Instantly compare the cost of living across 12,743 cities and 190 countries. Set your home as the baseline (NYC=100, London 80, Berlin 64, Lisbon 51, Bangkok 40, Tbilisi 33), then see your monthly spend equivalent anywhere on the map. Powered by Numbeo's 9.8M+ crowdsourced prices, cross-referenced with OECD PPP 2026.
The cost of living calculator runs on a single, simple formula: destination spend ≈ home spend × (destination index / home index). Indices are anchored to New York City at 100 — the standard Numbeo baseline since 2009. London sits at roughly 80, Berlin near 64, Madrid 58, Lisbon 51, Bangkok 40, Chiang Mai 37, Bali 35, and Tbilisi 33 (Numbeo 2026). Enter your home city, the amount you currently spend each month, and the calculator returns the purchasing-power-equivalent budget anywhere else in the dataset.
A worked example clarifies the maths. A $3,000/mo lifestyle in NYC (index 100) translates to about $2,400 in London (80), $1,530 in Lisbon (51), $1,200 in Bangkok (40) and $990 in Chiang Mai (33). Those are like-for-like baskets: same housing tier, same grocery basket, same dining cadence, same transport. The calculator surfaces both the total and a category breakdown, because rent typically accounts for 35–50% of the basket and behaves very differently from food or transport. A destination can be "cheap" on rent and "expensive" on imported electronics simultaneously — the breakdown is where decisions get made. The full source-by-source weighting is published on the methodology page.
The cheapest cities on the Numbeo 2026 sample, ranked by all-in monthly cost for a comfortable single-person lifestyle. Indices in parentheses are NYC-relative (100 = NYC). For context, the full cheapest countries ranking aggregates these city indices to the country level.
The calculator's primary feed is the Numbeo 2026 cost-of-living database — 12,743+ cities and 9.8M+ crowdsourced prices, the most comprehensive comparable dataset in the public domain. Numbeo's strength is breadth and freshness; its weakness is variance in smaller, lower-sample cities. GeoRank cross-references every headline figure against OECD Purchasing Power Parities 2026 and the World Bank International Comparison Program, which use official government basket pricing. Where the two sources diverge by more than 15%, we flag the city as low-confidence on the live map.
Numbeo is the source. GeoRank is the interface — and the calibration layer on top. Three differences matter for relocation decisions. First, it's home-baselined. Most public calculators ship pre-baked NYC-vs-X or London-vs-X comparisons. GeoRank lets you pin your city — Austin, Manchester, Munich, Brisbane — and every subsequent number is anchored to your actual spend, not a stranger's. Second, it's PPP-aware. The raw cost index tells you nominal price differences; GeoRank surfaces purchasing-power equivalents cross-referenced against OECD PPP 2026, which uses official basket pricing rather than crowdsourcing. Where the two sources disagree, we flag the city.
Third, cost doesn't live in isolation. A $1,400/mo Lisbon lifestyle is only useful information if you also know Lisbon clocks 2,806 sunshine hours per year (ERA5-calibrated against WMO stations), pays 20% flat tax under IFICI for eligible movers, and ranks #7 globally on the Global Peace Index 2025. The map layers cost on top of climate, tax, safety, air quality and internet speed — every pin returns the full picture, not just the price tag. And it's free, with no signup. The methodology page documents every source.
The map combines every layer — cost, sunshine, tax, safety, air — for any pin. Set your home as the baseline and see the deltas instantly.
