Having a great business idea is exciting. But before putting your money into it, there is one thing that matters even more: making sure the business makes financial sense.

You already have the concept, the products, the location, maybe even the brand name.

So, is it time to find the capital and start?

Not necessarily.

One common mistake among new business owners is choosing a business based on how much capital they have, rather than asking whether the business is financially viable.

Let’s say you have Rp100 million in capital.

The question isn’t:

“What business can I start with Rp100 million?”

A better question is:

“If I invest Rp100 million into this business, can it generate profit and maintain healthy cash flow?”

Because capital is only the starting point.

Don’t Just Calculate the Cost of Opening

When calculating startup capital, many people focus only on the expenses they can see at the beginning:

  • Rent
  • Renovation
  • Equipment
  • Initial inventory
  • Branding
  • Business permits

But once the business opens, the expenses continue.

Employee salaries, electricity, raw materials, marketing, maintenance, loan payments, and other operating costs still need to be paid—even when sales are below expectations.

That means your initial capital should not only be enough to open the business, but also support the business until it can generate healthy cash flow.

So, How Much Do You Actually Need to Sell?

This is where many business plans fall short.

Imagine a coffee shop requires an initial investment of Rp100 million.

Knowing the investment amount alone isn't enough.

You also need to know:

How many cups need to be sold every day?

How much revenue is needed each month?

What is the profit margin on each product?

How much does the business spend every month?

When will the business break even?

And perhaps most importantly:

If sales reach only 70% of the target, can the business still survive?

Without these calculations, starting a business becomes more about assumptions than planning.

A Busy Business Isn't Necessarily a Healthy Business

Imagine a business generating Rp80 million in monthly revenue.

Sounds great, right?

But then you break down the numbers:

Cost of Goods Sold: Rp35 million
Salaries: Rp15 million
Rent: Rp10 million
Marketing: Rp5 million
Other Operating Costs: Rp10 million

That leaves only Rp5 million in profit.

Add loan payments, taxes, reinvestment needs, or a decline in sales, and the business's financial position can change quickly.

That’s why revenue alone isn't enough to measure the health of a business.

You need to understand the relationship between sales, costs, profit, investment, and cash flow.

Before Spending Your Capital, Calculate These 5 Things

1. Initial Investment

How much money do you actually need to start the business?

Don't just calculate the cost of opening. Consider assets, initial inventory, renovation, equipment, and other startup requirements.

2. Operating Costs

How much does the business need to spend every month to keep operating?

3. Revenue Projection

How much revenue can you realistically generate based on your pricing, capacity, and target customers?

4. Profitability

After all expenses are taken into account, how much profit is actually left?

5. Cash Flow

Does the business have enough cash to cover its operating needs month after month?

These five areas give you a more complete picture of your business's financial condition.

Don’t Build a Business Based on Feeling Alone

A good business idea matters.

Experience matters.

Understanding your market matters.

But when it comes to making a decision that involves your money, the numbers need to speak too.

Financial planning helps you understand the business before making major decisions.

With proper calculations, you can estimate your capital requirements, project revenue and expenses, understand potential profitability, and see how your cash flow may develop over time.

Calculate Your Business Before You Start

You don't have to wait until your business is running to find out whether the numbers make sense.

Before asking, “When should I start?” there may be a more important question: “Is this business financially ready to start?”
