Will prices there rise faster than at home, and what does a falling currency do?

After 2030, prices rise at. Up to 2030 the IMF’s projection is used. The averages are the country’s own, to 2024.

Or try a yearly fall of your own. How much more local currency one US dollar buys each year. Leave empty to skip.

Year by year. Spending today is for 2026 and already holds the IMF’s 2026 figure. Year 2027 uses the IMF’s 2027 projection, 2028 to 2030 its average for those years (IMF World Economic Outlook, as held in the finance database read 2026-10-11); after 2030 the rate you chose. A projection is not a forecast.

What the currency does to a month of spending, 10 years ahead. The local currency falling more than prices rise makes a fixed US$ amount buy more; prices rising faster than the currency falls makes it buy less. A fixed local-currency income is worth less in US$ the more the currency falls. The plan’s rule held within 5% in about 1 in 5 of the countries tested over 20 years, and over the last 10 years every one of them got less expensive for a dollar holder (Data Crossing report, 2026-10-10): treat these as a range, not one value.

What happened over the past 5, 10 and 20 years. Windows end in 2024.

Windows that cross a euro adoption are restated. A positive currency figure means the local currency bought less of the dollar each year. “Cost against the US” below 1 means the place got less expensive for a dollar holder than US prices alone would say.

How far currencies fell, by the country’s inflation band. Ten-year windows to 2024 over every economy in the World Bank file, by the inflation band the window itself sits in. Mexico sits in the “3 to 8%” band on the IMF 2026 to 2030 projection.

A month of spending in US dollars. Same local prices in every line (the IMF path, then its own 10-year average); only the exchange rate differs. Log scale.
