Coffee Cost Per Cup Calculator

Across the 376 coffees in our catalog with listed bag pricing, the average price is $2.02 per ounce — about $1.28 per cup at a standard 18g dose. Budget picks run as low as $0.48/cup; rare micro-lots and Gesha can run past $9/cup.

18 grams per 12 fl oz cup is the most common specialty-coffee starting point (roughly a 1:16 ratio), though it ranges from about 10g for a light single-serve drip cup to 20-25g for a strong pour over or French press mug. Use our Brew Ratio Calculator to dial in the exact dose for your method.

Almost always, by a wide margin. At the catalog average of $1.28 per cup, brewing at home costs roughly a quarter to a fifth of a $4-6 café drip coffee or latte, even before the cafe's added milk, cup, and labor costs. Two cups a day at home runs about $2.56/day versus $8-12/day buying out.

Usually, but not always — many roasters price larger bags at a modest per-ounce discount, but some rare or limited-lot coffees hold the same per-ounce price regardless of size. Always compare the price-per-ounce (shown above) rather than assuming the bigger bag is automatically the better deal.

Cost per cup = (bag price ÷ bag weight in grams) × grams of coffee used per cup. For example, a $20 12oz (340g) bag at an 18g dose costs $20 ÷ 340 × 18 = $1.06 per cup. The same math works in reverse to find how many cups a bag makes: bag weight ÷ dose per cup.

Dial in your dose precisely instead of eyeballing it — overdosing by even 2-3g per cup adds up fast over a bag. Buying a larger bag size (if your roaster offers a per-ounce discount) and brewing methods that use less coffee per cup also lower cost.
