The question usually surfaces at reporting time: project expenses were paid in CFA francs, Lebanese pounds or dollars, and the donor expects a report in euros. Which rate applies? The local bank rate on payment day? A project average? For European Commission funding, the answer is a word thousands of grant managers type every month: InforEuro. Applied incorrectly, this exchange rate turns perfectly genuine expenses into unexplained variances — and then into audit findings.
This article explains what the InforEuro rate is, when and how donors require it, which conversion mistakes cost the most, and how an ERP like Abvius automates conversion while filing the applied rate directly into the audit trail.

InforEuro: the European Commission's monthly accounting exchange rate
InforEuro — often written "InfoEuro" — is the accounting exchange rate published monthly by the European Commission (DG Budget). For each currency, a single rate is fixed at the end of the month and applies to the entire following month: the March rate is published in late February and governs every conversion from 1 to 31 March. The rates are freely available online, with decades of history, so a conversion can be reconstructed years after the expense.
The logic is accounting-driven, not financial: this is not the best market rate but a single, enforceable reference. Every actor on a contract — lead NGO, local partners, auditors, Commission services — converts with the same rate, making reports comparable and verifiable. That is exactly what is missing when each country office applies its own bank's rate.
Where to find the rates
InforEuro rates are published on the European Commission's website, by currency and by month, with bulk export. Good practice: archive the monthly rate table (PDF or export) in the project file, so the evidence sits next to the entries it converted.
When is the InforEuro rate mandatory?
The InforEuro rate applies when your funding contract says so — which is the case for the vast majority of EU-budget-funded agreements in external action: DG INTPA / DG NEAR grants (formerly EuropeAid), ECHO funding, and many service contracts. The contract's general conditions specify the applicable conversion method; that text, and that text alone, is authoritative.
Two essential reflexes. First, read the "conversion" article of your general conditions at signature, not at reporting time: the method varies across contract generations and donors. Second, document the chosen method in your financial procedures manual so that headquarters, field bases and partners apply the same rule. A project where HQ converts at InforEuro while the partner uses the local bank rate mechanically produces consolidation gaps.
Other donors (UN agencies, bilateral cooperations, foundations) set their own rules: UN operational rates, the rate of the first instalment received, or actual transfer rates evidenced by bank advices. The principle is unchanged: the contractual method prevails, and it must be applied consistently for the whole project.
Which rate for which expense: the reference month question
Once InforEuro is identified as the reference, the question that concentrates most errors remains: the rate of which month applies to each expense? Depending on the general conditions, the reference month may be the month the expense was incurred, paid or recorded in the accounts; some contracts provide other methods, such as rates linked to instalments received. The difference is not trivial: on a currency depreciating 3% within a month, choosing the wrong month shifts the reported amount by as much.
This is why conversion cannot be an end-of-project bulk exercise on a spreadsheet: it must be attached to each entry, with the rate, the reference month and the euro counter-value traced line by line. In an audit, the verifier recalculates on a sample basis: source document in currency, applicable monthly rate, reported amount. Any break in that chain becomes a question — and often an adjustment.
Conversion mistakes that cost dearly in audits
Five errors come up constantly in expenditure verification reports:
1. The single project rate. Converting 24 months of expenses with one "average" rate simplifies the spreadsheet but contradicts the contractual method. The cumulative gap can reach several percent of the budget.
2. The local bank rate. The rate applied by the country office's bank feels more "real", but if the contract stipulates InforEuro, InforEuro applies. The differential becomes an unjustified variance.
3. The wrong month. Applying the rate of the reporting month rather than the contractually defined month for each expense — the classic error of after-the-fact conversions.
4. Double conversions. An expense paid in local currency, converted to dollars by the partner, then to euros by HQ, with two different references: the final amount can no longer be reconstructed.
5. No trace. The euro amount appears in the report, but neither the rate nor the month applied is documented. Even a correct conversion that cannot be verified will be challenged — see our guide to expense justification.
These errors feed directly into the risk of ineligible expenses: the donor does not dispute that the expense happened, but the amount reported.
Exchange gains and losses: who bears them?
Between the InforEuro rate applied in reports and the rate actually obtained on bank transfers, there is always a gap. General rule on EU funding: exchange losses are not eligible costs — they stay with the organisation, just as gains do. This currency risk must therefore be anticipated in the project's treasury strategy: transfer calendar, currency of project accounts, share of local-currency spending. Our article on multi-currency management details these trade-offs.
How Abvius automates InforEuro conversion
In Abvius, the automatic InforEuro currency conversion module builds the rates into the finance module. Every entry posted in a foreign currency is converted automatically at the contractually defined reference month's rate — no re-keying, no hand-maintained rate table. Above all, the applied rate is filed into the audit pack: for each line, the auditor sees the original currency, the rate, the reference month and the counter-value — the full conversion chain, with no after-the-fact reconstruction.
Multi-currency works end to end: accounts in multiple currencies, HQ-field consolidation, multi-donor analytical allocation, and reporting in each donor's expected format. Per-contract settings let you apply InforEuro on a European agreement and a different method on a UN grant, in the same books, without double entry.
Building a reliable conversion procedure
Step 1 — Map contractual methods. For each active agreement, extract the "conversion" article from the general conditions and record the method in a per-donor factsheet.
Step 2 — Write the rule into the finance manual. One page is enough: reference source, reference month, treatment of exchange differences, HQ/field/partner responsibilities.
Step 3 — Convert at entry, not at reporting. The rate must be applied when the transaction is recorded — the only way to guarantee the correct reference month.
Step 4 — Archive the rates. Keep each month's rate table in the project documentation.
Step 5 — Sample-check before every report. Recalculate a few lines the way the auditor will: document, rate, counter-value.
Mini FAQ
InfoEuro or InforEuro: which spelling is correct?
The European Commission's official service is called "InforEuro", but "InfoEuro" is widely used in the sector. Both refer to the same monthly accounting rate.
Is the InforEuro rate mandatory for all donors?
No. It applies when the contract stipulates it — the general case for European Commission funding. Other donors define their own methods in their general conditions, which always prevail.
Are exchange losses eligible?
As a general rule, no: on EU funding, exchange losses remain with the organisation. Always check the special conditions of your contract.
Can a wrong conversion in a submitted report be corrected?
Yes — and proactively is best: flagging the variance to the donor and correcting it in the next report always beats an audit finding. A clean audit trail makes the correction easy to document.
