# How Finance Works **Mihir Desai**  --- _Finance isn't accounting with more ambition. It's a different lens entirely._ Two ideas underpin everything Desai teaches, and they're deceptively simple. Cash matters more than profits. The future matters more than the past. Most financial analysis ignores both, which is why most financial analysis misleads. Accounting profits are opinions dressed as facts. Management chooses depreciation schedules, decides when to recognise revenue, determines what counts as a one-time charge. Cash can't be manipulated the same way. It either arrived or it didn't. The divergence between the two is what [[Cash and profit]] maps out, and it's often the first thing that reveals whether a business is genuinely healthy or merely well-presented. When you learn to read the statement of cash flows before the income statement, you're asking a different question: not "what did the accountants decide happened?" but "what actually happened?" Revenue is vanity, result is sanity, cash is king, as Desai puts it. Most board packs lead with the income statement and bury the cash flow at the back, if it's there at all. The order tells you which lens the organisation trusts, and it's usually the wrong one. --- **The second shift is harder: thinking forward instead of backward.** Accounting characterises what has already happened. Finance asks what's coming next. The value of any business is a function of its future cash flows, not its historical performance. This sounds obvious until you watch a management team spend an entire strategy day debating last quarter's variances rather than next year's reinvestment decisions. Desai's clearest formulation: to create value, a company must beat its cost of capital, sustain that advantage for many years, and reinvest additional profits at rates that justify the capital consumed. Failing the first is fatal immediately. Failing the second means your competitive position is eroding. Failing the third is the discipline [[Paying for growth]] explores: the question of when reinvestment creates value and when it compounds into diminishing returns. The connection most people miss is that an investor's expected return becomes the cost of capital for the manager on the other side of that decision. Finance isn't a department. It's embedded in every pricing decision, every hiring plan, every inventory commitment. The manager who thinks finance happens when the company raises debt or equity has already lost the plot. Finance is happening every time capital is deployed, which is every day. --- **When you sit down with a set of accounts, [[Ratios]] are where these two lenses become practical.** Four questions organise the numbers: how is the company generating profits, how efficiently, how is it financed, and can it generate cash quickly? The first step when facing a sea of figures isn't to calculate more of them. It's to find the extreme ones and build a story around them. Ratios without a story are just arithmetic. What changes when you adopt Desai's lens is more than technique. You stop reading financial statements as scorecards and start reading them as diagnostic tools. You ask "where is the cash?" before "what were the earnings?" You treat the income statement with appropriate scepticism and the cash flow statement as ground truth. And you stop treating finance as something that happens in the treasury function and start seeing it in every decision that allocates capital. That's [[Beyond margins]] in practice: understanding the full picture of how a business generates and uses its resources, not just whether the margin line looks respectable. ---
