Coffee Bean Annual Cost Calculator
Calculate yearly coffee bean cost from cups per day, grams per cup, and price per pound.
Compare grocery beans to specialty roasters.
The annual coffee bean cost depends on three numbers: cups per day, grams per cup, and price per pound.
The math is plain multiplication, but the inputs are the surprising part for most people.
annual_cost = cups_per_day × grams_per_cup × 365 × (price_per_lb / 453.6)
Standard brew ratios by method (grams of coffee per cup):
- Drip / pour-over: 60-70 g per liter, so 12-14 g per 6-oz cup
- French press: 60 g per liter, similar
- Espresso single shot: 7-9 g
- Espresso double shot: 16-20 g (this is what most “lattes” use)
- Aeropress: 10-15 g per 200-ml cup
- Cold brew: 100 g per liter (much stronger ratio because dilution follows)
Bean prices per pound, retail:
- Grocery store standard (Folgers, Maxwell House): $5-8/lb
- Trader Joe’s whole bean: $7-10/lb
- Costco Kirkland: $5-7/lb (often a great deal on a quality roast)
- Starbucks bagged: $11-14/lb
- Specialty roaster (Counter Culture, Stumptown): $18-25/lb
- Direct trade premium (Onyx, Heart): $24-35/lb
A worked example.
2 drip cups per day, 14 g each, $14/lb specialty beans.
Annual coffee weight: 2 × 14 × 365 = 10,220 g = 22.5 lb.
Annual cost: 22.5 × 14 = $315.
Same consumption with $7/lb grocery beans: $158.
The price gap looks larger than it really is when you think about it as cost per cup: 24 cents per cup specialty vs 12 cents per cup grocery.
Both are dramatically less than a $4 cafe drip coffee.
Espresso drinkers consume more grams per drink but typically fewer drinks per day.
A daily double-shot latte uses 18 g, so 6,570 g/year = 14.5 lb.
At $20/lb specialty espresso beans, that is $290/year — about the same as drip drinkers spend, despite drinking less coffee.
A practical note on freshness.
Beans peak in flavor 5-21 days after roasting and fall off quickly after 60 days.
Buying a 5 lb bag from Costco is great for cost per pound but you will probably drink the last pound past the point where the beans are fresh.
Most heavy coffee drinkers settle on 1 lb bags every 2-4 weeks from a local roaster — the cost premium is 30-50% over Costco, but the cup quality is meaningfully better.
A subtle math gotcha.
The “12-cup” pot on most coffee makers uses 5-oz cups, not 8-oz cups.
A 12-cup pot is actually 60 oz of brewed coffee, or about 1.7 liters.
At the standard 60 g/L ratio, that is 100 g of beans per pot — much more than people realize, and much closer to “8 mugs of coffee” than “12 cups.”
