About Daily Savings & Latte Factor Calculator

The Daily Savings Calculator (The Latte Factor) demonstrates how cutting small recurring daily habits (coffee, dining out, subscriptions) and investing the saved cash compounds into life-changing wealth.

Formula & Mathematical Calculation

Monthly Investment = Daily Savings × 30.42

Future Value = Monthly Investment × [ ((1 + r/12)^n - 1) / (r/12) ]

Calculation Example
