Stock Average Price Calculator
Calculate average share price after a new purchase. Free stock average calculator with quantity, buy price, charges and total invested.
यहाँ से शुरू करें
- क्या भरें
- पुराने शेयरों की संख्या और औसत लागत, फिर नई खरीद की संख्या, कीमत और कुल शुल्क भरें।
- नतीजे का मतलब
- नया औसत = कुल खरीद लागत ÷ कुल शेयर; यह आज का बाजार भाव नहीं है।
उदाहरण और सीमाएँ देखें
- आसान उदाहरण
- 10 शेयर ₹100 पर और 10 ₹80 पर, नए शुल्क ₹0 हों तो 20 शेयरों की औसत लागत ₹90 है।
- ध्यान रखें
- पुराने शुल्क औसत में और नए शुल्क अलग खाने में जोड़ें। बिक्री और कॉर्पोरेट बदलाव का हिसाब नहीं है; औसत घटने से शेयर सुरक्षित नहीं होता।

Purchase details
- New average
- ₹473.67
- Total quantity
- 150
- Total invested
- ₹71,050
- Average change
- -5.3%
आपके आँकड़ों का मतलब
Your average drops 5.3% to ₹473.67.
The whole holding now breaks even at ₹473.67 instead of ₹500.00.
The stock must rise 12.8% from ₹420.00 for you to break even.
Your average cost including charges is ₹473.67; above that, the whole position is in profit.
Charges add ₹1.00 to each new share.
That's 0.24% of this purchase, small enough not to move your average much.
अपनी गणना समझें
The stock average price calculator works out your new average buy price after adding more shares to an existing position. Enter your existing quantity and average price, then the new quantity, price and charges. It shows the combined quantity, total amount invested, the updated average price per share and how far that average has moved from your old one.
Stock Average Price Calculator क्यों उपयोग करें
Averaging down or averaging up changes your cost basis, and the mental maths gets messy once brokerage, exchange charges and taxes on the trade are added. This calculator keeps the cost basis transparent before you place another order. It's useful for long-term investors adding to a holding, traders tracking position size, and anyone who wants to know the break-even price after a few purchases at different levels.

उदाहरण
Averaging down from ₹500 to about ₹474
You own 100 shares bought at an average of ₹500, so your existing cost is ₹50,000. You buy 50 more at ₹420 and pay ₹50 in charges, so the new purchase costs 50 × ₹420 + ₹50 = ₹21,050. Total cost is ₹71,050 for 150 shares, and ₹71,050 ÷ 150 = ₹473.67 per share.
- Old holding
- 100 shares at ₹500 (₹50,000)
- New buy
- 50 shares at ₹420 + ₹50 charges (₹21,050)
- Total quantity
- 150 shares
- Total invested
- ₹71,050
- New average price
- ₹473.67
- Change in average
- −5.27%
Buying 50% more shares moved the average down by only about 5%. The share now needs to reach ₹473.67, not ₹420, for the whole position to break even before selling costs.
इसकी गणना कैसे होती है
The calculator takes a quantity-weighted average: new average = (old quantity × old average + new quantity × new price + charges) ÷ (old quantity + new quantity). The numerator is the total invested and the denominator is the total quantity.
Charges are added to the cost of the new purchase only, because your old average should already include what you paid the first time. The change in average is (new average − old average) ÷ old average, shown as a percentage, and is zero when there's no existing average to compare with.
If the total quantity is zero, the average shows as zero. The result is a simple average cost, not a tax-lot calculation.
मान्यताएँ और सीमाएँ
- The calculator uses purchase cost only and does not model tax lots or the order in which shares are sold.
- Brokerage and charges are added to the new purchase cost.
- It does not recommend whether averaging is suitable for a specific stock.
अक्सर पूछे जाने वाले प्रश्न
Does averaging down reduce my loss?
It reduces the average cost per share, but it also increases exposure to the same stock. If the price keeps falling, the rupee loss grows faster because you now hold more shares.
Should charges be included in average price?
Yes. Charges are part of the acquisition cost and including them gives a more accurate cost basis and break-even price.
Can I use this for mutual funds?
Yes, the same weighted average logic works for units of mutual funds and ETFs. For a mutual fund, use units for quantity and the NAV you bought at for price.
Does this calculate capital gains tax?
No. Use the capital gains calculator separately because tax depends on sale price, holding period and asset type. For tax, each purchase also keeps its own date, so the average price alone isn't enough.
How do I average more than two purchases?
Run it in steps. Enter the first two purchases, note the new quantity and average, then enter those as the existing holding and add the third purchase. The result is the same as averaging all of them at once.
Why is my broker's average different from this result?
Brokers may exclude some charges from the displayed average, or adjust it after partial sales, bonuses or splits. Check which charges your broker includes, and enter the same figures here if you want the numbers to match.
अंतिम बात
Use the stock average price calculator before increasing a position. It gives a clean view of your new cost basis and total exposure, which is more useful than looking only at the lower purchase price. If the averaging move would make one stock an outsized part of your portfolio, check your overall allocation before placing the order.
