How rebalancing trades are estimated

The calculator compares current asset values with target weights after any new cash is added. Assets above target show sell amounts, and assets below target show buy amounts.

Using a minimum trade size

Small trades can create unnecessary fees or tax lots. Set a minimum trade size to ignore tiny adjustments and focus on the allocation drift that matters most.
