Every finance question is one of four questions

Corporate finance looks like a long list of techniques and is really four questions asked repeatedly. What is a future rupee worth today? Which of the things we could spend money on is worth doing? Where should the money come from, and what does that source cost? And of what we earn, how much should we keep and how much should we return?

The first question is time value of money, and it underlies everything else on this page. Net present value, internal rate of return, discounted cash flow valuation and the pricing of a bond are all the same discounting arithmetic wearing different labels. Get comfortable with it and half of what follows stops being new material.

The second question is capital budgeting. The third splits into cost of capital, which prices each source, and capital structure, which mixes them. The fourth is dividend policy. Working capital sits underneath all four, because a business that cannot fund its own operating cycle never gets to make the interesting decisions.

The Concept Map

The ten concepts, and what each one decides

Arranged so that each concept only needs what the ones above it have already established.

Time Value of Money

A rupee today is worth more than a rupee next year, and discounting makes the two comparable. Every valuation technique on this page is an application of it.

Financial Ratios

Turning absolute figures into comparable ones. A profit of two crore means nothing until you know it came from twenty crore of revenue or two hundred.

Capital Budgeting

Choosing between projects using net present value, internal rate of return and payback. The three can disagree, and knowing which to trust is the actual skill.

Working Capital Management

Funding the gap between paying suppliers and being paid by customers. It consumes cash in exact proportion to growth, which is why fast growth strains cash.

Cost of Capital and WACC

What money costs, weighted across debt and equity. It is the hurdle rate a project has to clear and the discount rate a valuation has to use.

Leverage and Gearing Ratios

How much of the balance sheet is borrowed, and how sharply profit moves when revenue moves. Leverage amplifies both directions equally.

Capital Structure

The debt and equity mix. Debt is cheaper and must be repaid; equity is expensive and permanent. The trade-off is between cost and survival.

Dividend Policy

Whether to return cash or reinvest it. The right answer depends entirely on whether the business can earn more on the money than the shareholder could.

Mergers and Acquisitions

Buying growth instead of building it. The valuation is the easy part; the synergies assumed to justify the price are where most of the value is lost.

Derivatives Basics

Contracts whose value derives from something else. Used to hedge a known exposure or to take a position, and the two uses have very different risk profiles.

Test yourself on Finance

Ten topics covering ratios, discounting, capital budgeting and structure. Finance rewards fluency with a small number of formulas far more than breadth.

Common Questions

Before you start

Is corporate finance different from personal finance?+
The arithmetic is identical and the objective is not. A business discounts cash flows to decide whether a project earns more than its cost of capital. A household discounts to decide whether an expense today is worth a smaller balance later. Time value of money, compounding and the trade-off between risk and return apply to both without modification. What differs is that a business can raise equity and a household generally cannot.
NPV or IRR — which should I trust when they disagree?+
Net present value, in almost every case. IRR reports a percentage, which feels comparable across projects but quietly assumes intermediate cash flows are reinvested at that same rate, which is rarely true. IRR can also produce several answers when cash flows change sign more than once. NPV reports the value created in rupees at a discount rate you choose explicitly, which is both harder to misread and harder to game.
What discount rate should I use?+
For a business appraising its own project, the weighted average cost of capital, adjusted upwards if the project is riskier than the firm as a whole. For an investor valuing a company, a required return that reflects the risk being taken rather than the return being hoped for. The number matters enormously: a two point change in the discount rate can move a long-dated valuation by a third, which is why every serious valuation is presented as a range.
