How this is calculated
New average = (shares held × old average + new shares × buy price) ÷ total shares. Shares needed for a target = held × (old average − target) ÷ (target − buy price), when the buy price is below the target.
What the letters mean: q1, p1 = shares and average you hold; q2, p2 = shares and price you buy now; target = the average you want.
Timing: Prices only; brokerage and taxes are not included (use the Brokerage calculator).
Default values: Shares you hold: 100 qty · Your average price: ₹500 · Shares you will buy: 50 qty · Buy price now: ₹400 · Target average price: ₹450
