Bitcoin DCA calculator

Dollar-cost averaging isn't "just keep buying." Lay the plan out first: how much this whole schedule commits, how many buys it takes, what it works out to per month. Then pick a worst-case crash and see how deep your paper loss could get.

How much per buy (spare money only, USD)

How often do you buy?

How long is the plan? (months)

This DCA plan commits a total of — — buys in all —

How it's worked out: total invested = per-buy amount × number of buys; the number of buys converts your plan length at the frequency you picked (weekly ≈ 4.33/month, every two weeks ≈ 2.17/month, monthly = 1). This just lays your plan out into a few numbers; it fetches no live prices and predicts no coin price or return.

Assume the price falls how far at worst during the plan? (bear markets often start by cutting the price in half)

In the worst case, your maximum paper loss is about — i.e. the money you put in shrinks by —

This is a pure math demo: maximum paper loss = total invested × the crash you assume. It predicts no real price or return; it only shows how big a chunk of your DCA plan would sit as a paper loss in the worst case. People who can look at this number calmly are the ones who survive a real drop.

How to read these numbers

The thing DCA beginners most often miss isn't how much each single buy is — it's how much the whole schedule adds up to. Two hundred a month doesn't feel like much, but run it two full years and it's $4,800. Put the total in front of you first, and you know how big a share this plan takes of your whole net worth — that matters far more than which day you buy.

The second block doesn't ask "will I lose," it asks "how deep could the loss get." Crypto drawdowns run far deeper than most newcomers picture: after topping out near $69,000 in November 2021, bitcoin fell to roughly $15,500 by November 2022 — a drop of about 77% (public price data). Put the worst case into the math and you'll know how ugly the paper loss looks in that kind of market — accept it before you start, don't discover you can't stomach it after the drop.

DCA is not a free pass

Buying in batches smooths your cost and frees you from guessing the timing, but it doesn't guarantee a profit, and it won't shield you from a bear market. The real value of DCA is swapping a single all-in bet for steady, disciplined small buys — lowering the risk of buying at one high point and making it easier to stick with. For the trade-offs, read DCA or a single lump sum.

What this tool can't do for you

It won't tell you what to buy, and it won't predict the price — nobody can. All it does is turn your DCA plan and worst-case exposure into a few concrete numbers, so that before you place a real order you've thought through exactly how much you're committing and how much you'd have to ride out at worst. The rest of the judgment is still yours.

Once the plan is set, you'll want an account that can buy on a recurring schedule and set price alerts. I use Binance myself; register with code BN1918 for 20% off trading fees.

How to use this DCA calculator (open to read)

What is dollar-cost averaging (DCA)

Dollar-cost averaging, or DCA, means buying a fixed amount on a fixed schedule — weekly, every two weeks, or monthly — regardless of whether the price is high or low. Its point isn't to "buy the exact bottom"; it's to use discipline and time to spread your entry cost so you don't put everything in at a single high.

How this bitcoin DCA calculator works

Three steps: ① enter how much you plan to put in each time; ② pick the frequency (weekly / every two weeks / monthly); ③ pick how long the plan runs. The calculator instantly shows the plan's total invested, the cumulative number of buys, and the monthly equivalent. Frequency uses the common approximation: weekly ≈ 4.33 buys/month, every two weeks ≈ 2.17 buys/month.

Why look at worst-case exposure

The second block lets you pick an assumed crash and shows the maximum paper loss your plan would carry in that case. It's not a prediction — it's a stress test. If the number would keep you up at night, each buy is too large or the plan too aggressive, so dial it down first. People who can accept the worst case calmly are the ones who keep dollar-cost averaging through a real drop.

Who DCA suits

DCA fits long-term investors who don't have time to watch charts and don't want to guess the timing — especially people buying steadily with spare monthly cash. It lowers timing pressure but does not remove market risk; the price can still fall for a long time. Only ever DCA with money you could lose entirely without it changing your life.
