Using the Latte Factor Calculator, choosing any category, how much would saving $$10/$day with a $10\%$ annual interest rate accumulate to over $40$ years?

More than $$1,775,000.$

About $$300,000.$

$$871,482\mathrm{.}15.$

This is a poor question because a $10\%$ annual return would never be achievable without taking unnecessary risk. My life would be better enjoying my lattes.
