Whether you're new to zero-days-to-expiration or scaling an existing approach, understanding the fundamentals of 0DTE trading is essential before you trade live capital. This guide covers Trading zero days to expiration options requires lightning-fast math. Our 0DTE Profit Calculator is designed to help you instantly compute position size, breakeven points, max profit, and max loss before you enter a trade.

What Is a 0DTE Calculator?

A 0DTE calculator is a tool used by intraday options traders to model their risk and reward. Because 0DTE options expire on the same day, they have a binary outcome: they either expire in-the-money or worthless. Calculating your exact breakeven price and total capital at risk is mandatory before executing.

How to Use the Position Size Calculator

Proper risk management dictates that you should never risk more than 1% to 2% of your account equity on a single trade. If you have a $10,000 account, your max risk per trade is $100 to $200. Use the calculator to ensure that your total premium paid (for long options) or max loss (for credit spreads) stays under this threshold.

Understanding Breakeven for 0DTE

The breakeven point is the price the underlying asset must reach at expiration for your trade to result in zero profit and zero loss.

For complex strategies like the 0DTE Iron Condor or 0DTE Credit Spread, the breakeven includes the net credit received or debit paid.

Expected Move Calculator

Professional traders use implied volatility (IV) to calculate the "expected move" of the underlying asset by the end of the day. A quick rule of thumb for calculating the daily expected move is taking the ATM straddle price. If SPX is at 5000 and the 5000 call/put straddle costs $30, the market is pricing in a 30-point expected move for the day.
