Campaign Cost Currency Basis Check

Keep campaign costs in their documented currency before calculating a return metric. Preparation only, not an account action.

What to provide

Cost and revenue exports, native currencies, approved conversion rates/dates and import currency setting.

How it works

1. Label native and reporting currencies for every amount.
2. Use only approved rate direction and date; preserve original amounts beside converted values.
3. Calculate return only on comparable cost/revenue scopes and currency. Missing conversion evidence blocks the ratio.
4. Return an arithmetic crosswalk; do not change account currency or import records.

The output

campaign | native cost/currency | rate/date | reporting cost | revenue scope | valid ratio | gap

Worked fictional example

Fictional cost 100 EUR at approved 1.1 USD/EUR becomes 110 USD; revenue 220 USD gives revenue/cost 2.0. Without rate, no mixed-currency ratio.

Checks and limits

Keep source versions and original values. Unknowns stay unknown. Use qualified review for regulated, legal or hiring decisions. No live account compatibility test, send, share, schedule, ledger change or payment is authorized.
