Do not budget Mérida, Mexico from a monthly figure. Build the twelve months, put the summer electricity bill inside them, and then divide — because the single biggest error in every cost of living in Mérida, Mexico estimate you will read is that it was written in a month when the air conditioning was off.

That is the verdict, and the rest of this post is the method. There is no monthly total printed below. That is deliberate, and it is not evasion: a total from someone else’s apartment, in someone else’s colonia, on someone else’s tariff, in a month they have not named, is not your budget. What follows is the list of lines a Mérida month actually has, which of them move and why, and a sitting’s worth of arithmetic that gives you a number you can defend to yourself.

Everything here was checked on 2026-10-08. Where a figure moves — and most of them move — you are told which authority publishes it and where to read it, rather than given a number with an expiry date I cannot see.

Why a cost of living figure for Mérida, Mexico is wrong the moment you write it down

Three mechanisms, and they compound.

The climate is a line item, and it is seasonal. Mérida is hot for a large part of the year and air conditioning is not optional for most foreign readers. That is not a lifestyle observation, it is an entry in the budget that is near zero in January and is the largest variable line in the file by May. A month sampled from the cool half of the year understates the year. A month sampled from the hot half overstates it. Neither is the average, and the average is what you need, because rent is monthly and your income is monthly.

Mexican utilities do not bill monthly. CFE bills most domestic customers on a two-month cycle, so a “monthly electricity cost” is already a derived figure rather than something that arrives in an envelope. Convert bimonthly bills to a monthly figure before you compare them to anything, and keep the original period written beside the number so you know which two months you are looking at.

Half the lines are in pesos and half your thinking is in dollars. If your income is a pension or a portfolio drawdown in USD or CAD and your rent is in pesos, the exchange rate is a line in your budget whether you track it or not. The post on what a dollar income actually buys here takes that apart properly; for this one it is enough to know that your number has a currency and a date on it.

So the unit of budgeting here is the year, and the monthly figure is the output, not the input.

The twelve lines a Mérida month actually has

This is the list. Two of these are usually missing from the estimates that circulate, and one of them is the one that ruins budgets.

  1. Rent. The anchor, in pesos, and the only line most people research. What it buys depends almost entirely on which side of the Periférico you are on and whether the place has a pool — see the colonia decision as arithmetic.
  2. Electricity (CFE). The variable line. Seasonal, bimonthly, tariff-dependent, and capable of stepping to a different price band entirely. Its own section below.
  3. Water (JAPAY). Small and stable for most households. Not zero, and worth reading off an actual bill rather than assuming it is included.
  4. Gas. LP gas, for cooking and often for hot water, bought either as a delivered cylinder or pumped into a stationary tank. It is a purchase, not a metered bill, so it lands irregularly and gets forgotten.
  5. Internet. Fixed, contracted, and dependent on what actually reaches your street rather than what the provider’s coverage map claims.
  6. Mobile. Fixed and small, once you are off roaming.
  7. Groceries and household. The line people assume is the saving, and partly it is — but it splits into market produce, supermarket staples and imported goods, and the imported third behaves like a dollar price.
  8. Eating out and the social line. Elastic. The line that absorbs a budget overrun, which is why it should be stated rather than left as a residual.
  9. Transport. Either a car — insurance, fuel, tenencia and servicing, plus the verificación and parking — or buses, taxis and ride-hailing. These are different budgets, not different amounts of the same budget.
  10. Health cover. IMSS voluntary affiliation, a private policy, or self-insuring, which is a budget decision disguised as a risk decision. Residency and cover are linked: the insurance your visa application wants is where that starts.
  11. Help. Cleaning, a gardener if there is a garden, pool service if there is a pool. Common, cheap by the reader’s home standards, and almost always left out of the comparison that made Mérida look cheap in the first place.
  12. The maintenance line. A cuota de mantenimiento in a privada or condominium, and in any house the running cost of being in a hot, humid climate: AC servicing, a pool pump, a water pump, mosquito screens. Budget it as a monthly amount even though it arrives as occasional invoices.

The two usually missing are 4 and 12. The one that ruins budgets is 2.

The electricity line, and why it is not one number

This is the section that justifies the post. Every other line can be researched by asking someone; this one has a mechanism that has to be understood before any figure means anything.

