Rebalancing is not free
Transaction costs, tax lots, account type and risk tolerance matter. This calculator shows allocation math only, not an investment recommendation.
Example
With a 100,000 portfolio at 70% stocks, stock value is 70,000. A 60% target means 60,000 in stocks, so the simplified rebalance is to sell 10,000 of stock exposure.
Common mistakes
Check whether new contributions, dividends or tax-advantaged accounts can rebalance the portfolio with fewer taxable trades.
Limitations
This is not investment advice. It does not model taxes, bid-ask spreads, fund restrictions, risk tolerance or multi-asset portfolios.
