Three assets
Current weights sum

| Asset | Current $ | Target $ | Trade |
|---|---|---|---|
| Bitcoin (BTC) | $4,500.00 | $4,000.00 | -$500.00 |
| Ethereum (ETH) | $3,500.00 | $4,000.00 | +$500.00 |
| Stablecoin | $2,000.00 | $2,000.00 | $0.00 |
Positive trade means you would add that much notional value to the asset (buy or overweight); negative means trim or sell that amount. Totals ignore fees, spreads, and taxes. This is educational only and not investment advice.
Tips
Both sides scaled
Current & target
Useful when you copy rough weights from a dashboard or spreadsheet.
Table output
Current $, target $, trade
Compares where you are versus where you want to be at one point in time.
Liquidity check
Total buys & sells
Helps you see how large the round trip is before fees.
Labels you control
Any names
Name assets to match how you track positions on an exchange or wallet.
Disclaimer
Volatility & tax
Crypto prices move quickly; use results as a planning aid only.
Not crypto-only
General weights
You can reuse the same approach for equities or funds if values are in one currency.
Default sample: $10,000 portfolio, current 45% / 35% / 20%, target 40% / 40% / 20%.
Bitcoin (BTC)
Trade
-$500.00
Ethereum (ETH)
Trade
+$500.00
Stablecoin
Trade
$0.00
The calculator converts your percentage weights into dollar amounts for each asset, then finds the difference between target and current dollars. That difference is the suggested trade for each line. When percentages on either side do not sum to 100%, each side is scaled so the three weights keep the same proportions but add to a full 100% allocation.
Current $ (i) = Portfolio value × (Current weight i ÷ 100)Target $ (i) = Portfolio value × (Target weight i ÷ 100)Trade (i) = Target $ (i) − Current $ (i)Weights are normalized independently on the current and target rows when their sums differ from 100%.

Markets move at different speeds. Without rebalancing, a portfolio can drift far from your intended risk level. Periodic or threshold-based rebalancing is one way to bring allocations back toward plan, though it can trigger costs and taxable events in some accounts.
The first asset is overweight versus target, so the trade column shows a negative amount (trim). The second asset is underweight, so the trade is positive (add). The third asset matches on both sides, so its trade is about zero before rounding.
Always confirm prices, minimum trade sizes, and tax implications on your exchange or with a professional.
