How it works
Simple interest only charges or earns interest on the original principal. It does not compound, so the growth path is linear rather than exponential.
Examples
$10,000 at 6% for 3 years: simple interest produces $1,800 of interest. This makes it a useful baseline when comparing against compound interest products.
Methodology & assumptions
- Interest = principal × rate × time.
- Tax and inflation are scenario adjustments only.
- The calculator can also show a periodic equivalent interest view.
