What Is Days Payable Outstanding?

Days Payable Outstanding (DPO) measures the average number of days a company takes to pay its suppliers.

In simple terms:

> How long does the company retain cash before paying suppliers?

Supplier credit can be an important part of working-capital management.

DPO Formula

A common formula is:

DPO = Average Accounts Payable ÷ Cost of Goods Sold × 365

Where appropriate, analysts may use purchases instead of COGS when purchase data is available.

Example

Suppose:

Opening accounts payable = ₹240 crore
Closing accounts payable = ₹300 crore
Annual COGS = ₹1,825 crore

Average accounts payable:

(₹240 + ₹300) ÷ 2 = ₹270 crore

DPO:

₹270 ÷ ₹1,825 × 365 = approximately 54 days

The company takes about 54 days to pay suppliers.

What Does a High DPO Mean?

A higher DPO means the company takes longer to pay suppliers.

This can be positive when it reflects:

Strong bargaining power
Favourable supplier terms
Efficient working-capital management

But a very high DPO can also indicate payment delays or financial pressure.

What Does a Low DPO Mean?

A lower DPO means suppliers are paid faster.

Possible reasons include:

Strong liquidity
Short supplier terms
Early-payment practices
Lower negotiating power

Again, context matters.

DPO Trend

Suppose:

| Year | DPO |

|---|---:|

| FY2024 | 42 days |

| FY2025 | 48 days |

| FY2026 | 57 days |

The increase could reflect improved supplier terms or could indicate that payments are being delayed.

Investors should investigate.

DPO and Cash Conversion Cycle

DPO is one component of the Cash Conversion Cycle:

Cash Conversion Cycle = DIO + DSO − DPO

A higher DPO, all else equal, reduces the number of days cash is tied up in the operating cycle.

Indian Equity Example

Suppose:

| Metric | Company A | Company B |

|---|---:|---:|

| DIO | 50 days | 55 days |

| DSO | 40 days | 45 days |

| DPO | 35 days | 70 days |

Company A CCC:

50 + 40 − 35 = 55 days

Company B CCC:

55 + 45 − 70 = 30 days

Company B has a shorter cash conversion cycle.

However, the investor should verify whether its higher DPO comes from strong supplier relationships or delayed payments.

DPO and Supplier Relationships

Persistently slow payments can eventually lead to:

Tighter supplier terms
Loss of early-payment discounts
Reduced supplier confidence
Potential supply disruptions

Therefore, a high DPO should not automatically be treated as a competitive advantage.

Advantages

Helps analyse supplier-payment behaviour
Useful for working-capital analysis
Helps explain cash-flow movements
Important component of the Cash Conversion Cycle

Limitations

Industry differences are large
COGS may not perfectly represent purchases
Seasonality can distort results
High DPO can have positive or negative explanations

Frequently Asked Questions

Is a high DPO good?

Not automatically. It can indicate bargaining power or efficient working capital, but it can also indicate delayed payments.

Does higher DPO improve cash flow?

An increase in accounts payable can temporarily retain cash in the business.

Why is DPO important?

It helps investors understand how supplier credit affects working capital and cash conversion.

Final Thoughts

DPO helps equity investors understand how a business manages supplier payments.

Use it with inventory days, receivable days, operating cash flow and the Cash Conversion Cycle.
