Age of Money Calculation

The Age of Money (AOM) is a financial metric that measures the average time it takes for a company to convert its investments in inventory and accounts receivable into cash. It provides insights into a company's liquidity and cash conversion efficiency.

What is Age of Money?

The Age of Money is a key performance indicator used by financial analysts to evaluate a company's liquidity and cash conversion efficiency. It represents the average number of days it takes for a company to convert its investments in inventory and accounts receivable into cash.

Calculating the Age of Money helps businesses understand how efficiently they manage their working capital. A lower Age of Money indicates better liquidity and cash flow management, while a higher Age of Money may signal potential issues with receivables or inventory management.

Key Components

The Age of Money calculation typically includes:

Average inventory
Cost of goods sold (COGS)
Average accounts receivable
Average net credit sales

How to Calculate Age of Money

The Age of Money is calculated using the following formula:

Formula

Age of Money = (Average Inventory + Average Accounts Receivable) / (Cost of Goods Sold + Net Credit Sales)

Where:

Average Inventory = (Beginning Inventory + Ending Inventory) / 2
Average Accounts Receivable = (Beginning Receivables + Ending Receivables) / 2
Cost of Goods Sold (COGS) = Total cost of goods sold during the period
Net Credit Sales = Total sales on credit during the period

The result is typically expressed in days. A lower Age of Money indicates better cash conversion efficiency, while a higher Age of Money may suggest delays in receiving payments or managing inventory.

Interpretation of Results

Interpreting the Age of Money requires understanding industry benchmarks and comparing the result with competitors. Generally:

Industries with high inventory costs (like manufacturing) typically have higher Age of Money values.
Service industries often have lower Age of Money values due to faster receivables collection.
An Age of Money below 30 days is generally considered good.
Values between 30-60 days may indicate room for improvement.
Values above 60 days may suggest liquidity concerns.

Industry Benchmarks

Common Age of Money ranges by industry:

Manufacturing: 40-80 days
Retail: 20-40 days
Technology: 15-30 days
Financial Services: 10-20 days

Worked Example

Let's calculate the Age of Money for a company with the following data:

Beginning Inventory: $50,000
Ending Inventory: $60,000
Beginning Receivables: $30,000
Ending Receivables: $40,000
Cost of Goods Sold: $120,000
Net Credit Sales: $200,000

Step 1: Calculate Average Inventory

(50,000 + 60,000) / 2 = $55,000

Step 2: Calculate Average Accounts Receivable

(30,000 + 40,000) / 2 = $35,000

Step 3: Apply to Age of Money Formula

(55,000 + 35,000) / (120,000 + 200,000) = 90,000 / 320,000 = 0.28125 days

Convert to days: 0.28125 × 365 ≈ 102.5 days

Result Interpretation

An Age of Money of approximately 102.5 days suggests the company has significant delays in converting investments into cash. This may indicate inefficiencies in inventory management or receivables collection that should be investigated.

FAQ

What is a good Age of Money score?

A good Age of Money score varies by industry. Generally, values below 30 days are considered excellent, while values above 60 days may indicate liquidity concerns that should be addressed.

How often should Age of Money be calculated?

The Age of Money should be calculated quarterly to monitor trends in liquidity and cash conversion efficiency over time.

Can Age of Money be negative?

No, the Age of Money cannot be negative. A negative result would indicate an error in the calculation or input data.

How does Age of Money compare to Days Sales Outstanding?

Age of Money and Days Sales Outstanding (DSO) are related metrics. Age of Money provides a more comprehensive view by including both inventory and receivables, while DSO focuses solely on receivables.
