DCA Calculator

How to Use This Tool

Choose an asset from 20 supported instruments - including Bitcoin, Ethereum, Apple, NVIDIA, the S&P 500 ETFs (VOO, SPY), and gold - then enter your periodic investment amount, the frequency (daily, weekly or monthly), and the date range. The calculator pulls real daily closing prices and simulates every single purchase on its due date.

• Full investment simulation - Every purchase is executed at that day price, with running units and invested totals.
• DCA vs lump sum - Compare your periodic investing result with investing the same total amount on day one.
• Best and worst months - See which months delivered the biggest gains and losses for the asset in your window.
• Value-over-time chart - Visualize your portfolio value climbing against the total amount invested.
• Monthly breakdown table - Every purchase: date, price, amount, units bought, total units and total invested.
• 30+ currencies - All results convert into your local currency with live exchange rates.

Understanding the Numbers

The simulation invests the same amount on every scheduled date using that day closing price. Total units = sum of amount / price per purchase; current value = total units x the latest price in the range. ROI = (current value - total invested) / total invested. The lump sum comparison invests the full amount once, on the start date, and holds until the end of the range.
