A financial appraisal of a fictional community investment with counterfactual, incremental costs, discounted values, distribution and sensitivity.

Keep your working files in your own notebook or software. Save a private description, checklist, and work link in My Proof.

What to include

  • A baseline/project comparison with incremental service and scope.
  • An incremental resource-cost and transfer-incidence table.
  • A dated present-value worksheet with real/nominal consistency.
  • A deduplicated benefit inventory with valuation limits.
  • A base/low net-value table and distribution note.
  • A completed fictional public-spending financial appraisal.

Review and revise

Use these criteria to check your work and choose what to improve.

  • All supplied records reconcile and the decision uses the named case rules.
  • Calculations show units, intermediate values and a second check.
  • Changed-input practice revises the affected result and identifies uncertainty.
  • The final project combines six lesson records, separates fictional assumptions from current rules, and states a supported next step.

The idea in everyday life

This is an original fictional practice case. No account, payment, personal record or outside participation is required. Fictional community room currently serves 100 weekly visits. Proposed extension would serve 140. No other baseline change is assumed.

The idea

An appraisal measures change relative to what would happen otherwise; all current activity is not automatically a new project benefit.

Follow along

Define the no-project baseline — worked practice

An appraisal measures change relative to what would happen otherwise; all current activity is not automatically a new project benefit.

Use paper or a local table; label all amounts as fictional USD unless the case names another unit. Fictional community room currently serves 100 weekly visits. Proposed extension would serve 140. No other baseline change is assumed.

Copy as plain text
  1. 1. Step 1: State current/no-project service and timeframe

    State current/no-project service and timeframe.

    You should see: 100 visits/week without the extension.

    An appraisal measures change relative to what would happen otherwise; all current activity is not automatically a new project benefit.

  2. 2. Step 2: State project scenario on the same basis

    State project scenario on the same basis.

    You should see: 140 visits/week with it.

    Keep this intermediate result so the final decision can be checked.

  3. 3. Step 3: Calculate incremental visits

    Calculate incremental visits.

    You should see: 140−100=40/week.

    Keep this intermediate result so the final decision can be checked.

  4. 4. Step 4: Write the counterfactual boundary

    Write the counterfactual boundary.

    You should see: Only 40 visits are additional under this baseline; growth that would happen without the project would change this number.

    Keep this intermediate result so the final decision can be checked.

Now change one thing

No-project visits would grow to 110. Incremental visits against 140?

Your work

What to finish

A baseline/project comparison with incremental service and scope.

Common mistake

Watch for this

Claiming every project-scenario user is a newly caused benefit.

How can I tell I understand it?

Calculate incremental service against a stated no-project counterfactual on the supplied changed case while preserving the stated rule and checking the final record.
