Cash Balance
The amount of liquid cash a company holds at a point in time, after opening balance, collections, funding inflows, and operating outflows are netted together.

What it measures
The liquid cash a company holds at a moment in time: opening cash plus cumulative inflows (customer collections and capital injections) minus cumulative outflows (operating burn and capital deployment). This is the bank-account position on the balance sheet, not the accrual-basis income statement and not the cash-flow waterfall that explains how it moved.
Why it matters
Cash Balance is the survival metric. No matter how strong your revenue or growth, you run the business on cash — without it you cannot make payroll, pay cloud bills, or fund the R&D that sustains the revenue in the first place. When cash falls below a few months of burn, fundraising or a pivot stops being a choice and becomes a forced move. A strong cash position does the opposite: it lets you invest in hiring, product, and market expansion from a position of strength rather than desperation. Investors track cash and runway ruthlessly, because they determine how long you have to hit the milestones that justify the next round.
How to read it
Never read Cash Balance as a lone snapshot — always pair it with monthly net burn to compute runway (Cash Balance / monthly net burn = months of runway), then compare that runway to your plan. The real question is whether you have enough cash to reach your next milestone — profitability, the next round, or positive cash flow — before the balance hits zero. If runway drops below 12 months, flag it on the board dashboard and start fundraising conversations immediately; VCs move slowly, so plan on a 6-month lead time. Then read the components to diagnose direction: falling collections signal a customer or billing problem, spiking outflows signal unplanned spend or hiring, and delayed funding signals risk to the plan. Each points to a different fix.
What good looks like
Good
Cash balance stable or growing month-over-month, with runway comfortably above 12 months and inflows (collections plus funding) at or above burn.
Watch
Cash balance flat or slowly declining, runway between 6 and 12 months, net burn accelerating, or funding and collections becoming less certain.
Bad
Cash balance critically low with runway under 3 months, burn unsustainable without new funding or near-term profitability, and the funding pipeline empty or collections deteriorating.
Watch-outs
- Reading the balance without runway. A $5M cash balance means nothing on its own — at $200K/month net burn it is 25 months of runway and comfortable; at $1.5M/month it is barely three months and a crisis. Always divide by net burn before reacting.
- Confusing accrual profit with cash. A business can post positive net income and still run out of cash when revenue is recognized upfront but collected over time, or when receivables stall. Track the bank balance, not the P&L, for liquidity.
- Ignoring lumpy, non-operating outflows. Annual tax payments, debt repayments, capital equipment, and founder or investor distributions can drain cash in a single month even when operations look stable. Model these timing spikes, not just average burn.
- Counting billings as cash. Signing a contract or sending an invoice does not move the bank balance — only collection does. Treating bookings or receivables as cash overstates liquidity and shortens your runway by surprise.
Worked example
Hypothetical
Your SaaS opens January with $500K in cash. During January you collect $80K from customers, receive a $200K venture funding wire, and burn $120K on operating expenses, closing at $660K. In February you collect $85K, take no new funding, and burn $130K after a hire, closing at $615K. Runway is $615K / $130K = 4.7 months — tight. You need profitability or fresh funding by mid-year, which means starting those conversations now.
