Calculadora de DCA e Lucro/Prejuízo
Calcule seu total investido, moedas acumuladas e lucro ou prejuízo de uma posição de dollar-cost averaging.
Dollar-cost averaging (DCA) significa investir um valor fixo em intervalos regulares em vez de tudo de uma vez, o que suaviza seu preço médio de entrada ao longo do tempo. Informe quanto você investe por período, quantos períodos já realizou, seu preço médio de entrada e o preço atual, e esta calculadora calcula seu total investido, moedas acumuladas, valor atual e lucro ou prejuízo.

Como funciona
Dollar-cost averaging (DCA) means investing a fixed amount at regular intervals — weekly or monthly, for example — rather than committing a lump sum all at once. Because you buy at whatever the price happens to be each time, your average entry price smooths out over the run, reducing the impact of buying right before a downturn (though it can also mean missing some of a rally). This calculator takes the amount you invest each period, how many periods you've run, your average entry price and today's price, and works out your total invested, how many coins that bought, what that position is worth today, and your profit or loss in both dollars and percent.
Exemplo prático
Suppose you've invested $200 a month for 12 months, at an average entry price of $40,000, and the coin now trades at $52,000. Total invested: $200 × 12 = $2,400 Coins accumulated: $2,400 ÷ $40,000 = 0.06 Current value: 0.06 × $52,000 = $3,120 Profit/loss: $3,120 − $2,400 = +$720 Profit/loss %: $720 ÷ $2,400 = +30% The DCA schedule turned $2,400 of contributions into a position worth $3,120 today — a 30% gain on the amount actually invested.
This calculator works from an average entry price you supply — it doesn't calculate that average from a real per-period price history, so the result is only as accurate as the average you enter. It also ignores trading fees, which reduce both the coins you accumulate and your final return; use the exchange fee calculator alongside this one for a fuller picture.
Perguntas frequentes
What is dollar-cost averaging?
It's investing a fixed amount on a regular schedule instead of all at once, so you buy at a range of prices over time. This averages out your entry price and reduces the risk of committing everything right before a downturn.
How do I find my average entry price?
Add up the total amount you've invested and divide it by the total number of coins you hold. Most exchanges show this figure directly on your position or portfolio page.
Does this calculator account for fees?
No — it works from the amount invested and the entry and current prices only. Trading fees reduce the coins you actually accumulate, so your real return will typically be a little lower than this calculator shows.
Is DCA better than investing a lump sum?
It depends on price direction: a lump sum outperforms DCA in a rising market, while DCA reduces regret and risk in a falling or volatile one. DCA is best understood as a risk-management approach, not a way to guarantee a higher return.
