A flower CSA usually prices for a 45–60% margin — high enough to absorb a bad bloom week, low enough that members renew.
Pricing is step one. Stemwise turns your CSA into a weekly plan: it counts the stems your shares need, checks them against what's blooming, and tells you the surplus to fill bouquets from — and the shortfall to buy in. That's the part the spreadsheet can't do.

Become a founding grower →A flower CSA — community-supported agriculture for bouquets — is one of the best cash-flow tools a small flower farm has: members pay up front, you get working capital in spring, and you have guaranteed homes for your blooms all season. But most growers price it by gut feel, and gut feel almost always runs too low. This calculator works the way a profitable farm actually prices: from the cost of a single bouquet up.
Start with your stems per bouquet and cost per stem (not the wholesale price — your real cost to grow and cut it), add packaging and the labor to build and pack each share, then apply the margin you need to stay in business. The result is a defensible per-share price and a full-season subscription number you can put on a sign-up page today.
| Input | Typical small-farm range |
|---|---|
| Stems per bouquet | 15–25 |
| Cost per stem (grown) | $0.25–$0.50 |
| Packaging per share | $0.40–$1.00 |
| Build + handling time | 4–8 min/share |
| Target margin | 45–60% |
It's tempting to plug in the wholesale price you'd pay for a stem. Don't — that's a buy-in price, not a grow cost. Your real cost per stem is seed and plugs, amendments and drip, and a fair share of your own time spent sowing, pinching, netting, and harvesting, divided across the stems a bed actually yields. Most growers land between $0.25 and $0.50 per stem once labor is counted honestly. If you skip your labor here, your CSA will look profitable on paper and exhaust you in real life.
Both. Quote the per-week price so members can compare it to a grocery-store bouquet (you'll win — yours is fresher and local), and sell the full-season share as one up-front payment so you get the cash when you need it most: spring, when you're buying seed and soil. A half-share (every other week) at a slightly higher per-bouquet price is the easiest way to widen your audience without dropping your margin.
Pricing is the easy half. The hard half is the question this calculator can't answer: will your field actually have 30 bouquets' worth of the right flowers, every week, for 16 weeks? That's a bloom-succession and reconciliation problem — and it's exactly what Stemwise does: it lines up your CSA's weekly stem demand against what you're projected to cut, so you know in advance which weeks are tight and what to buy in.

For a full market-size bouquet (18–25 stems), most farms land between $25 and $40 per week once a 45–60% margin is applied. Smaller "petite" shares run $18–$28. Use the calculator above with your real costs to find your number.
Most run 8–18 weeks, matched to your reliable bloom window — often early summer through first frost. A shorter, fuller season beats a long one with thin shoulder weeks.
Yes — the up-front payment is the main reason to run a CSA. It funds your spring inputs. Offer a small early-bird discount (5–10%) to drive sign-ups before you've spent on seed.
45–60%. Below that, one hailstorm or pest week erases your profit; above it, you risk pricing out the neighbors who are your most loyal members.
