Rates are historical, not current
Each amount is converted at the rate for the day that amount happened — the order’s date for revenue and costs, the spend date for ad spend. That makes reports reproducible: run the same April report in June and you get the same numbers you got in April.Ad account budgets are different
Budget figures — daily budget, budget remaining, amount spent — aren’t tied to a single date the way an order is. They’re converted at today’s rate, and each row keeps the ad account’s own currency alongside.What doesn’t get converted
- Counts and percentages — order counts, sessions, conversion % have no currency.
- Ratios built from money — ROAS, MER, CPA, CPM are computed from already-converted amounts, so they come out the same whichever currency you use.
Costs you enter yourself
Most costs — order fees, payment processing fees, shipping, fixed and recurring costs — let you pick the currency you actually pay them in. Per-variant product costs are the exception: they’re always in your shop currency. Everything is converted when it appears in reports, so changing your reporting currency never rewrites what you entered.Related
