Open tool

Separate trade risk, cost basis, cash income, and bond yield

Each calculator answers a different planning question. Keep all money inputs in one currency, enter fees consistently, and treat the result as an estimate rather than investment, tax, or legal advice.

Position size starts with the amount you are prepared to lose and the distance from entry to stop, not with a desired profit.
Average purchase cost is arithmetic; the tax cost basis reported by a broker may follow account-specific rules and adjustments.
Dividend yield, current yield, and yield to maturity measure different cash flows and should not be compared as if they were identical.
