Coffee Cost Calculator
Calculate your annual coffee habit spending across daily cafe lattes and home brewing, and project 5-year and 10-year wealth opportunity costs.
Annual Coffee Habit & Wealth Opportunity Formula
Annual Spend = (Cafe Cups × Price × 52) + (Home Cups × Cost/Cup × 52); 10-Year FV = Monthly Savings × [((1 + r)^120 − 1) / r]- Cafe Drink Benchmark: Commercial lattes and cold brews average $5.00 to $6.50 including tax and tip.
- Home Brewing Cost: Specialty 12 oz bean bag ($15.00 / 24 cups = $0.62) + milk/syrup ($0.35) = ~$0.97 per cup.
- Compound Opportunity: Future value of monthly coffee savings invested in an S&P 500 index fund at 7% return.
