How Your New Average Is Calculated
Your average entry is just total money spent divided by total coins owned. Add the cost of your existing position (coins held times your old average) to the cost of the new buy (new coins times their price), then divide by the combined coin count. Buying below your average pulls it down; buying above pushes it up.
Cost-Basis Concepts at a Glance
| Concept | What it means |
|---|---|
| Averaging down | Buying more at a lower price pulls your average entry down. |
| Averaging up | Buying more at a higher price raises your average entry. |
| Break-even | The price you need to sell at to recover everything you've spent. |
Frequently Asked Questions
Averaging down means buying more of a coin you already hold at a lower price than you first paid. Because your new average is the total spent divided by total coins, those cheaper coins pull your average entry below where it was, lowering the price you need to break even.
No — it usually increases it. A lower average makes recovery look closer, but you're committing more capital to a position that's already moving against you. If the price keeps falling, you lose on a larger stack. Size every add against a plan, not just to chase a better average.
Yes. Your average entry is the price at which your total proceeds equal your total cost, so selling the whole position at that price returns exactly what you put in. Anything above it is profit; anything below is a loss — before fees are taken into account.
No. This calculator works from coin amounts and prices only, so your real break-even sits slightly higher once exchange fees on both the buys and the eventual sell are added. Treat the result as your pre-fee floor and add a small buffer for the round-trip cost.
