Inflation in Russia by month: table, seasonality and how to calculate for any period
In January 2026, prices in Russia rose by 1.62% compared to December, which is higher than in the Januaries of 2023‑2025, and in August they fell by 0.08%. Over the nine months of 2026, the cumulative growth amounted to 5.04% compared to December 2025. Below are all monthly values for 2023‑2026 in one table, showing which months prices rise the fastest and when deflation occurs, and explaining how to compile inflation for any period from the monthly figures. Each chart below opens on the website in an interactive form.
Inflation table by month for 2023-2026
Rosstat publishes inflation as the consumer price index (CPI) compared to the previous month. A value of 100.00 means that prices did not change. 100.50 means a rise of 0.5%, 99.60 means a decline of 0.4%. Below are the indices by month, the last row shows how much prices grew over the whole year, from December to December.
| Month | 2023 | 2024 | 2025 | 2026 |
|---|---|---|---|---|
| January | 100.84 | 100.86 | 101.23 | 101.62 |
| February | 100.46 | 100.68 | 100.81 | 100.73 |
| March | 100.37 | 100.39 | 100.65 | 100.60 |
| April | 100.38 | 100.50 | 100.40 | 100.14 |
| May | 100.31 | 100.74 | 100.43 | 100.17 |
| June | 100.37 | 100.64 | 100.20 | 100.87 |
| July | 100.63 | 101.14 | 100.57 | 100.54 |
| August | 100.28 | 100.20 | 99.60 | 99.92 |
| September | 100.87 | 100.48 | 100.34 | 100.35 |
| October | 100.83 | 100.75 | 100.50 | data not available |
| November | 101.11 | 101.43 | 100.42 | data not available |
| December | 100.73 | 101.32 | 100.32 | data not available |
| For the year (December to December) | 107.42 | 109.52 | 105.59 | 105.04 for 9 months |
Rosstat data without the new regions: the footnote to the table states that the series excludes the Donetsk and Luhansk People's Republics, Zaporizhzhia and Kherson regions.
The most notable month in the table is November 2024: 101.43, i.e., prices rose by 1.43% in a single month. Followed by December 2024 at 101.32. This is the peak of the latest inflation surge, after which the pace began to fall: in 2025 prices rose by 5.59% versus 9.52% the year before.
You can view any month since 1991 in the full table of consumer price indices, and the CPI for each year separately is compiled on pages like /inflation/2025.
Which months are the "most expensive" and which are cheap
Inflation has a season. I averaged the monthly indexes for 2015‑2025, excluding 2022: in March of that year prices jumped once by 7.61%, and that single month would break any average.
| Month | Average index | Minimum during period | Maximum during period |
|---|---|---|---|
| January | 101.08 | 100.31 | 103.85 |
| February | 100.68 | 100.21 | 102.22 |
| March | 100.50 | 100.13 | 101.21 |
| April | 100.46 | 100.29 | 100.83 |
| May | 100.43 | 100.27 | 100.74 |
| June | 100.38 | 100.04 | 100.69 |
| July | 100.49 | 100.07 | 101.14 |
| August | 99.98 | 99.46 | 100.35 |
| September | 100.28 | 99.84 | 100.87 |
| October | 100.55 | 100.13 | 101.11 |
| November | 100.68 | 100.22 | 101.43 |
| December | 100.68 | 100.32 | 101.32 |
The picture looks like this:
- January is the most expensive. The start of the year brings price revisions. On average +1.08%, and in 2026 +1.62%.
- Summer and early autumn are the calmest. From June to September the average growth is below 0.5% per month. August is the only month where the average falls below 100: in 2015‑2025 (without 2022) it was 99.98.
- By the end of the year the pace rises again. October, November and December give 0.55‑0.68% on average.
So you cannot compare January with August: a difference of 1.5 percentage points in these months is normal. It is more correct to look year‑over‑year or to calculate cumulative inflation over 12 months.
When prices did not rise but fell
In the monthly table deflation (index below 100) is seen rarely since 2015, and almost always at the end of summer:
- August and September 2017;
- August and September 2019 (99.76 and 99.84);
- August and September 2020 (99.96 and 99.93);
- June, July and August 2022 (99.65, 99.61 and 99.48), when prices retreated after the spring surge;
- August 2025, 99.60;
- August 2026, 99.92.
The reason is seasonal: at the end of summer products from the new harvest become cheaper, and this is visible in the food index (August 2025, 99.09). For more detail on how prices move for individual goods, see the articles about food prices and about potatoes and vegetables.
How to calculate inflation over several months
You cannot simply add monthly percentages: each subsequent month is calculated on already increased prices. You need to multiply the indices. Rosstat gives an example in a footnote to its table: inflation from April to September 2025 is calculated as follows:
100.40 × 100.43 ÷ 100 × 100.20 ÷ 100 × 100.57 ÷ 100 × 99.60 ÷ 100 × 100.34 ÷ 100 = 101.55%
That is, over these six months prices rose by 1.55%, while the sum of monthly add‑ons would give 1.54%. With small numbers the difference is hardly visible, but the longer the period and the higher the inflation, the more noticeable it becomes.
If you do not want to calculate it yourself, there is an inflation calculator: you choose the start and end of the period, it takes Rosstat's monthly indices and multiplies them for you.
What “to December” and “to the previous month” mean
Rosstat's table has two rows. The first, “to the end of the previous month”, is what is shown above. The second, “to December of the previous year”, is the cumulative inflation from the beginning of the year. In it the value for September 2026 equals 105.04: over nine months prices rose by 5.04%.
How much inflation amounted to at the end of each year
If you multiply all twelve months, you get the inflation for the calendar year (December to December):
| Year | Inflation for the year |
|---|---|
| 2019 | 103.04 |
| 2020 | 104.91 |
| 2021 | 108.39 |
| 2022 | 111.94 |
| 2023 | 107.42 |
| 2024 | 109.52 |
| 2025 | 105.59 |
For comparison, in 2019 prices rose by 3.04%, and in 2022 by 11.94%. An analysis of the reasons for each jump and a comparison with other countries can be found in the article on inflation in Russia by year.
Food and non-food items: where the monthly picture differs
The overall index consists of food, non-food goods and services. In Rosstat tables for the first two groups it can be seen that in 2026 they diverged.
Food in 2026 became noticeably less expensive than usual. From the start of the year to September it rose by 2.80% compared to December 2025, and in April and May its prices fell: indices 99.80 and 99.15. By comparison, for the whole of 2025 food prices rose by 5.24%, and for 2024 by 11.05%.
Non-food goods, on the contrary, accelerated. From January to September 2026 they increased by 5.24%, whereas for the whole of 2025 it was only 2.99%. In June the index was 101.00, in July 101.26: noticeably higher than the usual 100.3‑100.6 for this group in 2025.
Data on services are not presented as a separate set in this issue, so the overall inflation of 2026 cannot be broken down into three parts by month using a single table. The basket structure and group weights were explained in the article about the consumer price index.
