Consumer Food Price Index

Also called: CFPI · Topic: Inflation and Index Numbers: CPI, WPI, IIP and the Deflator · NCERT: Class 11, Ch 7 "Index Numbers"

Meaning

The Consumer Food Price Index (CFPI) is a price index for food alone. The NSO (National Statistics Office, under MoSPI) compiles it separately for rural, urban and combined India. In the 2012 series, it covered the CPI's "food and beverages" group, minus non-alcoholic beverages and minus prepared meals, snacks and sweets.

The year-on-year change in the CFPI is what India calls food inflation. Food takes the biggest share of a poor family's budget, so the CFPI shows how rising prices hit ordinary households. It also shows how much food pushes up the headline inflation number that the RBI targets.

Formula (food inflation): Food inflation (%) = (CFPIₜ − CFPIₜ₋₁₂) ÷ CFPIₜ₋₁₂ × 100 Here CFPIₜ is this month's index and CFPIₜ₋₁₂ is the index for the same month last year.

Explanation

How the CFPI is built

• The CFPI is a sub-index (a smaller index built from one part) of the Consumer Price Index (CPI). The CPI is a cost-of-living index that uses retail prices, the prices people pay in shops.
• It uses the same method as the full CPI:
• It takes a fixed basket of food items that households usually buy.
• Each item gets a weight, which is its share of the family budget. Weights come from household consumption expenditure surveys.

• The index compares what the basket costs today with what it cost in the base year (the year when the index = 100).

• The official method works at two levels [2]:

• Jevons index (a geometric mean of price relatives) for single items across many markets.

• Young / modified Laspeyres index (a weighted average that uses base-period weights) to combine items into bigger groups such as food.

• The NCERT family budget method is the same weighted-average idea: CPI = ΣWR ÷ ΣW, where R = (p₁ ÷ p₀) × 100 is an item's price relative and W is its weight.

What it includes and leaves out

• Included: the "food and beverages" group of the CPI, such as cereals, pulses, vegetables, fruit, milk, meat, oils and spices.
• Excluded:
• Non-alcoholic beverages such as tea, coffee and soft drinks.

• Prepared meals, snacks and sweets, meaning cooked food bought from outside.

• Common trap: NCERT says "alcoholic beverages". That is wrong. Alcoholic beverages sit in the pan, tobacco and intoxicants group, not in food.

• The CFPI's weight in the 2012 CPI-Combined was about 39. That is lower than the full food and beverages group (45.86) because of the items left out.

Worked example: how heavy food is (NCERT Class 11, Index Numbers, Q18)

• Given: CPI = 125, food index = 120, index for all other items = 135. Let food's weight = w.
• 120w + 135(1 − w) = 125
• 135 − 15w = 125 → w = 2/3
• So food carries about 66.7% of this worker's basket. When food prices move, the whole cost of living moves with them.

What makes the CFPI rise or fall

• Supply shocks. A bad monsoon, a heatwave or crop damage means less food reaches the market, so prices jump.
• Vegetables such as onion, tomato and potato are perishable and cannot be stored for long.

• So their prices swing sharply, and the CFPI swings with them.

• Good harvests and falling vegetable prices pull the CFPI down.

• Example, January 2026: garlic (−53%), onion (−29%) and potato (−29%) pulled food inflation down [3].

• Other factors: transport and fuel costs, traders' margins, import and export rules, and minimum support prices.

In India

• Compiler: the NSO (MoSPI) compiles the CFPI for rural, urban and combined India, together with CPI-Rural, CPI-Urban and CPI-Combined. The Labour Bureau compiles CPI-IW, CPI-AL and CPI-RL, not the CFPI.
• New base 2024=100: the new CPI series was first released on 12 February 2026. Its weights come from HCES 2023-24 (Household Consumption Expenditure Survey) [3].
• Latest food inflation, January 2026 (2024 base): 2.13% combined, 1.96% rural and 2.44% urban [3].
• Headline CPI-C inflation in the same month was 2.75% [3].

