Here is the breakdown of what my first booking under this new fee came out to
Net Take Home: $998.79
Expected Amount: $1,016.64
Difference: $(17.85)
So somehow I am still off 1.66%, which is pretty close considering I didn't get the 3% back they were previously taking. Not sure where I need to adjust the math to make it right though. This doesn't even cover the taxes that airbnb is still collecting.
Looks like you did not apply 18.34% to rent AND fees. In your case cleaning. If you did than 18.34% of $1016.64 would be $186.45.
