Cost Analysis Model

A simple guide to how the Cost Analysis Model evaluates multi-year savings projections.

What this model does

This model calculates the year-by-year financial reality of the proposed transport cuts. It builds a multi-year budget timeline and factors in grandfathering rules (older siblings keeping eligibility), alternative small-vehicle contracts, and the administrative costs of parental appeals.

The key question it answers: Do the transition rules, extra taxis, and parent appeal costs wipe out the savings, meaning the Council's plan won't actually save money?

Baseline Savings Projections

Standard financial models often project immediate savings by assuming that entire bus routes can be cancelled or scaled back on day one. This model evaluates how phasing policies and transitional arrangements affect those initial assumptions.

Cost Factor 1: Grandfathering (Phased Implementation)

Under typical transition arrangements, students who are already enrolled retain their transport eligibility.

As a result, existing bus routes must continue operating to service remaining eligible students, meaning the cost of the larger bus contracts may not decrease immediately.

Cost Factor 2: Alternative Vehicle Contracts

If a high-capacity bus route is discontinued or restructured, any remaining eligible students along that route must be transported using alternative vehicles (such as minibuses or taxis).

These smaller vehicles carry a higher per-pupil cost, which can offset the savings from cancelling the larger bus contract.

Cost Factor 3: Appeals Administration Overhead

Changes to transport eligibility criteria typically result in a higher volume of parent appeals.

Processing these appeals through multiple statutory stages (Internal Review, Independent Appeals Panel, and Local Government Ombudsman) incurs significant administrative overhead, including staff time and legal review costs.

How to test the model yourself

The Cost Analysis Model allows you to adjust these variable cost factors over a multi-year timeline to analyze their cumulative impact on the projected savings.

  • Adjust sliders for grandfathered pupil numbers and taxi daily rates.
  • Adjust the percentage of parents expected to appeal and the unit cost per appeal stage.
  • Observe the cumulative net financial balance across the timeline as different variables are introduced.
