Share assumptions, never dollar amounts
Links include eligible rate, term or frequency assumptions only. Dollar amounts are never included. Recipients must enter their own amounts; the link will not reproduce your full financial scenario.
HOW IT WORKS
Calculation method
Apply a contribution toward underweighted holdings or allocate a withdrawal in proportion to current holdings. Calculate post-flow target amounts from the entered percentages. In the trade-to-target option, compare those amounts with post-flow holdings; in the cash-flow-only option, do not sell holdings and report any remaining purchase gap.
KEEP IN MIND
Assumptions & limits
Target allocation percentages must total 100%; the calculator does not recommend a target mix.
Dollar calculations assume no price movement while cash flows or trades execute.
Taxes, trading costs, spreads, fractional-share and account rules are excluded.
