「有赚钱,不代表这项投资真的划算」
很多老板在评估一项投资时,最常问的是:
“这次带来了多少 Sales?”
“最后有没有赚钱?”
但真正应该问的是:
我投入的每 RM1,到底为公司带回多少回报?
这就是 Return on Investment,简称 ROI( #投资回报率)。
━━━━━━━━━━━━━━
ROI 的计算公式:
ROI =(投资收益 − 投资成本)÷ 投资成本 × 100%
举个简单的例子:
投资成本:RM10,000
投资收益:RM12,000
ROI:
(RM12,000 − RM10,000)
÷ RM10,000 × 100%
= 20%
意思是公司每投入 RM1,在收回本金后,额外赚了 RM0.20。
━━━━━━━━━━━━━━
不过,计算 ROI 时最容易犯的错误,就是直接把 Sales 当成投资收益。
假设公司花 RM10,000 做 Marketing,最后带来 RM30,000 Sales,并不代表公司就赚了 RM20,000。
因为当中可能还要扣除:
▪️ 产品或服务成本
▪️ Sales Commission
▪️ 执行及营运成本
▪️ Payment Gateway Fee
▪️ 退款及售后成本
▪️ 员工投入的时间和资源
所以:
Sales ≠ Profit
Sales 也不等于真正的投资回报。
如果相关成本没有计算进去,看到的 ROI 很可能只是一个表面上漂亮的数字。
━━━━━━━━━━━━━━
ROI 是不是越高越好?
一般来说,ROI 越高,代表投资回报越好。
但做商业决定时,不能只看一个百分比,还要一起考虑:
✅ 实际为公司赚了多少钱
✅ 需要多久才能收回投资
✅ Cash Flow 是否能够负担
✅ 投资涉及多大的风险
✅ 是否能够持续及扩大规模
一项 ROI 很高但只能做一次的小项目,不一定比一个 ROI 较低、却能长期扩大规模的项目更值得投资。
━━━━━━━━━━━━━━
ROI 不只可以用来评估广告,也可以用来衡量:
▪️ 购买新机器或系统
▪️ 聘请新员工
▪️ 开设新分行
▪️ 推出新产品
▪️ 员工培训
▪️ Marketing Campaign
真正有用的 Accounting,不只是记录公司花了多少钱。
更重要的是帮助老板看清:
这笔钱花下去后,到底有没有为公司创造足够的回报?
“Making money doesn’t necessarily mean the investment was worthwhile.”
When evaluating an investment, many business owners usually ask:
“How much Sales did this generate?”
“Did we make a profit in the end?”
But the more important question is:
For every RM1 invested, how much return did the company actually generate?
This is where Return on Investment ( ) comes in.
━━━━━━━━━━━━━━
📌 ROI Formula
ROI = (Investment Return − Investment Cost) ÷ Investment Cost × 100%
For example:
Investment Cost: RM10,000
Investment Return: RM12,000
ROI:
(RM12,000 − RM10,000)
÷ RM10,000 × 100%
= 20%
This means that for every RM1 invested, the company earned an additional RM0.20 after recovering the original investment.
━━━━━━━━━━━━━━
⚠️ One of the Most Common ROI Mistakes
The biggest mistake when calculating ROI is treating Sales as the investment return.
Suppose a company spends RM10,000 on Marketing and generates RM30,000 in Sales.
That does not mean the company made RM20,000 in profit.
You may still need to deduct:
▪️ Product or service costs
▪️ Sales commissions
▪️ Ex*****on and operating costs
▪️ Payment gateway fees
▪️ Refunds and after-sales costs
▪️ Employee time and resources
Therefore:
Sales ≠ Profit
Sales ≠ Actual Investment Return
If these costs are not taken into account, the ROI may look impressive on paper but fail to reflect the actual return.
━━━━━━━━━━━━━━
📊 Is a Higher ROI Always Better?
Generally, a higher ROI indicates a better return on investment.
However, when making business decisions, you shouldn't look at the percentage alone. You should also consider:
✅ How much actual profit the investment generates
✅ How long it takes to recover the investment
✅ Whether the Cash Flow can support it
✅ The level of risk involved
✅ Whether the investment can be sustained and scaled
An investment with a very high ROI but only a one-off opportunity may not necessarily be better than an investment with a lower ROI that can generate sustainable, scalable returns.

💡 ROI Can Be Used to Evaluate More Than Advertising
ROI can also help measure the effectiveness of:
▪️ Purchasing new machinery or software
▪️ Hiring new employees
▪️ Opening a new branch
▪️ Launching a new product
▪️ Employee training
▪️ Marketing campaigns
Good accounting isn't just about recording how much money a company spends.
More importantly, it helps business owners understand:
👉 After spending this money, did it actually generate enough value and return for the company?
