Portfolio Allocation Calculator
Set a target weight for each coin and see the buys and sells that bring your holdings back in line, or split a new budget by the same weights.
Rebalance preview
Trades needed to reach your targets at current prices. Fees are not included.
Diversification and allocation
The arithmetic behind the table above.
Current weight
weight = asset value ÷ portfolio valueEach asset’s share of the total value you entered.
Target value
target = portfolio value × target %What each position would be worth at your chosen weight.
Buy or sell
trade = target − currentThe difference between target and current value. The tool never suggests weights — it only works out the trades for yours.
About this page
Crypto portfolio allocation means deciding what share of your money goes into each coin, then trading to keep those shares. This calculator has two modes. Rebalance holdings takes what you hold now and your target weights, and returns the buys and sells that close the gap, in dollars and in coins. Split a budget divides one amount across the coins you pick.
The arithmetic is simple. Current weight is an asset's value divided by the portfolio value, target value is the portfolio value times the target share, and the trade is target minus current. A donut compares current and target weights, and turnover shows what share of the portfolio would change hands. Targets must add up to 100%, and a button rescales them if they do not.
Assets come from a live list of the largest coins, stablecoins included, with up to 20 in one portfolio. Prices come from Binance, OKX and Coinbase, with DefiLlama for coins they do not list, and refresh every 5 minutes. The tool never suggests weights and leaves trading fees out; the allocation itself is your decision.
