What is the Coffee Spending Calculator?
This calculator reveals the real cost of your coffee habit. A daily latte feels harmless, but small amounts add up fast over a year. Enter how many cups you drink per day and the average price per cup, and instantly see your daily, monthly and yearly coffee spend.
How to use it
Enter your typical number of cups per day (you can use decimals like 1.5 if it varies), then the average price you pay per cup. Include both home-brewed and café cups for an honest picture. The result shows three figures so you can decide whether to keep the habit or cut back.
The formula explained
The core calculation is simple multiplication:
Daily = cups per day × price per cup. Multiply daily spend by 365 for the yearly total, and by 30.4375 (the average days in a month) for the monthly total. Using 30.4375 rather than 30 keeps the monthly and yearly figures consistent.
$$\begin{gathered} \text{Daily} = \text{Cups/day} \times \text{Price/cup (\$)} \\[1.5em] \text{Monthly} = \text{Daily} \times 30.4375 \qquad \text{Yearly} = \text{Daily} \times 365 \end{gathered}$$
Worked example
Suppose you buy 2 cups a day at $4.50 each. Daily spend is \(2 \times \$4.50 = \$9.00\). Over a year that's \(\$9.00 \times 365 = \$3{,}285\). Monthly that's \(\$9.00 \times 30.4375 \approx \$273.94\). Switching one of those cups to home-brewed coffee could save well over $1,000 a year.
FAQ
Should I include weekends? Yes — the calculator assumes you drink coffee every day. If you only drink on workdays, lower your cups-per-day figure (e.g. 5/7 of your weekday amount).
Why 30.4375 days per month? That's \(365 \div 12\), the true average month length, so monthly \(\times 12\) equals the yearly figure.
Does this account for inflation or price changes? No, it uses today's price for a full year. For rough planning that's fine; revisit it if prices rise.
