Crypto DCA Calculator
This free crypto DCA calculator shows how a dollar-cost averaging plan adds up over time. Enter how much you invest each time, how many purchases you make, your estimated average buy price, and the current price, and it works out your total invested, the coins you accumulated, today's value, and your return. Everything runs in your browser, so nothing you type is saved or sent anywhere.
How to Use the DCA Calculator
The calculator needs four numbers. Enter the amount you invest each time in US dollars, the number of purchases you have made or plan to make, your average buy price per coin, and the current price per coin. Press Calculate or the Enter key and the results appear instantly. Because you supply a fixed dollar amount and a purchase count, you do not need to add up every buy by hand: the tool multiplies them for you and shows your total invested at the top of the results.
One point matters most here. This tool uses your estimate of the average price you paid across all your buys; it does not fetch historical prices for you. If you have your real average cost basis from your exchange, enter that for the most accurate result. If you are planning ahead, use a reasonable estimate of where you expect prices to sit while you accumulate.
The Formula Behind It
The math is simple arithmetic you can check by hand:
- Total invested = amount per purchase × number of purchases
- Coins accumulated = total invested / average buy price
- Current value = coins accumulated × current price
- Profit / loss = current value − total invested
- ROI = profit / total invested × 100
If the current price is above your average buy price, you show a gain; if it is below, you show a loss. That is the whole logic of a dollar-cost averaging plan measured at a single point in time.
A Worked Example
Say you invest $100 per purchase across 12 purchases. Your total invested is $1,200. If your average buy price across those 12 buys was $30,000 per coin, you accumulated 0.04 coins. If the current price is $45,000, that 0.04 coins is worth $1,800 today. Your profit is $1,800 minus $1,200, or $600, which is a 50% return on what you put in. Change the current price to something below $30,000 and you will see the same plan turn into a loss, which is a useful reminder that DCA manages timing risk but does not remove market risk.
Why Dollar-Cost Averaging Works
Dollar-cost averaging means investing a fixed amount at regular intervals instead of trying to time one perfect entry. Because you spend the same dollars each time, you automatically buy more coins when prices are low and fewer when prices are high, which smooths out your average cost. That removes the pressure of guessing the bottom and protects you from putting your whole stake in right before a drop. It also builds a habit: a steady schedule is far easier to stick to than watching charts and reacting emotionally.

Limitations to Keep in Mind
- It can underperform lump-sum in a straight bull run. If the price only rises, investing everything at the start would have bought more coins earlier. DCA trades some upside for lower timing risk.
- It requires discipline. The strategy only works if you actually keep buying on schedule, including during scary drops when it feels wrong.
- This tool uses your estimate. It does not pull historical prices, so the result is only as accurate as the average buy price you enter.
- It shows pre-tax, pre-fee results. Real returns may be lower after trading costs and any taxes that apply where you live.

Frequently Asked Questions
How does a DCA calculator work?
A DCA calculator estimates how a dollar-cost averaging plan turns out. It multiplies the amount you invest each time by the number of purchases to get your total invested, divides that by your average buy price to find how many coins you accumulated, then multiplies the coins by the current price to get today's value. Subtracting your total invested gives your profit or loss, and dividing that by the total invested gives your return.
What is dollar-cost averaging?
Dollar-cost averaging (DCA) is investing a fixed amount of money at regular intervals, such as $100 every week or every month, regardless of the price. Because you buy the same dollar amount each time, you automatically buy more coins when the price is low and fewer when it is high. This spreads your entry across many prices instead of betting everything on a single moment.
Does DCA guarantee a profit?
No. Dollar-cost averaging reduces the risk of buying everything at a bad moment, but it does not guarantee a profit. If the price of the asset is lower when you check your plan than the average you paid, you will show a loss. DCA is a way to manage timing risk and stay disciplined, not a promise of returns. Nothing here is financial advice.
Is my data saved or sent anywhere?
No. This calculator runs entirely in your browser using JavaScript. Nothing you type is saved, tracked, or sent to any server. When you close the tab, the numbers are gone. That matches CustomCrypto's privacy-first approach: your data stays on your device.
