Frequently asked questions
What is the latte factor?
The latte factor is the idea that small daily expenses (coffee, lunch out, subscriptions) add up to large amounts over time. $5/day = $1,825/year. Invested at 8% for 30 years, that becomes ~$220K.
How much do small habits cost per year?
A $5 daily coffee = $1,825/year. $15 daily lunch = $5,475/year. $45/month streaming = $540/year. Combined, typical habits can total $7,000–$15,000/year. This calculator shows the exact annual and long-term impact.
What if I invested that money instead?
At 8% annual return, $600/month ($7,200/year) in habits becomes ~$900K in 30 years. Cut one habit and invest the difference—even $50/month becomes ~$75K over 30 years. The calculator shows 5-, 10-, 20-, and 30-year projections.
Which habit costs the most long-term?
Usually daily habits (coffee, lunch out) because they repeat 365 times. A $15/day lunch = $5,475/year and ~$670K in 30 years at 8%. The calculator ranks your habits by long-term cost so you can target the biggest leak first.
