If you have ever applied for a loan from a Nepali bank, you have likely heard the term “Base Rate.” Understanding what the Base Rate is and how it is calculated can save you thousands of rupees over the life of your loan — because it is the foundation on which all loan interest rates in Nepal are built.
What Is Base Rate?
The Base Rate is the minimum interest rate below which a bank or financial institution in Nepal cannot lend money to its customers (with a few exceptions specified by NRB). It is calculated by each BFI individually based on their cost of funds, operating expenses, and required profit margin, and it must be approved and published in compliance with NRB directives.
In simple terms: Your loan rate = Base Rate + Premium (spread)
The “premium” or spread reflects your credit risk, loan type, and tenure. Home loans typically carry a lower premium than personal loans because they are secured assets.
How Is Base Rate Calculated in Nepal?
Per NRB’s unified directive, the Base Rate is calculated using the following components:
- Cost of Funds (CoF): The weighted average interest rate a bank pays on its deposits.
- Operating Cost: Administrative and staff costs as a percentage of average total assets.
- Cash Reserve Ratio (CRR) cost: The cost of keeping mandatory reserves at NRB.
- Return on Equity (RoE): The minimum profit margin required.
This means banks with lower deposit costs naturally have a lower Base Rate — which is why large commercial banks (who attract cheaper CASA — Current Account Savings Account — deposits) often have the lowest base rates.
Why Does the Base Rate Matter for Borrowers?
If you have a floating-rate loan in Nepal, your EMI changes whenever the bank revises its Base Rate. A 0.5% increase in base rate on a NPR 50 lakh home loan over 20 years can increase your total interest cost by over NPR 5 lakh.
This is why comparing Base Rates before selecting your lender is just as important as comparing the offered interest rate. Visit our Base Rate page to see the latest quarterly Base Rates of all commercial banks in Nepal.
Base Rate vs. Lending Rate: What’s the Difference?
| Factor | Base Rate | Lending Rate |
|---|---|---|
| Definition | Minimum floor rate set by each BFI | Actual rate charged to borrower |
| Set by | Each BFI based on NRB formula | BFI + credit risk premium |
| Changes | Quarterly (typically) | Follows base rate revisions |
| Transparency | Published on bank websites | Stated in loan agreement |
Which Bank Has the Lowest Base Rate in Nepal?
Base Rates vary across BFIs and are updated quarterly. Generally, large commercial banks like Nabil Bank, NIC ASIA, and Global IME have among the lowest base rates due to their lower cost of funds. Check our live Base Rate tracker for the most current figures.

Frequently Asked Questions
Can a bank charge below its Base Rate?
Generally no. NRB prohibits lending below the Base Rate. Exceptions exist for priority sector loans (agriculture, energy, export) which NRB subsidizes.
How often do Base Rates change in Nepal?
BFIs typically review and publish their Base Rate quarterly. However, they can revise it more frequently if their cost of funds changes significantly.
Does a lower Base Rate mean a better bank for borrowing?
It is one factor. Also compare the premium charged above base rate, processing fees, prepayment penalties, and overall service quality before choosing your lender.
