Do you know your marginal tax rate?

Sounds familiar.
Wikipedia sums up the log notation nicely. However, they don’t include tax authorities’ preferences.

Either way, the initial survey lacks “yes” as an option :smiley: . One reason I made a table for a range of income (and a bar chart for my spouse) back then was to calculate the impact of pillar 2 buy-ins. If you use this option, and as long there’s enough limit left, you can basically pick your desired marginal rate for a while.

I challenge the statement that in maths it is common to use log to mean natural log. Mathematicians are lazy as hell and for sure will write ln\ x instead of log\ x or log_e\ x whenever possible.
