Mexicans in the US: budget in dollars, spend in pesos
If you work in the US, you earn, pay rent, and eat in dollars, but you probably send $300 to $450 a month to family in Mexico and spend in pesos every time you visit. As of mid-July 2026 the dollar trades near 17.50 pesos, and picking the wrong transfer channel quietly eats 1 to 4 percent of every remittance.
A two-currency budget isn't a niche problem. It's the normal life of millions of people, and almost no US-built budgeting app treats it as anything other than one more generic expense line. This post gathers the July 2026 numbers, average remittance size, effective exchange rate, and the real cost of each transfer channel, along with a worksheet you fill out once a month.
How much do Mexicans in the US actually send home?
In May 2026 the average remittance to Mexico was $404 per transfer, up 5.8% year over year, and the country received $5.611 billion that month, the highest of the year so far. Full-year 2026 remittances are expected to land near $60 billion, below the $61.79 billion sent in 2025.
First-quarter 2026 remittances totaled $14.457 billion, 1.4% above the same period a year earlier. That's not a collapse, but it isn't the fast growth of two or three years ago either. For a household budget, none of that matters as much as one simpler fact: the remittance almost always goes out the same day as payday, so it functions like another fixed bill, not something sent from whatever happens to be left over.
What exchange rate should you actually budget with?
The effective rate, not whatever "dollar to peso" shows in a Google search. Divide the pesos your family confirmed receiving by the dollars you sent, and that number almost always sits below the interbank rate, which as of mid-July 2026 hovers near 17.50, ranging between 17.40 and 17.63 during the week of July 8 to 14.
Mexican inflation eased to 3.37% annually in June 2026, down from 3.94% in May, the lowest reading since December 2020 and inside Banxico's target band. Lower inflation usually calms the peso, but it also softens the yield advantage that draws in foreign capital, and uncertainty around the USMCA review keeps weighing on the exchange rate. None of that changes what your budget needs: use last month's effective rate to plan, not a guess about where the peso is headed.
What's the cheapest way to send money to Mexico?
Wise charges from 0.48% and uses the interbank rate with no added markup, the most transparent option for a direct bank deposit. Remitly often waives the fee on your first transfer, then charges from $1.99 per deposit, but at a softer rate. Western Union applies a 1-2% markup on the dollar for online-to-bank transfers, and stays the most practical choice for cash pickup at a branch or an OXXO.
None of the three wins every case, so the table below breaks out fee, exchange rate, and a $5,000 example so the comparison doesn't depend on whatever each app's landing page promises.
| Wise | Remitly | Western Union | |
|---|---|---|---|
| Fee | From 0.48% | First transfer free, then from $1.99 | 1-2% markup on the dollar |
| Exchange rate | Interbank, no markup | Own markup | Own markup |
| $5,000 sent, example | ~92,380 MXN | ~91,390 MXN (with promo) | Varies by branch |
| Best for | Direct bank deposit | Frequent, fast transfers | Cash pickup at OXXO or a branch |
If your family has a Mexican bank account, Wise almost always wins. If they need cash in hand the same day at a corner store, Western Union earns its higher margin through a pickup network no competitor fully matches. Worth checking both once a quarter, because promotional rates and first-transfer discounts shift often enough that last year's winner isn't always this year's.
How do you build a monthly budget in dollars and pesos?
Seven steps, fifteen minutes once a month: net dollar income, fixed US expenses, a fixed remittance amount, a channel picked by where the money is going, the real effective exchange rate, what stays in dollars, and closing the month against the plan.
Here's a worked example with July 2026 numbers. A worker with $3,000 net monthly income after tax: $950 rent, $150 utilities and phone, $400 food, $200 transport, a total of $1,700 in fixed US expenses. The fixed remittance: $350 a month through Wise, at roughly $1.70 in fees and the interbank rate, so family receives close to 6,090 pesos that month. That leaves $950 after fixed expenses and the remittance, part of it covering variable spend in the US and the rest kept in dollars as a buffer, not converted until it's needed.
The rule that holds the whole exercise together: the remittance amount gets decided before you see what's left over, not after. A fixed dollar figure, revisited every three or four months as your family's situation changes, beats sending "whatever's left" every payday, because whatever's left moves around, and your family in Mexico can't budget against a number that changes without warning.
