How it works
Contributions are added to the initial amount to give total money in; the gain is what the position is worth today minus that total.
Example
$10,000 plus $5,000 added, now worth $19,500, is a $4,500 gain and a 30.00% return.

Frequently asked questions
Do these tools use live market data?
No. Nothing is fetched; you enter the prices, rates, and assumptions yourself.
Does the calculator send my numbers anywhere?
No. The calculation runs locally in your browser.
Are projected returns guaranteed?
No. A projection repeats the rate you entered every year, which real markets never do.
