How to Sell Sourdough Starters: Jar Cost and $20 Overhead
Figure out what a jar of starter costs you and what to charge so the sale pays.

What to remember
- Price the jar as its own product, not as a loaf.
- Count the jar, lid, label, flour, water, and your time.
- Divide your flat monthly fee by the jars you really sell.
- Check your state cottage food rules before you take money.
- Keep one order list with names, dates, and pickup times.
Once you know how to sell sourdough starters, the hard part is not the flour. The small costs decide whether a jar makes money: the jar, the label, your time, and the fee you pay each month. This guide walks through the math, the rules to check, and the habits that bring buyers back.
What does one jar of starter really cost?
Start with one jar and build the cost from the bottom. You need the flour and water that feed the starter, plus the jar, lid, and label. Then add the minutes you spend feeding, filling, and cleaning. If you skip your minutes, the price will look better than the sale.
A starter is not a loaf, so use a starter guide for the cost. Our guide to fresh sourdough starter covers the fresh jar. Our guide to dehydrated sourdough starter covers the dry version. Use the one that matches what you sell.
Use one cost sheet for every jar size. A half pint and a pint need different numbers, and the sheet keeps them apart.
How do you price a starter when the jar is small?
A small jar still carries a full set of costs. Set a price that covers the jar, the label, your time, and your monthly costs. Then check it against what local buyers already pay for sourdough. Our guide to how much homemade sourdough sells for lists $10 to $18 a loaf. That is a loaf, not a jar, so use it as a market check, not as your jar price.
For example, say one jar sells for $12. Flour and water cost $2.50 with the jar and label. Twenty minutes of your time at $15 an hour adds $5. Brevl costs $20 a month and takes 0% of sales. If you sell 20 jars, that overhead is $1 a jar. Total cost is $8.50. Your margin is $3.50 a jar, or $70 for the month.
Round your price only after you see the full cost. A round number is easier to say, but it can hide a thin margin. If the full cost is $8.50 and you want $3.50, a $12 price works. A $10 price leaves $1.50.
A simple routine to price one jar
Cost the contents
Add the flour, water, jar, lid, and label for one jar. Use the price you paid, not a guess.
Pay yourself
Write down the minutes for feeding, filling, and cleaning. Multiply by the hourly rate you want to earn.
Spread the monthly fee
Take your flat monthly cost, like Brevl at $20, and divide it by the jars you expect to sell.
Set the price
Add your margin to the full cost. Check the result against your local buyers before you print a label.
Check the rules
Read the cottage food rules for your state before you take money. Do not copy a label from another seller.
Write the full cost on a card for each jar size. Then you can change one number, like the jar price, without rebuilding the whole sheet. Keep the card with your order list.
What rules do you check before you sell?
Start with the rules for your state. Our guide to selling sourdough legally covers permits and labels. Read it before you print labels or take money. It is the first thing to check, not the last.
Print a short run first. Then you can fix the wording without throwing away a big stack.
How do you take orders and get paid?
Keep the first step simple. Use one order form, one pickup window, and one way to pay. Brevl lets you take card payments through your own Stripe or Square account, plus Venmo, Cash App, Zelle, and cash. You can run your shop from a phone or a computer, and the shop carries your photos, colors, and web address.
A flat fee is easier to count than a cut of every sale. Brevl costs $20 a month and takes 0% of your sales. There is a 30 day free trial, and you do not need a card to start. That gives you a month to test your price before you pay.
Set a pickup window that you can keep. Do not promise same day delivery if you work alone. A clear window saves you texts and keeps buyers happy.
Ask for the buyer’s name, phone, pickup day, and number of jars. Put the same fields on every order so you do not miss a detail. A simple text message can confirm the pickup time.
What mistakes cost you money?
The first mistake is pricing from flour alone. The jar, lid, label, and your minutes can cost more than the starter inside. The second is forgetting the monthly fee. $20 a month sounds small until you sell four jars. At four jars, that fee is $5 a jar.
The third is copying a loaf price. Our guide to sourdough loaf prices lists $10 to $18 a loaf. A jar is not a loaf, so use that range as a check on your market, not as your cost. The fourth is selling without an order record. You need to know what you sold, when, and to whom.
How do you make the first sale repeat?
A starter buyer can come back for another jar or for bread. Put a small card in the bag with the date you fed it and a simple way to ask a question. Keep a list of buyers and what they bought. Then send a short note when a fresh batch is ready.
Do not wait for a big launch. Sell to the people who already ask you for starter. Ask them what size they want and when they will pick it up. Then make the next batch to match those orders.
Pick two days a week for feeding and filling. Then you can tell buyers when the next batch is ready. A regular schedule is easier to keep than a rush order.

Common questions
Can I sell a starter if I only make it at home?
Check the cottage food rules for your state. They decide what you may sell from home and what the label must say. Read them before you take money. Our legal guide covers permits and labels, but your state agency has the final word.
Should I sell fresh or dehydrated starter?
Pick the one you can make safely and repeat. Fresh starter goes in a jar with a lid and a label. Dehydrated starter has its own jar and label needs. Each has its own cost base. Our fresh and dehydrated guides show what to count for each.
How do I split the monthly fee across jars?
Take your flat monthly cost and divide it by the number of jars you expect to sell. If you pay $20 a month and sell 20 jars, the fee is $1 a jar. If you sell four jars, it is $5 a jar. Use your real number, not your best month.
What if my price is higher than other sellers?
Check what your price includes. A jar with a label, a card, and a clear pickup time can be worth more than a bare jar. Do not cut your pay to match a price you cannot see. Ask what the other seller includes before you change yours.
Do I need a website to sell starter?
You need a way for buyers to order and pay, not a big website. Brevl gives you a shop with your photos, colors, and your own web address. It works on a phone and a computer. You can start with a 30 day free trial and no card.
How long should I track costs?
Track every batch for at least one month. Then you can see your real jar count, your real flour use, and your real time. A month also covers the Brevl free trial. At the end, keep the numbers that still apply and fix the ones that changed.
