Example 1: Tata Motors Ltd

Let’s consider an investor who purchases Tata Motors Ltd shares on three different occasions:

First Purchase:

  • Price per share: ₹200
  • Number of shares: 100
  • Total cost: ₹200 * 100 = ₹20,000

Second Purchase:

  • Price per share: ₹220
  • Number of shares: 50
  • Total cost: ₹220 * 50 = ₹11,000

Third Purchase:

  • Price per share: ₹210
  • Number of shares: 75
  • Total cost: ₹210 * 75 = ₹15,750

Total Calculation:

  • Total Cost: ₹20,000 + ₹11,000 + ₹15,750 = ₹46,750
  • Total Shares: 100 + 50 + 75 = 225

Average Price per Share:

  • Calculation: ₹46,750 / 225 = ₹207.78

Example 2: Infosys

Now, let’s look at an example with Infosys shares:

First Purchase:

  • Price per share: ₹1,500
  • Number of shares: 30
  • Total cost: ₹1,500 * 30 = ₹45,000

Second Purchase:

  • Price per share: ₹1,550
  • Number of shares: 20
  • Total cost: ₹1,550 * 20 = ₹31,000

Total Calculation:

  • Total Cost: ₹45,000 + ₹31,000 = ₹76,000
  • Total Shares: 30 + 20 = 50

Average Price per Share:

  • Calculation: ₹76,000 / 50 = ₹1,520

Example 3: Wipro

Lastly, consider an investor purchasing Wipro shares:

First Purchase:

  • Price per share: ₹300
  • Number of shares: 200
  • Total cost: ₹300 * 200 = ₹60,000

Second Purchase:

  • Price per share: ₹310
  • Number of shares: 150
  • Total cost: ₹310 * 150 = ₹46,500

Third Purchase:

  • Price per share: ₹290
  • Number of shares: 100
  • Total cost: ₹290 * 100 = ₹29,000

Total Calculation:

  • Total Cost: ₹60,000 + ₹46,500 + ₹29,000 = ₹135,500
  • Total Shares: 200 + 150 + 100 = 450

Average Price per Share:

  • Calculation: ₹135,500 / 450 = ₹301.11
