Estimate theta trade profit or loss from buy price, sell price, and position size.
Use this theta profit calculator to compare entry price, exit price, and capital committed before or after a trade review. This page is for traders who search by token name and want a quick profit check without rewriting the same trade math by hand. The calculator is designed to give a fast answer, but the quality of the answer still depends on accurate inputs and a clear idea of what decision you are trying to support.
- Enter Buy Price, Sell Price, and Investment Amount using the same units you plan to compare or report.
- Read the main theta profit / loss first, then use the supporting outputs to understand the trade-offs behind that result.
- Compare your numbers with the worked examples below if you want a quick reasonableness check.
The headline number is the profit or loss in dollars, but the implied ROI is just as useful when you compare setups or review trade quality. On this page, the primary output is theta profit / loss.
Scenario 1: Theta bought at 6.5 and sold at 9.8 with $1,500. Inputs used: buyPrice: 6.5, sellPrice: 9.8, investment: 1500. Example result: $761.54. In this theta trade example, the position works out to $761.54, which gives you a quick benchmark for what that move means in cash terms. Scenario 2: Theta bought at 18 and sold at 26 with $2,500. Inputs used: buyPrice: 18, sellPrice: 26, investment: 2500. Example result: $1,111.11. With a larger theta position and a stronger move, the projected trade result is $1,111.11.
Core formula: profit = (investment / buy price) * sell price - investment. The calculator first determines how many coins your investment bought, then values those coins at the exit price to compute profit and ROI.
- ROI tracks price performance, not fees or taxes.
- Large moves scale linearly with your initial investment size.
Use it when you want a clean before-and-after view of how a theta trade changes with different exits or position sizes. Related paths for follow-up analysis include crypto profit calculator, crypto roi calculator, position size calculator, and trade risk calculator.
Most bad outputs come from a few repeated input errors or interpretation mistakes. Use this short checklist before relying on the result.
- Ignoring exchange fees and slippage when comparing small or short-term trades.
- Comparing ROI percentages without checking how much capital was actually at risk.
- Treating an unrealized price target as if it were a guaranteed exit level.
