| Input or result | Example value | Interpretation |
|---|---|---|
| Invoice amount | USD 100,000 | Billing currency before conversion |
| Mid-market rate | 0.9200 EUR per USD | Indicative example, not a live quote |
| Bank spread | 1.5% | Illustrative negotiated spread |
| Receiving bank rate | 0.9062 EUR per USD | 0.9200 × (1 - 0.015) |
| Wire fee | EUR 25 | Illustrative fee in settlement currency |
| Net receipt | EUR 90,595 | 100,000 × 0.9062 - 25 |

Frequently asked questions
How do I calculate the hidden FX spread on an invoice?
Compare the bank's applied rate to the interbank mid-rate at the same timestamp: spread (%) = (applied_rate − mid) / mid × 100. On EM currencies, spreads of 1–3% are common; on majors, 0.3–0.8% at competitive banks.
Which exchange rate should an export invoice use?
Use the currency and rate agreed in the sales contract. For customs, most countries convert at the official rate on the date of entry or bill of entry, such as the CBIC notified rate in India. Banks convert LC proceeds at their own buying rate, so the hidden spread falls on the exporter.
Can an LC be issued in a different currency from the invoice?
Under UCP 600 Art. 18(a)(iii) the commercial invoice must be made out in the same currency as the credit. An invoice in a different currency is a discrepancy, so agree the currency before the credit is issued.
