Formula & Theory - Currency Weight Calculator
The Currency Weight Calculator uses a basic portfolio share formula:
Base value of holding = Amount × FX rate to base
Portfolio total = Sum of base values
Weight = Base value ÷ Portfolio total
| Symbol | Meaning |
|---|---|
| Amount | Holding in the original currency |
| FX rate | Multiplier to convert to base currency |
| Base value | Holding expressed in base currency |
| Weight | Share of total portfolio |
Notes
- The Currency Weight Calculator assumes the FX rate you enter is the right direction (foreign → base). For USD → EUR, use a rate <1; for EUR → USD, use a rate >1.
- For a precise risk view, consider asset class within each currency separately (cash, bonds, equities).
