Load Profit Calculator

A profitability decision tool that tells truckers whether a load is worth taking before they accept it.

What it solves

Truckers often accept loads based on gross pay without knowing the real profit. A load can look good upfront but turn unprofitable once fuel, deadhead miles, driver pay, equipment payments, insurance, maintenance, tolls, dispatch fees, and factoring fees are subtracted. There was no fast way to reduce all of those costs into one clear profitability answer.

Built for Owner-operators, small trucking companies, fleet owners, dispatchers, and logistics managers.

Overview

The Load Profit Calculator estimates the true profitability of a freight load before a trucker accepts it. A user enters load pay, loaded and deadhead miles, fuel price, and MPG and instantly sees net profit, cost per mile, revenue per mile, profit margin, break-even rate, recommended rate, and an Accept/Review/Reject decision. Advanced cost inputs, custom cost and revenue items, equipment profiles, and company cost settings let operators model real cost structures, while a warning and insight engine explains the result in plain language. Saved calculations preserve a snapshot of their assumptions, and a dashboard summarizes profitability across loads.

What this demonstrates

Shows an isolated, deterministic calculation engine with profit, decision, and warning logic separated from the UI. It proves snapshotting so saved results never change when settings change, workspace-scoped multi-tenant data with role-based access, and a clean progressive-disclosure interface over a deep cost model.

What makes it different

This is not a basic calculator — it is a professional decision tool that tells you whether a load is actually worth taking.

  • Deadhead miles are always countedEmpty miles are never ignored in the cost math.
  • Never show profit without its assumptionsEvery result exposes the numbers behind it.
  • Saved calculations preserve a snapshotOld results never change when settings change.
  • Calculation logic stays separate from the UIThe engine is reusable and testable.
  • Simple on the surface, deeply customizable underneathAdvanced costs hide behind progressive disclosure.
  • Workspace data is never shared across companies

How it works

  1. Enter load pay, loaded and deadhead miles, fuel price, and MPG
  2. Optionally select an equipment profile and open advanced costs
  3. See net profit, per-mile metrics, break-even and recommended rate instantly
  4. Read the Accept/Review/Reject decision and plain-language warnings
  5. Save the calculation with its assumptions snapshot
  6. Review profitability across loads on the dashboard

How the decision works

Load Decision

  • Net profit

    Rejects the load when profit falls below zero.

  • Profit margin vs target

    Flags Review when positive but under target, Accept when at or above.

  • Deadhead share

    Warns when deadhead exceeds 25% of total miles.

  • Fuel share of revenue

    Warns when fuel exceeds 35% of gross revenue.

  • Break-even rate

    The minimum per-loaded-mile rate needed to cover cost.

How it is built

A Next.js and React frontend calls a modular TypeScript calculation library, backed by a Prisma data layer on SQLite. Custom JWT-based auth scopes every record to a workspace, and results render in dashboards and charts.
