Latte-Faktor
How to Use This Latte Factor Calculator
This calculator shows what a small daily or recurring expense — coffee, lunch out, impulse spending — actually costs over a lifetime if that money were invested instead.
How It’s Calculated
Future Value = Daily Amount × 365 × [ ((1 + r)^years − 1) / r ]
The recurring spend is treated as an ongoing contribution to a compound growth projection.
Example
A $6 per day coffee habit ($2,190 per year) invested at 7% annually for 30 years grows to roughly $220,000, illustrating the outsized long-run cost of small recurring spending.
Frequently Asked Questions
Is the “latte factor” concept realistic financial advice?
It’s a useful illustration of compounding, but critics note it can overstate the impact of small purchases relative to bigger levers like income growth or housing costs. It’s best used as motivation, not a full plan.
What return rate should I use for this projection?
A conservative long-run stock market average of 6% to 7% after inflation is common, but the actual number depends entirely on where that money would realistically be invested.
Does cutting one small expense really matter?
In isolation, modestly — the real value is in what it demonstrates about consistent saving and compounding, which applies to any recurring amount redirected toward investing.