• Food inflation was below headline inflation, so food pulled overall inflation down that month.

• Food's weight is falling:

• Food and beverages in CPI-C fell from 45.86 (2012) to 40.10 (2024) in the old 6-group structure [2].
• Under the new COICOP 2018 structure (the UN's Classification of Individual Consumption According to Purpose), the "Food and beverages" division weighs 36.75 in 2024. The comparable 2012 figure would be 42.62 [2].
• Rural food weight fell from 54.18 → 44.80 and urban from 36.29 → 34.26 [2].

• The reason is Engel's law: as incomes rise, families spend a smaller share of their budget on food.

• Link to monetary policy: under Section 45ZA of the RBI Act, 1934, the Central Government, in consultation with the RBI, has set the target at 4% CPI-C inflation, ±2 percentage points [4]. Food is the largest part of CPI-C, so the CFPI strongly shapes whether the RBI meets this target.

• Free ration grain is not counted. The CPI counts only what households actually pay [2]. Free PDS grain therefore does not enter the food index.

Don't confuse with

• "Food and beverages" group of the CPI: this group is wider than the CFPI. It also includes non-alcoholic beverages and prepared meals, snacks and sweets. In the 2012 CPI-C, food and beverages weighed 45.86, while the CFPI weighed about 39.
• Headline CPI inflation (CPI-C): this covers all items, including food, fuel, housing and services, and it is the RBI's target. The CFPI covers food only.
• Core inflation: this is inflation with food and fuel removed. The CFPI is the food part that core inflation leaves out.
• WPI food index: the WPI uses wholesale prices (prices in bulk trade between producers and traders). The CFPI uses retail prices, which include traders' margins and transport costs. So the two can move differently.

Prelims Hooks

• CFPI is compiled by the NSO (MoSPI), not the Labour Bureau. It is released for rural, urban and combined India.
• CFPI = food and beverages group − non-alcoholic beverages − prepared meals, snacks and sweets. Alcoholic beverages sit in pan, tobacco and intoxicants, not in food.
• Food inflation = year-on-year % change in the CFPI. In January 2026 it was 2.13% combined, compared with 2.75% headline CPI-C [3].
• Food and beverages weight in CPI-C: 45.86 (2012) → 40.10 (2024, old structure) / 36.75 (2024, COICOP 2018) [2]. The CFPI's own weight in the 2012 CPI-C was about 39.
• New CPI base 2024=100, first released on 12 February 2026, with weights from HCES 2023-24 [3].
• Trap: "The RBI targets food inflation." This is false. The RBI targets CPI-Combined inflation at 4% ± 2% under Section 45ZA [4].

Mains Points

• Headline vs core targeting (GS-III):
• Food inflation is mostly supply-driven, from monsoons, heatwaves and crop damage.
• Raising the repo rate (the rate at which the RBI lends money to banks for a short time) cannot grow more onions. So some experts argue for targeting core inflation.
• But food prices shape what households expect prices to do next, so removing food from the target is risky.

• The RBI's Discussion Paper on Review of the Monetary Policy Framework (21 August 2025) takes up exactly this question [5].

• Rebasing changes food's pull on headline inflation (GS-III):

• In the 2012 series, food and beverages weighed about 46%. Onion, tomato or pulses shocks therefore pushed up headline inflation more than today's spending justifies.
• The 2024 series cuts food's weight to 40.10 / 36.75 and adds services and rural housing [2]. Headline inflation now tracks real household budgets more closely.

• But food is still the largest group, and it weighs much more in rural baskets (44.80) [2]. Food supply management still matters: storage, cold chains, buffer stocks and trade policy.

• Food inflation and welfare (GS-II):

• Poor families spend the largest share of their income on food, so food inflation works like a regressive tax (it hits the poor hardest).
• The CPI excludes free PDS grain [2]. The CFPI shows market prices, not the relief households get from free rations.
• Keep this in mind when the CFPI is used to judge real wages, poverty or how well food security schemes work.
