Smart Choice Calculator
Discover the opportunity cost of your purchases and find smarter alternatives
What is Smart Choice?
The Smart Choice Calculator shows you what your purchase could become if you invested the money instead. It's not about saying "don't buy things"—it's about understanding the trade-offs.
Plus, our AI suggests practical compromises that let you enjoy what you want while building wealth.
How It Calculates
One-Time Purchases
For single purchases, we calculate what a lump-sum investment could grow to
Formula:
Future Value = Cost × (1 + Return Rate) ^ YearsExample:
$1,000 invested at 7% for 10 years = $1,967
Recurring Expenses
For subscriptions, we show what regular monthly investments would accumulate
Formula:
Future Value = Monthly Cost × [((1 + r)^n - 1) / r]Example:
$50/month at 7% for 10 years = $8,697
