I know the current stance of the markerplace fees for dev products is 30% of price. How would they calculate say 30% of 5. I know its 1.5 but do they round to 2 or 1?

Marketplace fee uses the form of rounding they usually teach you at schools.

Itâ€™s accurate to the tenth. If the decimal is 0.4 or below, then itâ€™s rounded to 0. If itâ€™s 0.5 or above, then itâ€™s rounded to 1.

In your example, it would round to 2 since 0.5 is 0.5 or above.

So that means if my gamepass is 5 robux, i earn 3?

Youâ€™d earn 3 robux. 30% of 5 is 1.5, so we round up to 2. Like stated in the reply above. 5-2=3, so youâ€™d earn 3 robux.

If the number was 1.8 youâ€™d get 2.

If the number was 1.4, youâ€™d get 1.

If itâ€™s 0.4 or less, then donâ€™t add anything. It stays at whatever number it was before.

If itâ€™s 0.5 or more, then add 1. It goes up by 1.

But donâ€™t I earn 70% of the profits? So based off of the rounding 70% of 5 is 3.5 and since the marketplace fee rounds up I get 3 robux?

Mb, I misread the question. Youâ€™re earning 3.

Roblox specifies that they take off tax, so I think they would calculate the 30% and then subtract it from your 5.
