  • Simple Price Index

    Simple Price Index

    Definition

    Simple Price Index measures the change in price of a commodity in the current period compared to its price in a base period. It shows how much prices have increased or decreased over time.

    Formula

    Simple Price Index (SPI) = (Current Price ÷ Base Period Price) × 100

    Calculator

    SPI = 100 → No price change | SPI > 100 → Price increase | SPI < 100 → Price decrease

  • Laspeyres Price Index

    Laspeyres Price Index

    Definition

    Laspeyres Price Index measures the change in prices of a group of commodities over time by using quantities of the base period as weights. It shows how much more (or less) it would cost to purchase the base-period basket of goods at current prices.

    Formula

    Laspeyres Price Index (LPI) = ( Σ P1Q0 ÷ Σ P0Q0 ) × 100

    Where: P1 = current price, P0 = base price, Q0 = base period quantity

    Calculator (Single-Commodity Form)

    LPI > 100 → Price increase | LPI = 100 → No change | LPI < 100 → Price decrease

  • Paasche Price Index

    Paasche Price Index

    Definition

    Paasche Price Index measures the change in prices of a group of commodities over time by using quantities of the current period as weights. It shows how much it would cost to purchase the current-period basket of goods at current prices compared to base-period prices.

    Formula

    Paasche Price Index (PPI) = ( Σ P1Q1 ÷ Σ P0Q1 ) × 100

    Where: P1 = current price, P0 = base price, Q1 = current period quantity

    Calculator (Single-Commodity Form)

    PPI > 100 → Price increase | PPI = 100 → No change | PPI < 100 → Price decrease

  • Fisher’s Ideal Price Index

    Fisher’s Ideal Price Index

    Definition

    Fisher’s Ideal Price Index is a price index that measures the change in prices of a group of commodities over time by taking the geometric mean of the Laspeyres and Paasche price indices. It is called an ideal index because it satisfies both time reversal and factor reversal tests.

    Formula

    Fisher’s Ideal Index (F) = √(Laspeyres Price Index × Paasche Price Index)

    Where:
    Laspeyres = ( Σ P1Q0 ÷ Σ P0Q0 ) × 100
    Paasche = ( Σ P1Q1 ÷ Σ P0Q1 ) × 100

    Calculator (Single-Commodity Form)

    Fisher’s Index > 100 → Price increase | = 100 → No change | < 100 → Price decrease
