How to Use This CSA Pricing Calculator
- Set your season length and target members. Enter the number of delivery weeks and how many full-price versus work-share members you expect to recruit.
- Enter all annual farm costs. Work through each cost category: fixed costs (land, equipment), variable costs (seeds, fuel, labor), your own salary, and marketing. Every cost category has a verified field — don't skip the farmer salary line.
- Add any offsetting income. If you also sell at a farmers market or to restaurants, enter that income to reduce the portion your CSA must cover.
- Review the base (medium) share price. The green results panel on the right shows your minimum season price, weekly equivalent, and full budget breakdown instantly.
- Check tier pricing. The tier table shows how small, large, and custom share prices scale from your base price. Adjust the multipliers to match your local market.
- Review work-share terms. See exactly how much the labor credit reduces the work-share member's price, and what they pay after the discount.

The Cost-Plus Pricing Method Explained
The cost-plus method is the approach recommended by NC State Extension's CSA Guide and Utah State University Extension. The core formula is:
Base share price = (Total annual farm costs − Other farm income) ÷ Total member count
Where total farm costs include fixed costs (land, equipment, insurance, structures), variable costs (seeds, hired labor, fuel, packaging), the farmer's own salary, and marketing/distribution expenses. This ensures the price actually covers what it costs to run the farm — a step many new CSA farmers miss, particularly around including their own pay.
Why Farmer Salary Is the Most Commonly Missed Cost
USU Extension explicitly warns that "many growers underestimate their own worth when determining a budget." Your time has a real market value. If you don't include your salary as a line item before dividing by member count, you are essentially subsidizing your members' food with your own unpaid labor. Use what you'd pay an equally skilled farm manager as a reference point.
Multi-Size Share Tiers
Offering small, medium, and large shares lets you serve different household sizes without complexity. A common approach used by experienced CSA farms is to price the small share at roughly 60–70% of medium (it uses less produce and packaging) and the large at 130–150%. You can calibrate these multipliers based on what your local CSA market will bear.
Work-Share Members: How the Math Works
A work-share membership trades on-farm labor for a discount. The credit is calculated as: hours/week × weeks in season × hourly labor value × discount %. For example, a member working 3 hours/week over a 20-week season at a $15/hr labor value earns a $900 labor credit. If you apply 100% of that credit, they pay the base price minus $900. If you apply 75%, they receive a $675 discount. This calculator shows the exact discounted price so you can explain it clearly to prospective work-share members.
How Other Farm Income Reduces Your CSA Price
If your farm earns money through farmers markets, restaurant wholesale, or other channels, those revenues reduce the share of your annual budget that the CSA alone must cover. Enter your expected annual income from other channels in the "Other Farm Income" section. The calculator subtracts it from your total costs before dividing by your member count, giving you a lower (and more accurate) minimum share price for the CSA.
Frequently Asked Questions
How do I calculate the right price for my CSA share?
Use the cost-plus method: add all annual farm costs (fixed costs like land and equipment, variable costs like seeds and fuel, your own salary, and marketing expenses), then divide by the number of shares you plan to sell. The result is your minimum share price for the season. Divide by delivery weeks to find the weekly equivalent. This method is recommended by NC State Extension and USU Extension for CSA pricing.
Should I include my own salary when pricing CSA shares?
Yes — absolutely. This is the most common pricing mistake new CSA farmers make. NC State Extension specifically notes that your budget should "provide a fair salary for the farmer." USU Extension warns that "many growers underestimate their own worth." Include a reasonable annual salary for yourself as a line item before dividing by member count. If you don't, you're subsidizing your members' produce with unpaid labor.
What is a work-share CSA membership?
A work-share (also called a labor-share) is a membership where the member works a set number of hours per week on the farm in exchange for a discount on their share price. The discount is calculated based on: hours worked × weeks in season × your farm's hourly labor value × discount percentage. This reduces the share cost for the member while supplying the farm with free or subsidized labor. Work-share slots are typically limited to a small number of the total membership.
How does offering tiered share sizes (small/medium/large) affect pricing?
Tiered shares serve different household sizes. Price the medium share at 100% of your calculated base price. A small share typically sits at 60–70% (less produce, less packaging) and a large at 130–150%. Adjust the multipliers to reflect how much more produce (and therefore cost) each tier actually contains, and sanity-check against what local CSAs charge for comparable tiers.
Should other farm income (farmers market, wholesale) reduce my CSA price?
Yes. If your farm earns income from farmers markets, restaurants, or other channels, those revenues reduce the portion of your total farm budget that must be covered by CSA shares. Enter your expected annual income from other channels in this calculator — it subtracts that amount from your total costs before dividing by member count, giving you the true CSA-only minimum share price.
What is the average CSA share price in the US?
Share prices vary widely. NC State Extension cites typical full-season costs ranging from $400–$700 annually. USU Extension data from Utah puts CSA shares at $300–$600. Some longer-season or premium-variety CSAs charge $650–$800+. Always calculate your own cost-plus price first, then compare it against local CSAs. If your calculated price is significantly above local market rates, look for costs to reduce or other income channels to add.
What's the difference between fixed and variable farm costs?
Fixed costs stay the same regardless of how much you grow — land rent or mortgage, equipment depreciation, insurance, and property taxes. Variable (operating) costs change with production volume — seeds, transplants, soil amendments, hired labor, fuel, and packaging. Both must be included in your CSA budget. A common mistake is tracking only the visible variable costs and forgetting the fixed overhead that accumulates every month.
