Which is cheaper, Puerto Rico or US Virgin Islands?

Puerto Rico is modestly cheaper than the USVI on average. Puerto Rico moderate is $3,600 per person per month versus the USVI territory-wide average of $3,775, a gap of about $175 a month. Within the USVI, St Croix ($3,600) ties PR, while St Thomas ($3,975) runs noticeably above. The headline gap closes once you look at individual islands and neighbourhoods. The bigger practical differences are scale and infrastructure: PR has 3.2 million residents, full US-mainland banking and chain retail coverage, deep medical infrastructure, and a far larger rental market. USVI has roughly 87,000 residents across three populated islands, thinner inventory in any price band, and an electricity grid that runs 3 to 4 times more expensive than PR’s. Tax incentives are available in both via different programmes (PR’s Act 60, USVI’s EDC). For the full breakdown, see our St Croix cost of living page.