Read your tariff off the bill, not off an article

CFE’s domestic tariffs are assigned by region according to summer temperature, which is why Yucatán sits on a hotter-climate domestic tariff than central Mexico and why a budget borrowed from someone in Guadalajara does not transfer. The tariff that applies to a given property is printed on that property’s bill. Read it there. That single step is worth more than any figure I could publish, because it is specific to the meter you will actually be paying for, and because it is the input to everything below.

The structure to understand, as CFE publishes it: a subsidised domestic tariff gives a household an allowance of consumption at low per-kWh rates, with higher bands above it, and the allowance is larger during the designated summer period than outside it. The current bands, the per-kWh prices and the summer period’s dates are published by CFE and are revised; read them on CFE’s own tariff pages for the period your bill covers. Checked on 2026-10-08, that is the only place I would take those numbers from — not from here, and not from a relocation guide.

The DAC threshold is a rolling average, not a monthly cap

Here is the part that is genuinely absent from the pages that rank for this topic, and it is the difference between a budget that holds and a budget that breaks in year one.

A household that consumes above its tariff’s high-consumption limit is reclassified to the DAC tariff — Doméstica de Alto Consumo. DAC is not a surcharge on the excess. It is a different, unsubsidised tariff applied to the whole bill, and the jump is large enough that people assume a metering error. The test is not a single billing period: it is based on a rolling average of consumption over a trailing twelve-month window, which has two consequences nobody plans for.

You can fall into DAC in a cool month. The average that trips the threshold was built in the hot months. The bill that announces it can arrive afterwards, which is why the event feels arbitrary and is not.

Getting out takes as long as getting in. Because the test is an average over a trailing window, a single frugal period does not restore the subsidy. You come off DAC when the average comes back down, which means the recovery is measured in months of restraint, not in one.

Practically: the household that runs AC hard across the hot half of the year and does nothing else unusual is the household that needs to know where its threshold is. Find your tariff’s high-consumption limit on CFE’s tariff page, find your consumption history on your bills — it is printed on them — and work out your own headroom. Two later posts on the cost of the climate go further: the summer bill and the subsidy and the twelve-month average that triples your electricity.

What this means for the arithmetic

Do not put “electricity” in your budget as one number. Put in two: a shoulder-season figure and a hot-season figure, with the number of months you expect of each, and then average them. If you are budgeting before you arrive and have no bills of your own, this is the one line where you should ask the landlord for the property’s own CFE history before signing — which is a lease question as much as a weather one, and is why the air-conditioning clause and the clauses that cost foreigners money are written the way they are. A property whose history you cannot see is a property whose largest variable cost you are accepting blind.

Which lines move with the exchange rate, and which don’t

Sort your twelve lines into three groups. This is the step that makes a dollar-funded budget honest.

Peso-sticky. Rent under a signed lease, utilities, local produce, buses, domestic help, Mexican insurance premiums. These are priced in pesos and they do not reprice when the rate moves. If your income is in dollars, a stronger peso makes every one of them more expensive to you, with no change in the number on the bill.

Dollar-tracking. Imported groceries, electronics, international flights, anything bought online from abroad, and some private medical goods. These move roughly with the rate, so they hurt less when the peso strengthens and more when it weakens.

Contract-locked, until it isn’t. Rent again, from a different angle: locked for the term, then renegotiated. Internet and mobile plans likewise. The exposure is not monthly, it is at renewal — which is where a year of exchange-rate movement arrives all at once.

The honest conclusion is that a dollar income does not give you a fixed Mérida budget. It gives you a budget with an exchange-rate term in it, and the right response is a margin rather than a forecast. This site does not predict exchange rates and will not; why the same rule costs more in some years is about the mechanism, not a view.

The lines foreigners leave out

In rough order of how often I see them missing:

Gas. Because it is a purchase and not a bill. Add it.

The maintenance line. A pool is a monthly cost, not a feature. So is a water pump and so is AC servicing, and in this climate servicing is not optional if you want the unit to still be working in May.

Health cover. Self-insuring is a decision with a number attached, and the number is not zero. If you are over 60 the private market and IMSS behave very differently and both have waiting periods or exclusions worth knowing before you choose: the annual premium, the waiting periods and the exclusions.

