# Converting USD to EUR for a business: timing, cost and control

How US companies convert dollars to euros: comparing rates with the mid-market, bank vs fintech margins, planned conversions, forwards, limit orders and holding euros.

## Key takeaways

- The cost of a conversion is the margin between your rate and the mid-market rate, plus any fee.
- Bank margins are often far wider than fintech margins; compare on the same amount at the same time.
- Converting in planned amounts, not every payment, cuts transactions and helps forecasting.
- Forward contracts can fix a rate for future payments; they suit predictable, larger needs.

A US company with a team or suppliers in Europe converts dollars to euros every month. Small differences in rate add up across a year.

## Where the cost sits

| Component | Visible? |
|---|---|
| Fee per conversion | Usually |
| Margin over mid-market | In the rate |
| Wire fee to send euros | Usually |

On $50,000 a month, a 2% margin costs $1,000. A 0.5% margin costs $250. Over a year, $9,000 difference.

## How to check your margin

1. Note the rate you received and the time.
2. Look up the mid-market rate at the same time.
3. Divide the difference by the mid-market rate.

## Ways to reduce it

- Use a provider with a published margin.
- Convert twice a month in planned amounts, not per payment.
- Hold euros from European revenue and pay euro costs from them.
- For large known payments, consider a forward. See [FX forward contracts explained](/blog/fx-forward-contracts-explained).

## Paying into the United States: the local rail

| What | Detail |
|---|---|
| Local rail | ACH for batch payments; RTP and FedNow for instant transfers |
| Run by | Nacha for ACH; The Clearing House for RTP; the Federal Reserve for FedNow |
| Settlement | Same-day ACH within the business day, standard ACH the next; RTP and FedNow in seconds, 24/7, where both banks take part |

## Where Rivet fits

Rivet converts between USD and EUR at a rate shown before you confirm, from 0.80% on Starter, 0.50% on Growth and 0.30% on Scale, and holds euros with an IBAN on Growth so you can pay European costs directly. Rivet is not a bank; regulated partner institutions hold the funds. See [mid-market rate and FX markup](/blog/mid-market-rate-and-fx-markup).

## Questions

### What is the best way to convert USD to EUR for a business?

Use a provider with a published margin close to mid-market, convert in planned amounts, and hold euros where you spend them.

### What is the mid-market rate?

The midpoint between buy and sell rates in the wholesale market. Publications such as the ECB's reference rates and the Federal Reserve's H.10 give benchmarks.

### Should I use a forward contract?

If you have large, predictable euro payments and want certainty, a forward can help. It locks in a rate, both ways.

### How do I know my margin?

Compare the rate you got with the mid-market rate at the same moment, and express the difference as a percentage.
