Skipping 3 $12 cocktails per week for 10 years
- Drinks per week skipped = 3; Cost per drink = $12; Weeks per year = 52; Annual return = 6%; Years invested = 10.
- Weekly savings = 3 × $12 = $36.
- Annual savings ≈ $36 × 52 = $1,872.
- If invested monthly at 6% for 10 years, those contributions compound into a future value significantly larger than the raw cash saved.
