Overview
Small daily purchases add up. This calculator turns your coffee-shop habit into clear weekly, monthly and yearly numbers, and shows how much you'd save by brewing at home.
It also projects what that yearly saving could become if you invested it instead — the so-called 'latte factor' — a simple way to see the opportunity cost.

That's $1,125 a year on coffee. Brewing at home saves about $1,000 a year, which invested for 10 years at 7% could grow to roughly $13,800.
A daily $4 coffee, every day
Seven coffees a week for 52 weeks at $4.00, $0.40 home cost.
Interpretation
About $1,456 a year. Brewing at home saves roughly $1,310 a year.
Frequently asked questions
Does this mean I should never buy coffee out?
No - it simply makes the cost visible so you can decide. Many people keep buying coffee out but cut the frequency, capturing most of the saving while still enjoying the ritual.
How is the 'if invested' number calculated?
It treats your yearly saving as a recurring annual investment growing at the return you enter, using the standard future-value-of-an-annuity formula. It is illustrative, not a forecast.
What should I put for the home cost?
Add up beans, milk and a little energy per cup. Most home coffees land between $0.25 and $1.00; espresso with milk a bit more.
