How do you calculate the new average price after buying more crypto?

New average = total dollars invested (old position value plus the new buy) divided by total coins held (old quantity plus new quantity). Buying more at a lower price than your current average always pulls the blended average down.

Is averaging down a good strategy?

It can lower your break-even price, but only makes sense if your reason for holding the asset hasn't changed. Adding to a losing position purely to lower the average, without reassessing the thesis, is a common way small losses become large ones.

What's the difference between average down and DCA?

Dollar-cost averaging is a scheduled, pre-committed plan to buy fixed amounts regardless of price. Averaging down is typically a reactive, one-off decision to add to an existing position after a price drop. The math for the resulting average cost is the same in both cases — see the DCA calculator for the scheduled version.

How much does buying more lower my average cost?

It depends on how large the new buy is relative to your existing position, and how far the new price is below your current average. A buy roughly equal in size to your existing position, at a meaningfully lower price, moves the average substantially; a small top-up barely moves it.

Move needed to break even

"Move needed to break even" is measured from the new buy price to the new average — it's how far price must rise from here for the whole position to be flat, not from your original entry.

How averaging down works

Averaging down means buying more of an asset you already own after its price has fallen, which pulls your blended cost basis toward the new, lower price. The math is simple: your new average is total dollars invested (old cost basis plus the new buy) divided by total coins held (old quantity plus the new quantity). Buy 1 BTC at $60,000, then buy $40,000 more at $40,000, and your average drops from $60,000 to $50,000 — a lower bar to clear for the position to turn profitable.

The size of the drop depends on how much new capital you commit relative to what you already hold. A small top-up barely moves the average; doubling your position at a much lower price can move it a lot, as the example above shows.

Averaging down vs. catching a falling knife

Averaging down is a deliberate risk decision, not a rescue button. It only makes sense if your thesis on the asset is unchanged and you have a reason to believe the lower price is a buying opportunity rather than the start of a larger decline. Committing more capital to a losing position without re-examining why it's losing is how small drawdowns become account-threatening ones — the same discipline that governs initial position sizing (see the position-size calculator) should govern every add.

Reading the break-even figure

This calculator reports two different numbers on purpose. "Average lowered by" tells you how much better your entry got. "Move needed to break even" is measured from today's price (your new buy price) to the new average — the more useful number, because it's the actual distance left to travel from here, not from your original, now-irrelevant entry. A smaller break-even gap means less price recovery is required before the position is flat.
