Calculator guide
Shipping Cost Calculator helps you explore the stated finance question. Start with the labelled inputs, then review the method, worked example and limitations before using a result.
Formula or method
Round each package dimension to the nearest inch. DIM weight = length×width×height/139. Assumed billed pounds = ceiling(max(actual pounds, DIM pounds)). Estimated cost = billed pounds × entered rate + fixed fees.
How to use this calculator
- Set Actual Weight (lb). The interface starts with 10; replace it with the value for your scenario.
- Set Package Length (in). The interface starts with 16; replace it with the value for your scenario.
- Set Package Width (in). The interface starts with 12; replace it with the value for your scenario.
- Set Package Height (in). The interface starts with 8; replace it with the value for your scenario.
- Set Assumed Rate Per Billable Pound ($). The interface starts with 1.25; replace it with the value for your scenario.
- Set Handling & Insurance ($). The interface starts with 6; replace it with the value for your scenario.
- Compare the result with the worked example, then vary one assumption at a time so you can see what changes.
Worked example
A 16×12×8 inch package at 10 lb has DIM weight 1536/139 = 11.05 lb, billed weight 12 lb, and cost $21 at $1.25 per billed pound plus $6 fees.
Understanding the result
Compare the output with the shipping cost calculator worked example using exactly the same inputs. A different assumption or rounding convention can produce a different displayed result; the output does not establish personal or professional suitability.
Limitations and assumptions
- Illustrative 139-divisor/whole-pound model, not a carrier quote. Carrier/service rounding, divisors, zones, minimums, and surcharges differ.
- The worked example demonstrates the stated assumptions, not a recommendation about your personal circumstances.
