Home Coffee vs Coffee Shop: The Real Cost per Cup
Share
A fresh bag of specialty coffee can look expensive next to a supermarket can, and a café latte can feel like a small treat rather than a real cost. Neither impression tells you much. The useful number is the cost of coffee per cup, and you can calculate it in under a minute.
Here is the short answer from our worked examples: brewing a 10 oz mug of fresh-roasted specialty coffee at home costs roughly $0.73 to $1.25, depending on bag size, and a homemade latte about $1.03 to $1.59. If your café charges $3.00 for drip coffee and $5.50 for a latte, a daily habit adds up to a difference of about $640 to $1,630 a year. Your numbers will differ, so below you will find the formula, every assumption, and how to plug in your own prices.
Key takeaways
- Cost per cup = (bag price ÷ grams in the bag) × grams per cup + extras (milk, filter, energy).
- The dose matters as much as the price: a 16.5 g mug from a 12 oz bag gives about 20 cups.
- Bigger bags lower the cost per gram, but only if you can finish them while the coffee is still fresh.
- With our example prices, a $150 drip setup pays for itself in about 86 days of daily coffee, and a $500 espresso setup in about 128 days of daily lattes.

The cost per cup formula
Every cost per cup calculation comes down to three steps:
- Price per gram = bag price ÷ weight of the bag in grams.
- Coffee cost per cup = price per gram × grams of coffee you use per cup.
- Total cost per cup = coffee cost + extras (milk, sugar, filters, electricity).
Use grams, not ounces or scoops. A 12 oz bag weighs 340.2 g (1 oz = 28.35 g), a 1 lb bag 453.6 g, a 2 lb bag 907.2 g and a 5 lb bag 2,268 g. Scoops vary with grind and roast, while grams do not.
Worked example
Take a 12 oz bag at $24.99 and a 16.5 g dose:
- Price per gram: $24.99 ÷ 340.2 g = $0.0735 per gram
- Coffee per mug: $0.0735 × 16.5 g = $1.21
- Add a paper filter ($0.03) and electricity (under 1 cent): about $1.25 per mug
- Mugs per bag: 340.2 ÷ 16.5 = about 20
Our assumptions (change them freely)
These are example figures to show the method, not claimed national averages for café prices. Swap in your own numbers.
| Item | Assumption | Why |
|---|---|---|
| Coffee prices | Our House Blend at the time of writing: 12 oz $24.99, 1 lb $29.99, 2 lb $49.99, 5 lb $94.99 | Real prices for fresh-roasted specialty coffee; shipping not included |
| Mug of filter coffee | 16.5 g coffee for 300 ml (10 oz) water | 55 g per liter, the Specialty Coffee Association’s reference brew ratio |
| Home latte | Double shot with 18 g coffee + 8 fl oz (237 ml) whole milk | A common double-shot dose |
| Milk | $4.229 per gallon, so $0.26 per 8 oz | US city average for whole milk, August 2026 (BLS data via FRED) |
| Electricity | 0.04 kWh per cup at 18.2 cents per kWh = $0.007 | Heating 300 ml of water takes about 0.027 kWh before losses; 18.2 cents is the EIA 2026 US residential forecast |
| Paper filter | $0.03 | Example price; zero with a French press or metal filter |
| Café prices | Drip coffee $3.00, latte $5.50 | Example prices only; check your own receipts |
Cost per cup by bag size
Same coffee, same dose, different bag sizes. All figures are rounded to the nearest cent.
| Bag | Grams | Price per gram | 10 oz mugs per bag | Drip mug (with filter and energy) | Double shots per bag | Home latte |
|---|---|---|---|---|---|---|
| 12 oz ($24.99) | 340.2 | $0.073 | 20.6 | $1.25 | 18.9 | $1.59 |
| 1 lb ($29.99) | 453.6 | $0.066 | 27.5 | $1.13 | 25.2 | $1.46 |
| 2 lb ($49.99) | 907.2 | $0.055 | 55.0 | $0.95 | 50.4 | $1.26 |
| 5 lb ($94.99) | 2,268.0 | $0.042 | 137.5 | $0.73 | 126.0 | $1.03 |
Notice how fast the price per gram drops with bigger bags: the 5 lb bag costs 43% less per gram than the 12 oz bag. The catch is freshness. A 5 lb bag at two mugs a day lasts about 69 days, which only makes sense for a household or an office that drinks a lot, or if you split it into airtight portions.
