Have you tried looking into the value of the quality of life taking account of things such as corruption, health care and personal safety?I came across my notes on daily "comfortable" retirement costs in some different countries that are not too cold by my standards calculated from 2020 data presented in a graphic previously posted. Obviously inflation has altered the results but possibly this offers orientation for these select countries.
Here are those particular old ciphers in 2020 US$ amounts per day for a "comfortable" lifestyle average expenditure presented from lower to higher : India = $33.70/d; Colombia = $39.36/d; Mexico = $46.96/d; El Salvador = $52.58/d; Dominican Republic = $52.76/d; Morocco = $52.97/d; Indonesia = $53.07/d; Albania = $53.27/d; Guatemala = $61.95/d; Philippines = $67.46/d; Costa Rica = $67.66; Cyprus = $77.55/d; Panama - $78.38/d; Puerto Rico = $86.53/d; and the USA (on average) = $109.86/day.
What it makes apparent is that, for example, since on average Colombia (in 2020) was $7.50/d less expensive than Mexico the potential (2020) savings was $2,738/year to retire there 5 years ago than in Mexico. Of course this does not include all outlay a retiree may and/or is obligated to make beyond personal in country "comfortable" living expenses.
Money isn't everything, particularly as you get older IMO.
