Implemented rule
How the entered-cost comparison is calculated
This page documents the local calculator rule. It is not a carrier quote, rate table, or statement of carrier policy.
Formula
For each plan: total = postage + packaging/material + labor + other entered cost. Labor = handling minutes ÷ 60 × hourly labor rate.
Rounding point
Money is represented in integer cents. The labor amount is rounded half-up to the nearest cent once per plan; the direct entered costs are already parsed as cents.
Synthetic example
The illustrative inputs produce Plan A = USD 10.40 and Plan B = USD 10.70. These numbers are synthetic test values, not observed prices or carrier quotes.
Input caps versus carrier policies
Money fields accept up to USD 100,000 and handling time accepts up to 1,440 minutes. These are calculator input caps only; they do not describe any carrier's limits, eligibility, or pricing policy.
Omissions
Taxes, duties, platform fees, insurance, refunds, service speed, coverage, delivery risk, suitability, and any cost not entered are outside the result.
Source of the result
The source is the implemented local calculation rule applied to the values in the form. No carrier lookup, external rate request, or recommendation is performed.
