You want the number nobody will give you
Every cost-of-living article you've read was either written by a 24-year-old sharing a flat with 3 roommates, or by a website that has clearly never bought a school uniform. You don't need "Spain is affordable!" You need to know what a month costs for a household with children in it, from someone actually paying the bills.
So here's ours. I'm an American mom living in El Puerto de Santa María, in Cádiz province, with my 2 girls (9 & 10), while my husband finishes his transition from the US. A normal month here costs us about $3,500. The same family's normal month in the US ran about $8,000. Here's where it goes.
The monthly breakdown
| Line | Per month | The honest note |
|---|---|---|
| Rent | $1,600 | 5 minutes from the beach, on purpose. Cheaper exists inland. |
| Phone | $20 | Not a typo. Look at what you pay in the US and grieve. |
| Internet | $40 | Fast enough to run this whole website from the kitchen table. |
| Electric | $60 to 75 | Summer runs higher. The fans earn their keep. |
| Water | $50 to 60 | |
| Private health insurance | $175 | Sanitas, whole family. Kept by choice, more below. |
| Groceries, gas, kids, life | the rest | Everything lands around $3,500 total in a normal month. |
On groceries: I owe you a properly tracked month, and you'll get it in a future update, because "the rest" is exactly the kind of vague line I started this blog to kill. What I can tell you now is that food here is meaningfully cheaper than the US, and 1 category is not: gas. If you keep a car, feed it in your budget like it's a 5th family member.
The rent, and the trap to know before you sign
Our $1,600 is a beach-town premium we chose with open eyes. If you don't need to hear the ocean, Cádiz province gets cheaper fast as you move inland. But wherever you land on price, learn from our scars: getting IN costs more than the listing shows. We paid $4,800 for a set of keys (deposit + agency fee + first month), and renting as a foreigner without Spanish payslips was, and I quote my own field notes, fucking hard.
And in beach towns, ask the question that would have saved us a mid-year move: does this lease survive the summer? Landlords here can triple their income renting to tourists in June, July, and August, so "school year leases" that end in June are everywhere. The full saga, plus every moving cost, is in what our move actually cost.
Healthcare: the $175 I keep paying on purpose
We carry private insurance through Sanitas at $175 a month for the family. I now qualify for Spain's public healthcare, which is genuinely good, so technically I could drop it. I'm keeping it at least another year, and here's the mom-math: wait times for your local doctor are real, and $175 buys the skip-the-line option for a household with 2 children in it. If your kids are past the every-month-something phase, you might decide differently, and both answers are right.
So is Cádiz cheap?
Here's the frame I'd give you over coffee. Cádiz didn't just cut our costs in half. It cut the cost of the life we actually wanted. In the US, $8,000 a month bought us busy. Here, $3,500 buys walking to school, dinner outside on a Tuesday, and a beach my girls treat like a backyard. The number matters, but the exchange rate that really changed is what a dollar buys in lived days.
If you're budgeting your own version: take our $3,500, swap in your rent choice, add international school only if you're choosing it (we paid $25,000 for year 1 and are moving to public school, here's why), and put a real line in for flights back to the US, because family doesn't stop existing when you move.
The pretty videos show you the beach. The budget is what lets you keep standing on it.
The move is math. The belonging is practice.
