What does a dimensional weight calculator change?+
It replaces the scale weight when the carton is light for its size. The charge then uses the dim weight. Dense freight keeps the scale weight.
Why is 139 already filled in?+
It is a common domestic divisor, not a rule that every carrier uses. Replace it with the divisor on the rate sheet you are estimating.
Does the surcharge stack on the base fee?+
Yes. The percent applies to the base plus the weight charge. If your carrier applies fuel only to the weight line, lower the base or the percent so the total matches their method.
Is this a live rate?+
No. Nothing on the page calls a carrier. It multiplies the numbers you enter. Zone, service level, and accessorials stay outside the formula until you put them in the base or the rate.
