Coffee Cost Calculator
Compare daily and annual cost of home brewed coffee versus cafe purchases.
Returns yearly savings and break-even point for buying a home espresso machine.
The “latte factor” — the idea that small daily purchases add up to large annual sums — is one of the most popular personal finance concepts. Here is how to calculate it precisely.
Daily cost formula: Daily Coffee Cost = Number of Cups × Cost per Cup
Annual cost: Annual Cost = Daily Coffee Cost × Days per Year
Home brewing cost: Home Cost per Cup = (Coffee Grounds Cost per 100g ÷ 100) × Grams per Cup + Electricity + Milk
Typical home brew cost: $0.25–$0.75 per cup (including milk and electricity) Typical café purchase: $4.50–$7.00 per specialty drink
Savings from switching to home brew: Daily Savings = Café Cost − Home Brew Cost Annual Savings = Daily Savings × 365
Worked example: You buy a $5.50 latte every workday (250 days/year). Annual café spend = $5.50 × 250 = $1,375/year
Switching to home espresso + milk: Home cost = $0.60/cup × 250 = $150/year Annual savings = $1,375 − $150 = $1,225/year
Over 10 years (invested at 7%): Future value = $1,225 × ((1.07^10 − 1) / 0.07) = $16,930
