How It Works
Choose a base currency and list holdings with local currency values. Enter FX rates to convert everything into one total. Build a sample portfolio with US stocks, eurozone ETFs, and Brazilian ADRs to see how each currency slice contributes to aggregate wealth in your home currency. Add cash in multiple currencies to capture full exposure including idle balances. Label each row with the settlement currency your broker uses so conversions match your statements. Include cash balances in each currency held for travel or business so exposure bars reflect full FX footprint. Eurozone investors with US stocks show USD bar even when brokerage displays EUR account currency.

Eurozone investors with US stocks show USD bar even when brokerage displays EUR account currency.
Review FX exposure bars to see concentration in USD, EUR, BRL, and other currencies. Concentration above 25 percent in any non base currency warrants a deliberate hedge or diversification review. Re run after adding international funds that hold dozens of underlying currencies through a single ticker. Export mental notes on which positions drive each currency bar before rebalancing toward home country bias. Total portfolio value in base currency is the number to compare against net worth goals and withdrawal planning targets. Concentration above twenty five percent in any non base currency warrants deliberate hedge or diversification review. List each position in trade currency then convert with spot table for base currency net worth total. Exposure above twenty five percent in non base currency warrants hedge or diversify review.

The Formula
Local Value = Quantity × Unit Price
Base Value = Local Value × FX Rate (if foreign)
FX Exposure = Currency Total / Portfolio Total
Rates are user supplied spot assumptions. Forward hedging and currency options are not modeled. Use current spot rates for snapshot allocation, not historical averages. ADR and ETF holdings may embed currency exposure not obvious from the ticker symbol alone. Hedged share classes reduce but rarely eliminate underlying currency risk. Forward hedging and options not modeled: spot snapshot only for allocation planning not hedge sizing. Hedged share classes reduce FX exposure not visible from ticker alone: check fund factsheet. Crypto positions denominated in USD still count as USD exposure for bar chart purposes in this tool. ADR tickers hide underlying currency exposure: check revenue geography in fund factsheet.

FAQ
Why convert to a base currency?
Multi currency portfolios expose you to FX risk. Converting all holdings to one base currency reveals true allocation and foreign exposure. A US investor holding EUR denominated bonds may think they are 60 percent equities until FX conversion shows 15 percent implicit euro exposure. Rebalance decisions should start from converted weights, not local currency labels on statements. ADRs and global ETFs often embed currency bets that disappear until you convert every line item. Exposure bar shows percent of total portfolio value denominated in each currency after conversion. Convert all holdings to base currency using your spot rate inputs for true allocation view. Exposure bar shows percent of total portfolio value denominated in each currency after conversion. Convert all holdings to base currency using your spot rate inputs for true allocation view.
What inputs do I need?
Set a base currency, add assets with currency and local value, and enter exchange rates for non base currencies. List each position with quantity and local price so the tool converts consistently. Update rates after major central bank moves to refresh exposure percentages. Include cash balances in each currency if you hold foreign currency accounts for travel or business. Split dual listed shares by the currency of the quote you actually trade to avoid double counting. Spot rate direction matters: quote base per one foreign unit consistently across all rows. Spot rate direction matters: quote base per one foreign unit consistently across all rows.
How do I read FX exposure?
FX exposure shows each currency share of total portfolio value after conversion. Large non base exposure means FX moves affect total wealth. If 40 percent of your portfolio converts from yen, a 10 percent yen decline reduces total wealth roughly 4 percent even when local stock prices are flat. Use exposure bars to set maximum tolerable currency bets alongside sector limits. Revisit exposure after large unhedged purchases abroad or inheritances denominated in foreign cash. ADR and global ETF tickers hide embedded currency exposure: look through to underlying revenue currency mix. ADR and global ETF tickers hide embedded currency exposure: look through to underlying revenue currency mix.
Which exchange rate direction?
Enter rates as units of base currency per one unit of foreign currency (e.g. 1 EUR equals 1.08 USD if base is USD). Reversing the quote direction will double count or understate exposure. Label each rate clearly when mixing multiple foreign currencies. Use the same rate source for all positions on a given day to keep totals consistent. Mid market spot rates work for allocation snapshots; bid ask spreads matter when planning large conversions.
What is saved in my browser?
Asset names, currencies, and exchange rates are saved locally. Unit prices are not persisted. Refresh prices from your broker before rebalancing decisions; stale FX assumptions can misstate which currency dominates your allocation. Clearing browser data removes saved holdings; export key totals before switching devices. Saved rates reflect your last session, not live markets, so update before material trades. Update spot rates after central bank meetings: stale rates misstate which currency dominates allocation bars. Hedged ETF share class reduces currency bar versus unhedged same index fund: check factsheet currency policy. Document FX policy bands beside equity allocation policy so currency drift triggers review same as sector drift.
