What to remember
- Cost the whole batch, not just the flour.
- Add starter feed, packaging, and oven energy.

- Check the margin after all three costs.
The number you want is your cost per loaf, not the price on a bakery shelf. This guide shows how to find how much does homemade sourdough cost for your own kitchen, then how to turn that number into a price you can defend at a market table.

What goes into the cost of a sourdough loaf
A sourdough loaf carries five costs: ingredients, starter feed, packaging, oven energy, and your time. Your monthly shop cost sits on top of those. Flour is only one line. Your hands and your oven also set the real cost.
Starter feed is easy to miss because you buy the flour weeks before you bake. Packaging is easy to miss because a bag feels small next to a loaf. Both belong in the batch cost.
How to cost starter feed and oven energy
Starter feed is a real ingredient cost, even when you buy the flour weeks before you bake. Weigh the flour and water you use to feed the starter, cost that amount, and divide it across the loaves that starter makes. A small feed every day adds up over a month, so put it in your batch cost.
Oven energy is a batch cost, and you can find it from your utility bill. Use your rate and your bake time to apply a power cost to the batch. If you do not have a meter, use the bill and the same guide to spread that cost across the loaves.
Cost one batch step by step
Pick one batch size and cost it from start to finish. Do the same math for every loaf you sell so your price does not drift. The steps below work for a two loaf bake or a ten loaf bake.
List every ingredient in one batch
Write down flour, water, salt, starter feed, and anything you put in the dough. Use the amount you actually weigh, not a guess.
Add packaging and energy
Count bags, labels, boxes, and the power your oven uses. These are easy to forget and they change the cost per loaf.
Put a value on your time
Track the hands-on minutes for mixing, shaping, scoring, and packing. Multiply by an hourly rate you would pay someone else.
Spread your monthly shop cost
Add your flat monthly costs, such as your Brevl shop at $20 a month, and divide by the loaves you sell in that month.
Divide by loaves and check margin
Add ingredients, packaging, energy, labor, and overhead. Divide by the number of loaves. Subtract that cost from your price to see your margin.
If you bake once a week, cost one week at a time. If you bake once a month, cost the whole month. The math is the same. The number you want is cost per loaf, not cost per bake.
A worked example with your own numbers
The example below uses round numbers to show the math. Replace them with your receipts and your hourly rate.
Say one batch makes two loaves. Your flour, starter feed, salt, packaging, and oven energy come to $5 for the batch, so ingredients, packaging, and oven energy are $2.50 a loaf. You track 30 minutes of hands-on work per loaf and pay yourself $15 an hour, so labor is $7.50 a loaf.
Your Brevl shop is $20 a month and you sell 40 loaves, so overhead is $0.50 a loaf. Your total cost is $10.50 a loaf. At $14 a loaf, your margin after ingredients, labor, and overhead is $3.50 a loaf, or $140 on 40 loaves.
If you sell 20 loaves instead of 40, the same $20 shop cost is $1 a loaf, not $0.50. Your margin at $14 drops to $3 a loaf. That is why volume matters before you cut your price.
Write the example on the same page as your recipe. When flour or packaging changes, change the number. A price built on an old cost is a guess.
What changes your cost per loaf the most
Labor is the line that moves most when your batch size changes. Mixing and shaping take hands-on minutes for each loaf, so track those minutes instead of guessing. Packaging and starter feed are small lines that add up over a month. Check all three before you set a price.
Volume changes your overhead per loaf more than any ingredient price. A flat $20 shop cost spread over 10 loaves is $2 a loaf, while 40 loaves makes it $0.50. Price for the volume you actually sell, not the volume you hope for.
Where home bakers lose money on sourdough
The first mistake is not paying yourself. The second is spreading a monthly shop cost over too few loaves. The third is forgetting the small buys: bags, labels, twine, and the flour you feed your starter. Add them to the batch before you set a price.
Do not set a price from a competitor’s menu. Their rent, labor, and volume are not yours. Use their price as a check, not as your cost.
How to set a loaf price after you know the cost
Start with your cost per loaf. Add the margin you want, then check that price against what your market already pays. If the price is too high for your buyers, shrink the loaf or cut a cost before you cut your own pay. Link to what baking costs each month to see the monthly side.
A simple check is to divide your price by your cost. If the price is $14 and the cost is $10.50, the price is 1.33 times the cost. That leaves a thin margin. Aim for a gap that pays you for the risk and the selling time.
What to check before you sell your first loaf
Check your state cottage food rules and your county health department before you take money. Keep your cost records separate from your personal money. Link to how much a homemade pie costs if you plan to sell a second item next to bread.
How to track cost after each bake
Keep a simple sheet for each bake: date, loaves, ingredient cost, packaging cost, hours, and price. After four bakes you will see your real average. That average is the number you use for the next market.
Add a column for starter feed and oven energy so the sheet matches your batch math. Review the sheet when flour or packaging changes. A price built on an old cost is a guess.
Common questions
Does homemade sourdough cost less than store bread?
It can, but only if you count your time as free. Flour and energy are small. Your hands-on time, starter feed, and packaging are the bigger costs. Compare your full cost per loaf to the price you would pay, not just the flour bag.
How do I cost starter feed?
Treat starter feed as an ingredient. Weigh the flour and water you use to feed it, cost that amount, and divide it across the loaves that starter makes. A small feed every day adds up over a month, so put it in your batch cost.
Should I include my oven cost?
Yes. Add the energy your oven uses for a bake. If you do not have a meter, use your utility bill to find your rate and apply it to your bake time. The same guide can show you how to spread that cost across a batch.
What if I sell only a few loaves a month?
Your overhead per loaf is higher when you sell fewer loaves. A flat $20 a month shop cost spread over 10 loaves is $2 a loaf. Spread over 40 loaves, it is $0.50. Price for the volume you actually sell.
Do I need a business license to sell sourdough?
That depends on your state and your local rules. This guide does not give legal advice. Check your state cottage food rules and your county health department before you sell your first loaf. Keep your cost records separate from your personal money.
