# Position sizing & risk-reward calculator — no upload

> Calculate position size from account risk, entry, and stop-loss, with risk-reward ratios. Runs in your browser, no upload. Informational only, not advice.

Work out how large a position to take from the amount you're willing to risk, your entry, and your stop-loss, and see the risk-reward ratio. It calculates on your device and is educational, not trading advice.

Consistent risk management, not stock picking, is what keeps traders solvent. Position sizing enforces that: by fixing how much you'll lose if a stop is hit, it tells you exactly how many units to buy regardless of conviction.

The risk-reward ratio then sanity-checks whether the trade is worth taking. For measuring realized returns afterward, use the CAGR/XIRR calculator.

## How to

1. **Set your risk.** Enter account size and the percentage you'll risk per trade.
2. **Enter levels.** Add entry, stop-loss, and target prices.
3. **Read the size.** See position size, risk amount, and risk-reward ratio.

## FAQ

### How is position size calculated?

Risk amount (account × risk %) divided by the per-unit risk (entry minus stop) gives the number of units that keeps your loss within the limit if the stop is hit.

### What is a good risk-reward ratio?

Many traders look for at least 1:2 (risking one to make two), but the right ratio depends on your win rate; the tool shows the ratio so you can judge.

### Is this trading advice?

No. It's a risk-management calculation, not a recommendation to trade or a prediction. Trading carries risk of loss.
