輸入資料
計算結果
重點速覽：Average collection period = accounts receivable / net credit sales x period days (usually 365). It measures how long credit sales stay uncollected. Shorter is generally better; compare with your credit terms. Reciprocal of receivables turnover (net credit sales / receivables).
計算公式
平均收款期 = 應收帳款 ÷ 年賒銷淨額 × 期間天數。
全年通常取 365 天作為期間天數。
$$\text{平均收款期} = \dfrac{\text{應收帳款}}{\text{年賒銷淨額}} \times \text{期間天數}$$$$\text{平均收款期} = \dfrac{365}{\text{應收帳款周轉率}}$$使用說明
- Enter the accounts receivable balance.
- Enter net credit sales for the period.
- Confirm the period days (365 for a year) and view the collection period.
應收帳款 HK$500,000 時，不同年賒銷淨額對應的平均收款期
| 應收帳款 | 年賒銷淨額 | 平均收款期 | 解讀 |
|---|---|---|---|
| HK$500,000 | HK$5,000,000 | 36.5 天 | 賒銷高、收款相對快 |
| HK$500,000 | HK$3,650,000 | 50 天 | 本工具預設值 |
| HK$500,000 | HK$2,500,000 | 73 天 | 賒銷低，收款期拉長 |
| HK$300,000 | HK$3,650,000 | 30 天 | 帳款少，回款快 |
| HK$700,000 | HK$3,650,000 | 70 天 | 帳款多，佔壓資金 |
理財情境案例
案例一：計算平均收款期
某公司應收帳款 HK$500,000，全年賒銷淨額 HK$3,650,000。平均收款期 = 500,000 ÷ 3,650,000 × 365 = 50 天。
代表平均要 50 天才收到客戶付款。若公司信用政策是『月結 30 天』,50 天顯示實際收款比約定慢了 20 天，需檢視催收流程與客戶付款習慣。
案例二：收款期過長的財務代價
若上述公司收款期由 50 天惡化到 73 天 (賒銷不變、應收升至 HK$730,000)，等於多綁住 23 天的營收約 HK$230,000 在應收帳款上。
這筆錢若需靠銀行透支周轉，以年息 8% 計，一年利息成本約 HK$18,400。可見收款效率不只是會計數字，更直接牽動實際的融資成本與現金流風險。
常見問題
What is the difference from A/R Days?
They measure the same idea. A/R Days often uses total revenue as a convenient denominator; the average collection period strictly uses net credit sales. Since only credit sales create receivables, net credit sales is the more accurate base. Keep the basis consistent when comparing.
Is a shorter period always better?
Generally yes — faster cash, healthier cash flow, lower bad-debt risk. But tightening credit too hard may hurt sales and customer relations. Aim to keep the period around or just below your credit terms.
How does it relate to receivables turnover?
They are reciprocals. Receivables turnover = net credit sales / receivables (cycles per year); average collection period = 365 / turnover (days per cycle). Higher turnover means fewer days.
Why net credit sales not total revenue?
Only credit sales generate receivables, so dividing by net credit sales gives the true collection time. Using total revenue (which includes cash sales) overstates the days. Use credit sales if available; otherwise state the approximation.
How does it fit the cash conversion cycle?
It is the 'collection' leg: CCC = DIO (inventory days) + DSO (this period) - DPO (payables days). Shorter collection means revenue turns to cash faster, easing working-capital pressure. Improve it via early-payment discounts, stricter credit checks and active follow-up.
