One of the biggest challenges when taking out a loan is the high interest rates charged by lending institutions. These interest rates can significantly increase the money you need to pay back and put an unfortunate dent in your finances.
However, if lenders view you as a trustworthy client with a high credit score and good financial profile, you can avail the loan at a better interest rate, known as the prime lending rate.
This article explores the prime lending rate’s meaning, the factors affecting it, and how it can affect the loans you borrow.
The Prime Lending Rate (PLR) is the interest rate lending institutions use as a base to determine the interest rate for their loan products.
You can define the prime interest rate as the lowest rate at which financial institutions lend money. It is used as a reference point to set interest rates for various variable-rate financial products such as mortgages and personal loans.
Changes in key policy rates by the Reserve Bank of India (RBI) influence the prime lending rate.
Commercial financial institutions offer prime lending rates to their most creditworthy consumers on short-term loan products, including variable-rate personal and business loans.
Consumers who benefit from the prime lending interest rate include people who have:
Conversely, consumers with a low credit score or a higher perceived risk may be charged a higher interest rate by lenders.
Prime lending rates in India are set according to the RBI guidelines. The RBI sets the base rate below which no lending institution can set its prime rate. The prime rate for a particular financial institution is set by its management according to various factors such as funding costs and operating expenses.
Various other factors, such as market conditions, inflation rates, global economic conditions, and currency exchange rates, can also impact the prime lending rate in India.
All these factors, in combination, determine the spread, which is the additional cost lenders consider beyond the Repo Rate. The prime lending rate added to the spread determines the interest rate for consumers.
Changes in the prime rate do not affect existing loans or lines of credit with fixed interest rates. This includes loans like student loans and mortgages, as well as credit cards issued with fixed rates.
The prime lending interest rate serves as a benchmark for lending rates, and it may affect personal loan interest rates. An increase in the prime lending rate may also increase personal loan interest rates, increasing the loan repayment amount.
Changes in the prime lending rate can thus affect the affordability and cost of borrowing these loans.
The base rate, introduced in July 2010, is the minimum interest rate set by the RBI for giving out loans. RBI controls the base rate to enhance transparency, keep the economy in check, and ensure that consumers are not charged discriminately.
The following table illustrates the differences between the prime lending rate and the base rate:
| Features | Prime lending rate | Base rate |
| Purpose | Serves as a reference point for financial institutions to set interest rates on loans for their most creditworthy consumers | Serves as a benchmark for financial institutions to calculate interest rates for various loans |
| Determinant | Influenced by changes in the RBI’s policy rates, credit risk, and market conditions | Influenced by the RBI’s monetary policy, economic conditions, and cost of funds |
| Flexibility | Typically set by the lending institutions as a fixed percentage above the RBI’s policy rate | Lending institutions are allowed to add a spread to the base rate to calculate the actual lending rate |
| Used for | Primarily used for loans offered to the most creditworthy consumers | Used for a wide range of loans, such as housing loans and MSME loans |
| Creditworthiness | Directly influences the interest costs of the most creditworthy consumers for loans with a prime interest rate | Influences interest costs for loans with variable interest rates tied to the base rate |
| Transparency | Provides a transparent benchmark for certain interest rates | Increases transparency in lending rates and ensures fair pricing |
| Adjustment frequency | Adjusted by lending institutions in response to changes in market conditions and the RBI’s policy rates | Adjusted by lending institutions according to changes in the economic conditions and the RBI’s policy rates |
| Regulation | Regulatory scrutiny ensures transparency and prevents discriminatory lending practices | Regulatory oversight ensures fair lending practices and adherence to RBI guidelines |
| Risk considerations | Considers the credit risk of lending funds to the most creditworthy consumers | Considers the overall economic risk and cost of funds for financial institutions |
In India, the PLR rate does not change on fixed dates. Banks update their PLR after reviewing market conditions, changes in funding costs, and the RBI’s policy. When interest rates in the economy rise or fall, banks may revise their PLR accordingly. Usually, these changes occur a few times a year, but there is no schedule. If inflation increases or the RBI changes its policy rates, banks may adjust the PLR to protect their margins.
Today, many new loans are linked to MCLR or external benchmarks. Thus, the impact of PLR rate changes is on older loans and some specific lending products.
Before taking a loan in India, it is vital to understand the differences between the PLR rate, Repo-linked rate, and MCLR. Each one affects your interest cost differently.
When it comes to understanding which loan is best for you, repo-linked ones can be a good choice. They offer faster benefits during rate cuts. MCLR is the next best option, while PLR is suitable only for older loans.
The following simple tips can help to get loan offers below the PLR rate in India:

The interest rate is the percentage that determines how much interest you will pay on a loan in addition to the principal amount. On the other hand, the prime rate is the base interest rate used by financial institutions to determine interest rates for loan products.
The prime rate is generally calculated by adding 3.0 percent to the federal funds rate. In India, the Marginal Cost of Funds Based Lending Rates (MCLR) or the Repo Rate is typically used as a benchmark for setting lending rates rather than the prime rate. The Repo rate is set by the RBI, while the MCLR is calculated according to the loan tenor and the lending institution’s cost of funds.
The prime lending rate in India is set by the Reserve Bank of India (RBI). By setting the minimum rates at which loans are given, the RBI keeps the economy in check and ensures that all customers are treated fairly.
In banking, PLR’s full form is Prime Lending Rate. It is the interest rate that banks charge when their most reliable and low-risk customers take loans. It acts as a reference rate for setting interest rates on various loans.
Previously, the Reserve Bank of India (RBI) influenced PLR guidelines. Now, individual banks determine their PLR based on funding costs, operating expenses, and risk. They also consider market conditions, business needs, and competition.
The interest rate of most loans is linked to the PLR rate. Thus, when PLR increases, EMIs for home and personal loans also increase. Similarly, when PLR drops, EMIs become lower for home and personal loans.
PLR is an older benchmark rate, mainly for existing loans. MCLR is a newer, more transparent system linked to the actual cost of funds for banks. It responds faster to changes in interest rates.
Yes, NBFCs and banks can have different PLR rates. This is because they set their PLR based on the cost of funds, risk profile, operating expenses, business model, and market position.