One line the worksheet above skips on purpose: taxes withheld before that $3,000 net figure even shows up. A W-2 worker already has federal, state, and payroll tax pulled at source, so the net number is close to final. A 1099 contractor, or anyone paid through an ITIN rather than a Social Security number, needs to set aside 20 to 25% of gross income separately for quarterly estimated taxes before applying the rest of this worksheet, otherwise the "net" figure used for rent and remittance planning is really still owed to the IRS.
What happens when the peso gets stronger or weaker?
It depends on which side of the transfer you fix. If you send a fixed dollar amount, a stronger peso means fewer pesos for your family that month, and a weaker peso means more. If instead your family needs a fixed peso number, to cover rent or school tuition, the dollar amount you have to send moves up or down with the exchange rate.
The simplest way to handle this without checking the market every day is to fix the number in whichever currency the priority expense is in. If the priority is a tuition payment or rent in Mexico, fix the peso amount and let the dollar side float. If the priority is not throwing off your own US budget, fix the dollar amount and tell your family the pesos they get can move 5 to 10% from one month to the next. Neither answer is objectively right, and the same tension shows up from the other direction in tracking 7 currencies for 30 days as an expat.
What apps actually handle this, and which is worth using?
Most US-built budgeting apps, including the well-known Mint replacements, assume all your money lives in one American bank and one currency. A remittance shows up as a generic transfer, with nowhere to log the real exchange rate or separate it from the rest of your variable spending.
For anyone who also spends pesos on visits home, the problem doubles: every peso expense either gets converted by hand or falls out of the budget entirely.
Worth saying plainly here: I build Capi, so this section has a declared interest. Capi logs every expense in whatever currency it happened in, by voice note, receipt photo, or Telegram text, and keeps the real exchange rate from that day alongside the original amount rather than a generic one. The remittance gets tagged as a recurring expense separate from everything else, so the end-of-month view shows what went to Mexico and what stayed in the US without combing through a bank statement line by line. The free plan covers up to 30 transactions a month in one currency; Capi Core, with no transaction or currency limit, costs $9.90 a month or $69.90 a year. For a side-by-side against another app built around multiple currencies, the full review is at Capi vs ZenMoney, and the wider category view, ten apps evaluated, is in the 2026 best money tracker ranking.
No app sends the money itself. Wise, Remitly, and Western Union still handle that part. What changes is whether the dollars leaving your account get logged at the real exchange rate or get lost between "transfer" and "miscellaneous" every month. The same problem, applied to someone without a remittance but still living across two currencies through freelance work, is worked through in budgeting on irregular income: the 12-month-average method.
Log the remittance as what it actually is: a fixed expense in two currencies.
Send a voice note or a photo of the transfer receipt and Capi keeps the original amount, that day's exchange rate, and a monthly split between what stayed in the US and what went to Mexico.
Free for up to 30 transactions a month.
FAQ: budgeting in dollars and sending remittances to Mexico
How much does it cost to send money from the US to Mexico in 2026?
It depends on the channel. Wise charges from 0.48% and uses the interbank rate with no extra markup. Remitly often waives the fee on a first transfer, then charges from $1.99 per bank deposit but at a softer rate. Western Union applies a 1-2% markup on the dollar for online-to-bank transfers, and remains the most practical option for cash pickup at OXXO.
What exchange rate should I use for my budget?
The effective rate, not the one Google shows. Divide the pesos your family confirmed receiving by the dollars you sent. As of mid-July 2026 the interbank dollar trades near 17.50 pesos, but every remittance channel deducts its own margin before the money lands.
How do I track a remittance as a fixed expense?
Log it separately from the rest of your spending, with the exact dollar amount that left your account and the date you sent it, not the date your family received it. Treating it as another rent payment, a fixed monthly line, keeps it from blending into variable spend and makes it easy to see whether the amount is still sustainable month to month.
How much does Capi cost?
Capi has a free plan covering up to 30 transactions a month in one currency. Capi Core costs $9.90 a month or $69.90 a year with no transaction or currency limit. Capi Together, for a couple or household, costs $99 a year.
Does this worksheet work if I'm paid hourly or my paycheck changes every two weeks?
Yes, with one adjustment: use the average of your last three paychecks as your base instead of a fixed salary. Calculate the remittance and tax set-aside off that average, not your highest paycheck, so a slow week doesn't leave you short.
