Quick start

1. Enter your quantity and entry price.
2. Add fees (both entry and exit if relevant).
3. Set an exit price or leave blank to use the live price.
4. Review P/L, ROI, and breakeven.

Tip: leave Sell/Now Price empty and we'll auto-fetch the live price.

Core Formulas

Below are the core equations the calculator applies behind the scenes. You don't need to memorize them, but seeing them demystifies the results.

What is a Crypto Profit Calculator?

A crypto profit calculator helps you estimate potential profit/loss (P/L), return on investment (ROI), and your breakeven price for a trade. It's especially useful when you want to factor in trading fees, different position sizes, and multiple exit targets before you commit real money.

Our calculator runs entirely in your browser no sign-up, no server-side storage. Prices are fetched from public market APIs purely to save you time when you choose to use the live price.

Worked Example (Spot Trade)

1. Quantity: 0.8 ETH
2. Entry: $4,400
3. Exit target: $4,900
4. Fees: 0.1% per side (entry + exit)

Entry cost ≈ 0.8×4,400 = $3,520. Total fee ≈ 0.2% of notional (both sides) ≈ $7.04. P/L before fees = (4,900 − 4,400) × 0.8 = $400. Final P/L ≈ 400 − 7.04 = $392.96.
ROI ≈ 392.96 ÷ 3,520 = 11.17%. Breakeven ≈ 4,400 + (7.04 ÷ 0.8) ≈ $4,408.80.

Tip: Leave Sell/Now Price empty to use the live market price. The panel updates automatically.

Advanced: Fees, Slippage, and DCA

1) Fees

Include both sides of the trade. Some exchanges charge different maker/taker schedules; if you're unsure, enter the taker rate.

2) Slippage

For thin books, you may not get filled at a single price. Add a conservative buffer to your exit to reflect likely execution.

3) Dollar-Cost Averaging (DCA)

Adding to a position changes your average entry. Use the DCA helper to merge fills and update breakeven instantly.

Position Sizing & Risk Management

Smart sizing prevents a string of small losses from knocking you out of the game.

• Define a max risk per idea (e.g., 0.5–2% of your account).
• Use Position Size to back into quantity from your stop distance.
• Prefer asymmetric trades: risk $1 to try to make $2+.

Scenario Planner

Try these quick scenarios directly inside the calculator:

• Break-even check: Enter quantity + entry + fees; leave exit blank. The breakeven line shows the minimum price to avoid loss.
• Target ladder: Duplicate the panel with different exits to see how partial profits change total P/L.
• Fee sensitivity: Bump your fee by 0.05% increments to see the impact on ROI.

Common Mistakes (Extended)

• Ignoring all-in fees (entry, exit, gas, borrow/funding).
• Moving stops further away after entry (emotional trading).
• Confusing position P/L with account P/L: sizing matters.
• Trading during illiquid hours — spreads widen, slippage grows.
• Using leverage to "chase" a missed entry without understanding liquidation price.

Glossary

• P/L: Profit or loss in currency terms.
• ROI: Profit or loss relative to initial capital (percentage).
• Breakeven: Price where P/L becomes zero after fees.
• Slippage: Execution price difference versus intended price.
• Maker/Taker: Fee schedule depending on whether you add or remove liquidity.
