How it works

Profit = (sell − buy) × shares − fees.

ROI = profit ÷ cost basis.

Formula

Profit = (Sell − Buy) × Shares − Fees
ROI = Profit / Cost basis

  • Comparing ROI across multiple trades.
  • Quick what-if for taxes before harvesting gains/losses.

Tips & cautions

  • Include all fees to avoid overestimating profit.
  • Use ROI to compare trades with different sizes.
  • Pair with capital gains tax calculator to estimate after-tax results.
  • Does not include taxes, FX effects, or partial fills with different prices.
  • Assumes a single buy and sell price; complex lots may need weighted cost basis.

Worked examples

  • Profit = $1,500
  • ROI = 30%

50 shares, buy $120, sell $135, $10 fees

  • Profit = $740
  • ROI ≈ 12.3%

FAQs

Does this include taxes?
No. It shows gross profit after fees. Use a capital gains calculator for estimated taxes.
What about FX conversion?
Not included. If trading foreign markets, account for FX gains/losses separately.
Can I use this for crypto?
Yes—the math works for any asset with buy/sell price and fees.
How do I handle multiple fills?
Use your weighted average buy/sell price and total fees to approximate combined profit.
Why include ROI?
ROI normalizes profit relative to cost basis so you can compare trades of different sizes.
