A daily coffee habit feels small — $5 a day — but adds up to over $18,000 over a decade. This calculator makes the lifetime cost visible and lets you compare buying vs. brewing at home.

Formula
Daily Cost = Cups per Day × Cost per Cup
Annual Cost = Daily Cost × 365
Total Cost = Annual Cost × Years
How it works
The calculator multiplies daily cup count by price per cup to get a daily spend, then scales that to an annual and a multi-year total by assuming 365 coffee days per year. A cumulative area chart shows how spend compounds year over year up to a 50-year maximum. Seasonal variations, price changes, and investment opportunity cost are not included.
Worked example
- Daily cost = 2 cups × $5.00 = $10.00.
- Annual cost = $10.00 × 365 = $3,650.
- Total over 10 years = $3,650 × 10 = $36,500.
Daily spend: $10.00; Annual spend: $3,650; Total over 10 years: $36,500
Common mistakes to avoid
- Using only the sticker price of a coffee without including tips, which add 15-20% to the real per-cup cost at most cafes.
- Comparing cafe cost to home-brewing cost without accounting for the full cost of home equipment amortized over its lifespan.
- Underestimating the opportunity cost of invested savings — $5 a day in an index fund over 10 years is worth substantially more than the simple sum.
Key terms
- Daily spend
- The total amount spent on coffee in a single day (cups per day multiplied by price per cup).
- Opportunity cost
- The potential return foregone by spending money rather than investing it. Not calculated here but often cited in latte-factor analyses.
- Latte factor
- A personal-finance concept popularised by David Bach describing how small daily purchases compound into large sums over time.
- Cumulative spend
- The running total of all money spent on a habit from year 1 up to a chosen year, shown in the area chart.
- Cost per cup
- The all-in price of one serving, including the beverage price, tip, and any extras such as syrup or milk alternatives.
Frequently asked questions
- What if I make coffee at home instead?
- Home-brewed coffee typically costs $0.20–$0.50 per cup versus $3–$7 at a café. Enter the home cost to see how much you'd save over the same period.
- Does this account for inflation?
- No — the calculator uses today's price for simplicity. Prices tend to rise over time so the real total may be higher.
