Compound calculator

A projection, not a forecast. The number it gives you is arithmetic about a rate you chose, not a prediction of anything.

Compounding assumes a steady return every month, which no trader gets. Treat this as a planning tool, not a projection.

Free, and nothing is stored. Check every figure against your own platform before you trade on it. Nothing here is advice, and trading carries risk.

How it works

Compounding is the least controversial arithmetic in trading and the most misused. The formula is not in dispute. What is in dispute is the rate anybody puts into it.

This shows the total, what you deposited, and the growth separately, because those three numbers get conflated constantly. A projection showing a large final balance is often mostly deposits.

The honest use of it is the reverse of how it is usually shown. Instead of asking what 10% a month becomes, put in a rate you have actually achieved over a year and see what that becomes. The gap between the two is where most of the disappointment in this industry lives.

No rate is sustainable simply because it is achievable once. A month is a small sample, and a compound projection assumes every month is the same, which no trading record ever is.
