Capital Budgeting & NPV

June 13, 2026

7 min read

We covered net present value from the ground up — the formula, the decision rule, a worked example, and then the Netflix streaming case to show how NPV works in a real strategic decision.

WHAT IS NPV AND WHY DOES IT MATTER?

NPV asks a single question: if you add up every dollar a project will ever generate, converted to today's dollars, and subtract what you spend today, is anything left over? A positive answer means the project creates value; a negative answer means it destroys value.

“this is fundamental. If you take one thing away from this entire unit it's NPV”centrality of NPV

The NPV Decision Rule

NPV greater than 0: accept the project — it creates value above your required return

NPV less than 0: reject the project — it destroys value

NPV equals 0: indifferent; you would accept, but no extra value is created

“NPV greater than zero, accept. That phrasing exactly. I will ask it exactly that way.”

Worked Example

1. Initial investment = $100,000

2. Year 1: $60,000 / 1.10 = $54,545

3. Year 2: $60,000 / 1.21 = $49,587

4. Sum = $54,545 + $49,587 = $104,132

5. NPV = $104,132 - $100,000 = +$4,132 — positive, so accept

Session Plan

45 min total

Timed Multiple Choice Drill

12 min

Practice quiz on the MAIN causes — the dreadnought, alliance memberships, and the Balkans 'powder keg.'

Alliance System Identification Test

8 min

Triple Alliance vs. Triple Entente from memory — the mix-up your instructor warns about every year.

Timeline Sequencing Challenge

10 min

Write the July Crisis timeline from memory, then check it against Section 4 of the handout.

Short Answer Practice Test

10 min

Two practice answers: nationalism in the Balkans, and why Britain really entered the war.

Thesis Argument Review

5 min

Recall the core thesis — 'the spark vs. the gasoline' — with one example for each cause.

Your instructor states the exam format outright and keeps emphasizing the same high-confidence questions. Practice testing mirrors that structure exactly — so you drill the distinctions that will actually be graded.
