What this Dominican inflation calculator does
Inflation quietly shrinks what your money can buy. A thousand Dominican pesos kept in a drawer since 2010 still says “1,000” on the bills, but it buys far fewer groceries today. This calculator puts a precise number on that loss using the World Bank’s consumer price index (CPI) for the Dominican Republic, a complete yearly series running from 1960 through 2025.
The entire dataset is baked into the tool, so everything runs in your browser: no network calls, no tracking, and instant results. Pick any two years and the calculator tells you what an amount from one year is worth in the other, how much inflation accumulated in between, and the average annual rate over the period.
The Dominican Republic’s inflation history has real drama in it: the late-1980s crisis pushed annual inflation past 50%, the 2003-2004 banking crisis did it again, and the post-pandemic surge of 2021-2022 briefly doubled the central bank’s target. In calmer stretches, the Banco Central has kept inflation near its 4% goal, which is why long-run averages look moderate despite those spikes.
How to use it
- Enter an amount in Dominican pesos (RD$).
- Pick the start year the money belongs to.
- Pick the end year (2025, the latest available, is preselected).
- Read the three cards: the equivalent amount in end-year pesos, the cumulative inflation between the two years, and the annualized rate.
You can also run it backwards: choose an end year earlier than the start year and the tool shows what a present-day amount was worth in the past.
The math behind it
The core formula compares the CPI level in both years:
equivalent = amount × CPI(end) / CPI(start)
Cumulative inflation is (CPI(end) / CPI(start) − 1) × 100, and the annualized rate takes the n-th root of that ratio, where n is the number of years between the two dates.
Recent year-over-year inflation
Annual average CPI change according to the World Bank:
| Year | Inflation |
|---|---|
| 2016 | 1.62% |
| 2017 | 3.28% |
| 2018 | 3.57% |
| 2019 | 1.81% |
| 2020 | 3.78% |
| 2021 | 8.25% |
| 2022 | 8.81% |
| 2023 | 4.78% |
| 2024 | 3.30% |
| 2025 | 3.87% |
Worked example
What are RD$1,000 from 2010 worth in 2025?
- CPI in 2010: 100 (the series’ base year)
- CPI in 2025: 181.65
- Equivalent: 1,000 × 181.65 / 100 = RD$1,816.50
- Cumulative inflation: (181.65 / 100 − 1) × 100 = 81.65%
- Annualized rate over 15 years: (181.65 / 100)^(1/15) − 1 = 4.06% per year
In plain terms: you need about RD$1,816.50 in 2025 to buy what RD$1,000 bought in 2010. Money that sat idle over those 15 years lost roughly 45% of its purchasing power.
Frequently asked questions
Where does the data come from?
From the World Bank indicator FP.CPI.TOTL (consumer price index, 2010 = 100), which compiles the official figures reported by the Central Bank of the Dominican Republic. The Dominican series is complete from 1960 to 2025 with no missing years.
How often is it updated?
The World Bank releases each year’s figure once a year, usually during the first half of the following year. The data in this tool was retrieved in July 2026, with 2025 as the latest available year; we refresh the series whenever the World Bank publishes a new data point.
Why do my numbers differ from the Central Bank’s inflation reports?
The World Bank series uses the annual average CPI, while the Banco Central usually headlines December-to-December inflation. Both are valid measures answering slightly different questions. In stable years they nearly match; in years when inflation accelerates quickly, such as 2021, they can diverge noticeably.
Does this account for the peso-dollar exchange rate?
No. Everything here is in Dominican pesos and measures domestic purchasing power. Currency depreciation against the US dollar is a related but separate phenomenon that requires exchange-rate data, not the CPI.
Can I use this for salary negotiations or rent adjustments?
As a benchmark, yes: cumulative inflation tells you the minimum raise needed just to preserve purchasing power. Anything below that is a real-terms pay cut. Keep in mind the CPI tracks a national average basket, so your personal cost of living may move differently.
