· 01 · Pick an asset

Three categories. One calculator.

All assets
· 02 · The Method

Pick an amount. Pick a frequency. Don't stop.

That's the whole strategy. Dollar-cost averaging spreads your buy-in across time so you stop trying to time the market — and start owning it.

  1. 01

    Choose an amount you can ignore

    Whatever fits your budget. Once set, treat it like rent — it leaves your account whether you feel like investing or not.

  2. 02

    Pick a fixed cadence

    Weekly is the sweet spot. Bi-weekly works on payday schedules. Monthly is the bare minimum.

  3. 03

    Run it for a decade, not a year

    DCA is a 5–30 year strategy. Anything shorter is just trading with extra steps.
