Is this tax, accounting, or legal advice?

No. The calculator is an estimating tool for discussion only. It is not a formal statement, settlement, or tax advice.

Why must ownership percentages total 100%?

When you allocate by ownership share, the percentages need to add up so the full cost is assigned once.

Does currency selection convert exchange rates?

No. Currency is for display and formatting only. Amounts are not converted between currencies.
