Send money home
Your first transfer is free and arrives in seconds
Most people who send money to Mexico look at the fee and stop there. It is the most visible number, the one highlighted in advertisements. But there is another cost, less obvious and sometimes larger, that almost no one checks before sending.
The real cost of sending money to Mexico is not just the fee: it is the fee plus the margin that the service applies to the exchange rate. Ignoring one of the two can cause your family member to receive significantly fewer pesos, even if the fee seems low.
The most common mistake when looking for the best exchange rate to send to Mexico
When someone looks for where to send money to Mexico, they generally compare how much the service charges in fees. If one option charges $5 and another charges $15, the decision seems clear. But that analysis is incomplete.
What also determines how many pesos your family member receives is the exchange rate that the service applies. And here is the point that many do not consider: money transfer services do not use the market exchange rate. They use their own, with an incorporated exchange margin.
How the exchange margin works in practice
Suppose the market exchange rate that day is 18.00 pesos per dollar. A service might offer you 17.50 pesos per dollar. That difference of 0.50 pesos per dollar does not appear as a "fee" anywhere. It is simply reflected in how many pesos your family member receives.
If you send $200 with that margin, your family member receives 3,500 pesos instead of 3,600 pesos: a difference of 100 pesos that equals $5.56. Add that up over a month or a year of transfers and the impact is real.
When you send $200 with an exchange margin of 0.50 pesos per dollar, your family member receives 100 pesos less than if you used the market exchange rate. At 12 transfers per year, that equals more than $66 lost in invisible margins.
How to evaluate if the exchange rate you are offered is good
To know if the exchange rate offered by a service is competitive, you need two pieces of data: the market reference exchange rate and the exchange rate offered by the service.
The reference exchange rate: where to check it
The interbank exchange rate, also called the interbank rate, is the price at which banks buy and sell currencies among themselves. No transfer service gives you exactly that price, but it is the most useful point of comparison because no provider can offer you a better exchange rate than that without losing money.
You can check it at:
- XE.com in real time
- Banco de México (Banxico), which publishes the FIX exchange rate daily
How to calculate the margin applied by a service
Once you have the reference exchange rate, the comparison is straightforward:
- Check the MXN/USD exchange rate for the day on XE.com or Banxico
- Enter the simulator for the service you want to evaluate and note the exchange rate they offer for your amount.
- Subtract: (reference exchange rate) minus (service exchange rate) = margin per dollar.
- Multiply the margin by the amount you are going to send to see the cost in pesos.
If a service offers a low margin but charges a high Fee, it may still be more expensive than another with a higher margin and a low fee. The only valid comparison is the total cost.
How to calculate the total cost of a transfer to Mexico: fee plus exchange rate.
The total cost of a transfer has two components: the fixed or percentage fee charged by the service, and the margin applied to the exchange rate. Optimizing only one of the two does not guarantee the best result.
Comparison of fees for sending $3,000 USD to Mexico.
The following table shows the fee costs of the most used services for sending money to Mexico. This information is for reference: rates change, always verify before sending.
| Service | Estimated fee (transfer of $3,000 USD) |
|---|---|
| Western Union | $45.00 USD |
| Wise | $23.91 USD |
| Xoom | $76.49 USD |
| Félix | $2.99 USD per transfer (up to $2,999 per day with verified identity) |
Félix charges a fixed Fee of $2.99 per bank transfer to Mexico, regardless of the amount, always within your sending limits. This means that sending $500 or $2,999 has the same fee cost. The daily limit is $2,999 with verified identity ($1,500 unverified), so an amount of $3,000 cannot be sent in a single day with Félix.
This data is for comparison reference. Rates change frequently. Verify before sending.
The complete comparison: fee plus exchange rate.
A low fee does not guarantee the lowest total cost if the service compensates with a high exchange margin. To choose well, always compare both factors together:
- Check the market exchange rate on XE.com or Banxico that same day.
- Simulate the transfer with every service you are evaluating and note how many pesos your family member will receive.
- Add the fee in dollars converted to pesos at the market exchange rate.
- Compare the total: the service that delivers the most pesos with the lowest combined cost is the one that suits you best.

The 2026 1% tax: an additional cost for cash payments.
As of 2026, international transfers paid in cash from the U.S. are subject to a 1% federal tax on the amount sent. Payments made with a debit card or credit card are exempt. This adds a third layer of cost, in addition to the fee and the exchange margin, specifically for those who pay in cash. For full details, see 1% tax on remittances in 2026.
Frequently asked questions
How do I know what the market exchange rate is?
The most reliable reference exchange rate is the one published by the Bank of Mexico (Banxico) on its official website or the one shown by XE.com in real time. Both reflect the daily interbank rate, which is the starting point for comparing what any transfer service offers.
Does the fee or the exchange rate matter more?
It depends on the amount you send. For small amounts (less than $200), the fee usually has a greater relative impact. For large amounts (more than $500), the exchange margin can cost more than the fee in absolute terms. The correct way to compare is to calculate the total cost: the fee plus the money lost in the exchange rate margin.
Does Félix Pago apply a margin to the exchange rate?
Félix Pago applies the current exchange rate at the time the transfer is processed. To know exactly how many pesos your family member will receive before confirming the transfer, the simulator within the WhatsApp chat shows you the final amount before you authorize the payment.
