How to use Portfolio Rebalance

Enter portfolio value, current allocation percents, and target percents per sleeve. Read buy/sell dollars needed to hit targets. Weights should sum near 100%.

Example: rebalancing a $20,000 portfolio

You hold BTC $12,000, ETH $5,000 and cash $3,000, with targets of 50%, 30% and 20%.

  1. BTC: target $10,000 − current $12,000 = sell $2,000
  2. ETH: target $6,000 − current $5,000 = buy $1,000
  3. Cash: target $4,000 − current $3,000 = buy $1,000

Sell $2,000 of BTC and use it to buy $1,000 of ETH and add $1,000 to cash. Include trading fees and taxes before you act.

Formula & methodology

target$ = portfolio × target%. delta$ = target$ − current$. Positive delta ⇒ buy; negative ⇒ sell. Drift = current% − target%.

Plan a multi-asset crypto rebalance

Portfolios drift when winners run. Rebalancing restores target risk without guessing notionals by hand. This tool turns percents into dollar trades you can take to an exchange.

Keep tax lots and transfer fees in mind — selling winners can create taxable events. Some investors rebalance with new cash (buy underweights only) to reduce sells.

Combine with the portfolio tracker for live marks and with the converter when sleeves are quoted in different fiats.

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.
