Price Elasticity of Demand

PED = (%ΔQ) / (%ΔP)

Keterangan:

  • PED
    Price elasticity (absolute value)
  • Q
    Quantity demanded
  • P
    Price
  • %ΔQ
    Percentage change in quantity
  • %ΔP
    Percentage change in price

How to Use

  1. 1

    Input Harga & Kuantitas Awal

    Enter P1 and Q1.

  2. 2

    Input Harga & Kuantitas Akhir

    Enter P2 and Q2.

  3. 3

    Dapatkan nilai PED and interpretasi.

Contoh Perhitungan

Elastisitas Permintaan

Soal:

P1=10, Q1=100, P2=12, Q2=80. Cari PED?

Penyelesaian:
  1. 1.%ΔQ = (80-100)/100 × 100% = -20%
  2. 2.%ΔP = (12-10)/10 × 100% = 20%
  3. 3.PED = |-20/20| = 1
Hasil:PED = 1 (Unitary Elastic)

Permintaan merespons perubahan harga secara proporsional.

Pertanyaan yang Sering Diajukan (FAQ)

Apa arti PED > 1?
Elastis, permintaan very responsif terhadap perubahan harga.
Apa arti PED < 1?
