Percentage and planning tools
Percentage, reverse-percentage, weighted-average, original-price, and progress tools show the formula used alongside the result. Percentage change requires a positive non-zero starting value. Time tools use browser internationalisation data and selected IANA time-zone identifiers; they do not know personal availability, local holidays, or every calendar rule.
Salary scenario tool
The take-home pay tool does not retrieve a tax table or calculate an official tax liability. It subtracts a rate and other deductions entered by the visitor from gross monthly pay. The visitor is responsible for obtaining any tax or payroll assumption from an appropriate current official source.
Compound-return illustration
The compound-return tool uses a user-entered annual nominal rate compounded monthly, a starting amount, and optional equal monthly contributions. It reports total user-entered contributions separately from calculated growth or loss. It does not account for real-world sequence of returns, fees, tax, inflation, withdrawals, or product-specific terms unless a visitor independently adjusts an input.
Trade and stop-distance arithmetic
The trade-outcome tool applies simple long or short price movement multiplied by units and subtracts total user-entered fees. The manual ticker, forex, and futures risk tool links a visitor-entered risk percentage and money amount, then divides the chosen money amount by price distance × a visitor-entered or starter-preset multiplier × a visitor-entered account-currency factor. It does not fetch market prices, verify a ticker, know broker or exchange specifications, calculate margin, recommend a trade, predict a result, model leverage, or guarantee a stop execution price.
Privacy
Calculator values run in the visitor’s browser. No account is required. See the Privacy Policy for the separate contact-form and hosting information.
