Position Size & Risk Calculator (Excel & Google Sheets)

Size every trade by risk, not by feel.

Enter equity, risk % and your stop — get the exact position size (fees included), notional, margin, R:R targets, a liquidation estimate for isolated margin and a DCA / average-entry planner.

What's inside:

• Position size: Risk $, stop distance, fee-adjusted size rounded to your lot step, notional, margin and a risk ladder from 0.25% to 5%.

• Stop vs liquidation: Flags when liquidation would hit before your stop and shows the maximum safe leverage (estimate).

• Liquidation table: Estimated long & short liquidation price and distance for 1x–125x, with a clear disclaimer.

• DCA & average entry: Fill log with true average, break-even after fees, what-if next buy, $ needed to reach a target average, ladder planner.

Works in Microsoft Excel and Google Sheets. Includes a blank copy, a sample-filled copy and a PDF quick-start guide. Instant download.

Liquidation prices are simplified ESTIMATES for isolated-margin linear perpetuals. Exchanges use mark price, tiered maintenance margin, fees and funding — always confirm on your exchange. Not financial advice.
