Crypto DCA Calculator

Enter each cryptocurrency purchase amount and its price, then add a manual current or target price. The calculator combines all purchases into a volume-weighted average price without using a live cryptocurrency API.

What this calculator does

Combines multiple manually entered cryptocurrency purchases. For every row, the purchase amount is divided by its price to determine the quantity acquired. Those quantities are added together, and the total money invested is divided by the total cryptocurrency purchased to produce a quantity-weighted average purchase price. A manually entered current or target price is then used to estimate portfolio value, profit or loss, and ROI.

How to interpret the result

The average purchase price is the most useful starting point: it tells you the effective price paid per unit based on all the purchases entered. Compare that figure with the current or target price. If the target price is above the average purchase price, the position has a positive gross result before any fees or other costs; if it is below, the result is negative. The portfolio value and ROI show the same relationship in money and percentage terms.

Assumptions

• Each purchase amount represents the money used to acquire cryptocurrency before any separate fees.
• Each purchase price is the price per coin for that transaction.
• All purchase rows refer to the same cryptocurrency and the same unit of account.
• The current or target price is a manually entered scenario price.

Limitations

• Trading, network, withdrawal, tax, and other transaction costs are not automatically deducted.
• The calculator does not connect to an exchange and does not retrieve a live price.
• Transfers, staking rewards, airdrops, partial sales, and changes in the quantity held are outside the simple DCA model.

Useful for

• Reviewing a series of purchases made at different cryptocurrency prices.
• Testing what a DCA position would be worth at several manual target prices.
• Understanding the difference between a simple average of prices and the quantity-weighted average actually paid.

Why DCA needs more than an average of prices

When purchases have different amounts, simply adding the prices and dividing by the number of purchases can give the wrong impression of your average entry. A $50 purchase and a $500 purchase should not have the same influence on the result. The DCA calculator instead converts every purchase into cryptocurrency received and then divides total money invested by total cryptocurrency purchased. This is a quantity-weighted calculation, so larger purchases naturally have more influence on the average price.

Enter the purchase amount and price from each transaction

For each DCA row, enter the amount of money used and the price per coin at the time of purchase. If you bought $100 of a coin at $1,000, the calculation treats that as 0.10 coins before fees. If a later $200 purchase happened at $800, it adds another 0.25 coins. The calculator does not assume that every purchase was the same size, and it does not assume that the price followed a particular pattern between transactions.

Adding and removing rows keeps the model flexible

DCA histories often contain more than two or three purchases. The calculator lets you add rows as needed, which makes it possible to reproduce a longer purchase history without creating a separate calculation for every transaction. Removing a row immediately takes that purchase out of the calculation. This is also useful for scenario testing: you can temporarily remove a transaction to see how much it changes the average purchase price and the resulting portfolio value.

Use a manual target price for scenario testing

The current or target price is deliberately entered by you. That keeps the calculator independent of exchanges, APIs, API keys, and live market feeds. It also makes the tool useful for scenario analysis: enter one price, record the result, then test another. A target price is not a forecast produced by the calculator. It is simply the price assumption used to translate the cryptocurrency quantity into an estimated portfolio value.

Understand what the portfolio value represents

Portfolio value is calculated by multiplying the total cryptocurrency purchased by the current or target price you enter. Profit or loss is then the portfolio value minus total amount invested. This is a gross calculation because fees and other costs are not automatically deducted. If your transaction records show that fees reduced the amount of cryptocurrency you actually received, use the net quantity or otherwise account for those costs separately when you want a closer record-based comparison.

DCA does not remove market risk

Dollar-cost averaging changes how purchases are distributed over time; it does not guarantee a profit or prevent a portfolio from falling in value. If the target price is below the calculated average purchase price, the scenario produces a loss regardless of how many rows you entered. The calculator is therefore best used to understand the arithmetic of a purchase plan rather than as evidence that a particular asset or strategy will perform well.

Keep records for a more accurate real-world calculation

For an actual transaction history, use exchange statements or wallet records where possible. Keep the date, amount paid, quantity received, quoted price, fees, and any transfers that affect the balance. This calculator intentionally keeps the model simple enough to understand: amount, price, quantity, average price, and a manual target price. More complicated records may require additional accounting or tax calculations outside this tool.
