How to rebalance a crypto portfolio by target weights

Open tool

Calculate buy/sell amounts to restore target allocation percentages after prices drift — before you trade.

Turn “I’m overweight BTC” into concrete trade sizes so rebalancing is systematic instead of vibes.

Purpose

Turn “I’m overweight BTC” into concrete trade sizes so rebalancing is systematic instead of vibes.

When to use it

  • Prices moved and weights drifted from targets
  • You add cash and want proportional buys
  • You trim winners on a schedule
  • You compare drift vs impermanent-loss style rebalancing in DeFi

How to use it

  1. Enter holdings and prices. List each asset with quantity and mark price (converter helps).
  2. Set target weights. Percents should sum to 100% for a full book.
  3. Read required trades. Note what to buy/sell to hit targets.
  4. Apply fees and tax awareness. Rebalances realize gains — model fees and local tax rules separately.

Benefits

  • Clear trade list from weights
  • Pairs with portfolio tracker
  • Supports disciplined drift control
  • Free browser math

Pitfalls to avoid

  • Trading fees and taxes on every rebalance
  • Illiquid alts may slip
  • Targets are policy, not alpha
  • Not automated execution

When to rebalance vs let winners run

Calendar or band rebalancing (e.g. when a sleeve drifts ±5%) reduces concentration risk but can cut compounding winners. Use the tool to price the trade list; use your policy to decide whether to act.

Worked example: $10k book targeting 60/40 BTC/ETH that drifted to 70/30 needs roughly selling $1k BTC and buying $1k ETH (before fees) to restore weights.

Common mistakes

Rebalancing too often on noisy days; ignoring stablecoin sleeves; forgetting that LP positions are not the same as spot weights (see impermanent loss).

Frequently asked questions

What does the rebalance calculator do?+

You enter current weights and target weights (plus portfolio value). It shows how much USD to buy or sell in each sleeve to hit the targets.

Do weights need to sum to 100%?+

Targets should sum to ~100%. If they do not, normalize or fix inputs before you trade — the tool highlights the drift.

Does this place orders?+

No. It is planning math only. Execute on your exchange or wallet, watching fees and tax lots.
