What your Uruguayan pesos are really worth over time
Inflation quietly shrinks the value of money: the same banknote buys a little less every year. Uruguay has lived through extremes — annual inflation topped 100% in the late 1980s and early 1990s — before settling into the moderate single-digit range of the last two decades. Even so, the peso still loses roughly 4% to 10% of its purchasing power per year, so comparing amounts across years without adjusting for inflation is misleading.
This calculator converts an amount of Uruguayan pesos from one year into its equivalent in another year, using the country’s real consumer price index (CPI) as published by the World Bank. The full annual series from 1990 to 2025 is baked directly into the tool, so everything runs in your browser with no network requests and nothing you type ever leaves your device.
How to use it
- Enter the amount in Uruguayan pesos.
- Pick the start year — the year your money belongs to.
- Pick the end year (2025 by default, the latest year with data).
- Read the equivalent amount, the cumulative inflation over the period and the average annual rate.
The math behind it: equivalent = amount × CPI(end) / CPI(start). You can also run it backwards — choose an end year earlier than the start year to see what today’s money was worth in the past.
A decade of Uruguayan inflation
Year-over-year change of the annual-average CPI, computed from the same World Bank series the calculator uses:
| Year | Inflation |
|---|---|
| 2016 | 9.64% |
| 2017 | 6.22% |
| 2018 | 7.61% |
| 2019 | 7.88% |
| 2020 | 9.76% |
| 2021 | 7.75% |
| 2022 | 9.10% |
| 2023 | 5.87% |
| 2024 | 4.85% |
| 2025 | 4.65% |
The recent trend is clearly downward: after the 2020 spike and the 2022 rebound, inflation finally moved inside the central bank’s target range in 2023-2025 — a milestone Uruguay had chased for years.
Worked example
What are $1,000 pesos from 2010 worth today?
- CPI in 2010 = 100 (the base year); CPI in 2025 = 304.15.
- Equivalent: 1,000 × 304.15 / 100 = $3,041.50.
- Cumulative inflation: (304.15 / 100 − 1) × 100 = 204.15%.
- Average annual rate: (304.15 / 100)^(1/15) − 1 = 7.70% per year over 15 years.
In other words, prices roughly tripled in fifteen years: a 2010 grocery run of a thousand pesos costs just over three thousand in 2025.
Frequently asked questions
Where does the data come from and how often is it updated?
From the World Bank indicator FP.CPI.TOTL (consumer price index, annual average, 2010 = 100), which in turn compiles the official figures produced by Uruguay’s national statistics institute (INE). The series is refreshed once a year; the latest year available in this tool is 2025, retrieved in July 2026.
Why might my result differ from the headline figure in the news?
News outlets usually quote the December-to-December change published by the INE, while this tool uses the annual average of the index. For 2024, for instance, the annual average works out to 4.85%, slightly below the year-end print. Both are valid — they simply measure the same phenomenon over different windows.
Which years are covered, and why does it start in 1990?
The World Bank series technically starts in 1960, but because the index is rebased to 2010 = 100, values before 1990 round to nearly zero — a legacy of Uruguay’s high-inflation decades — making them useless for arithmetic. The calculator therefore covers 1990 through 2025 with no gaps.
Can I use this to adjust rent or a contract?
As a ballpark, yes. But Uruguayan leases are legally adjusted using the Unidad Reajustable (UR) or the INE’s official CPI as specified in each contract, with their own dates and rounding rules. For anything legally binding, use the exact index named in your agreement.
Is anything I enter stored or sent anywhere?
No. The CPI table ships inside the page’s code and every calculation happens entirely in your browser — no server calls, no tracking of amounts.
