Is Homemade Coconut Yogurt Actually Cheaper?
Dairy-free coconut yogurt has exploded in popularity, but a single 5.3 oz cup at the grocery store often runs $2 to $3.50 — and a larger 24 oz container can top $8. Making your own at home with full-fat coconut milk, probiotic capsules, and a touch of starch can dramatically cut that per-serving cost, but only if you run the numbers first.
This calculator breaks down exactly what each homemade cup costs you, comparing it directly to what you'd spend on store-bought brands like So Delicious, Cocoyo, or Harmless Harvest. The key variables are the price of canned coconut milk in your area, the cost per probiotic capsule from your preferred brand, and whatever thickener you use — tapioca starch, agar-agar, or arrowroot powder.
How the Yield Estimate Works
A standard 13.5 oz can of full-fat coconut milk yields approximately 1.5 cups of finished yogurt after culturing and any slight thickening. This accounts for minor evaporation and the fact that the yogurt firms up as it chills. If you strain your yogurt through a cheesecloth to make a thicker "Greek-style" version, your yield will be lower — roughly 1 cup per can — but the flavor and texture intensify significantly.
Where the Real Savings Hide
The biggest lever is coconut milk price. Buying canned coconut milk in bulk (a case of 12 to 24 cans) from a warehouse club or online retailer can reduce your per-can cost by 30–50% compared to buying individually at a natural grocery store. Probiotic capsules vary widely — a budget bottle of 60 capsules for $15 gives you a cost of about $0.25 per capsule, while premium brands can run $1 or more each. Most batches require only 2 capsules, so this line item is usually small.
Hidden Costs Worth Noting
The calculator focuses on ingredient costs, which are the most significant variable. You'll also invest 5–10 minutes of active prep time and 12–24 hours of hands-off incubation time (in an oven with the light on, an Instant Pot, or a dedicated yogurt maker). A yogurt maker costs $20–$40 as a one-time purchase, amortized quickly if you make yogurt weekly. Electricity for incubation adds pennies per batch.
