Value projection
Annual allowance usage
The taxable scenario subtracts the specified tax rate from gains to show the after-tax value.
FAQ
Can I adjust the allowance values?
Yes. Edit the annual and lifetime allowance fields to match future revisions or alternative limits for your simulation.
How are fees and taxes applied?
The trust fee is deducted from the annual return before compounding. Taxable accounts apply the selected tax rate (20.315% by default) to gains at the end of the period.
