How Much to Borrow: Calculating Your Capital Requirement
 
October 2, 2025

One of the most critical steps in preparing to apply for a business loan is determining how much capital your SME actually needs. Borrowing too little may leave you underfunded, while borrowing too much can strain your cash flow and increase your financial risk. In this article, we’ll walk you through how to assess your capital requirements accurately, so you can borrow with confidence and clarity.

Why It’s Important to Get the Amount Right

Lenders want to see that you’ve done your homework. A well-calculated loan amount shows that you:

  • Understand your business needs
  • Have a clear plan for how the funds will be used
  • Are capable of repaying the loan responsibly

It also helps you avoid over-leveraging your business or taking on unnecessary debt.

Step 1: Define the Purpose of the Loan

Start by identifying the specific reason you’re seeking financing. Common purposes include:

  • Purchasing inventory or raw materials
  • Hiring staff or covering payroll
  • Upgrading equipment or technology
  • Expanding to a new location
  • Bridging cash flow gaps

Each purpose will have different cost structures and repayment timelines, which will influence how much you need to borrow.

Step 2: Break Down the Costs

Once you’ve defined your purpose, list all associated costs. Be as detailed as possible.

Example: Expanding a retail store

Item Amount (S$)
Renovation and fit-out
S$30,000
Inventory
S$20,000
Marketing
S$10,000
Staff salaries (3 months)
S$15,000
Contingency buffer (10%)
S$7,500
Total capital requirement
S$82,500

Step 3: Consider Existing Resources

Before finalizing the loan amount, assess what you can fund internally. This includes:

  • Cash reserves
  • Revenue from operations
  • Grants or subsidies
  • Trade credit from suppliers

Example: If you can cover S$30,000 from internal funds, you only need to borrow S$52,500.

Step 4: Align with Repayment Capacity

Use your cash flow projections to determine how much you can realistically repay each month. This will help you choose a loan amount and tenure that won’t overburden your business.

💡 Tip: Many lenders recommend that loan repayments should not exceed 30–40% of your monthly net cash flow.

Step 5: Add a Contingency Buffer

Unexpected costs are common in business. Add a 5–15% buffer to your capital requirement to account for delays, price increases, or emergencies.

Step 6: Match the Loan Type to the Need

Different financing tools suit different capital needs:

  • Term loansfor fixed, one-time investments
  • Credit linesfor ongoing or unpredictable expenses
  • Invoice financingfor short-term cash flow gaps
  • Microloansfor small, urgent needs

Choosing the right structure ensures you’re not overpaying for flexibility you don’t need, or locking yourself into rigid terms.

Conclusion: Borrow Smart, Grow Strong

Calculating your capital requirement isn’t just about numbers, it’s about aligning your financing with your business strategy. By taking a structured approach to determining how much to borrow, you’ll improve your chances of loan approval, avoid unnecessary debt, and set your SME up for sustainable growth.
