How Are Interest Rates Decided? Factors You Should Know

If you're planning to take a loan, whether for personal needs or business purposes, one of the most important things to understand is how interest rates work. The interest rate is the cost of borrowing money, and even a small change in the rate can make a big difference in your total repayment.

But how are interest rates determined? Why do different people and businesses get different rates for similar loans? In this guide, we’ll break it down in a simple, easy-to-understand way, especially for small business owners and individual borrowers in India.

Creditworthiness: Your Financial Reputation Matters

One of the biggest factors that influences interest rates is your creditworthiness. This refers to how likely you are to repay the loan on time, based on your financial history.

Lenders usually check:

• Your credit score
• Past repayment history
• Existing debts
• Income level
• Business performance (for business loans)

A higher credit score or a strong business track record means you're seen as less risky. So, you may get lower business loan interest rates. On the other hand, if your credit history has delays or defaults, the lender may charge a higher rate to cover the risk.

Type of Loan: Secured or Unsecured Makes a Difference

The loan type also plays a key role in deciding your interest rate. Loans can be broadly classified into:

Secured Loans

These loans are backed by collateral-like property, equipment, or fixed deposits. Because the lender has security, the interest rate is usually lower.

Unsecured Loans

These are loans without any collateral. Since they carry more risk, the business borrowing rates or personal loan rates tend to be higher.

For example, if you're applying for a business loan with property as security, you'll likely get a better rate compared to an unsecured loan with no asset backing.

Loan Amount: Bigger Loans, Bigger Risk?

Yes, the loan amount matters. Larger loans often involve greater risk for the lender, which means they may either increase the interest rate or require stricter eligibility checks.

However, in some cases, high-value loans with strong collateral and a good credit history may even attract slightly lower interest rates, especially if you're seen as a reliable borrower.

So, the relationship between loan amount and interest rate isn’t always one-directional. It depends on your overall profile and how well your business is performing.

Repayment Terms: Longer Loans Can Cost More

Another key factor that decides your interest rate is the repayment structure. This includes:

• Loan tenure (short-term vs long-term)
• Frequency of repayments (monthly, quarterly, etc.)
• Whether you choose fixed or floating rates

Longer loan durations may come with slightly higher rates because the lender’s money is locked in for a longer time. However, the EMIs may be lower since the amount is spread across more months.

Also, with floating interest rates, your repayments may go up or down depending on market conditions. With fixed rates, your EMIs stay the same throughout the tenure, offering better predictability.

Understanding your repayment plan also helps answer another common question: Interest is always calculated on which value? The answer depends on the loan type. In most business and personal loans, interest is calculated on the outstanding principal, i.e., the amount yet to be repaid. This means that as your principal reduces over time, your interest portion in the EMI also goes down.

Industry Health: How Your Business Sector Influences Rates

If your business receives payments on a delayed basis but needs to pay vendors or salaries on time, an overdraft provides instant liquidity.

For instance:

• Sectors with stable cash flows like FMCG or IT may get better rates.
• Seasonal or high-risk sectors like hospitality, agriculture, or startups may be charged higher rates due to unpredictable earnings.

Business Nature: Sector and Type Can Influence the Rate

Apart from industry health, your business type and structure also impact the interest rate:

• Sole proprietors might get different rates than private limited companies.
• New businesses may face higher rates due to a lack of past records.
• Well-established firms with regular turnover and tax filings often get more competitive rates.

Also, if your business has availed loans in the past and repaid them responsibly, it builds your credit profile, improving your chances of getting lower business loan interest rates in future.

Final Thoughts: Make Informed Borrowing Decisions

So, how are interest rates determined? It’s not a random number. It depends on a combination of factors, including your credit profile, loan type, amount borrowed, repayment period, business health, and the nature of your industry.

Whether you are applying for a business loan or personal loan, understanding these factors can help you negotiate better, plan smarter, and reduce your overall borrowing cost.

And remember, while low interest rates are important, they shouldn’t be the only factor. Always consider the total cost of the loan, including fees, processing charges, and repayment flexibility.
