Frequently asked questions
Does the calculator work for stocks and crypto?
Yes. The math is the same for stocks, crypto, ETFs, index funds, goods, or any asset bought in different quantities.
Does the result include fees?
No. To include brokerage fees, add those costs to the total amount invested before calculating the average price.
Is average price investment advice?
No. This tool only calculates numbers you enter and does not replace professional financial advice.
How do I calculate average price manually?
Multiply each quantity by the purchase price and sum all results. Then divide by the total number of units. Example: (10 × $20) + (5 × $26) = $330 ÷ 15 = $22.
What is DCA and how does this help?
Dollar cost averaging (DCA) means buying an asset at regular intervals to reduce the impact of price swings. This calculator tracks each purchase so you always know your current cost basis.
Does buying at a lower price reduce my average?
Yes. If you hold shares at $30 and buy more at $20, the new average falls between those two prices, lowering your break-even point.
