Nothing makes me more annoyed than when simulations like this make assumptions which don't make any sense. For example.

>"Note: currently, ProjectiFi taxes inheritance as ordinary income for simplicity and to maintain a conservative estimation strategy. More nuanced options that more closely mirror current inheritance tax liability scenarios are coming soon."

This is an absolutely ridiculous assumption. Federal inheritance/estate taxes in the US don't start until $11 million. If you can't figure that out your app is not ready to publish.
