Making cold brew at home is cheaper per ounce if you only count the cost of beans and water — roughly $0.67 to $1.00 per cup versus $4 to $7 at a coffee shop. But when you factor in equipment, time, waste from bad batches, and the inconsistency of homemade results, the gap narrows significantly. Ready-to-drink options like a Bare Brew subscription ($4.50 per can for a 12-pack) land somewhere in between — more than homemade ingredients, but less than most cafés and with zero prep time. Shipping is $8.99 flat on every order — no minimums.
Here’s the full math so you can decide what makes sense for your budget and lifestyle.
The Real Cost of Making Cold Brew at Home
Let’s break down a typical homemade batch using a 1:8 ratio (1 cup of grounds to 8 cups of water):
Per-Batch Ingredients
- Coffee beans: 1 cup of coarsely ground coffee is approximately 4 oz (113g). A 12oz bag of quality beans costs $12–$18. That gives you about 3 batches per bag, or $4–$6 per batch.
- Water: 8 cups of filtered water. Cost is negligible — roughly $0.02.
- Per batch yield: About 6 servings (12oz each) after straining (you lose some water to the grounds).
Per-cup ingredient cost: $0.67–$1.00
That’s genuinely cheap. No argument there.
One-Time Equipment Costs
- Mason jars or pitcher: $5–$15
- Fine-mesh strainer + cheesecloth: $8–$12
- Coffee grinder (if grinding fresh): $25–$60
- Dedicated cold brew maker (Toddy, Hario, etc.): $25–$40
Total startup: $38–$127 depending on what you already own. If you’ve got a French press, you might only need beans.
The Cost of Buying Cold Brew
Coffee Shop Cold Brew
A 16oz cold brew from Starbucks, Dunkin’, or your local café runs $4.50–$6.50. Specialty shops charge up to $7. If you’re buying 5 days a week, that’s $90–$130 per month — or roughly $1,100–$1,560 per year.
Nobody is arguing that coffee shop cold brew is a good deal. It’s convenient, but it’s the most expensive option by far.
Grocery Store RTD Cold Brew
Pre-made cold brew from brands like Stōk, Chameleon, or Califia runs about $4–$6 per bottle (32oz multi-serve) or $2.50–$4.00 per single-serve can/bottle. Monthly cost for daily drinking: $75–$120.
Direct-to-Consumer Cold Brew (Like Bare Brew)
A Bare Brew 12-pack is $53.99, which works out to $4.50 per 12oz can. That’s 320mg of caffeine per can — roughly the equivalent of 3–4 cups of regular coffee. If you’re replacing your daily coffee shop run, a 12-pack lasts nearly two weeks at one can per day, putting monthly cost around $108 before shipping. Shipping is a flat $8.99 per order with no minimum and no free-shipping threshold, so a monthly two-pack order lands near $126 delivered.
At $4.50 per can and 320mg, that works out to about 1.4¢ per milligram of caffeine ($1.41 per 100mg). The subscription option saves an additional percentage off each order.
The Hidden Costs Nobody Talks About
Ingredient cost is only part of the equation. Here’s what the “it’s so cheap to make at home” crowd tends to leave out:
Time
Cold brew takes 12–24 hours to steep. That means you’re always planning a day ahead. The actual hands-on time is about 10–15 minutes per batch (grinding, mixing, straining, cleanup), but the planning overhead is real. Over a month of making 5 batches, that’s roughly 60–75 minutes of active prep time plus the mental load of never running out.
Waste
Bad batches happen. Too fine a grind, too long a steep, beans that were past their prime — and you’ve wasted $4–$6 in beans plus a day of waiting. We don’t have survey data on how often home brewers toss a batch, so we won’t put a number on it — but every discarded batch adds to your real per-cup cost.
Inconsistency
Every batch at home tastes slightly different. Grind uniformity, water temperature, steep time precision, and bean freshness all vary. Some people enjoy the experimentation. Others just want their coffee to taste the same every morning.
Shelf Life
Homemade cold brew lasts 7–10 days in the fridge. If you don’t finish a batch in time, that’s wasted coffee and wasted money. A shelf-stable can, by contrast, is good for 12 months unopened. For more on that, see our guide to cold brew storage.
Side-by-Side: The Cost Comparison
| Option | Cost Per Serving | Monthly Cost (Daily) | Prep Time | Consistency |
|---|---|---|---|---|
| Homemade (ingredients only) | $0.67–$1.00 | $20–$30 | 10–15 min/batch + 12–24hr wait | Variable |
| Coffee shop | $4.50–$7.00 | $90–$140 | Trip to shop | High |
| Grocery RTD | $2.50–$4.00 | $75–$120 | None | High |
| Bare Brew (12-pack) | $4.50 + $8.99 flat shipping per order | ~$108 + shipping | None | Exact same every time |
The Verdict: It Depends on What You Value
If saving every dollar is the priority and you enjoy the ritual of brewing, making cold brew at home is hard to beat on pure cost. You’re looking at $20–$30 per month for daily cold brew — nothing in the market comes close.
But if your time is worth something, if you want consistent results, or if you’ve ever poured a bad batch down the drain on a Monday morning — the convenience premium starts to make more sense. You’re not just paying for coffee; you’re paying to skip the 12–24 hour wait, the cleanup, and the guesswork.
Coffee shops are the worst deal financially. Grocery store RTD splits the difference. And options like Bare Brew — with 320mg of clean caffeine, 0g sugar, 20 calories, and just two ingredients — give you the quality of a homemade batch and the convenience of a coffee shop run for roughly $4.50 a day plus $8.99 flat shipping per order.
Most cold brew drinkers end up with some combination: homemade on weekends when they have time, ready-to-drink during the week when they don’t. The cheapest coffee is always the one you actually drink.
Frequently Asked Questions
How much does it cost to make cold brew per gallon?
A gallon of homemade cold brew costs approximately $6–$10 in coffee beans, depending on bean quality. This yields about 10–11 twelve-ounce servings. Premium single-origin beans push costs closer to $12–$15 per gallon.
Is cold brew concentrate more cost-effective than ready-to-drink?
Yes. A 1:4 concentrate uses more coffee per batch but yields twice as many servings when diluted. Per-serving cost drops to roughly $0.35–$0.50. The tradeoff is you need to dilute every time you pour a glass, and getting the right dilution ratio is another variable.
Does a cold brew subscription save money vs. buying packs individually?
Subscriptions generally lower your per-order cost. On a Bare Brew subscription, the per-can price drops and you never run out. Shipping stays at $8.99 flat on subscription orders too. Check the current subscription terms on the product page for the exact discount.
Why is cold brew more expensive than regular coffee at coffee shops?
Cold brew uses 2–3x more coffee grounds per serving than hot drip, and takes 12–24 hours to make instead of 5 minutes. The higher ingredient cost and longer production time get passed to the customer. It’s also positioned as a premium product — shops know cold brew drinkers are willing to pay more for the smoother taste.
