Lump Sum vs Dollar-Cost Averaging

All at once, or a little at a time? Put the same total dollars into Bitcoin both ways, against real price history, and see which strategy actually came out ahead — and by how much.

Real data · same total invested
The scenario01

How it works · methodology

The math, in the open.

DCA value  = Σ(contribution ÷ price_month) × price_latest
Lump value = (total invested ÷ price_first) × price_latest
Winner     = whichever final value is higher
Both invest the same total. DCA buys monthly at each month's close; lump sum buys everything at the first month's close. We compare end values.
contribution
Fixed monthly amount (DCA)
price_first
First month's closing price (lump-sum buy)
price_latest
Most recent closing price
total invested
Sum of all DCA contributions = lump-sum amount

Assumptions & limits

  • Both strategies invest the identical total amount; only the timing differs.
  • Monthly closing prices; intra-month timing and exact buy dates are ignored.
  • No fees, spreads, or taxes.
  • Historical, single-asset (Bitcoin) result — not a general rule and not investment advice.

Questions about the debate

Which is better, lump sum or dollar-cost averaging?
On average and historically, investing a lump sum up front beats dollar-cost averaging — studies of U.S. markets put lump sum ahead roughly two-thirds of the time, because markets trend upward and lump sum keeps money invested longer. DCA wins when the market falls after you start, and it reduces timing risk and regret. This tool shows both outcomes with real prices for the period you pick.
How is the comparison fair?
Both strategies invest the same total amount of money. The lump sum buys everything at the first month’s price; DCA spreads the same total across equal monthly buys. We then compare the value of each at the end of the period.
Why does Bitcoin favor lump sum so strongly?
Bitcoin has risen enormously over its history from a very low base, so buying everything early (lump sum) usually beats spreading purchases out. Over shorter windows that begin near a peak, DCA can win. Change the start year to see how much it matters.
Does this include fees or taxes?
No. Results exclude trading fees, spreads, and taxes, and use monthly closing prices. They are estimates for education, not investment advice.
