Crypto DCA Calculator

What this calculator actually shows you

Dollar-cost averaging means buying a fixed dollar amount on a fixed schedule. A hundred bucks of Bitcoin every Friday, rain or shine, whether the chart looks like a rocket or a cliff. Simple idea, endlessly debated.

I built this to settle the debate with data instead of vibes. Pick a coin, an amount, a frequency and a period, and it backtests the strategy against real daily prices from CoinGecko: what you’d have invested, what it’s worth today, your average cost per coin. And the number most calculators conveniently skip, which is how the same money would have done as one lump-sum buy on day one.

Why does that comparison matter? Because DCA isn’t magic, it’s a trade. Averaging in smooths volatility and kills the “is now a good time?” paralysis, which usually helps in falling or sideways markets. In a strong uptrend the lump sum wins, since every later purchase buys higher. Neither outcome is a verdict on you. It’s a property of the price path, and nobody knows the price path in advance. What DCA reliably buys is discipline and a defensible average cost, and for most people that behavioral edge is worth more than the optimization they gave up. Run a few periods and coins through the tool and you’ll see both cases play out in the real numbers.

Two honest limitations. The results exclude exchange fees, which typically run 0.1% to 1.5% per purchase depending on the platform, and recurring-buy features often charge the high end of that range. Compounded over a year of weekly buys, fees quietly eat a chunk of your edge. And past performance tells you what happened, not what will happen. Before setting up recurring buys anywhere, run the platform through my exchange red-flag checks and verify its license. Takes minutes, saves fortunes.

FAQ

Is DCA better than lump-sum investing in crypto?

Depends on the market you get. Lump-sum tends to win in sustained uptrends because the money is in the market longer, while DCA wins in declining or choppy markets by lowering your average cost. DCA’s real advantage is behavioral: it removes timing decisions and keeps you consistent through volatility.

How often should I DCA: daily, weekly, or monthly?

Over meaningful periods, the return difference between daily, weekly and monthly DCA is usually small. Fees matter more. Many platforms charge higher fees on small recurring buys, so fewer, larger purchases often net out better than daily ones. Pick the rhythm you’ll actually stick to.

Does this calculator include fees and taxes?

No. Results are gross of fees and taxes to keep comparisons clean across platforms. Real returns will be lower depending on your exchange’s fee structure and your local tax rules. In some jurisdictions each purchase is also a taxable event worth tracking.

Where does the price data come from?

Live daily historical prices from CoinGecko’s public API, in USD, covering up to the last 12 months. If the calculator shows an error, CoinGecko’s free rate limit was probably hit. Wait half a minute and try again.
