Stock Profit Calculator

It compares the cost of buying a stated number of shares with the net proceeds from selling the same quantity. This page reports dollar profit or loss, return on total purchase cost, per-share result, price change, total fees, and the fee-adjusted break-even sale price.

Yes. The result is then an unrealized or hypothetical estimate, not cash you have received. An actual sale can differ because the price moves and because spread, slippage, or fees may apply.

Yes. Enter any positive share quantity. The same multiplication works for 2.5 shares as for 250 shares, provided your buy price and sell/current price are per share.

For the whole measured transaction. If a broker charged $4.95 to buy the entire position, enter 4.95 once. Do not multiply it by the share count.

The arithmetic works if every monetary input uses the same currency, but the interface displays dollar signs and performs no conversion. Interpret the output in the currency you consistently entered.

Use the cost basis per share for the exact shares being measured. The Stock Average Calculator can find a weighted average, but a taxable sale may require specific-lot or FIFO rules rather than a simple average.

Net profit or loss equals sell price times shares, minus the sell fee, minus buy price times shares, minus the buy fee. Written as one expression: (sell price × shares − sell fee) − (buy price × shares + buy fee).

Divide net profit or loss by total purchase cost and multiply by 100. Total purchase cost is buy price times shares plus the buy fee. This makes fees part of the capital actually committed.

Price change compares only sell price with buy price. ROI on this page uses net profit after entered fees divided by total purchase cost including the buy fee. With zero fees the two percentages match; with fees they do not.

The calculator divides net profit or loss after both entered fees by the number of shares. That spreads transaction-level fees across the measured quantity.

Add total purchase cost and the expected sell fee, then divide by shares. The resulting sale price makes net proceeds equal total cost. With no fees, break-even is the buy price.

It is a loss: net sale proceeds are lower than total purchase cost. The displayed return and per-share result are negative by the same economic direction.

Cost basis is generally the amount paid for an investment, including acquisition costs, subject to later adjustments. It is the starting point for figuring gain or loss, but the correct basis for a taxable sale can depend on the shares and events involved.

For US tax context, IRS Publication 550 says stock basis is generally purchase price plus costs of purchase such as commissions and transfer fees. This calculator adds the entered buy fee to total cost, but it does not determine your reportable tax basis.

It reduces net sale proceeds dollar for dollar. It also raises the sale price needed to break even because the position must recover both purchase-side and sale-side costs.

Possible causes include a different tax lot, adjusted basis, accrued or regulatory fees, currency conversion, spread, fractional rounding, dividends, or a broker view that reports unrealized P/L using a different price. Compare the substituted figures with the broker's trade confirmation.

A split changes the share count and per-share basis without changing total basis at the split moment. Enter the post-split shares and adjusted per-share basis; do not mix a pre-split price with a post-split share count.

They can. Reinvesting a dividend buys additional shares with their own basis. Cash dividends normally affect total return but not this price-only transaction result. Use broker records for the adjusted basis of shares sold.

No. Tax depends on jurisdiction, holding period, account type, lot identification, basis adjustments, loss rules, and personal circumstances. The result is pre-tax arithmetic, not a tax estimate or filing calculation.

No. It is the simple return for the measured buy-to-sell price change, regardless of whether the holding period was one day or ten years. Annualizing requires dates and a separate convention.

No. This calculator measures the share transaction only. Cash dividends would add to total return, while reinvested dividends create additional shares and basis. The DRIP Calculator handles a different reinvestment task.

Not reliably. Short positions can include borrow fees and dividends owed, while margin adds interest and liquidation mechanics. Those assumptions are intentionally outside this one-long-position calculator.

Yes. Copy link puts the five inputs into the URL so the same result opens immediately. The values are not stored by CalcStocks, but anyone who receives the URL can read them.

The calculation runs in your browser and the inputs are not sent to CalcStocks. The output is arithmetic from values you supplied; it is not investment, tax, or legal advice and does not tell you whether to buy, hold, or sell.
