Break-Even Investment Return for 10-Year
- Calculate payment difference: $3,330.62 - $2,531.57 = $799.05. $3,330.62 10-year minus $2,531.57 15-year = $799.05 monthly difference to invest.
- Calculate 10-year interest saved: $56,008. $155,682 15-year interest minus $99,674 10-year interest = $56,008 saved by 10-year.
- Find return needed on $799.05 monthly to equal $56,008 after 10 years. Data: Required return is 3.8%. If market returns over 3.8%, 15-year + investing wins. If under 3.8%, 10-year wins.

- Must have discipline to invest difference every month. Many spend $799 difference instead of investing losing benefit. 10-year forces savings.