What about a stronger cup?
If you like a bolder mug, say 20 g for the same 10 oz, multiply by 20 instead of 16.5. With the 12 oz bag, that is $0.0735 × 20 = $1.47 of coffee, plus filter and energy, about $1.51. Dose is the easiest lever on both taste and cost.
Home vs café: the yearly totals
Now compare one drink a day for a full year (365 days) and for workdays only (260 days).
| Scenario | Home cost per cup | Café price | Saved per cup | Saved per year (365 days) | Saved per year (260 workdays) |
|---|---|---|---|---|---|
| Drip, 12 oz bag | $1.25 | $3.00 | $1.75 | $639 | $455 |
| Drip, 5 lb bag | $0.73 | $3.00 | $2.27 | $829 | $591 |
| Latte, 12 oz bag | $1.59 | $5.50 | $3.91 | $1,426 | $1,016 |
| Latte, 5 lb bag | $1.03 | $5.50 | $4.47 | $1,633 | $1,163 |
Calculated with unrounded values, so a row may differ from its rounded parts by a dollar.
To be fair to cafés, the comparison is not only money. You pay for a skilled barista, a seat, the atmosphere and no washing up. Many people do both: brew at home on weekdays and treat the café visit as a pleasure rather than a routine.
Equipment payback time
Home brewing has a starting cost. The payback formula is simple:
Payback (days) = equipment cost ÷ money saved per drink (for one drink a day)
| Setup (example prices) | Cost | Saved per drink | Payback |
|---|---|---|---|
| Pour-over cone or French press only | $30 | $1.75 (drip vs café) | About 17 days |
| Drip brewer + burr grinder | $150 | $1.75 | About 86 days |
| Entry espresso machine + grinder | $500 | $3.91 (latte vs café) | About 128 days |
All three examples use the 12 oz bag prices. If you make two drinks a day, halve the payback time. If you skip the grinder and buy pre-ground coffee, your starting cost drops, though you trade away some aroma, as our guide on whole bean vs ground coffee explains.
Ways to lower your cost without losing quality
- Weigh your coffee. Scooping by eye often means using more coffee than you need. A cheap kitchen scale pays for itself quickly.
- Match bag size to your speed. Buy the largest bag you can finish while it is still fresh. Two people drinking two mugs each a day will finish a 2 lb bag in about two weeks.
- Brew only what you drink. Coffee left on a hot plate is money poured away.
- Make café drinks at home. Lattes and cappuccinos show the biggest savings, because café prices for milk drinks are high and milk at home is cheap.
- Store it well. An airtight container, away from light and heat, keeps you from throwing out stale coffee.
- Skip the syrup bottles. Flavored beans add vanilla, hazelnut or chocolate aroma without buying separate syrups.

Every bag is roasted 1–5 days before delivery, so even a larger bag starts its life at peak freshness.
Cost of coffee per cup FAQ
How do I calculate the cost of coffee per cup?
Divide the bag price by its weight in grams, then multiply by the grams you use per cup. Add the cost of milk, filters and energy if you want the full picture.
How many cups are in a 12 oz bag of coffee?
About 20 mugs of 10 oz at 16.5 g each, or about 19 double espresso shots at 18 g each. A stronger dose gives fewer cups.
Is it really cheaper to make coffee at home?
In almost every scenario, yes. With our example prices, home drip coffee costs $0.73–$1.25 a mug against $3.00 at a café, and a home latte $1.03–$1.59 against $5.50.
Is buying a 5 lb bag worth it?
Only if you can use it while it is fresh. It cuts the price per gram by more than 40% compared with a 12 oz bag, but a bag that goes stale before you finish it is not a saving.