Residency’s own running cost. Renewals and card fees are real, recurring and payable at counters. They are small against rent and they are not zero, and the fee schedule is INM’s and is revised — check it at the source rather than inheriting a figure.

The first month. Setup costs are not a monthly line at all, and putting them in one is how people conclude Mérida is expensive after thirty days. They belong in their own bucket: what month one costs before you have lived it.

Trips home. If you expect to fly home annually, that is a monthly line divided by twelve. It is also an absence to count against your residency, which is a different problem — the absence rule, counted.

How to build your own number, in one sitting

Twenty minutes with a spreadsheet, and you will have something better than any published estimate including this one.

  1. Write the twelve lines down the left. All twelve, including gas and maintenance.
  2. Write twelve months across the top. Not one column. Twelve.
  3. Fill rent across all twelve at the figure you are actually being quoted, in pesos.
  4. Fill electricity with two values — your shoulder figure and your hot-season figure — across the months you expect of each. If you have the property’s CFE history, use it. If you do not, mark the cells as unknown and treat that as a finding, not a detail.
  5. Fill the fixed lines across twelve: internet, mobile, health cover, maintenance, help.
  6. Fill the elastic lines at what you actually spend now, not at what you hope to spend here. Groceries and eating out are the two lines where people budget their intentions.
  7. Add the annualised lines — flights, renewals, the AC service — as a twelfth each month.
  8. Sum the year. Divide by twelve. That is your monthly figure, and it is the only one worth putting next to an income.
  9. Tag every cell peso-sticky or dollar-tracking, total the peso-sticky half, and note the rate you converted at and the date. That is your exposure.
  10. Add a margin for the rate, not a forecast. A percentage you can absorb without changing how you live.

Keep the sheet. Re-run it in February, because that is when the year’s thresholds reset and when several of the numbers you leaned on will have moved — budgeting around a threshold that moves every year is about exactly that habit.

Three shapes the same budget takes

Not three totals — three different sets of lines. This is the choice that moves the number most, and it is made before any of the figures above are filled in.

Centro, walkable, no car. Transport collapses to buses, taxis and ride-hailing. Rent per square metre is high for the postcard and the building is old, which usually means less efficient cooling and a larger electricity line than the floor area suggests. Noise is real. This is the cheapest shape on paper and the one most sensitive to the electricity mechanism above.

The middle ring, one car. García Ginerés, Itzimná and their neighbours. Transport reappears as a full line — insurance, fuel, servicing. Rent is usually better value per square metre and the building stock is newer. The budget is larger and flatter, with less exposure to any single line.

North of the Periférico, car, often a pool. Rent, transport, maintenance and electricity all rise together, and the pool and the commute are the two lines people underestimate. Ten minutes of driving changes the rent materially, which is the subject of the Periférico as a dividing line.

Pick the shape first. Then fill the sheet. Doing it the other way round produces a number that describes nobody.

If you are comparing Mérida against somewhere else

Then compare like for like, which means comparing twelve-month totals built the same way, not monthly figures collected from different sources. Two of this network’s city sites have run the same exercise for their own cities, on the same structure, so the arithmetic is at least commensurable: a month in Cuenca, itemised and a month in Belgrade, itemised. Cuenca is the closer comparison for a dollar-funded reader — Ecuador uses the US dollar, which removes the exchange-rate term from the budget entirely and replaces it with a different set of problems.

The fuller comparison, with all four cities and the currencies lined up, is four currencies, one budget.

Questions this leaves

Is Mérida cheap? Cheaper than most of the United States and Canada on rent, help and local food, at parity or worse on imported goods and electronics, and with one large seasonal line that most comparisons omit. “Cheap” is the wrong frame; “differently shaped” is the right one.

Can I use someone else’s monthly figure as a starting point? As a sanity check on your own sheet, yes. As the sheet, no — and check which months and which colonia it came from before you even use it as a check.

What if I cannot get the property’s electricity history? Treat that as a negotiating point and a risk. It is the largest variable line in the budget and the landlord has the data.

How often should I redo this? Once in February, when the year’s thresholds reset, and once after your first full hot season, when you finally have your own bills instead of estimates.

The rest of the money decision, one question at a time

What a dollar buys here, which bank will actually open an account for you, how the money gets in, the RFC and when you really need one, the shape of the Mexican tax question, and what the first month costs before any of this applies.
