Estimated net trade profit
Tax rules differ by country, account type, holding period and loss treatment. The tax field is a simple percentage of a positive trade gain, not a tax return calculation.
Stock profit is sale proceeds minus purchase cost, buy and sell fees, and any modeled tax on a positive gain. Enter the two prices and number of shares to see net profit, return on cash invested and the sell price needed to break even. Scenario cards show how the result changes at nearby exit prices.
Net profit includes both trading fees and the simple tax assumption. ROI measures that profit against purchase cash, while break-even solves for the sell price that recovers purchase cost and transaction fees before tax.
The estimate excludes fixed fees, bid-ask spread, currency conversion, tax lots, loss offsets and holding-period rules. Actual proceeds can differ from a quote because of execution price and liquidity.
Inputs are applied directly to standard finance formulas with monthly compounding where relevant. Results are estimates in the selected currency; they do not include every tax, fee, benefit, market event or local rule. Try a conservative and an optimistic case before making a decision.

Net profit equals sell price × shares, minus buy price × shares, transaction fees and the estimated tax entered for a positive gain.
ROI is net profit divided by the original cash invested, including the modeled purchase fee, expressed as a percentage.
When fees apply, the sale must recover both the purchase cost and transaction charges before net profit reaches zero.
No. Tax depends on residence, account, holding period, other gains and losses, and deductions. The tax slider is only a simple scenario assumption.
