About the Stock Average Calculator
Averaging down means buying more shares of a stock you already own at a different price, which changes your average buy price. This calculator shows your new average and break-even price.
Enter the shares and price of your earlier and new purchases.
Formula used
Average price = (Quantity 1 × Price 1 + Quantity 2 × Price 2) ÷ (Quantity 1 + Quantity 2).
Frequently asked questions
Is averaging down a good idea?
Only if you still believe in the company. Buying more of a falling stock can increase your losses.
Does this include brokerage and taxes?
No. Charges raise your real break-even price slightly.
Can I use it for mutual funds?
Yes, with units and NAV instead of shares and price.
