How to calculate DPO
Days payable outstanding tells you how long, on average, you hold on to cash before paying suppliers. Divide average accounts payable by cost of goods sold for the period, then multiply by the days in that period.
What you owe suppliers for goods and services already received. Add opening and closing trade payables (sundry creditors) from the balance sheet or AP ageing and divide by two.
Example: (₹2.8 Cr + ₹3.2 Cr) ÷ 2 = ₹3 CrCOGS comes from the profit and loss statement and is the textbook base. Purchases come from the purchase register and fit better when inventory moved a lot or many payables are for services.
Example: COGS for October to December = ₹6 CrThe length of the period your COGS or purchases figure covers. Use 30, 90 or 365, or the exact days for a half year or a broken period.
Example: one quarter = 90 daysThe standard definition used by analysts and in most annual reports. Easy to pull, and comparable with peers.
Average AP ÷ COGS × daysCloser to what you actually bought on credit. Use it when inventory swung sharply or payables include large service and capex bills.
Average AP ÷ credit purchases × daysSome teams work out AP turnover first and convert it to days. It gives the same answer as the purchases basis.
Days ÷ (purchases ÷ average AP)| Opening payables | ₹2,80,00,000 |
| Closing payables | ₹3,20,00,000 |
| Average payables | ₹3,00,00,000 |
| COGS in the quarter | ₹6,00,00,000 |
| DPO | 45.0 days |
- Average the payables: (2.8 crore + 3.2 crore) ÷ 2 = 3 crore
- Divide by COGS: 3 crore ÷ 6 crore = 0.5
- Multiply by the days: 0.5 × 90 = 45 days
- Compare with your terms. On 60-day terms you are paying 15 days early, which may be worth it only if you earn a discount
What is a good DPO, and the MSME 45-day rule
A good DPO sits close to the terms you agreed with suppliers. Paying much earlier gives away free financing, and paying much later costs you goodwill, discounts and in India possibly a tax deduction.
| Industry | Typical DPO | Why it lands there |
|---|---|---|
| Retail and eCommerce | 35 to 70 days | Large buyers negotiate long terms with brands and distributors |
| FMCG and consumer goods | 45 to 80 days | Scale purchasing of packaging and raw material |
| Manufacturing | 50 to 90 days | Long supplier chains and milestone-based payments |
| Logistics | 25 to 50 days | Fuel, tolls and fleet owners expect quick payment |
| Enterprise SaaS | 20 to 45 days | Cloud and software vendors bill monthly on short terms |
| Pharma and healthcare | 60 to 110 days | API and packaging suppliers often accept long credit |

| India rule | Limit | What it means for DPO |
|---|---|---|
| MSMED Act, section 15 | 45 days max | Pay micro and small suppliers by the agreed date, which cannot be more than 45 days from acceptance. With no written agreement, the limit is 15 days. |
| MSMED Act, section 16 | 3x bank rate | Late payment attracts compound interest with monthly rests at three times the RBI bank rate, and section 23 says that interest is not tax deductible. |
| Income-tax section 43B(h) | 31 March test | An MSE bill still unpaid beyond the section 15 limit at year end is disallowed as an expense that year and allowed only when you pay it. |
Section 43B(h) was added by the Finance Act 2023 and applies from tax year 2023-24. DPO is an average, so check individual MSE invoices in your AP ageing, not just this number.

How to improve DPO without hurting suppliers
The goal is not the highest possible DPO. It is paying every supplier on the right day: never late, and never early unless early pays you back.
Many teams pay the moment an invoice is approved. Scheduling payment runs on due dates alone can add several days of DPO with no change in terms.
Terms of 2/10 net 30 work out to about 37% a year. If your cost of funds is lower, take the discount. If not, pay on day 30.
Tag Udyam-registered suppliers in the vendor master and route their bills on a 45-day clock, so a longer DPO elsewhere never spills over to them.
Focus on your top 20 suppliers by spend. Moving a few of them from 30 to 45 days changes DPO more than chasing hundreds of small vendors.
Invoices stuck in approval often get paid late and in a rush. A clean three-way match keeps payment timing in your control.
Your cash conversion cycle depends on both. If customers pay in 60 days and you pay in 30, you are funding the gap from your own cash.
If you want payment runs that follow due dates and MSE limits automatically, Bluecopa's procure-to-pay automation schedules approvals and payments around each supplier's terms.
Frequently asked questions
Divide average accounts payable by cost of goods sold for the period and multiply by the number of days in that period. With ₹3 crore of average payables and ₹6 crore of quarterly COGS, DPO is 0.5 × 90 = 45 days.
COGS is the standard choice and makes peer comparison easy. Purchases are more accurate when inventory levels changed a lot during the period or when a big part of payables relates to services and capex that never pass through COGS.
A higher DPO keeps cash in the business for longer, which helps working capital. It turns bad when you pay beyond agreed terms, lose early-payment discounts, or breach the 45-day limit for micro and small suppliers.
Under section 15 of the MSMED Act, a buyer must pay a micro or small enterprise by the agreed date, which cannot be more than 45 days from accepting the goods or services. Without a written agreement, the limit is 15 days. Traders registered on Udyam are generally not covered for this purpose.
If an MSE bill is still unpaid beyond the section 15 limit on 31 March, the expense is disallowed for that year and allowed in the year you actually pay. Interest you owe under section 16 is never deductible.
DSO measures how long customers take to pay you, and DPO measures how long you take to pay suppliers. Cash conversion cycle combines them with inventory days: DIO plus DSO minus DPO.
