In finance, even small changes in interest rates or yields can have a significant impact. Basis points (bps) are a standard unit of measurement used to describe these changes. One basis point equals 0.01%, making it a precise tool for financial calculations.

What is a Basis Point?
A basis point (bps) is one-hundredth of a percentage point:
- 1 basis point = 0.01%
- 100 basis points = 1%
Basis points are commonly used in:
- Interest rates (loans, bonds, savings accounts)
- Investment yield changes
- Fees and expense ratios in mutual funds
- Financial reporting
Using basis points avoids confusion when discussing small percentage changes.
What is a Basis Point Change Calculator?
A Basis Point Change Calculator is an online financial tool that:
- Converts basis points to percentages and vice versa.
- Calculates the effect of interest rate or yield changes.
- Helps assess the impact of rate fluctuations on loans, bonds, or investments.
- Provides instant results for precise financial planning.
How to Use the Basis Point Change Calculator
- Enter the Initial Value – Input the current interest rate, yield, or percentage.
- Enter the Basis Point Change – Specify the number of basis points increase or decrease.
- Calculate – The calculator will output:
- New percentage after the change
- Absolute difference in value
- Easy-to-read results for financial planning
This simple approach allows users to quickly see how even small changes affect their investments or loan payments.
Formula Behind the Calculator
The basis point change formula is straightforward:
New Rate (%) = Initial Rate (%) ± (Basis Points ÷ 100)
Where:
- “±” depends on whether the rate is increasing or decreasing
- Basis Points ÷ 100 converts basis points to percentage points
Example:
- Initial Rate = 3.50%
- Increase = 25 basis points
- New Rate = 3.50 + (25 ÷ 100) = 3.75%
Example Calculations
Example 1: Interest Rate Increase
- Current Rate: 2.75%
- Increase: 50 bps
- New Rate = 2.75 + (50 ÷ 100) = 3.25%
Example 2: Bond Yield Decrease
- Current Yield: 4.20%
- Decrease: 35 bps
- New Yield = 4.20 − (35 ÷ 100) = 3.85%
Example 3: Fee Adjustment
- Fund Expense Ratio: 1.15%
- Increase: 10 bps
- New Ratio = 1.15 + (10 ÷ 100) = 1.25%
