Four quick calculators for the numbers that quietly drive investing decisions. Each one is simple arithmetic — not a projection and not a recommendation — meant to make an idea click. For the real thing on real funds, open the tool.
A 0.75% fee looks small. Over 30 years on the same money it quietly takes a huge slice of your ending balance. Drag the fee and see.
After −50% you need +100% to get back to even, not +50%. See the required gain for any fall.
A simple compounding picture of putting money in all at once vs monthly. The honest caveat: real results depend on timing and the market’s path.
A +315% cumulative return is not +31.5% a year. Convert either way and see why compounding is not linear.
