What the Stock Profit Calculator does
The calculator models one stock position and one sale price to estimate proceeds, profit, return and break-even price.
How to use the Stock Profit Calculator
Enter the assumptions, add rows where the page supports them, choose Calculate, then review the result card, detailed table, visual comparison and CSV export.

- Results are deterministic estimates from the values entered.
Formula or calculation method
Net profit = net sale proceeds + cash dividends - total acquisition cost. Return = net profit / total acquisition cost x 100.
Variables
Shares, purchase price, sale price, fees and dividends determine the result.
Assumptions
No tax calculation is included.
No live stock prices are fetched.
The result is not a buy, hold or sell recommendation.
Calculation steps
Calculate acquisition cost.
Calculate net sale proceeds.
Add dividends and subtract cost.
Calculate return and break-even sale price.
Result interpretation
Positive profit means modeled proceeds plus dividends exceed acquisition cost. Negative profit means a modeled loss.
Worked examples
100 shares bought at 50 with 10 buy fee, sold at 65 with 10 sell fee and 200 dividends gives 5,010 acquisition cost, 6,490 net proceeds, 1,680 profit and 33.532934% return.
Limitations
Taxes, bid/ask spreads, live prices and portfolio risk are excluded.
