What Are Basis Points?
Basis points (abbreviated as bps or BPS) represent a unit of measurement in finance equal to one-hundredth of one percent (0.01%). Financial professionals, central banks, and investors rely on basis points to precisely communicate changes in interest rates, bond yields, and other financial metrics where accuracy is critical.

Conversion Formulas
BPS to Percentage
To convert basis points to percentage, divide the BPS value by 100:
250 ÷ 100 = 2.5%
Percentage to BPS
To convert percentage to basis points, multiply the percentage by 100:
1.75 × 100 = 175 bps

Step-by-Step Conversion Process
Converting BPS to Percentage
- Identify the basis points value you want to convert
- Divide this value by 100
- The result is your percentage value
- Add the % symbol to represent the percentage
Calculation: 75 ÷ 100 = 0.75%
Interpretation: Interest rates increased by 0.75 percentage points
Converting Percentage to BPS
- Start with your percentage value
- Multiply this value by 100
- The result is your basis points value
- Add “bps” to represent basis points
Difference: 4.00% – 3.25% = 0.75%
Calculation: 0.75 × 100 = 75 bps
Interpretation: The bond yield rose by 75 basis points

Financial Applications
Central Bank Policy
Central banks like the Federal Reserve use basis points when announcing changes to benchmark interest rates. A 25 bps rate hike means borrowing costs increase by 0.25%.
Bond Markets
Bond yield changes are expressed in basis points. If a 10-year Treasury yield moves from 2.50% to 2.75%, it increased by 25 basis points.
Mortgage Rates
Lenders quote mortgage rate changes in basis points. A rate dropping 30 bps from 6.50% results in a new rate of 6.20%.
Investment Fees
Mutual funds and ETFs express management fees in basis points. A fund charging 75 bps has an annual fee of 0.75% of assets.
Credit Spreads
The difference between corporate and government bond yields is measured in basis points, indicating credit risk premiums investors demand.
Loan Pricing
Commercial loans are often priced as a spread over a benchmark rate, expressed in basis points. For example, “SOFR + 150 bps” means 1.5% above the reference rate.
Real-World Scenarios
The Fed announces a 50 basis point increase to combat inflation. If the previous rate was 5.00%, the new rate becomes 5.50%. This affects mortgage rates, savings account yields, and credit card interest rates across the economy.
Fund A charges 95 bps (0.95%) annually, while Fund B charges 45 bps (0.45%). On a $100,000 investment, Fund A costs $950 per year versus $450 for Fund B, a difference of 50 basis points or $500 annually.
A corporate bond yields 4.80% while a comparable Treasury yields 4.15%. The credit spread is 65 basis points (4.80% – 4.15% = 0.65%), representing the additional return investors demand for taking corporate credit risk.
Why Financial Professionals Use BPS
Precision and Clarity
Basis points eliminate ambiguity when discussing rate changes. Saying “rates increased by 50 basis points” is clearer than “rates increased by 0.5%” because it explicitly indicates an absolute change rather than a relative percentage change.
Avoiding Confusion
If interest rates rise from 2% to 3%, saying “rates increased 50%” (relative) versus “rates increased 1 percentage point” (absolute) can cause confusion. Using “100 basis points” removes this ambiguity entirely.
Standardized Communication
The global financial industry has adopted basis points as the standard unit for discussing small rate changes, facilitating clear communication across markets, institutions, and borders.
Frequently Asked Questions
How much is 100 basis points?
100 basis points equal exactly 1% or 0.01 in decimal form. This is one of the most common conversions in finance, as many rate changes occur in 25, 50, or 100 basis point increments.
Can basis points be negative?
Yes, basis points can be negative when describing rate decreases. For example, “rates fell 75 basis points” means rates decreased by 0.75%. However, it’s more common to say “decreased by 75 basis points” rather than “increased by -75 basis points.”
What is the difference between basis points and percentage points?
A percentage point is simply the arithmetic difference between two percentages, while a basis point is 1/100th of a percentage point. When moving from 3% to 4%, that’s a change of 1 percentage point or 100 basis points.
How do I calculate basis points for a rate change?
Subtract the original rate from the new rate to get the percentage difference, then multiply by 100. For example: New rate 5.75% – Old rate 5.25% = 0.50% difference × 100 = 50 basis points.
Are basis points used outside of finance?
Basis points are primarily used in financial contexts including banking, investing, lending, and economic policy. They rarely appear in other industries because the level of precision they provide is specifically tailored to financial rate discussions.
What is 50 basis points in mortgage terms?
50 basis points equals 0.50% in mortgage rate terms. If a lender reduces rates by 50 bps, a mortgage that was 7.00% would become 6.50%. On a $300,000 30-year mortgage, this could save approximately $90 per month.
