Answer

What is WACC, and how do you calculate it?

The blended required return of all capital providers, used as the DCF discount rate. WACC = E/V × cost of equity + D/V × cost of debt × (1 − tax rate). Cost of equity usually comes from CAPM: risk-free rate + β × equity risk premium.

Why trust the answers

Written by people who've been on both sides of the table.

The technicals that actually matter when real capital and real diligence are on the line.

In-house

Top tech finance

How the concepts play out in practice — not just how they sound in a textbook.

Spaced repetition that sticks

An SM-2 scheduler tracks every card per-user, so you spend your time on what you're about to forget.

Always current

New questions ship as data, not app updates. The bank keeps growing while you study.

Division add-on decks

Restructuring, Leveraged Finance & Capital Markets add-ons are coming soon — bank-specific decks to follow.

Straight from the bank

The questions that actually get asked.

A few real cards. Reveal each answer the way you would in the app.

ValuationHardA DCF gives a value that seems too high. Which assumptions do you check first?+

The terminal value (often 60–80% of total value): the perpetuity growth rate and the exit multiple. Then WACC — too low inflates value — and the revenue/margin assumptions in the projection.

M&AMediumWhat makes an acquisition accretive or dilutive to EPS?+

If the after-tax yield on what you're acquiring exceeds the after-tax cost of financing it (cash, debt, or stock), EPS rises. Rough all-stock rule: higher acquirer P/E than target → accretive.

EV vs EquityHardWhy do you subtract cash when going from equity value to enterprise value?+

EV is the cost to acquire the operating business. Cash is a non-operating asset the buyer effectively gets back, so it nets against the debt assumed and reduces the net price.
