How This Works
Simple interest is calculated only on the original principal each year. Compound interest is calculated on the principal plus all previously earned interest — which is why it grows faster the longer money is left invested.
Formula
Total = P × (1 + r/12)ⁿ²ᵟ
Example
$10,000 at 8% for 10 years grows to about $22,196 with monthly compounding, but only $18,000 with simple interest.
