For millions of retirees, the math on Social Security alone just doesn’t add up back home. Following a 2.8% cost-of-living adjustment from 2025, the average Social Security retirement benefit is approximately $2,083 per month as of May 2026, equivalent to just under $25,000 per year. That sounds modest until you compare it against typical American living costs, which is exactly why a growing number of retirees are looking overseas.
Moving abroad doesn’t mean sacrificing quality of life. Many international cities offer lower costs of living and access to affordable health care, making it possible to live on Social Security alone. The seven countries below consistently show up in retirement indexes, expat surveys, and cost-of-living comparisons as places where a modest monthly check can stretch into a genuinely comfortable lifestyle.
1. Mexico
Mexico remains the top choice for American retirees, and the numbers explain why. Mexico is the most popular destination for American retirees abroad, with large established expat communities and proximity to the U.S. for family visits. The peso’s exchange rate does a lot of heavy lifting for anyone living on a fixed income, since your $2,076 converts to roughly 35,889 Mexican pesos each month.
Beyond the currency advantage, Mexico offers something harder to quantify: familiarity and ease of transition. Coastal towns like Mazatlán, colonial cities like San Miguel de Allende, and Lake Chapala’s expat hub all offer lower rents, cheaper groceries, and accessible private healthcare compared to most U.S. cities. Combined with a short flight home for holidays or emergencies, it’s easy to see why so many retirees choose Mexico as their first stop abroad.
2. Portugal
Portugal has become something of a darling among American retirees seeking European charm without European prices. According to Portugal’s Agency for Integration, Migration and Asylum, 19,258 US citizens lived in the country in 2024, giving new American retirees access to familiar networks and a smoother adjustment period. Costs in the capital are notably lower than back home, since Lisbon’s overall cost of living, including rent, is 30 to 50 percent lower than places like New York City or San Francisco.
Smaller cities push the savings even further. Living in Braga or Coimbra costs approximately $1,400 to $1,700 per month, and while Portugal costs more than Southeast Asia or Latin America, it offers EU healthcare access, a mild climate, English widely spoken, and a totalization agreement with the U.S. that eliminates dual Social Security taxation. Healthcare access adds another layer of security, since Portugal has a universal healthcare system called Serviço Nacional de Saúde, which provides free healthcare for children under 18 and people over 65 who contribute to Social Security.
3. Spain
Spain consistently ranks among the most livable retirement destinations in Europe, and cost is a big part of the appeal. Spain has the lowest cost of living in Western Europe, making it an attractive destination for Americans living on their government benefits. Alicante, on the Costa Blanca, is a standout example, since Spain’s sunny seaside city of Alicante offers retirees a high quality of life on a modest Social Security budget.
Cities like Valencia and Málaga show just how far the average check can go. Living in Valencia or Malaga costs approximately $1,500 to $1,900 per month, and the upper end still leaves a monthly surplus on the average benefit, while Spain’s infrastructure and healthcare are among Europe’s best. Add in world-class public transit, walkable historic centers, and a genuinely social culture built around long meals and plazas, and it’s clear why Spain draws so many American retirees each year.
4. Costa Rica
Costa Rica has built its reputation on stability, healthcare, and a climate that rarely disappoints. With its tropical climate, universal health care system and low cost of living, Costa Rica is a popular pick among expats chasing a slower pace of life. On the tax front, the country is particularly friendly to fixed-income retirees, since it is ideal for Americans who want to protect their retirement income abroad and ranks first for tax optimization in the GCS Retirement Index for US Citizens, thanks to its territorial tax system, which means foreign income generally escapes local taxation.
Community matters too, and Costa Rica delivers on that front. Established expat clusters in the Central Valley and along the Pacific coast mean newcomers rarely feel isolated, with English-speaking clinics, familiar grocery items, and long-running social networks already in place. That combination of low taxes, a public health system open to residents, and a well-worn path for newcomers keeps Costa Rica near the top of nearly every retirement ranking year after year.
5. Panama
Panama’s Pensionado program is one of the most retiree-friendly visa schemes in the world, and it pairs well with a fixed Social Security income. Panama uses a territorial tax system, so foreign pensions, Social Security, and most income earned outside Panama generally fall outside Panamanian tax. The visa itself is accessible for most retirees, since the common visa is the Pensionado, with a lifetime pension requirement starting at $1,000/month for a single applicant, and healthcare is a mix of public and private, with most US retirees using private insurance.
Budget-wise, Panama offers real flexibility depending on where you settle. The estimated monthly budget runs $1,800 to $2,500 outside Panama City, which leaves a comfortable cushion for someone drawing the average Social Security check. Mountain towns like Boquete and beach communities along the Pacific coast tend to run cheaper still, making Panama one of the more forgiving countries for retirees who want their benefit to cover more than just the basics.
6. Ecuador
Ecuador appeals to a specific kind of retiree: someone who values simplicity, low costs, and dollar-denominated peace of mind. Because Ecuador uses the U.S. dollar as its official currency, there’s no exchange rate risk to worry about, and Social Security deposits clear the same as in the U.S., prices are quoted in dollars, and the money math stays simple. That alone removes one of the biggest sources of financial anxiety for retirees living abroad.
Beyond the currency convenience, Ecuador offers dramatic variety within a small footprint. Perfect weather, ultra-low costs, established expat infrastructure, Spanish colonial beauty, and access to adventure make it a fit for retirees who want quality of life over luxury amenities. Cuenca, in particular, has built a loyal expat following thanks to its colonial architecture, temperate climate, and costs that routinely undercut most of Central America.
7. Thailand
Thailand offers something few countries on this list can match: first-rate medical care at a fraction of Western prices. Thailand’s state-of-the-art healthcare facilities are well documented as world-class, and the country also makes staying healthy effortless, with gyms, yoga studios, lush city walking parks, and expansive seaside footpaths encouraging daily movement. For retirees on a fixed income, that combination of quality care and low overhead cost is hard to beat anywhere else in Asia.
Visa options have also become more flexible in recent years. Thailand welcomes expats with flexible visa options, including the standard retirement visa, the new 10-year Long-Term Resident visa for higher-income retirees or investors, and a Digital Nomad visa for remote workers. Coastal towns like Hua Hin and Chiang Mai’s inland charm both offer retirees a lifestyle that would cost several times more back in the United States, all while keeping healthcare quality high and daily expenses low.
Choosing where to retire on Social Security alone really comes down to what matters most to you personally, whether that’s staying close to home in Mexico, embracing European culture in Portugal or Spain, or chasing warm weather and dollar simplicity in Ecuador. What all seven of these countries share is a cost structure that lets an average monthly benefit go noticeably further than it would in most American cities. None of this happens automatically, though. Anyone considering the move should research local visa requirements, healthcare enrollment rules, and how U.S. tax obligations follow you abroad before packing a single box. Done thoughtfully, though, a modest Social Security check can fund a retirement that feels anything but modest.
