What this actually means
The habit is small. The total is not.
$7.00 a day feels like nothing — it is about 3.5 months of streaming services a month. But run it for 10 years and it becomes $32,187, which is about a year of private college tuition.
Interest does the second half of the work
Of that $32,187, you personally put in $25,550. The remaining $6,637 came from interest — money you did not earn by working.
What one skipped day costs you
Skipping a single $7.00 deposit today costs you $10.87 ten years from now. Skipping one day a week costs you $4,583 over a decade.
You are not giving up coffee
You are trading a $7.00 cup for $32,187 in 10 years. Brewing at home costs about $0.50 a cup, so you keep the coffee and roughly 93% of the money.
What if you changed the number?
Same habit, different size. Each one is a full simulation of its own.
