The 60/40 axle placement formula is a great starting point and does take into account the tongue of the trailer from where the trailer sits on the hitch ball. Please keep in mind that this is a very basic formula or estimate for axle placement.

For a much more accurate way to determine the correct axle placement for your trailer, take a look at the formula that I have included for you. This formula also takes the length of the trailer tongue into consideration.
