Compare personal fee assumptions

What is added and what remains unknown

The raw fee for one trade is the fixed amount plus trade notional multiplied by percentage/100. Apply an explicitly known floor, then cap; an explicit absent bound skips that step. An unknown required input or bound leaves the final fee unknown, even if another component is zero.

The conversion fee uses only the supplied portion and rate. The fixed monthly fee is multiplied by the supplied payment count. A zero converted portion or zero month count means a non-applicable operation costing zero; it does not verify an unknown rate. Totals and A − B exist only with complete required inputs.

Costs may exceed trade notional; the model does not cap them at available cash or execute anything. This is not a recurring-trade calendar, custody cost, inactivity rule, tax calculation, actual tariff or broker recommendation.
