Current Ratio Calculator
From current assets and current liabilities, compute the current ratio — a measure of short-term solvency.

計算結果
重點速覽：Current ratio = current assets / current liabilities (x). It measures short-term solvency: >1 means assets cover near-term debt; higher = more buffer, but too high may mean idle cash or piled inventory. Read with quick ratio and cash ratio. WARNING: Static snapshot; high ratio doesn't guarantee realizable assets (slow stock, bad debts) — check composition, compare with peers/history. Education, not advice.
計算公式
流動比率 = 流動資產 ÷ 流動負債。
$$\text{Current Ratio} = \dfrac{\text{Current Assets}}{\text{Current Liabilities}}$$使用說明
- Enter total current assets.
- Enter total current liabilities.
- View the ratio (>1 means assets cover short-term debt).
以流動負債固定為 HK$900,000 為例，不同流動資產對應的流動比率。傳統上不少行業以 1.5–2 倍為健康參考，但僅屬概略。
| 流動資產 (HK$) | 流動負債 (HK$) | 流動比率 |
|---|---|---|
| 900,000 | 900,000 | 1.00 倍 |
| 1,350,000 | 900,000 | 1.50 倍 |
| 1,500,000 | 900,000 | 1.67 倍 |
| 1,800,000 | 900,000 | 2.00 倍 |
理財情境案例
個案一:高流動比率也可能藏風險
一家貿易公司流動資產 HK$1,800,000、流動負債 HK$900,000，流動比率 = 2.0 倍，看似非常穩健。
但細看流動資產組成：存貨佔 HK$1,000,000 且部分滯銷，現金與應收帳款僅 HK$800,000。剔除存貨後速動比率只有 800,000 ÷ 900,000 ≈ 0.89 倍。
教訓：流動比率高不代表流動性好。若資產集中在難變現的存貨，急需現金時仍可能週轉困難。務必配合速動比率檢視資產質素。
個案二:比率低於 1 的週轉壓力
一家擴張中的小型零售商流動資產 HK$720,000、流動負債 HK$900,000，流動比率 = 0.8 倍，即流動資產不足以覆蓋短期負債。
由於零售收現快、存貨周轉高，若每日現金流入穩定，短期未必即時爆煲；但一旦銷售放緩或供應商收緊帳期，就需靠再融資或延遲付款應付。
這說明比率低於 1 未必等於危機，但屬明確警號，須結合現金流周轉速度與再融資能力綜合判斷。
常見問題
What current ratio is healthy?
No universal standard; industry varies widely. Traditionally ~1.5-2 is a rough reference, but fast-cash retail tolerates lower, capital-intensive needs higher. Compare with peers and your own trend, and read asset quality.
Is a higher ratio always better?
No. Too high may mean idle cash, piled inventory or uncollected receivables — low efficiency and opportunity cost. Aim for 'enough to cover short-term debt without wasting resources'. Read with quick and cash ratios.
What is the difference from the quick ratio?
Current ratio uses all current assets; quick ratio excludes slower-to-sell inventory (sometimes prepayments), keeping only cash, equivalents and receivables — more conservative. If current is high but quick is low, inventory likely dominates; check if it can sell.
How can Hong Kong SMEs improve the ratio?
On the asset side: speed receivables (shorter terms, early-pay discounts), clear slow inventory to cash, hold reasonable cash. On the liability side: refinance short-term into medium/long-term loans, negotiate longer supplier terms. HK trade finance and SME financing guarantee schemes help short-term周转, but weigh the added debt.
Does the ratio fluctuate seasonally?
Yes. It is a static snapshot; seasonal businesses (retail, toys, apparel) build inventory before peak (inventory up, cash down) then see receivables up, inventory down after — the ratio swings within the year. Compare at the same reporting date or use multi-period averages to avoid seasonal distortion.
