Why current ratio matters to a first-time founder
The current ratio is a quick check of whether current assets cover current liabilities. Lenders and founders use it to spot near-term financial pressure, but the quality and timing of the assets matter. A high ratio built from unsold stock or overdue invoices can still hide a cash shortage, while different business models support different healthy ranges.
Examples of current ratio
A company has ¥12 million of current assets and ¥8 million of current liabilities. Its current ratio is ¥12 million divided by ¥8 million, or 1.5. That means it reports ¥150 of current assets for each ¥100 due in the short term. If ¥5 million of those assets is obsolete stock, the headline ratio overstates its practical protection.
Common misunderstanding
A ratio above 1 does not prove the company can pay every bill on time, and a ratio below 1 does not automatically mean insolvency. The formula is current assets divided by current liabilities at one date. It ignores exact due dates, cash generation, financing access, and asset quality. Working capital uses the same inputs but subtracts liabilities instead.
When to use it
Calculate the current ratio when reviewing monthly accounts, applying for finance, or comparing liquidity across periods. Investigate the movements behind it rather than chasing a universal target. Compare companies only when their industries and accounting policies are similar. For day-to-day survival, pair it with a cash forecast and schedules of receivables, inventory, and payments due.
