Dollar-cost averaging back-test

This does not project a return. It replays a real price history and reports what that schedule would have produced over that specific window — which is a fact about the past, not a forecast.

What this calculator ignores

  • A different window gives a very different answer. Try several before drawing any conclusion.
  • The window available here is short by investing standards. It cannot tell you what a decade would do.
  • Ignores fees, which on small recurring buys are proportionally large.
  • This is arithmetic on the numbers you typed. It is not advice, and it does not know your circumstances.
