What it means
In everyday business language the word is used two ways. Personal and institutional finance uses it for assets held in a portfolio, while corporate finance uses it for capital projects, so a factory upgrade and a holding of government bonds are both investments in their own context.
The accounting distinction is worth understanding. Money spent on something consumed immediately, such as this month's advertising, is an expense, whereas money spent on something that will deliver value across several years is capitalised and appears as an asset on the balance sheet.
Every investment involves three variables: the amount committed, the expected return, and the risk that the return does not arrive. Any serious assessment has to weigh all three, because a high headline return means little if the probability of getting it is low.
Businesses evaluate investments by comparing expected cash flows against the cost of the money being used. If a project returns 9% and the company's funding costs 11%, it destroys value even though the return is positive in isolation.
Time also matters, because a dollar received in five years is worth less than a dollar today. That is why discounted measures such as net present value are generally preferred over simple ratios when the cash flows are spread over several years.
In practice
Real-world examples.
Example
A dental practice spends $95,000 on a digital scanner that cuts appointment times and allows two extra patients a day. The partners treat it as an investment because the additional fee income is expected to repay the machine within three years.
Example
A pension fund allocates $12,000,000 to an index-tracking equity fund and $8,000,000 to corporate bonds. Both are investments, but they sit at different points on the risk scale and are held for different reasons within the same portfolio.
Example
A software firm capitalises $640,000 of development costs on a new module because the work creates an asset expected to earn subscription revenue for several years. The team's routine bug fixing, by contrast, is expensed as incurred.
Formula
Calculation
Return on investment = (total gain - cost of investment) / cost of investment
Payback period = cost of investment / annual cash benefit
A packaging company buys an automated labelling machine for $180,000. The machine removes two shifts of manual handling and reduces waste, producing a measured saving of $54,000 a year, and it is expected to run for five years before needing replacement.
Total benefit across the life is 5 x $54,000 = $270,000. Return on investment is ($270,000 - $180,000) / $180,000 = $90,000 / $180,000 = 50% over the five years.
The payback period is $180,000 / $54,000 = 3.33 years, which means the company recovers its outlay in the fourth year and the final year and a half is clear benefit. Note that this simple version ignores the time value of money, so a full appraisal would discount the annual savings before deciding.Case study
Seen in the real world.
The following is a fictional, illustrative example. Cranmore Bakeries, an invented regional bakery, faced two competing proposals at its January board meeting. The first was a $180,000 automated labelling line saving $54,000 a year; the second was a $180,000 marketing campaign the sales director believed would lift revenue by $300,000 in a single year.
The finance manager laid the two side by side. The equipment generated a 50% return across five years and paid back in 3.33 years, with savings that would continue whether or not sales grew, while the campaign's $300,000 of revenue carried only a 22% contribution margin, worth about $66,000 of actual profit and none of it repeatable without spending again.
In this illustrative case the board funded the equipment and cut the campaign to $60,000 as a test. The wider lesson the fictional business took away was that calling something an investment does not make it one; the label only fits when the benefit genuinely outlasts the spending.
Watch out
Common mistakes.
- Describing any large piece of spending as an investment to make it sound prudent, when the benefit is consumed within the same period and it is simply a cost.
- Judging investments on return alone without asking how much risk was taken to earn it or how long the money is locked away.
- Ignoring the money already spent when deciding whether to continue a project, since past outlay is sunk and only future cash flows should drive the decision.
Questions
People also ask.
What is the difference between an investment and an expense?
An investment creates value that lasts beyond the current period and sits on the balance sheet, while an expense is consumed now and hits the profit and loss account immediately.
Is a house an investment?
It can be, if it produces rent or rises in value, but a home you live in also carries running costs and is best thought of as part shelter, part asset.
How do I compare investments with different lifespans?
Use a discounted measure such as net present value or an annualised return, since raw totals unfairly favour whichever option runs longest.
