter or dry starter?
Sell the one you can make safely and explain it clearly on the label. The price should match the work and the packaging each one needs. Do not copy a price from a different product. Check your own cost before you list it.
How do I count my time in the price?
Pick an hourly rate you would pay someone else. Multiply it by the minutes you spend on one jar. Include feeding, filling, labeling, and answering messages. If you spend 12 minutes at $15 an hour, that is $3.00 per jar.
What if buyers say my starter is too expensive?
Do not cut your price below your cost. First check your jar size, your packaging, and your time. A smaller jar or a simpler label can lower the cost. If the price still does not work, sell a different item or find buyers who value a ready-to-use starter.
Do I need to charge sales tax on starter?
Sales tax rules depend on your state and on how you sell. Keep every receipt and ask a tax professional who knows your state. Do not guess. A clear record of sales and costs makes the question easier to answer at tax time.
General information, not legal, tax, or food safety advice. Check your state cottage food rules and talk to a tax professional about sales tax and income tax.
