What is dollar-cost averaging (DCA)?

An investing strategy of investing a fixed dollar amount at regular intervals regardless of price, which naturally buys more units when the price is low and fewer when it's high — smoothing out the average cost per unit over time compared to a single lump-sum purchase.

Does DCA guarantee a profit?

No — DCA does not guarantee a profit or protect against loss in a sustained declining market. If an asset's price keeps falling and never recovers, DCA simply results in a lower average cost, not a guaranteed positive return.

Why would I use a negative trend assumption?

To see how a declining-price scenario affects average cost and ending value — useful for understanding DCA's behavior in a downturn, though it's a hypothetical assumption, not a prediction that prices will actually decline.

Can I model a real historical crypto price crash or rally with this?

Only approximately, by manually setting a starting price and a constant trend rate that roughly matches a period you're curious about — this tool doesn't import real historical price data, so it can't replay an actual historical scenario exactly.

Is crypto DCA the same as DCA into stocks or index funds?

The mechanics are identical — this tool works the same way for any asset with a price per unit. Crypto is simply far more volatile than most traditional assets, which is often cited as a reason DCA is popular for it specifically.

About the Crypto DCA Calculator

Simulates a hypothetical dollar-cost-averaging (DCA) investing scenario for a volatile asset like crypto — investing a fixed amount at a set frequency against a starting price and an assumed constant price trend — to illustrate the mechanics of DCA, not to forecast or backtest real market performance.

How to use it

Enter the amount you'd invest per period and how often (weekly, biweekly, monthly).
Enter the number of periods to simulate and a starting price per unit.
Enter an assumed price trend per period (can be negative, for a declining-price scenario).
Read the estimated ending value, total invested, and average cost per unit.

Formula

For each period i (0-indexed): price = starting price × (1 + trend)^i. Units bought that period = investment amount ÷ that period's price. Total units = sum of all periods' units. Total invested = investment amount × number of periods. Average cost per unit = total invested ÷ total units. Ending value = total units × the final period's price.

Worked example

Investing $100 monthly for 12 periods starting at $50,000/unit with a 0% assumed trend (flat price): 12 equal purchases at the same price, so average cost per unit exactly equals the starting price and ending value exactly equals total invested — a useful baseline before adding a nonzero trend assumption.

Interpreting your result

This has no live or historical crypto price feed — prices are entirely generated from a starting price and a constant assumed trend rate you supply, not real market data. Dollar-cost averaging does not guarantee a profit or protect against loss in a declining market, and crypto assets are highly volatile and speculative. Treat every result here as a 'what if prices moved this way' illustration of DCA mechanics, not a forecast, backtest, or investment recommendation.

Recommendations

• Try a 0% trend first to see the baseline (DCA with a flat price simply produces average cost = starting price, since every purchase happens at the same price).
• A negative trend (declining price) actually lowers your average cost per unit over time, since each period's fixed dollar amount buys more units at a lower price — the classic argument for DCA smoothing out volatility, though it says nothing about whether the asset's price will actually decline.
• This tool cannot and does not predict real crypto prices — use it only to understand how DCA mechanics respond to a price path you specify, not as an investment forecast.

Frequently asked questions

No — it has no live or historical price feed at all. You supply a starting price and an assumed constant trend rate, and the tool generates a purely hypothetical price path from those two inputs.
