What it is
The dollar-cost averaging (DCA) calculator simulates purchasing a fixed monetary amount of an asset at regular intervals over time, showing total investment, units accumulated, average cost, and final portfolio value.
Why it matters
DCA removes emotional timing from investing by buying more units when prices are low and fewer when prices are high, lowering overall average cost during downturns.
Why traders use it
Long-term investors and crypto accumulators use it to model periodic accumulation strategies.
How important is it?
Great for steady wealth building in volatile assets, though it does not eliminate downside risk in permanent bear markets.
Worked example
With $100 per purchase across 12 purchases, starting price $100 and ending price $80: total invested is $1,200, average cost is calculated based on linear interpolation, and final value reflects the ending price.
Common mistakes
- Applying DCA blindly to fundamentally broken projects that continue heading to zero.
- Stopping accumulation out of panic during deep market dips.
Frequently asked questions
Why is my DCA average cost lower than the simple average of the start and end price?
Because investing a fixed dollar amount buys more units when the price is lower and fewer units when the price is higher, pulling your weighted average cost down (harmonic mean effect).
Is DCA better than lump-sum investing in crypto?
Lump-sum outperforms in strong uptrends, but DCA significantly reduces drawdown risk and regret during volatile sideways or bear market accumulation phases.
How often should I make DCA purchases?
Most investors align recurring buys with weekly or monthly paychecks to automate accumulation without paying excessive small-order fees.
