About Rebalancing Amount Calculator

Rebalancing restores the intended mix after market moves have shifted it. Because it sells what has risen and buys what has lagged, it enforces a disciplined contrarian trade and keeps portfolio risk at the level you chose.

Formula

Rebalance

Shift = (equity + debt) × target - current equity

Frequently Asked Questions

How often should a portfolio be rebalanced?

Annually, or when an asset drifts beyond a set band. More frequent rebalancing adds costs without much benefit.

Does rebalancing raise returns?

Not reliably. Its main job is controlling risk, though it can add a small return bonus when assets are volatile and mean-reverting.
