2. Summary charts for price indices
Figure 1: Monthly price indices for agricultural outputs and inputs to August 2022 (2015 = 100)
Figure 1 shows the monthly price indices for agricultural outputs and inputs during the previous 6 years (August 2016 to August 2022). Overall, the price index for agricultural outputs tends to be more volatile than that for agricultural inputs, though considerable volatility has been observed in both outputs and inputs in recent times. The price index for agricultural inputs decreased for the first time this month since June 2020, halting a trend of steep increases. For agricultural outputs, August 2022 is the second consecutive month for which prices have decreases, following significant price increases in the first half of 2022.
Figure 2: Annual average price indices for agricultural outputs and inputs to August 2022 (2015 = 100)
Figure 2 shows the annual average price indices for agricultural outputs and agricultural inputs since 2015. In 2022 (to date), the annual average price index is 16.7% higher for agricultural outputs and 24.8% higher for agricultural inputs compared to 2021. The year with the largest difference between the agricultural outputs and agricultural inputs remains 2017, with 2020 showing the second largest difference.

4. Contributions to the annual agricultural outputs and inputs inflation rate
Figure 5: Contributions to the 12-month inflation rate in agricultural outputs (21.0%), UK, August 2021 to August 2022
Figure 5 shows the extent to which different agricultural commodity categories have contributed to the 12-month inflation rate for agricultural outputs over the last year. The inflation rate for agricultural outputs has fluctuated between 6.4% and 21.0% since August 2021, with the main contributors varying for different months. Most recently, the 12-month inflation rate in August 2022 saw upward contributions from three of the four output categories, namely livestock and animal products, cereals, and industrial and other crops.
Figure 6: Contributions to the 12-month inflation rate in agricultural inputs (30.7%), UK, August 2021 to August 2022
Figure 6 shows the extent to which different agricultural input categories have contributed to the 12-month inflation rate for agricultural inputs over the last year. The inflation rate for agricultural inputs decreased by 0.9 percentage points on the previous month in August 2022, following substantial increases throughout the year as a result of higher prices across all farm input categories. The increasing cost of natural gas prices has severely impacted the fertiliser industry. With domestic production greatly reduced from September 2021, the price of fertilisers has increased considerably. For example, ammonium nitrate was over twice as expensive in August 2022 than in August 2021. Fuel prices have also risen substantially since August 2021 though are now beginning to decrease.

About these statistics
Background
The output series reflects the price farmers receive for their products, also referred to as farm gate price. Information is collected for all major crops (for example wheat and potatoes) and livestock and animal products (for example sheep, milk and eggs).
The input series reflects the price farmers pay for goods and services. The series is in two groups: goods and services currently consumed; and goods and services contributing to investment. Goods and services currently consumed refer to items that are used up in the production process, for example fertiliser or seed. Goods and services contributing to investment relate to items that are required but not consumed in the production process, such as tractors or buildings.
Data uses
Farmers use the Agricultural Price Index to help set prices for their outputs and monitor the prices paid for inputs. Analysts in Government, industry specialists, consultants, economists and academics use the data to assess the impact that price changes have on industry and consumers.
The Office of National Statistics (ONS) uses API data in the production of the Producer Price Index (PPI), which is one of the key measures of inflation.
Methodology
Price data
Defra collect prices from a wide variety of sources to produce the monthly API. This includes data from our own surveys, information from the Horticultural Marketing Inspectorate (HMI), Agricultural and Horticultural Development Board (AHDB), and the ONS. For some items we only receive quarterly or annual data, for example, electricity prices. When no new data are available estimates are made based on previous values until new data becomes available. When new data become available, historical revisions are made and a note is added in the ‘What you need to know about this release’ section.
In order to maintain continuity in these statistics, the Agricultural Price Index is produced in accordance with the European Statistical System.
Weights
Each price point is assigned a weight which reflects its contribution to the overall index. The weights for each item represent their annual monetary value from the Agricultural Accounts. For example, if the annual value of animal feed purchased is three times more than fertilisers then the annual weight for animal feed will also be three times more than for fertiliser. Where monthly data is available, monthly and quarterly weights for outputs reflect the pattern of sales volumes across the year. For example, if the volume of sales for apples in October is double that in June, then the October weight for apples is double the weight for June. Monthly and quarterly weights for input items do not vary within the year. The weights are recalculated every five years to reflect more recent data. The April 2018 index was the first to be produced using weights based on 2015, replacing weights based on 2010.
Contributions
It is often of interest to estimate the effect of a group or item on the change in the agricultural outputs or inputs index. The contribution of a group or item to a change in the all items index over a given period of time is defined as the change that would have occurred in the all items index if that component had undergone its observed change but all other component indices had remained frozen at their values at the start of the period (and all weights are kept the same). The effect of each component depends on both the size of its change and its weight.
The formula for calculating the contributions to changes in the agricultural inputs inflation rate differs from the agricultural outputs inflation rate, reflecting the fact that monthly and quarterly weights for input items do not vary within the year. The formulas for calculating contributions to changes in all items index with seasonal and non-seasonal weights can be found in the 2007 Technical Manual on Consumer Price Indices published by the ONS.
The categories shown in Figures 5 and 6 were created by aggregating the following categories:
-
Fresh fruit, fresh vegetables, flowers and plants, and potatoes into horticulture.
-
Industrial crops, forage plants and other crop products into industrial and other crops.
-
Fertilisers and soil improvers, plant protection products and seeds into crop-related costs.
-
Animal feedingstuffs and veterinary services into livestock-related costs.
-
Maintenance of buildings, maintenance of materials, other goods and services, buildings and materials into other farm costs.
