1. What is Floating Interest Rate?
Floating interest rate is a type of interest rate that can change over time, depending on external factors such as the bank's base interest rate or the economic situation. Unlike fixed interest rates, floating interest rates will change according to market factors, creating flexibility in loans and savings. Therefore, borrowers or depositors need to understand how this type of interest rate works to be able to manage their personal finances more effectively.
Basics of Floating Interest Rates
Floating interest rates are often applied in long-term loans or term deposits. This interest rate is not fixed but is periodically adjusted based on a reference index (for example, the State Bank's base interest rate or the interbank interest rate index). Each bank will specify the spread for their floating interest rate.
Popular applications:
- Bank loan: Floating rate loans are commonly used for home loans, long-term consumer loans, or auto loans.
- Deposit: In floating interest rate deposit products, depositors will receive interest rates that fluctuate over time, depending on market changes.

2. What is Floating Interest Rate Spread?
Floating interest rate spread is an important factor that helps determine the degree of fluctuation of floating interest rates in financial transactions. It indicates the range in which the interest rate can change during the contract period, and is calculated by adding or subtracting a percentage from the base rate or reference interest rate index used by the bank. This margin can be a fixed number or adjusted over time depending on the agreement between the bank and the customer.
How Floating Rate Spreads Work
The floating rate margin helps customers and banks determine how much their interest rates will fluctuate. When the base rate changes, your floating rate changes, but the margin determines how much it will fluctuate. If the margin is +2%, for example, your interest rate will always be 2% above the base rate, regardless of whether the base rate changes.
With this method, customers can better understand the level of risk they face when borrowing or saving with floating interest rate. When the bank or market base rate changes, the spread determines the fluctuation in interest rate that the customer must pay or receive.
Illustration:
Suppose you borrow money from a bank at a base rate of 6% and the floating interest rate margin is +2%. Then your floating interest rate will be calculated as follows:
Floating interest rate = Base interest rate + Interest rate margin
Applicable: Floating interest rate = 6% + 2% = 8%
This means you will have to pay interest rate 8% for your loan, and this interest rate can change according to market fluctuations. If the bank's base rate changes in the future, your floating interest rate will also change, but always with a margin +2%.
The Impact of Floating Interest Rate Margin on Financial Management
Floating interest rate spreads play an important role in managing financial risk when borrowing or saving. For borrowers, understanding the spread helps them predict future borrowing costs, even if the base rate changes. For depositors, understanding the spread also helps them optimize the return on their savings over the term of the deposit.
Real life example:
- Bank base interest rate: 5%
- Interest rate spread: +1.5%
The floating interest rate in this case would be 6.5% (5% + 1.5%), and if the bank's base rate changes to 6% next month, then floating interest rate Yours will automatically increase. 7.5% (6% + 1.5%). This helps customers predict in advance the interest rate that may change according to market fluctuations.
However, if the base rate falls to 4% next month, floating interest rate your will decrease 5.5% (4% + 1.5%), which helps reduce borrowing costs or increase profits from savings.

3. What is a Floating Interest Rate and How is it Different from a Fixed Interest Rate?
Floating interest rate and fixed interest rate are two common forms of interest in financial transactions. Each has its own characteristics and applications, affecting your borrowing costs and savings returns. Here is a comparison table between them:
| Characteristic | Floating Interest Rate | Fixed Interest Rate |
| Fluctuation | Market changes (base rate, inflation) | No change during loan or deposit term |
| Flexible | Flexible, adaptable to external factors | Fixed, predictable costs and profits |
| Advantage | Can save costs when interest rates fall | Ensure financial stability, not affected by the market |
| Disadvantages | Costs increase as interest rates rise | Cannot take advantage of falling market interest rates |
| Application | Often used for long-term loans and long-term savings. | Often used for short-term loans, savings with stable plans |
- Floating interest rate: Offers flexibility and the opportunity to save when interest rates fall, but can increase costs if market interest rates rise.
- Fixed interest rate: Provides stability, making it easier to plan your finances, but can't take advantage of falling interest rates.
Choose between floating interest rate and fixed interest rate depends on your risk tolerance and financial goals. If you prioritize stability, fixed interest rate is the safe choice. On the other hand, if you want to be flexible and able to withstand fluctuations, floating interest rate will provide cost savings opportunities when the market is favorable.
4. What is a Floating Rate Deposit?
Floating Rate Deposits is a form of depositing money in a bank where the interest rate will change over time, depending on fluctuations in the financial market and the bank's base interest rate. This is a flexible option, helping depositors take advantage of interest rate increases in the market, but can also be at a disadvantage if interest rates decrease.
Floating interest rate deposit products:
- Term deposits:
In this type of deposit, the interest rate can change periodically, such as monthly or quarterly. This helps you keep up with market changes, but can also lead to a change in your return if the bank's base rate changes.
- Non-term deposits:
Demand deposits have a variable interest rate that can change flexibly, allowing you to withdraw your money at any time. This is a convenient and flexible option, but it also makes it difficult to predict the exact return on your deposit.
Example:
Suppose you send 100 million dong into the bank with floating interest rate 6% in the first year. Then the interest rate changes and the bank adjusts it up 7% in the second year. This benefits you as interest rates increase, giving you a higher return than in the first year.
- Year 1: Floating interest rate = 6%
- Year 2: Floating interest rate = 7%
However, if interest rates fall in the second year, you will receive a lower return than in the first year. Therefore, floating rate deposits can bring high returns but also carry risks when the market fluctuates.

5. How to Calculate Floating Interest Rate
Floating interest rates can be calculated in the same way as fixed interest rates, but with adjustments according to interest rate spreadThis margin helps determine the fluctuation of interest rates over the life of the loan or deposit.
Formula for calculating floating interest rate:
Floating interest rate = Base interest rate + Interest rate margin
Example:
- Base interest rate: 6%
- Amplitude: +3%
Floating interest rate will be calculated as follows:
Floating interest rate = 6% + 3% = 9%
This means your floating interest rate will be 9%However, if the base rate changes, your interest rate will change accordingly, possibly increasing or decreasing depending on market fluctuations.
Impact of base rate changes:
- If the base rate increases to 7%, your floating rate will be 10% (7% + 3%).
- If the base rate drops to 5%, your floating rate will be 8% (5% + 3%).
This helps you understand that floating interest rates offer flexibility but can also lead to unexpected changes in borrowing costs or savings returns.
In shortFloating interest rate is a useful financial tool but it also comes with risks. Understanding floating interest rates, floating interest rates on deposits, and how floating interest rates work will help you make smarter financial decisions, optimize borrowing costs, and maximize the return on your savings.
