The financial cushion that lets a business survive unexpected events. Without reserve, every bad quarter becomes existential; with it, you have time to respond thoughtfully.

Definition

Cash Reserve - cash held separately as a safety buffer for emergencies, typically targeting 3-6 months of fixed operating expenses (higher for volatile, concentrated, or seasonal businesses).

Common uses

Risk management - the buffer against unexpected events
Strategic flexibility - reserves enable decisions that would otherwise be off the table
Lender comfort - banks evaluate creditworthiness against reserve levels

Watch out

Reserve in the same account as operating cash isn't really reserve - it gets used. Move it to a separate account and treat it as untouchable.

Frequently asked questions

What's a cash reserve?

Cash held separately as a safety buffer for genuine emergencies - a major customer leaving, economic downturn, unexpected lump-sum expense.

How much cash reserve should I have?

Conventional rule: 3-6 months of fixed operating expenses. Volatile or concentrated businesses should target 6-12 months.

Where should I keep cash reserve?

Liquid, safe accounts - business savings, money market, short-term treasuries. The goal is access on demand, not return.

Should reserve be in a separate account?

Yes. If mixed with operating cash, it gets used. The psychological wall of separation is what makes reserve actually function.

When should I use the reserve?

Genuine emergencies only - major customer loss, economic downturn, unexpected major expense. Not normal slow months or growth investment.

How do I build a reserve when I don't have one?

Set a monthly contribution (1-2% of revenue, automated), use windfalls (tax refunds, one-time gains), and don't touch it until you hit the target. Building a 3-month reserve takes 18-24 months for most businesses.
