Small Farm Stand CSA Box Price Calculator

Work out what to charge for each CSA box so the box pays for itself. Enter the produce cost, packaging and delivery cost per box, how many boxes you pack each week and the profit margin you want, then see the price per box, weekly revenue and weekly profit.

Formula: price per box = cost per box / (1 - target profit margin), where cost per box = produce cost + packaging cost + delivery cost, and weekly profit = (price per box - cost per box) x boxes per week - market fee per week.

How to Use the Small Farm Stand CSA Box Price Calculator

This calculator prices one weekly CSA box from your real costs, so you do not have to guess or copy another farm price.

Enter the produce cost per box, which is what the food inside one box costs you to grow or buy in.
Enter the packaging cost per box, for the box, bags, labels and ice packs.
Enter the delivery cost per box, for fuel and driving time, or enter 0 if members collect the box.
Enter how many boxes you pack each week, then enter the target profit margin as a percent.
Enter the market fee per week if you pay one, or leave it at 0, then press Calculate or press Enter.

Press Calculate to see the price per box first, with the weekly totals below it.

The CSA Box Price Formula

Cost per box = produce cost + packaging cost + delivery cost. Price per box = cost per box / (1 - target profit margin). Weekly revenue = price per box x boxes per week. Weekly profit = (price per box - cost per box) x boxes per week - market fee per week. The margin is a share of the selling price, not a share of the cost, which is why the formula divides by (1 - margin) instead of multiplying by (1 + margin).

Produce cost is the value of the food in one box, packaging cost covers the box and packing materials, delivery cost covers transport for one box, and the market fee is any fixed weekly fee for the stall or market. Our food truck menu pricing calculator uses the same margin math to price a menu item from its food cost, and our small bakery ingredient cost calculator works out the ingredient cost of one batch in the same way.

Worked Example: A $23.50 Box Priced at $31.33

A small farm packs 40 boxes a week with produce at $18 per box, packaging at $2.50 and delivery at $3. The target margin is 25% and there is no market fee.

Cost per box: $18 + $2.50 + $3 = $23.50.
Price per box: $23.50 / (1 - 0.25) = $23.50 / 0.75 = $31.33.
Profit per box: $31.33 - $23.50 = $7.83.
Weekly revenue: $31.33 x 40 boxes = $1,253.20.
Weekly profit: $7.83 x 40 boxes - $0 = $313.20.

Check the margin. Profit per box divided by price per box is $7.83 / $31.33, which is 25%, so the price hits the target exactly. As a second check, take a $15.50 box with produce $12, packaging $1.50 and delivery $2, packed 25 times a week at a 20% margin and no market fee. The price is $15.50 / 0.80 = $19.38, weekly revenue is $19.38 x 25 = $484.50 and weekly profit is ($19.38 - $15.50) x 25 = $97. The same steps work for any box, so try your own numbers in the tool above.

What Changes Your CSA Box Price

The produce cost moves the price the most, because it is the biggest part of the $23.50 cost in the worked example. A $2 rise in produce cost lifts the cost per box to $25.50 and the price to $34 at the same 25% margin. Packaging and delivery matter in the same way, so a delivered box costs more than a collected box.

The margin moves the price faster than most growers expect. At the same $23.50 cost, a 10% margin gives a price of $26.11, a 20% margin gives $29.38, a 25% margin gives $31.33, a 30% margin gives $33.57 and a 40% margin gives $39.17. The box count does not change the price per box, but it changes the weekly totals a lot. At 20 boxes a week the worked example earns $156.60 in weekly profit, and at 60 boxes it earns $469.80, with the same $31.33 price. A market fee comes straight off the profit, so a $50 weekly fee cuts the worked example profit from $313.20 to $263.20.

Margin or Markup: Do Not Mix Them Up

Margin and markup sound alike, but they are measured from different numbers. Margin is profit as a share of the selling price, while markup is profit as a share of the cost. A 25% markup on the $23.50 cost gives a price of $23.50 x 1.25 = $29.38, and the margin on that price is only ($29.38 - $23.50) / $29.38, which is 20%, not 25%. To earn a true 25% margin you need a 33.3% markup, because $23.50 x 1.3333 = $31.33.

Farm pricing guides often quote higher margins for CSA sales than the 25% in the worked example. SmartFarmPilot lists a 40 to 60% target margin for CSA, and a flower CSA calculator from Stemwise quotes 45 to 60%. At 40% the same $23.50 box would cost $39.17. The right margin depends on what your $18 produce cost already includes. If it includes your labor at a fair hourly rate, 25% can be enough. If it leaves your labor out, aim higher, because unpaid labor is the cost most small farms miss. Test a few margins in the calculator before you commit.

Before You Set Your CSA Box Price

Compare your answer with real box prices near you before you print it. Published CSA price lists show full shares commonly running $15 to $35 a week, so a $31.33 box sits near the top of that range and needs a full, varied box to feel fair to members. Tell members what is in the box each week, and be honest that the contents change with the season.

Price the whole season too. At 40 boxes a week for a 20 week season, the worked example brings in $25,064 in revenue and $6,264 in profit, before costs the calculator does not cover, such as seed, card fees and tax. Rework the numbers each season. Our catering cost per person calculator prices a different kind of per guest food cost the same way, and our coffee shop menu pricing calculator shows how the same margin math prices a drink. Review the price when any cost changes by more than a dollar a box.

Frequently asked questions

How much should I charge for a CSA box?

Charge the price that covers your cost per box at the margin you want. In the worked example, a box that costs $23.50 to fill sells for $31.33 at a 25% margin. Published CSA price lists show full shares commonly running $15 to $35 a week, so check local farm prices too, and do not copy them without checking your own costs first.

What is a good profit margin for a CSA box?

A 20 to 30% margin is a common starting point for a weekly vegetable box, and the worked example uses 25%. Farm pricing guides often quote 40 to 60% for CSA sales, but that only works if your costs include your labor. At 40% the same $23.50 box would cost $39.17, so test a few margins in the calculator and pick one your members will pay.

How do I work out the produce cost per box?

Add up what the food in one box costs you, item by item, at the price you would pay to grow it or buy it in. In the worked example the produce costs $18 per box. Include seed, water and harvest labor in that number, or the price will look profitable on paper and lose money in real life.

Should delivery be in the box price or charged separately?

Either way works, as long as you only count it once. This calculator folds delivery into the box price, so enter your delivery cost per box and the price covers it. If you charge delivery separately, enter 0 for delivery cost and add the delivery charge on top of the price the calculator gives you.

What if the market fee eats my profit?

A weekly market fee comes straight off your weekly profit. In the worked example a $50 weekly fee cuts the profit from $313.20 to $263.20 on 40 boxes. If the fee leaves too little profit, raise the box count, raise the margin or move to a pickup point with no fee.

How many boxes do I need to sell to make $500 a week in profit?

Divide the profit you want by the profit per box. In the worked example the profit is $7.83 per box, so $500 / $7.83 is 63.9, which means 64 boxes a week. At 64 boxes the weekly profit is $501.12 with no market fee.

This is an estimate for planning. Actual prices depend on your costs, market and customers.
