How Big is Your Gap?
Like many professionals, I try to leave my work at the office to make my personal time with the family as free of work-related concerns as possible. However, one particular “business” topic that occasionally comes up, especially during the holidays, is our family’s “cash gap.” Basically, the cash gap is the number of days between when we spend money buying presents, and when I get paid next. You can see why this is important to me! And, just like in my home, an understanding of the cash gap is absolutely critical for your business as well. For small businesses, especially, understanding your cash gap is an important part of what you need to know to properly fund your company and operate profitably.
What is the Cash Gap?
The cash gap, also known as the “Cash Conversion Cycle” (CCC), measures the time between when you need to write a check for your payables or payroll and when you receive payment of the invoices for the items you’ve sold. It is a powerful measurement of how well your company is using its working capital. The formula for calculating the cash gap is:
Days’ Inventory + Days’ Receivables – Days’ Payables = Cash Gap
Each piece of the above formula is determined by the following calculations:
Some important notes:
Why is the cash gap so important?
You need money to run your business, right? If you don’t pay your staff on time, your employees may decide to not come to work tomorrow. If you don’t pay your suppliers on time, they may decide to not ship you critical inventory items. The cash gap represents the amount of time that the company is “out” of money because of its normal sales activity. When the company is out of money, it must find it from other sources in order to continue operating. In other words, the cash gap is a financial shortfall that the company must fill using other sources of money, like short term borrowing. And, as you already know, all money carries a cost, just like interest expense on a line of credit or the opportunity cost of funds that could be used for other purposes. As a result, an excessive or poorly managed cash gap leads to extra costs and could have a significant negative effect on profitability and cash flows, while at the same time undermining a company’s ability to grow.
The cash gap, specifically, is expressed as a number of days. However, its impact is felt in real dollars, including interest, which company has “tied up” in working capital. Because of this, understanding your company’s cash gap is an important part of many decisions that must be made when operating your business, including:
And, it is VERY important to monitor your company’s cash gap and its components across multiple periods. Because your company’s cash is at stake, as a business owner, you certainly want to know how and why these critical pieces of your business are changing over time and take appropriate action when required.
What can we do about it?
A forward thinking financial manager will try to minimize the company’s cash gap when all other things are held constant. When effectively managed, reducing the cash gap can have a positive influence on profitability and cash flow, and provide money that can be used elsewhere in the business.
A reduction in the cash gap can be accomplished by one or more of the following:
What About A Negative Cash Gap?
Some companies are able to operate with a negative cash gap. This means that the company collects cash from customers before they have to pay their suppliers. This condition is often found in consumer goods industries where cash is usually collected at the time of the sale. Companies like Amazon, Dell and Walmart have been very successful at using the negative cash gap to their advantage. They collect their money at the time that the sale is made, and often stretch out their payables 60 or even 90 days.
A negative cash gap can be a very positive thing, depending on the company and/or industry. A negative cash gap can be good for profitability, because the company probably doesn’t need to borrow as much money to finance the shortfall. However, beware of the cautions above in relation to how you operate your business. A negative cash gap may or may not be a realistic expectation for your business.
So, what is the best cash gap to have?
As is the case with many financial metrics, the best answer is highly dependent on a number of factors. The best cash gap for any given company is a careful balance of company strategy, industry, profitability and operational management. Achieving the best balance for your company begins with understanding your business’ current state and identifying opportunities for improvement. That is why, as mentioned above and as with many business Key Performance Indicators (KPI’s), it’s important to not only measure the company’s performance, but to track it over time. Is your Cash Gap increasing or shrinking? Did the change occur because of something that you did, or is it just moving around on its own? Your company’s money must be actively managed, and not left to arbitrary changes of your business’ marketplace.
