The Agricultural Price Index (API) is an index of the price of agricultural outputs and inputs for the UK used to track change over time. More details on the index, including how it is produced, are in the Background section at the end of this document.
1. Key points at May 2023
Outputs
- The price index for agricultural outputs increased by 0.2% in the 12 months to May 2023.
- There were 8 upward contributions to the 12-month inflation rate for agricultural outputs recorded for May 2023. The largest upward contribution was potatoes (+1.7 percentage points), followed by cattle and calves (+1.7 percentage points), fresh vegetables (+1.5 percentage points), and fresh fruit (+1.5 percentage points).

2. Summary charts for price indices
Figure 1: Monthly price indices for agricultural outputs and inputs to May 2023 (2020 = 100)
Figure 1 shows the monthly price indices for agricultural outputs and inputs since January 2020. The two indices were closely aligned throughout 2020 and much of 2021, before agricultural inputs saw considerably higher rates of inflation as prices of key inputs (particularly fertiliser and animal feed) experienced rapid price increases. Following this, the agricultural inputs index saw a period of price stabilisation while the agricultural outputs index continued to rise, peaking later in 2022. The two indices have seen month-on-month declines so far in 2023.
Figure 2: Annual average price indices for agricultural outputs and inputs to May 2023 (2020 = 100)
Figure 2 shows the annual average price indices for agricultural outputs and agricultural inputs since 2020. In 2023 (to date), the annual average price index is 4.6% higher for agricultural outputs and 0.3% lower for agricultural inputs compared with 2022. The annual price indices for inputs have consistently been higher than those for outputs since 2020, with the gap between the two series being widest in 2022.
| Year | All agricultural outputs | All agricultural inputs |
|---|---|---|
| 2020 | 100.0 | 100.0 |
| 2021 | 109.9 | 111.4 |
| 2022 | 130.6 | 143.2 |
| 2023 | 136.7 | 142.8 |
3. Contributions to the annual agricultural outputs and inputs inflation rates

4. Contributions to the annual agricultural outputs and inputs inflation rate
Figure 5: Contributions to the 12-month inflation rate in agricultural outputs, UK, May 2022 to May 2023
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 +0.2% and +23.8% since May 2022. Most recently, the 12-month inflation rate saw upward contributions from livestock and animal products and horticulture, and downward contributions from cereals and industrial and other crops.
Figure 6: Contributions to the 12-month inflation rate in agricultural inputs, UK, May 2022 to May 2023
Figure 6 shows the extent to which different agricultural inputs have contributed to the 12-month inflation rate for agricultural inputs over the last year. The inflation rate for inputs has fallen considerably in the last 8 months amid large falls in the prices of key inputs, including fertilisers. Significant falls in wholesale gas prices have made way for these downward price movements. The inflation rate for agricultural inputs has fluctuated between -6.1% and +35.3% since May 2022, with the main contributors varying for different months. Most recently, the 12-month inflation rate saw downward contributions from all input categories except other farm costs.

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 March 2023 index was the first to be produced using weights based on 2020, replacing weights based on 2015.
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 Figure 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.
