Free Trading Tools
Free tools for learning options and trading. Work out the breakeven and risk of an option trade, the annualized return on a covered call or cash-secured put, or how many shares or contracts to trade. Project how a balance compounds, how long a retirement balance lasts, or what a monthly return really becomes. Every tool here is free and needs no account.
Compound Lab
Set a starting balance, a periodic return and a time horizon, and see what the balance looks like if you reinvest gains instead of withdrawing them. A planning tool, not a prediction.
Open tool →Retirement Withdrawals
Enter a balance, a monthly withdrawal, a return and a number of years to see how long the money lasts and the most you could take each month. Inflation can raise the withdrawal every year.
Open tool →Monthly Returns
Type a return per month, such as 1% or 2%, and see the true yearly rate and what a starting amount and monthly deposits become, with a likely range and a losing-months check.
Open tool →Profit Calculator
Type in the strikes and premiums for a call, a put or a vertical spread and see the breakeven, the maximum profit, the maximum loss, a scenario table and a payoff chart. Add the stock price and days left to see the profit today and before expiration.
Open tool →Annualized Return
Turn the premium on a covered call or a cash-secured put into a return for the period and an annualized return, with your breakeven and downside cushion. Compare up to three trades side by side.
Open tool →Position Size
Work out how many shares or option contracts to trade so a losing trade costs no more than the percent of your account you chose. Includes a risk-level table and a losing-streak chart.
Open tool →For practice on real option chains (about 15 minutes delayed), see Signal Desk. To practice, try the trade simulator and the trading word games on the Practice page.
